The gas of flare easier block the cylinder of compressor when the mixed components of gases transfer in the flare gases recycle system of YPC Logistic Department, and the result caused that the system can not be run smoothly with higher capacity and the running period shorten, and also higher maintenance cost needed, so after researching and investigation together with Nanjing Industry University, we determined add a device that online cleaning the system with the water of missing salt after did an experiment by adjusting the temperature of polymerization after sampled and analyzed the components of the gases and the blocked substance, and reduce the temperature of flare cylinder pipe, and flush the blocked materials in the compressor to ensure the machine running smoothly with a longer periods and higher charges ultimately.
