RECIRCULATION FEASIBILITY STUDY PROVIDING ENERGY REDUCTION OPPORTUNITIES AT API R&D FACILITY
PROJECT BRIEFFollowing identification of a potential project in the ESOS report, EECO2 Ltd was appointed to carry out a detailed feasibility study, for the recirculation of air from the exhaust system back to the supply air handling unit (AHU) at this API R&D facility. The AHU is 100% fresh air unit and therefore a significant energy consumer for both electricity and steam. The area had potential solvent release, so the solution needed to have appropriate safety and control measures.
The scope of the detailed feasibility study was customised to suite the needs of the project, including; refined energy calculations, schematic design works coordinated with respect to a complicated plant area and most importantly, open discussions with site engineering, safety and quality teams on proposed solutions.
The outcome of the study identified a number of potential options to deliver reduced airflow (air change rate reduction) and partial recirculation linked to space sensors, allowing excess air during any emergency events.
The report concluded that with a structured, risk-based approach, energy savings of £80,000 per year can be delivered, with a payback less than 2 years. API facilities have great potential for improving safety monitoring while achieving more efficient HVAC operation following a systematic risk-based approach to project development.
