process the recovered gaseous constituents, a new 2000-bbl- per-day catalytic polymeriza tion unit was included as a part of the refinery expansion. Alleviation unit capacity for rhe production of the chief constituent of aviation gaso line from recovered gases was increased by 50 percent. In addition to these changes in basic processing and the new units involved, another major change involved re vamping the combination units to increase their crude More than 100 EUiott steam turbines ranging in sizefrom 2 hp to 600 hp are on thejob at Richfield Oil Corporation's new Watson refinery driving process and water pumps, also Jans and compressors. charging capacity by a total of 20.000 bbl per day. With the construction of any new processing units or redesign and modernization of existing units, a great deal of new and expanded Steel mill compressors auxiliary services are required. Rich field's recent refinery expansion pro gram required large expenditures for these added auxiliary services. In addition to utilities, field piping, storage and related items, new shops, and a warehouse were provided to service and maintain the facilities. EUiott steam turbines in sizes from 2 hp to 600 hp drive all sorts of pumps, tans, and compressors around the Watson refinery. A typical line of these turbines is illustrated. Turbines in the plant operate at three steam pressures. Some take steam at 600 The installation below shows two Elliott 800-hp, 180-rpm synchronous motors driving Ingersoll-Rand duplex air compressors in the Indiana Harbor Works of The Youngstown Sheet & Tube Company at East Chicago, Indiana. The two air compressors supply the general air requirements for a new cold-reduced sheet mill which cold-rolls sheet steel at the rate of 40,000 tons per month. The compressors also may supply emergency air supply to a nearby tin mill. With both compressors operating, the complete requirements of both tin mill and sheet mill may be supplied, the tonnage capacity of both plants being 120,000 tons per month. Air requirements include air cylinders, air hoists, air lifts, also emergency cooling and cleaning of equipment.
