meets with UKOOG

BPMA met with the United Kingdom Onshore Operators Group (UKOOG) in June to discuss the pump supply chain associated with potential UK shale gas developments A new UKOOG commissioned survey shows 57% of Britons support natural gas from shale • 57% of Britons think shale gas production should go ahead; only 16% are opposed • Two thirds believe Britain should be less reliant on gas from other countries • Planned changes to underground land access supported by 42% of the public, with only 16% opposed A new public opinion poll reveals that natural gas production from shale enjoys widespread backing across the country, with more than three times as many supporting production than opposing. The Populus survey of 4,000 adults, commissioned by UK Onshore Oil and Gas (UKOOG), also finds overwhelming support for reducing Britain’s reliance on gas imports from overseas, which are rising rapidly as North Sea production declines. This survey is one of the largest polls on the issue. The key findings of the research include: • Overall support for shale gas production: 57% support the production of

natural gas from shale in the UK, compared with 16% who oppose and 27% who are undecided. • Reducing reliance on gas imports: 67% agree that Britain needs to produce its own energy so it isn’t reliant on gas from other countries, compared with just 1% who disagree. National Grid has forecast that without natural gas from shale production, Britain will import up to 91% of its gas by 2035. • Support for shale gas development alongside renewable energy: 59% would be willing to see natural gas from shale production go ahead as long as it forms part of a mix that includes renewable energy sources, with only 12% disagreeing. • New infrastructure needed: 47% agree that the UK needs to invest in a whole range of new infrastructure, including housing, roads and railways, airport capacity and new energy sources, with only 5% disagreeing. • Underground land access: 42% agree with the Government’s planned changes to underground land access, compared with 16% who disagree. The changes are designed to bring oil and gas and geothermal energy production into line with other essential services that have rights of underground access, including water and sewage pipelines and coal mines.

NEWS BYTES   Government publishes CCS scoping document The Government today reaffirmed its commitment to the establishment of a Carbon Capture and Storage (CCS) industry in the UK with the publication on 7 August 2014 of a scoping document which summarises the policies and actions the Government has taken as part of its world leading programme. The “Next Steps in CCS: Policy Scoping Document” also sets out the Government’s intention to continue engagement with the CCS industry and seeks views and evidence on a possible Phase 2 of CCS deployment, taking forward commitments published in the 2013 Electricity Market Reform Delivery Plan. Secretary of State Edward Davey said: “The UK is leading the world on CCS and the Government wants to make sure that Britain will be in first place to export this knowledge to a decarbonising global economy.” “The Government is strongly investing in developing a CCS industry in the UK that can compete on cost with other low carbon technologies. CCS will help us reach our goal of reducing carbon emissions by 50 per cent from 1990 levels more cheaply by while supporting over 15,000 jobs per year.” The Government is already investing around £100m in the Front End Engineering and Design (FEED) stages of two CCS projects - White Rose and Peterhead, as part of its £1bn CCS Commercialisation Programme. Taken together, the Peterhead and White Rose projects could provide over 2000 jobs during construction, reduce the UK’s carbon emissions by around 3 million tonnes a year, and provide clean electricity for over 1 million homes. The White Rose project also recently received e300m in funding from the European Commission under their NER300 programme and was the only CCS project in all of Europe to receive this support. The document invites views by 23 October 2014.

