Cracked gas compressor function
WebThe cracked gas from the furnace must be cooled down as fast as possible to avoid over-cracking. This happens in three steps: the selective linear exchanger (SLE), the quench oil tower and the quench water tower. ... The following considers a three-phase separator as a knockout drum for a five-stage cracker gas compressor, to provide adequate ... WebThe cracked gas compressor is a multi-section centrifugal compressor, with 4 or 5 stages of compression required to bring the cracked gas pressure up to the desired value of approx. 40 bara. The cracked gas compressor is usually driven by an extraction type steam turbine, using high pressure live steam and extracting steam to the plant’s medium
