Abstract:

An exhaust steam stream having an absolute pressure from 200 kPa to 1,050 kPa and shaft power are produced from an extraction turbine and/or a back-pressure turbine. The exhaust steam stream can be supplied to an amine regenerator of an amine COseparation process. The shaft power can be utilized to drive equipment in a hydrocarbon processing plant such as an olefins production plant.

Abstract:

A method and system are disclosed for managing hydrate formation in a process that converts a hydrocarbon stream into Cunsaturates, such as ethylene and/or acetylenes. The method includes adding a hydrate inhibitor to a hydrocarbon stream to lower the hydrate formation point of the mixture stream from an initial hydrate formation point (H) of the hydrocarbon stream to a depressed hydrate formation point (H) of the mixture stream. Then, the mixture stream is depressurized to adiabatically cool the stream to a temperature (T), wherein the H