 The Energy Savings

Opportunity Scheme (ESOS) and Pump System Audits

The Energy Savings Opportunity Scheme (ESOS) Regulations 2014 came into force on 17 July 2014 and are a mandatory energy assessment and energy saving identification scheme for large undertakings (and their corporate groups). The scheme applies throughout the UK. ESOS Energy Audits have the potential to increase businesses profitability and competitiveness by identifying cost-effective savings which, if implemented, will improve energy efficiency. The scheme is estimated to lead to £1.6bn net benefits to the UK, with the majority of these being directly felt by businesses as a result of energy savings. ESOS is the UK Government’s approach to transposition of Article 8(4) of the EU Energy Efficiency Directive, which requires all large (non-SME) enterprises to undertake energy audits by 5 December 2015 and every 4 years thereafter. The scheme’s regulations are published on the government’s legislation website http://www.legislation.gov.uk/uksi/2014/1643/contents/made More information about the Energy Savings Opportunity Scheme can be found on the ESOS webpage https://www.gov.uk/energy-savingsopportunity-scheme-esos Guidance has also been published to help potential participants in the scheme understand their obligations and on page 43 of the full ESOS guidance document you will see that the ISO/14414-Pump System Energy Assessment standard is referenced as an auditing methodology that can be accepted by “Lead Assessors” approved by the Environment Agency. Accordingly it is hoped BPMA CPSA accredited persons (who are trained according to the IS0 14414 standard) will be recommended by Lead Assessors to undertake the pumping system elements of company energy audits. And bear in mind:• Pumps are the largest consumers of global motive power • Pumping System improvements can deliver up to 40% reduction in energy costs – and therefore improve user bottom line P&L account performance • The fact that BPMA’s CPSA scheme has been designed to help by equipping people with the skills to conduct a Pumping System Audit in accordance with ISO/14414 So when considering auditing your pumping systems, remember the BPMA Certified Pump System Auditor Scheme (http://www.bpma-cpsa. co.uk) has established BPMA as THE body to train and certify personnel who undertake “Pumping System Assessments” as referenced in UK Government Energy Strategy documents. BPMA are now offering the opportunity to attend a four day residential course culminating in certification and eventual personal ID “Certified Pump System Auditor” status following approved audits.

When Pressurised just call Smedegaard the Pressurisation system experts Smedegaard Pumps limited manufacture and supply what is ‘probably’ the largest range of pressurisation equipment for LTHW, MTHW and CWS systems. The standard ECO and Elite pressurisation units are primarily designed for commercial systems and are used with Expansion Vessels. The units can be free standing or walls mounted, and are Category 5 compliant. Elite units are fitted with system ‘safe fill’ packs allow the units to fill the closed loop system. For applications such as very large volume, high rise, higher temperature systems or where the final working pressure of the system must be similar to cold fill pressure then the SpillPress units offer the ideal solution. The compactness of the SpillPress units may also be a great advantage where the available floor space is limited. SpillPress tanks are designed to accept the full expansion of the system; level control is fitted as standard. All tanks have an overflow and spill over weir to give a WRc Category 5 compliant type AB air gap. A full digital control panel is fitted to the unit which gives an audible and visual alarm indication with mute, password protection and hours run log and has volt free contacts for BMS connection. SpillPress are split into three distinct ranges each providing the optimum engineered solution.

SPILLPRESS COMPACT The ‘Compact’ range consists of the pump and control module

mounted together with the spill tank on a common base plate. Peripheral turbine pumps in twin configuration are normally used in the range. However, other pumps can also be offered to suit specific requirements. The spill tanks are available in three sizes to accept 400 litres, 600 litres or 1000 litres of expansion. Solenoid valves are utilised as spill valves on this range.

SPILLPRESS MODULAR

The ‘Modular’ range consists of the pump and control module on a common baseplate and the spill tank supplied loose. Usually two vertical multistage pumps are fitted but there is the option for a third pump. Self acting spill valves are utilised with this range but solenoid valves can also be fitted to this range. ‘Modular’ packages can accept expansion of up to 11875 litres and is suitable for use with boilers of up to 12000 kW at 90°C.

SPILLPRESS BESPOKE The ‘Bespoke’ range is designed and engineered for larger projects which exceed the capability of both the ‘Compact’ and ‘Modular’ packages. The ‘Bespoke’

sets are designed and built to the client’s specific specifications with the aid of our in house expertise. The accompanying picture shows a ‘Bespoke’ custom built pump and control package. Spill tanks with a capacity of 53,000 litres were provided with this package. High Temperatures Applications When operating the system above 95°C higher pressures will be required to eliminate vaporisation. Additionally intermediate cooling buffer vessels may be necessary. As the SpillPress for these applications is customised to specific needs, please contact the Smedegaard technical team for assistance when dealing with these system types.

