Pressure Regulation

Regulator Designation

Flowrate Coefficients

calculation of flowrate coefficients The valve flowrate coefficient KG is an important parameter for the choice of RMG gas pressure regulators The KG-value indicates the flowrate of the valve in full open position under an absolute inlet pressure of pe = 2 bar and an absolute outlet pressure of pa =1 bar. The KG-value is determined under standard conditions on a test stand with air as a gaseous medium. The KGvalue is a factor which indicates the flowrate capacity of a gas pressure regulator. All KG-values stated in the RMG-leaflets refer to natural gas as a flowrate medium (ﾏ］ = 0.83 kg/m3). The diagram on page 15 shows the graphic method to determine the flowrate coefficient KG required for given service data of min. inlet pressure max. outlet pressure max. flowrate

pe min pa max qn max

This graphic determination is based on the following formulas for approximate flowrate calculation valid for natural gas: flowrate coefficient KG for subcritical pressure drop

Pressure Regulation

Regulator Designation

Flowrate Coefficients

Note!

The flowrate coefficient of the regulator chosen should always be higher than the flowrate coefficient determined from the diagram or calculated through the formulas in order to ensure sufficient reserve capacity for the regulating operation. We recommend to choose a regulator with a flowrate coefficient of approximately 10% above the required value.

Attention!

For regulators with internal measuring impulse the gas velocity in the outlet duct (measuring point of outlet pressure) should not exceed v = 20 m/s. Please also refer to the „General Operating Instructions for Gas Pressure Regulators and Safety Devices, Examples of installations“ (extract see page 372)

In the general regulating and metering terminology the flowrate capacity of a valve canalso be indicated by its kvs-value. The relation between kvs and KG is given in ithe following equation:

KG = 34 · kvs

regulator

characteristic features No permanent regulating inaccuracy. Slow valve position reaction, to be mounted in horizontal position only. Setpoint adjustments are difficult. Regulators of moderate price, quick valve position reaction, can be mounted in any position, easy change of setpoint adjustments. No automatic correction of regulating inaccuracies, relatively low outlet pressures. Suitable for large inlet and large outlet ranges, high pressure drops and high flowrates; high regulating precision, easy change of setpoint adjustments. A minimum pressure differential between inlet and outlet pressure is required to open the valve. Valve position reaction not so quick as reaction of spring-loaded regulators. More expensive and technically more sophisticated than spring loaded regulators.

I.e. the diameter of the throttle and the SBV-orifice are fixed so that more gas is always relieved to the atmosphere through the safety relief valve stage than can penetrate into the device, even during failure conditions. Therefore, an uncontrolled increase of the outlet pressure is avoided in case of defects.

Pressure Regulation

Maximum Inlet Pressure

Series 300 and 400

Inlet pressure range ∆pe (max. inlet pressure) for diaphragm assemblies The accuracy class AC and the lock-up pressure class SG stipulated by the DVGW type tests are confirmed under the following conditions: „The inlet pressure may exceed the ∆pe-figure stated in the table at the most by twice its value, provided the inlet pressure deviations ∆pe do not exceed the pe max-value stated in the table. However, it may not exceed the nominal pressure rating.” ATTENTION: This statement is not valid for RMG 409 with pe > 25 bar. The limitation of the inlet pressure range ∆pe for a diaphragm assembly is not given for reasons of material strength but in the interest of maintaining the regulating accuracy. The inlet pressure deviations though may not exceed the limit of the valve´s nominal pressure rating.

Pressure Regulation

Maximum Inlet Pressure

Series 300 and 400

Example: RMG 330, DN 50, valve seat diameter 33 mm, diaphragm assembly size 1 (see page 57). The table shows an inlet pressure range of ∆pe = 10 bar, so the inlet pressure may deviate in a range of 10 bar up and down. Beginning with the given deviation range between 0 bar and 10 bar, this ∆pe -range may be transferred to a higher level. The maximum inlet pressure (value stated in brackets) though may not be exceeded. The permissible inlet pressure change ∆pe = 10 bar can be used as follows: A possible inlet pressure variation of pe1 = 0 bar to pe2 = 10 bar is standard, but equally an inlet pressure deviation of pe1 = 2 bar to pe2 = 12 bar could be possible, or a deviation of pe1 = 6 bar to pe2 = 16 bar. In every case the valve´s regulating accuracy is maintained. Should however the inlet pressure deviations be larger than the stated ∆pe-value, then the regulating accuracy will become poorer. ATTENTION: The inlet pressure deviations may never exceed the limit of the valve´s nominal pressure rating.

