Fractionator system (cold box)

The heating, cooling, liquid accumulation and purification of the fractionation tower can be completed in one go, and the operation is simple, quick and simple. Adopt aluminum plate-fin heat exchanger, aluminum convection sieve plate tower, the entire fractionation tower equipment pipeline adopts argon arc welding, the tower body and main pipeline in the cold box are made of high-strength aluminum alloy or stainless steel to increase the strength , Reduce the torsion damage of the pipeline. The equipment brackets, pipes and valve brackets in the cold box shall be made of stainless steel or aluminum alloy. The cold box is insulated with pearl sand and slag wool to ensure that the loss of cold capacity is minimized. The cold box structure guarantees the overall strength and requirements of seismic and wind resistance, and guarantees the load-bearing capacity of the cold box. When the cold box is running, it is equipped with airtight protection and safety devices. The main equipment in the cold box is equipped with electrostatic grounding. The cold valve and pipeline in the cold box All connections are welded, and flange connections are avoided.
