Method for the purification of the process condensate from synthesis gases and hydrogen plant

摘要

The object of the invention is a method for the purification of the process condensate from synthesis gases or hydrogen plant.P PThe process condensate is purified from contaminations dissolved in it by stripping it with process steam before it is used in the chemical process of the raw material conversion into hydrogen or synthesis gas at the pressure that is equal or higher than the pressure of this conversion process. The total steam containing volatile products of the process condensate degassing is recycled to the gas generation process and the process condensate is eventual transported to the water treatment station before using it as boiler feed water.
