Petroleum and chemical industry


Waste hot water and steam from recovery processes (e.g., oil refining, EO/EG, styrene, EVA, polypropylene, caprolactam) are used to drive a lithium bromide unit, producing cold water at or above 5℃ for process refrigeration. For example, in a petrochemical plant, a hot water lithium bromide absorption unit with a total cooling capacity of 41,856 kW recovers hot water heat. Compared to electric refrigeration, with 8,000 hours of annual operation.
