Gas separation system with lock arrangement for the supply and / or discharge of a granular conveying medium into a process chamber

Abstract

The present invention relates to a sluice arrangement for supplying and / or discharging a granular conveying medium into a process chamber of a gas separation plant, comprising a pipeline section, a shut-off device configured to close or open an opening in the pipeline section in a gas-tight manner, and a shading device with a sleeve, wherein the sleeve of the shading device is configured to be arranged inside the opening in order to seal the shut-off device against the granular conveying medium in the open state.

Claims
