Method\ Predehydration process of high pour-point is performed by using effective chemical predehydrating. Purpose\ To solve the problems about energy loss in purification of high pour-point oil and excess loss of additives. Result\ Over 80% of water is predehydrated with some of heaters being out of work, after chemical predehydration is performed. Conclusion\ The process considerably reduces the fuel and chemical additives needed in the purification of crude oil and production cost so that annual economic benefit reaches RMB$ 292×10\+4.
