摘要:
Two or more open cycle vapor compression heat pumps of interdependently different capacities are placed in parallel arrangement intermediate a heat sink and a heat source for the transfer of sensible heat therebetween.
摘要:
Systems and processes for heat recovery associated with the separation of hydrocarbon components. Two compressors are used to compress a portion of an overhead vapor stream from a fractionation column. A pressure of the liquid portion of the compressed overhead is reduced and used to recover heat from an overhead of another separation zone having a fractionation column. Once the heat has been recovered the stream is recompressed. The recovered heat may be removed from the recompressed stream in a reboiler of another fractionation column. The fractionation columns may comprise a deethanizer stripper, propane-propylene splitter, and a depropanizer column.
摘要:
A system for thermal desalting of water in an adiabatic evaporator with condensation of the secondary steam is characterized in that it includes a steam turbine with a condenser which is connected through pipelines with an adiabatic evaporator and a water-to-water heat exchanger forming a circulation water cooling system.
