Certain aspects of natural gas liquid fractionation plant waste heat conversion to simultaneous power and potable water using Kalina Cycle and modified multi-effect-distillation system can be implemented as a system. 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 is 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. The first sub-system is 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 is thermally coupled to the waste heat recovery heat exchanger.

A device for evaporating a liquid such as liquid fuel. The device comprises: a shell; means for supplying heat to the shell; a porous wick located in the shell so that there is a gap between an outer surface side of the porous wick and an inner surface of the shell; means for supplying liquid to the porous wick; and an outlet in the shell for vapour produced in the gap by the application of heat from the shell to the liquid in the wick.

A process for reducing pressure of a vapor stream used for reducing a temperature or pressure in a reactor. A pressure of a vapor stream is reduced with a turbine to provide a lower pressure vapor stream. The vapor stream rotates a turbine wheel within the turbine. The turbine wheel is configured to transmit rotational movement to an electrical generator. Thus, electricity is generated with the turbine. The lower pressure vapor stream is injected into a reactor and reduces a temperature in the reactor or reduces a partial pressure of a hydrocarbon vapor in the reactor.

A coil assembly for a combustion chamber includes a first tube arranged into a plurality of inner coils and a second tube arranged into a plurality of outer coils that surround the plurality of inner coils. Each inner coil contacts adjacent inner coils. The plurality of outer coils are separated from adjacent outer coils by a plurality of spaces. The first and second tubes are configured to transport a heat transfer fluid (HTF). The plurality of inner coils are separated from the plurality of outer coils by a gap. The coil assembly also includes a cylindrical shroud surrounding at least a portion of the coil assembly. The cylindrical shroud has a length that is less than a length of the coil assembly.