The scheme shows how the inlet pressure range ∆pe may be transferred for this example:

pe max 16 bar

10 bar

6 bar

electronic steering

electronic steering for flow control valve RMG 530 RMG offers different types of actuators and electronic regulating systems for driving the flow control valve RMG 530. RMG has different certificates of conformity and expertsÂ´ declarations approving the installation of those functional units into explosion-hazardous areas. All actuators are controlled by the automation system Protronic 500 and the customerspecified RMG-software, which monitors all the important measuring data, setpoints and control signals. Should the set ranges be violated, then preventive measures are initiated by the automation system (these are generally pre-set by the customer).

All service and fault indications are shown in the LC-display as clear-text information. Selected messages can be forwarded for remote indication. Due to their individual construction, RMG flow control valves have different opening and regulating characteristics. These characateristics were determined in testing fields and integrated into the software of the automation system as additional functions to optimize the regulating behaviour.

The pneumatic pressure stages automatically check the given minimal and maximal values of the outlet pressure. If those max. values are reached during operation, the relevant stages take over control and hold the pressure constant within the given limits. The switching between the electronic control (operated by the electro-pneumatic control stage) and the outlet pressure restriction through the pneumatic control stages runs independantly and smoothly in both directions without any noticeable transition effects. The following tasks can be realized between the min. and max. pressure limits: â?&#x2018; setpoint adjustment - for a quick adapation of the setpoint to often changing operational conditions - for combining the regulator into a process control system â?&#x2018; flow regulation - for gas storage in tube networks and tanks (optimization) - for meter protection â?&#x2018; pressure regulation - combined with meter protection through flow limitation to qB max - with timer for daily/weekly programme for pressure control - to reach a better control accuracy and control stability through an electronic PI-regulation approved by DIN-DVGW in combination with RMG main valves, the pilot is part of the complete device according to DIN 3380 pulse modulator RMG 110 see page 132

Series 600 - station automation

RMG Station Automation Nowadays the trend goes away from the classical pneumatical regulation with electric long-distance setpoint adjustment to modern station automation technology. Gas pressure regulators are thus combined more and more into remote control systems for natural gas distributing networks. RMG offers system solutions adapted to customersÂ´ requests. From simple outlet pressure control to complete station management, anything is possible with RMGÂ´s easy-to-connect modules! In co-operation with the customer, RMG works out performance specifications which are set into practice by our experienced programmers. Before going into everyday use each system is tested intensively in our trial field. Initiation time on site is thus reduced considerably.

accomplish all automized tasks desired in natural gas distributing stations. The compact pilot system combines all the advantages of freely programmable and conventional process management systems.

Engineeringstation

The functionality and quality of regulation as known in the RMG automatisation system SCS 2001 (Protronic 500/550) and in use successfully several hundred times - can be integrated completely into the SCS 2500. Standardized programming codes acc. to IEC 1131-3 and the close resemblance between Freelance 2000 and Protronic 500/ 550 reduces the necessary programming to a minimum. This also cuts down engineering costs considerably. The user interface of the process management system was adapted to the needs of gas offtake stations.

