NATURAL GAS LIQUID FRACTIONATION PLANT WASTE HEAT CONVERSION TO SIMULTANEOUS POWER, COOLING AND POTABLE WATER USING MODIFIED GOSWAMI CYCLE AND NEW MODIFIED MULTI-EFFECT-DISTILLATION SYSTEM

摘要

Certain aspects of natural gas liquid fractionation plant waste heat conversion to simultaneous power, cooling and potable water using modified Goswami Cycle and new modified MED system can be implemented as a system. In an example implementation, the system includes a waste heat recovery heat exchanger network coupled to multiple heat sources of a Natural Gas Liquid (NGL) fractionation plant, the heat exchanger network configured to transfer at least a portion of heat generated at the multiple heat sources to a first buffer fluid and a second buffer fluid flowed through the first heat exchanger network. The system includes a first sub-system configured to generate power and sub-ambient cooling capacity, the first sub-system thermally coupled to the waste heat recovery heat exchanger. The system includes a second sub-system configured to generate potable water from brackish water, the second sub-system thermally coupled to the waste heat recovery heat exchanger.
