Facility for on-site production of a medical gas with a plurality of storage units in series and a purging line

摘要

The facility (100) has a gas compressor unit (31) supplying to-be-purified compressed gas to a gas purification unit (50). A main gas line (10) fluidly connects the gas purification unit to a user site (30). A purified gas storage unit (A) is arranged in the main gas line. The main gas line comprises another purified gas storage unit (B) that is arranged in series downstream of the former purified gas storage unit. An exhaust line (11) is fluidly connected to the main gas line to exhaust the gas to atmosphere (12).
