A vapor recovery unit accomplishes the separation of the products pro duced in the car-cracking unit. Feed to the unit is the unstable g; and gas from the overhead nc lator of the main fractionator cat-cracking unit. The end pn of the separation performed i unit arc debutanized gasolini tanes, propanes, and dry gas. Wet gas feed is compressed (I wet gas compressor) and rccont with both the bottoms from the absorber and the vapors fron stripper. Vapors from the conta drum are fed to the absorber t which utilizes unstable gasolit the absorption medium. Steam requirements are met iv plant consisting of three boilers, with a 75,000 lb per hr capa Many Elliott steam turbines c various pumps around the refir and Elliott-Lagonda tube clea are used on stills and heat e.xch< equipment. The complete plant was enginet and constructed by Lummus C pany of New York in 18 months.' design is such that the plan: operated with fewer than 200 i ployces whereas plants of this k sometimes require 350 employees Suntide Refining Company is affiliate of Sunrav Oil Corporati Tulsa.

Tn the new factor) Elliott two-stage steam jet ejectors, one n! which is illustrated, serve the vacuum pans which work oil a .steam pressure up to 15 psig. this steam l ing a mixture of vapors from the pre-evaporator and exhaust from the mill turbines. The evaporator and each pan are individually equip ptxl with a counter-current condenser served by an Elliott two-stage steam jet ejector. Operators like ejectors belter than vacuum pumps, repairs and maintenance have been practically eliminated, and with ejectors on individual units, starting and stopping of other units cause no fluctuation trouble.
