Pakistan State Oil Company Ltd., Rehabilitation of LMT HVAC & Heat Recovery System

2 MW cogeneration plant. Waste heat of 2 gas engines is used to produce chilled water for the process needs and air conditioning of the Lube Manufacturing terminal at Korangi. During feasibility study, various options were explored and their financial results and other technical details were shared with the client along with clear recommendations. Selected option is based on multi-energy direct exhaust fired absorption chillers. Only one type of chiller is able to handle the exhaust gases and HT circuit water heat of engines. Moreover it has a dual fuel burner to provide chilling via natural gas or diesel in case of non-operation of the gas engines. Day load is about 1040 kW and we are able to get 250-270 TR.
