HEAT INTEGRATION APPARATUS FOR DME FPSO

摘要

The present invention relates to a DME FPSO including a reforming system, which reduces the temperature of synthetic gas which flows into a synthetic gas cooler (20), by connecting a path for passing to a DME/MeOH recovery and purification system to the middle of a path of the synthetic gas progressing to the synthetic gas cooler (20) from a synthetic gas G/L separator (10) in the reforming system. Accordingly, the overall energy efficiency can be improved by heat integration between systems, by using the heat of the high temperature synthetic gas, instead of the intermediate pressure steam, in a process of generating the synthetic gas in the DME FPSO.