Glasgow keeps up the pace With significant medal hauls for all the home nations and huge television audiences, it is acknowledged that Glasgow hosted a very successful games this summer. Almost as famous as the stars who won medals, many of the venues were also basking in the spotlight of success and were the subject of a lot of media attention as well as much well deserved praise. One such venue was the Sir Chris Hoy Velodrome and the Emirates Arena that hosted the cycling and badminton respectively. The wide range of energy efficient pump solutions supplied by Grundfos delivered all of the HVAC needs to these venues, as well as ensuring that the all water boosting requirements were met. Grundfos also supplied the fire suppression system that will continue to keep these venues safe and secure for the next generations of athletes who will pass through these sporting portals. Post games, clever engineering and the integration of hydraulics means this venue can also be transformed into a 200 metre, 6 lane athletes track as well as being capable of playing host to badminton, netball and basketball fixtures. All of which means that this centre will continue to service the local, national and international demands, for many years to come, as will all the supporting Grundfos pumps.

GSPX Takes To The (Multi) Stage Why have three pumps when you can have one? High head performance is now available in a sealless, easy to install, compact package following the launch of the new GSPX pump from Sundyne HMD Kontro. A multi-stage derivative of HMD’s long established GSP range, the GSPX uses a between bearings design (BB5) for the second and third stage impellers and delivers space and servicing efficiencies plus lower costs than using multiple single stage pumps in series. Conforming to API 685, the pump produces higher differential pressures than single stage models and is ideal for oil and gas installations, typically refineries, as well as for other chemical and petrochemical applications. The GSPX is available with two or three in-line stages, two diffuser based hydraulic options and in an end suction configuration, ideal for fitting inducers in very low NPSHA installations. Further efficiencies can be gained via the optional ZeroLoss composite containment shell, which eliminates coupling losses and heating of the process liquid. Fully draining and self-venting, the GSPX’s commonality with the GSP range delivers maximum convenience with interchangeable components and is available in a range of materials, including bespoke engineered options that allows a multistage pump solution to be tailored to specific requirements. Sundyne HMD Kontro has more than twenty-five years’ experience in API applications and is continuously developing and extending its range, as improved magnet drive technology enables ever more efficient and powerful pumps to be built, widening the application scope of this versatile pump format. For more information on the GSPX range please see the website at www.sundyne.com/hmdkontro.

NOV Mono has delivered a turnkey project to provide an extra level of protection for a major water and waste treatment plant in Pembrokeshire, Wales. The project centers on an EZstripTM progressing cavity pump which is now being used on sewage transfer duties to ensure that the plant can guarantee the quality of the treated sewage under any flow conditions. Powered by a 4kW motor and operating at a duty speed of 226 rpm, the EZstripTM pump draws sewagefrom the centre of the final settlement tank at Dwr Cymru’s Crymych treatment plant. It pumps the sewageback up to the head of the treatment system, from where it returns back through the filter bed to the final tank. This ensures that the plant’s biological filters do not dry out and remain effective, even in very low flow conditions. This in turn helps to maintain the quality of the final sewage within the required boundaries, at all times. MonoTM was approached because of its ability to provide a full turnkey package which covered all the stages, from initial site survey, design and manufacture, through to full mechanical and electrical installation. Working closely with the project’s civils contractor, Mono installed the pump, suction pipe, rising main, control panel, overpressure and high temperature devices and completed the final testing and commissioning. Both the electrical and mechanical work were handled by Mono, who have since completed a very similar project at Dwr Cymru’s Lamphey treatment plant. The progressing cavity pump at the centre of the Crymych project features Mono’s revolutionary EZstripTM design which allows it to be maintained-in-place. This provides a quick and easy way to disassemble, de-rag and maintain the pump without the need to disconnect suction and discharge pipework. This reduces a typical day-long maintenance operation down to just 30 minutes. Available in cast iron or stainless steel, and with a choice of rotor and stator materials, the pump requires only basic tools to maintain, and can be retrofitted into existing installations where a Mono Compact C pump has been used previously.

