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 method of cleaning hollow fiber membranes comprising directing a fluid into a hollow fiber filtration module (10) comprising a housing (12), a feed fluid inlet (14), a retentate outlet (16), a permeate outlet (18), and at least one hollow fiber membrane (20) disposed in the housing (12), wherein the hollow fiber membrane (20) has a bore (26), an inner surface (28), and an outer surface (30), providing a first pressure to the inner surface (28) of the hollow fiber membrane (20) through the retentate outlet (16) and passing the fluid along the bore (26) of at least one hollow fiber membrane (20) to provide a retentate and a permeate, increasing the first pressure, applying a second pressure to the outer surface (30) of the hollow fiber membrane (20) through the permeate outlet (18), and releasing the increased first pressure while maintaining or increasing the second pressure to pass permeate from the outer surface (30) to the inner surface (28) of the hollow fiber membrane (20), is disclosed.
摘要翻译：一种清洁中空纤维膜的方法，包括将流体引导到包括壳体（12），进料流体入口（14），滞留物出口（16），渗透物出口（18）的中空纤维过滤模块（10）设置在所述壳体（12）中的至少一个中空纤维膜（20），其中所述中空纤维膜（20）具有孔（26），内表面（28）和外表面（30），提供第一通过滞留物出口（16）向中空纤维膜（20）的内表面（28）施加压力并使流体沿着至少一个中空纤维膜（20）的孔（26）流动，以提供渗余物和渗透物增加第一压力，通过渗透物出口（18）向中空纤维膜（20）的外表面（30）施加第二压力，并释放增加的第一压力，同时保持或增加第二压力以使渗透物从到中空纤维膜（20）的内表面（28）的外表面（30）为di sclosed。
