Keystone provided multi-discipline engineering and design services for a major project to install a $125MM new Alkylation Unit. The design basis of the new Alkylation Unit involved utilizing an existing decommissioned unit at another site. Nine pieces of equipment at that site were refurbished and reused for this project, including a refrigerant compressor, contactors, and six pressure vessels. One reboiler/heater, three towers, ten tanks, 11 heat exchangers, 21 drums, and 49 pumps were specified, purchased new, and installed. The additional connected electrical load required an addition of electrical substation and DCS control expansion including 800 new instruments. Additionally, the project implemented new cooling towers and instrument air compressors to expand existing facility utility infrastructure to support the process unit installation. An existing LPG Truck Loading Rack was demolished to create room for unit installation and a new LPG truck loading rack was engineered to support facility with safety interlock updates.
