PROCESS AND PLANT FOR REHEATING PURIFIED GAS FOLLOWING THE PURIFICATION BY WET PROCESS OF RAW GAS

摘要

purified gases cooled (32) after being subjected to purification by wet are reheated by régénateur heat exchange (26) with warmer raw gas (24) not further purified, a partial flow of Heated already previously purified gas being mixed (42) to the flow of gas purified before crossing the regenerator heat exchange. Before the regenerative reheating of the gases purified using the thermal energy derived raw gas, the partial flow of the purified gas is separated (36) of the total flow of purified gas before wet he sees its pressure s' increase (44) and is heated in part, separated from the main flow of purified gas in the regenerator heat exchanger (26) with the raw gas.
