Fractionation tower heating, cooling, liquid accumulation and purification in one go, simple and fast operation. Using aluminium plate fin heat exchanger, aluminium convection sieve tower, the whole fractionation tower equipment pipeline using argon arc welding, cold box tower and the main pipeline, using high-strength aluminium alloy material or stainless steel material, in order to increase the strength, reduce the torsional damage of the pipeline. Cold box equipment bracket, pipeline and valve bracket should be used stainless steel or aluminium alloy material. The cold box is insulated with pearlescent sand and slag wool to ensure minimum cold loss. The structure of the cold box ensures the overall strength and requirements of earthquake and wind resistance to ensure the load-bearing capacity of the cold box; the cold box is equipped with sealed gas protection and safety devices during operation; the main equipment in the cold box is set up with electrostatic grounding; the cold valve and pipe connections in the cold box are all welded, avoiding the use of flange connections.
