| Abstract: | Technological revision has been made to the online gas chromatograph analyzer that was used to analyze the hydrogen content of propylene.Only one ten-way valve was used to accomplish the analysis and inverse blow process that were carried out by the manufacturer with two ten-way valves.At the same time,double flow-way toggle was realized on the two analyzers.Not only large amount of foreign exchanges was saved,but also the two analyzers became ready standby for each other.And this supplies a powerful assurance for the safe and steady operation of the units. |
