English term or phrase:deisobutanizer overhead
Este vorba despre construirea la Petrobrazi a unei instalaţii de alchilare cu catalizator acid sulfuric.
The high purity make-up isobutane stream is comprised of an Isobutane stream from Petrobrazi and an Isobutane stream from Arpechim. The Isobutane feed is combined within the battery limit and received in the Feed Surge Drum (F-121) and pumped by P-131A/B. Two internal streams supply isobutane to the Reaction Zone to provide the required isobutane to olefin ratio. These streams are the recycle isobutane from the deisobutanizer overhead and the refrigerant recycle from the flash drum.
