Abstract
A method of heat recovery from a Natural Gas Liquid (NGL) fractionation plant for generating power and sub-ambient cooling, the method including heating a buffer fluid in a heat exchanger with heat from the NGL fractionation plant, and generating power and sub-ambient cooling via a sub-system having a power turbine with heat from the buffer fluid.
Claims28
A method of heat recovery from a Natural Gas Liquid (NGL) fractionation plant for generating power and sub-ambient cooling, the method comprising:
- heating a buffer fluid in a heat exchanger with heat from a NGL fractionation plant comprising a distillation column.
- discharging the buffer fluid from the heat exchanger via a collection header conduit to a sub-system comprising a power turbine;
- and
- generating power and sub-ambient cooling via the sub-system with heat from the buffer fluid.
A method of heat recovery from a Natural Gas Liquid (NGL) fractionation plant for generating power and sub-ambient cooling, the method comprising:
- heating a buffer fluid in a heat exchanger with a discharge stream from a dehydrator column in the NGL fractionation plant, wherein the dehydrator column comprises a propane dehydrator column or a butane dehydrator column;
- discharging the buffer fluid from the heat exchanger via a collection header conduit to a sub-system comprising a power turbine;
- and
- generating power and sub-ambient cooling with heat from the buffer fluid via the sub-system.
A method of heat recovery from a Natural Gas Liquid (NGL) fractionation plant for generating power and sub-ambient cooling, the method comprising:
- heating a buffer fluid in a heat exchanger with a discharge stream from a compressor in the NGL fractionation plant;
- discharging the buffer fluid from the heat exchanger via a collection header conduit to a Goswami cycle system comprising a power turbine;
- and
- generating power and sub-ambient cooling with heat from the buffer fluid in the Goswami cycle system.
A method of heat recovery from a Natural Gas Liquid (NGL) fractionation plant for generating power and sub-ambient cooling, the method comprising:
- heating a buffer fluid in a heat exchanger with an outlet stream from a distillation column in a NGL fractionation plant, the distillation column comprising a de-butanizer distillation column, a de-pentanizer distillation column, an Amine-Di-Iso-Propanol (ADIP) regenerator distillation column, a natural gas (NG) decolorizer distillation column, or a Reid Vapor Pressure (RVP) distillation column;
- discharging the buffer fluid from the heat exchanger via a collection header conduit to a sub-system comprising a power turbine;
- and
- generating power and sub-ambient cooling via the sub-system with heat from the buffer fluid.
