Pipework access in air separation cold boxes

Traditional LNG receiving stations use seawater open-frame vaporisers or submerged combustion vaporisers to vaporise LNG, which not only wastes valuable cold energy but also produces localised low temperature pollution of the nearby sea. The air separation temperature range is between -190C - 150C and the LNG vaporisation temperature is -162C, which matches the liquid air separation plant temperature range. The use of LNG's high quality low temperature cold energy for liquid air separation plant...

 The purpose of the blowing is to clean out the residual slag, aluminium chips and other debris from the piping and vessels. the air source for blowing is provided by the turbine compressor, and the air cooling tower must be activated. 3. blowing principle, first outside the tower, after the tower, blowing brush to be one after another, in the blowing with the air pressure: low pressure system. Should be maintained at 40 a 50kpa high pressure system: should be maintained at 250 ~ 400k...
