Synthesis gas system operating method for producing e.g. additive gas product, involves conveying compressed gas flow by adsorber filled with adsorbent before introduction into gas system, where flow is free from carried impurities

摘要

The method involves compressing, returning and introducing a gas flow withdrawn from a cryogenic gas decomposition device i.e. gas decomposer (K), into a synthesis gas system in an operating mode i.e. A-mode. A contaminating compressor (V3) is used for compressing the gas flow. The compressed gas flow is conveyed by an adsorber (S), filled with an adsorbent comprising activated charcoal, before introduction into the system, where the compressed flow is free from carried impurities. The adsorbent is loaded during the mode and regenerated or supplied after end of the mode. An independent claim is also included for a device for operating a synthesis gas system having cryogenic gas decomposition device and a contaminating compressor in an operating mode deviating from a normal operating mode.
