Abstract:

The invention relates to a process for preparing lube oil basestocks from lube oil boiling range feeds. More particularly, the present invention is directed toward a process wherein a wax containing feed is solvent dewaxed to produce at least a partially dewaxed lube oil boiling range stream, which is hydrodewaxed to produce a first lube basestock. The first lube basestock is added to an independently selected second lube basestock and additives to make a lubricating oil.

International Classification:

C10G 45/12

US Classification:

208 89

Abstract:

A diesel fuel product with beneficial cold flow properties can be produced. A suitable feedstock for forming a diesel boiling range product can be hydrotreated to have a sulfur content of at least about 100 wppm and then dewaxed. This two stage process can allow for production of an arctic or winter diesel without use of high pressures. Optionally, a divided wall column fractionator can be used to allow a single separation stage to handle the effluent from both the hydroprocessing and the dewaxing stages.

International Classification:

C01B 25/232
B01D 19/04

Abstract:

A wet process phosphoric acid production method comprises digesting phosphate-containing ore in a slurry comprising sulfuric acid, whereby phosphoric acid and calcium sulfate crystals are formed; and separating the phosphoric acid from the calcium sulfate crystals; wherein a defoamer and a poly(carboxylic acid), or salt thereof, having a weight-average molecular weight of less than 1,000,000 grams per mole (g/mol), are added to the slurry. The poly(carboxylic acid) can be a poly(acrylic acid), or salt thereof, and the defoamer can be a dialkyl sulfosuccinate salt and an aliphatic alcohol or a fatty acid ester. The method enhances separation of phosphoric acid from calcium sulfate crystals in wet process phosphoric acid production by any one of increasing the volume average particle size of the calcium sulfate crystals, increasing filtration rate, and reducing foam formation.
