2020 REFINING PROCESSES HANDBOOK PROCESS CATEGORIES COMPANY INDEX LUBRICANTS AND WAXES Hydrofinishing/Hydrotreating Reactor Reactor feed heater Striper STM Vent gas to heater Application: A process to produce finished lube base oils and special oils. Description: Feedstock is fed together with make-up and recycle hydrogen over a fixed bed of catalyst at moderate temperature and pressure. The treated oil is separated from unreacted hydrogen, which is recycled. Very high yields of product are obtained. The lube oil hydrofinishing process operates at medium hydrogen pressure, moderate temperature and low hydrogen consumption. Operating pressures of hydrogen finishing processes range from 25 bar-80 bar. A higher pressure range affords greater flexibility with regard to base stock source and product qualities. Oil color and thermal stability depend on treating severity. Hydrogen consumption depends on feedstock and desired product quality. STM To fuel gas (H2Sabsorption) Makeup gas compressor Feeds: Solvent de-waxed lube stocks for lubricating oils ranging from spindle oil to machine oil and bright stock. Products: Finished lube oils (base grades or intermediate lube oils) and special oils with specified color, thermal and oxidation stability. Utilities: (Typical, Middle East crude; units per m³ of feed): Electricity 15 kWh MP steam 25 kg LP steam 30 kg Cooling water 20 m³ Installations: Numerous installations under thyssenkrupp license are in operation around the world.
