R-410A TO REPLACE HCFC-22 IN A REFRIGERATION UNIT FOR A BRITISH LPG SITE

A LPG site refrigeration system using HCFC-22 – under a British government temporary exemption to the EU service ban for HCFC-22 - has recently been converted to the refrigerant R-410A.

In the process of identifying alternatives to HCFC-22, an ammonia/CO2 system was found to be technically unfeasible, R-507, with a too high GWP of 3,985 is subject to a service ban from 2020, for virgin refrigerant for this application in line with the EU F-Gas Regulation 517/2014, so that R-410A emerged as the only economically and technically feasible alternative.

The HCFC-22 temporary exemption was granted due to the importance of the LPG facility for the Forties pipeline system, which delivers approximately 25% of the UK gas production.
