Title:
METHOD FOR USING RECOMPRESSED VAPOR AND PLANT
Document Type and Number:
WIPO Patent Application WO/2018/079370
Kind Code:
A1
Abstract:
The present invention is a method for using recompressed vapor comprising a main step for generating process vapor that includes a condensable gas component and recovering a condensate of the condensable gas component in the process vapor generated, a recompression step 5 for adiabatic compression of at least part of the process vapor by a compressor, increasing temperature, and obtaining recompressed vapor, a heat exchange step 7 using the recompressed vapor as a heat source, and a circulation step 9 for returning the non-condensed components of the recompressed vapor supplied to the heat exchange step 7 to the main step, wherein the method includes at least a holding step 8 for retaining the condensate condensed in the heat exchange step 7 and holding pressure of a back-pressure space downstream of the compressor. With this method, process vapor (recompressed vapor) that has been heated by adiabatic compression can be used efficiently as a heat source.
