Project Value: £9,000 Project Elements Environment Permit compliance Energy Efficiency Review Best Available Techniques (BAT) benchmarking Improvement Opportunities Identification of measures to reduce CO2 emission equivalents Gap Analysis of current management plan
Basic and further energy efficiency techniques
CRA provides a range of services to the gas refining industry in the UK, including the performance of 4-year energy efficiency reviews to satisfy the conditions of the installation’s Environmental Permit. The reviews are undertaken to identify opportunities to improve energy efficiency for process and non-process applications at the permitted installations. Data on energy consumption and productivity is examined, the status of existing energy efficiency actions reviewed, and current energy management techniques assessed. Opportunities to improve energy efficiency are identified and included in an Energy Efficiency Plan. In this recent review, energy efficiency measures for the installation amounted to an estimated CO2 emissions saving of greater than 4000 tonnes per annum, which is 8.2% of estimated direct and indirect CO2 emission equivalents (2011) for the site. A gap analysis was undertaken of the current Greenhouse Gas and Energy Management Plan against the Environment Agency (EA) Horizontal H2 Guidance on Energy Efficiency. This investigation identified additional information required by the EA Guidance over the Site Control Framework. In accordance with the H2 Guidance, the review included basic energy efficiency techniques and further energy efficiency techniques including:
Assessment of basic energy requirements Assessment of operations, maintenance and housekeeping measures Assessment of site buildings and facilities energy consumption and efficiency Opportunities for heat recovery Water minimisation Low energy technology Optimised design and layout Process control and layout Specification of equipment Assessment of energy supply techniques Development of an energy efficiency plan including impact on projected CO2 equivalent emissions.
It was demonstrated that the operator was applying the Best Available Techniques (BAT) to manage energy efficiency and achieving a specific energy consumption (energy consumption/tonne product) below the range for this sector detailed in the European IPPC Bureau’s BAT Reference Document (BREF) for the Refining of Mineral Oil and Gas (Draft 2) March 2012.
