NATURAL GAS LIQUID FRACTIONATION PLANT WASTE HEAT CONVERSION TO SIMULTANEOUS POWER AND COOLING CAPACITIES USING INTEGRATED ORGANIC-BASED COMPRESSOR-EJECTOR-EXPANDER TRIPLE CYCLES SYSTEM

摘要

Certain aspects of natural gas liquid fractionation plant waste heatconversion to simultaneous power and coolingcapacities using integrated organic-based compressor- ejector-expander triplecycles system can be implemented as a system. Thesystem includes a first waste heat recovery heat exchanger network thermallycoupled to multiple heat sources of a Natural Gas Liquid(NGL) fractionation plant. The first heat exchanger network is configured totransfer at least a portion of heat generated at the multipleheat sources to a first buffer fluid flowed through the first heat exchangernetwork. The system includes an integrated triple cycle systemconfigured to generate cooling capacity to cool one or more heat sources ofthe plurality of heat sources. The system includes a secondwaste heat recovery heat exchanger network thermally coupled to the integratedtriple cycle system, and configured to vaporize at leasta portion of a second buffer fluid flowed through the integrated triple cyclesystem.
