Alstom gets new gas recovery and recycling technology

York, UK - Alstom has installed a new gas recovery and recycling system at its UK research facility in the Midlands. The thermodynamic system, developed by Star Refrigeration Ltd, replaces existing equipment with a more environmentally efficient solution at Alstom, which specialises in the design and manufacture of steam turbines, gas turbines and hydro power plants.

Star¹s dual-purpose system supplies fluorine refrigerant R134a to an R+D test facility. The gas is then recovered and condensed by the system, before it is recycled. The plant features an air-cooled evaporator and condenser in one unit. The evaporator uses ambient air to generate 1000kg/hr of R134a gas from liquid at 3.5 Bar (A).  A reciprocating compressor delivers superheated gas to the R+D test facility at the required pressure.

The gas is later recovered and condensed in an air-cooled condenser. It is then stored as a liquid in a high pressure receiver, before being re-circulated by the system. The system also features a unique Star manufactured purger, capable of removing up to 4kg/h of non-condensable gases. The plant is operated byTelstar, Star¹s patented computerised control system.

Alstom¹s innovative system was developed in consultation with Star¹s technical advisory arm, Star Technical Solutions (STS). STS operates as an independent consultancy, working alongside Alstom from the design stage through to commissioning. Star-owned mechanical and electrical contractor Penec was responsible for the removal of the existing electrical system and also completed the installation of new electrical panels and wiring.
