Technical transformation analysis of steam condensate waste heat recovery via absorption lithium bromide refrigeration unit
The working principle of lithium bromide refrigeration unit for waste heat recovery was introduced.In view of the problem that a large amount of 1.0 MPa(G)steam condensate was directly discharged and its waste heat had not been utilized in Xinrun Company's 600000 t/a oxalic acid to ethylene glycol plant,the technical renovation was carried out,namely the new absorption lithium bromide refrigeration unit system was added to the ethylene glycol refrigeration station,and the waste heat of condensate was used to produce chilled water.After the renovation,the problem of heat energy waste had been effectively solved,which could save 27 405300 kW·h electricity per year,equivalent to saving 3 368.11 t of standard coal and reducing the cardon dioxide emissions of 15 629.24 t.
