Electrolysis drain system

Abstract

The present disclosure relates to an electrolysis apparatus drain (2) system comprising a storage vessel (16) configured to receive an extracted fluid and a pressure regulation valve (28) fluidly connected to the storage vessel (16) and provided downstream of the storage vessel (16). A drain valve (30) is configured to control flow of the extracted fluid from the storage vessel (16) and provided downstream of the pressure regulation valve (28). An upstream side of the pressure regulation valve (28) is provided at the same pressure environment as the storage vessel (16) and a downstream side of the pressure regulation valve (28) provides a predetermined pressure at the drain valve (30).