That is why -under certain conditions, such as are given by a high inlet pressure or a high pressure cut- it is necessary to preheat the gas. Rough estimation of the heat needed for natural gas preheating:

W = qn · ∆tges · ρn · cp in kJ/h

W qn ∆ tges ∆ t1 ∆ t2 cp ρn Example: given:

= = = = =

heat quantity in kJ/h gas volume or flowrate in m3/h total temperature = ∆ t1 + ∆ t2 in K Joule-Thomson-Effect = (pe-pa) 0,5 in K temperature differential between minimum gas inlet temperature and temperature required after gas pressure reduction in K = specific heat of natural gas 2,2 kJ/kg = specific gravity of natural gas= 0,831 kg/m3

gas flowrate inlet pressure outlet pressure gas inlet temperature required gas outlet temperature

qn = 5000 m3/h pe = 70 bar pa = 4 bar tE = 273,16 K tA = 278,16 K

∆ t2 = tA-tE : ∆ tges = ∆ t1 + ∆ t2 = (70-4) · 0,5 + 5 = 33 + 5 = 38 K W = qn · ∆ tges· ρn · cp = 5000 · 38 · 0,831 · 2,2 = 347358 kJ/h Considering a preheating efficiency factor η = 0,85 the required heat quantity comes up to W = 408650 kJ/h.

What is burnable gas?

A gas or gas mixture that is burnable in a determined mixing proportion with oxygen.

Which are the most important burnable gases?

Natural gas, coke oven gas, town gas.

What is natural gas?

A natural product.

How does natural gas originate?

From animal and vegetable deposits on the bottom of the seas which -during millions of years- are chemically transformed into hydrocarbons under the high pressure exerted by rock formation and ground deposits.

What does natural gas consist of?

Mainly of the burnable methane compound (CH4).

Since when do we know about natural gas?

About 5 000 years ago the Indo-Europeans in the Caucasus found natural gas emanations to be the â&#x20AC;&#x17E;Eternal Fireâ&#x20AC;&#x153;. Sumeric and Assyrian priests interpreted the gas emenating from the earth for their future tellings.

When was natural gas utilized for an economic purpose for the first time?

According to British chronicles the Chinese utilized natural gas for the drying of salt about 900 before Christ.

Where and when was the discovery of the first natural gas field?

In the saltmine in Charleston, West Virginia, in 1815.

..and in Germany?

At a water bore-hole in Neuengamme near Hamburg, in 1910.

When was the first long distance On August ThyssenÂ´s initiative the first German long gas transmission pipeline built in distance gas transmission pipeline was built from Germany? Duisburg-Hamborn to Wuppertal-Barmen in 1910. In 1964 the German pipeline system was connected to the natural gas network of the Netherlands, and in 1974 linked to the pipeline from Russian gas fields. These were the starting points of an all-European gas transmission and distribution system. Which are the main types of gas Main transmission pipelines, also referred to as long mains, and which are their distance gas transmission lines are high pressure service pressures for gas pipelines for a maximum transmission pressure of 80 bar. transmission? The regional and local gasboards supply the gas to the end consumers through medium and low pressure lines 402 with a minimum supply pressure of 20 mbar.

Basics, Definitions, and Conversion Tables

useful information

What is an offtake station?

A regulating and metering station designed to reduce the gas pressure to the level of the downstream mains and to meter the gas flow „handed over“ or „taken off“.

Why do we store natural gas?

As the natural gas consumption is subject to daily and seasonal fluctuations of considerable extent, it is an economic necessity to store natural gas during periods of low demand in order to secure the gas availability for periods of high or peak demands.

How do we store natural gas?

In gaseous condition. Above ground holders are used to store the gas for daily compensation of lacks of small quantities. Large gas quantities are placed in underground storages of porous rocks or in salt caverns.

Which are the main natural gas types and qualities?

We distinguish between 2 types of natural gas referred to as type L and H. „L“ stands for „low“, meaning that this type of natural gas has a combustion value of approximately 10 kWh/m3. This gas comes from Dutch of German fields. „H“ stands for „high“, meaning that this type of gas has a combustion value of approximately 11 ...12 kWh/m3.

What does DVGW mean?

„DVGW“ is the abbreviation of „Deutscher Verein des Gasund Wasserfaches“ - Technisch Wissenschaftlicher Vereinigung“. Its residence is Eschborn near Frankfurt/ Main.

What is DIN-DVGW registration of a gas pressure regulator or a safety device?

A DIN-DVGW registration number for a gas pressure regulator or a safety device proves that this type of regulator or safety device has been tested and approved of by a recognized test authority. The regulator or safety device meets the requirements laid down in DIN Standard DIN 3380 and DIN 3381.
