摘要: The present invention is a process for removing waxy haze from and improving the filterability of base stocks including heavy mineral oil base stocks, gas-to-liquids (GTL) and hydrodewaxed or hydroisomerized waxy feed basestocks by filtering the waxy haze causing particles out of the base stock employing a filter characterized by a high surface area of pores accessible to the haze wax particles which have particles dimensions of no more than about 5 microns.

摘要: A hybrid filter system and a method for filtering process fluid utilizing a backwash containment vessel. Tube sheet assemblies designed to hold disposable or backwashable filter elements are utilized to secure either type of filter elements in the backwash containment vessel. The tube sheet assemblies are removably mounted in the backwash containment vessel, and may be easily swapped for a given filtering application. The hybrid filter system utilizes a backwash containment vessel in conjunction with either disposable filter elements or backwashable filter elements depending upon process flow parameters.