Watson-Marlow pumps replace AOD models at paper bag mill Gloucestershire-based Stonehouse Paper & Bag Mills Ltd has installed three 500 series process pumps from WatsonMarlow Pumps Group in replacement for diaphragm pumps that were proving hard to clean, difficult to maintain and expensive to run. The success of the WatsonMarlow 521VI/R2C peristaltic pumps in recirculating inks on the company’s printing presses, has led Stonehouse to order a further two identical models. In fact, the company plans to replace all of its existing diaphragm pumps with Watson-Marlow models as and when their performance starts to dip.

Cost effective “When we were looking for new pumps, our research revealed that electrically operated pumps would be more economic and easier to use than the air-operated diaphragm pumps with which we had become familiar,” says Jonathan Daniels, the company’s Managing Director. “All compressed air systems have leaks, which basically means you

are using energy even when the pump isn’t running. There are no such worries with an electric pump. Furthermore, changing the diaphragm and valves in an AOD pump is best done by an octopus, whereas access and tube loading on the WatsonMarlow pump couldn’t be easier.” On the Watson-Marlow 521VI/ R2C, the pumphead set-up using two-position, sprung-loaded tube clamps and clutched rotor makes tube loading effortless. Mr Daniels also says that the robust build of the pump helped differentiate it from others on the market. Here, heavy duty construction with impact-proof safeguarding and robust tube clamps ensure grip even in poor operating environments. Furthermore, the 520R2C pumphead features a polyphenlene sulphide (PPS) track and rotor, with stainless steel occlusion rollers to resist chemical attack and abrasive wear.

Ink circulation The pumps at Stonehouse are used to circulate inks on the printing presses, some of which use a ‘chamber blade’ system. This, in combination with the pump, fills a pot with ink (the pot has an overflow), constantly agitating it to keep the colour consistent “If the pump is running too fast, or the pressure is wrong, there’s a real danger that thinner inks will leak everywhere,” explains Mr Daniels. “However, with the variable speed inverter on the WatsonMarlow 521VI/R2C, we can slow things down to negate this issue.”

In control Mr Daniels says that a further advantage of the WatsonMarlow pump is that it’s possible to ‘back-pump’ using reverse control to extract all of the ink from the tube and save it going all over the floor when changing over. “In theory we could have a tube for each colour because changeover is so easy,” he says. “In reality, however, we’re running all the colours of the rainbow and every shade in between, so we have to cleandown between print runs. It’s just a case of washing through with water – using the inverter on the Watson-Marlow we can wash through at whatever speed we want.” In contrast, Mr Daniels says that the diaphragm pumps are hard to keep impeccably clean. They feature their own vessel into which ink is poured – this has to be poured back out at the end of the run, creating downtime.

Further orders The three Watson-Marlow 521VI/R2C pumps have been working at Stonehouse since 2005. Such has been their performance that the company has now placed an order for two more. “Not only have the pumps proved reliable, but Watson-Marlow are very knowledgeable and have been extremely helpful,” says Mr Daniels. “As and when other diaphragm pumps stop being reliable we will replace them with Watson-Marlow.” Stonehouse Paper & Bag Mills Ltd is an independent, family run business that was established in 1922 and continues to run from its original location next to the River Frome in the Cotswolds. The 18-employee company’s main activity is manufacturing from a range of paper substrates from the reel into plain or printed bags measuring from as small as 1” wide x 1” long up to a length of 55” and in volumes of 5,000 upwards. Stonehouse differentiates itself in the market by manufacturing paper bags to exact customer dimensions, rather than having to opt for the nearest size available.
