A water treatment system of coupling a heat pump with multi-effect evaporation that comprises a lithium bromide absorption-type heat pump circulation system, a multi-effect evaporation circulation system and a compression-type heat pump circulation system is provided. The vapor in a tail-end evaporator of the multi-effect evaporation circulation system is introduced into a generator in the absorption-type heat pump to release heat and condense. A dilute solution in an absorber of the absorption-type heat pump is introduced into a first-effect evaporator to be evaporated by a treated water, and a condensation heat of the vapor generated by the generator of the absorption-type heat pump is recovered by an evaporator of a compressor heat pump, and another air source evaporator absorbs heat from ambient air to supply heat for the generator by a heat pump condenser.

Liquefaction of industrial gases or gas mixtures (hydrocarbon and/or non-hydrocarbon) uses a modified aqua-ammonia absorption refrigeration system (ARP) to chill the gas or gas mixture during the liquefaction process. The gas is compressed to above its critical point, and the heat of compression energy may be recovered to provide some or all of the thermal energy required to drive the ARP. A Joule Thomson (JT) adiabatic expansion process results in no requirement for specialty cryogenic rotating equipment. The aqua-ammonia absorption refrigeration system includes a vapour absorber tower (VAT) that permits the recovery of some or all of the heat of solution and heat of condensation energy in the system when anhydrous ammonia vapour is absorbed into a subcooled lean aqua-ammonia solution. The modified ARP with VAT may operate at pressures as low as 10 kPa, and the ammonia gas chiller may operate at temperatures as low as −71° C.
