James G. Speight, in The Refinery of the Future, 2011. 2.4.7 Solvent Dewaxing. Solvent dewaxing processes are designed to remove wax from lubricating oils to give the product good fluidity characteristics at low temperatures (e.g., low pour points), rather than being used to treat the whole crude oil (Speight, 2007).The mechanism of solvent dewaxing involves either the separation of wax as a ...

THE DEWAXING PROCESS Definition & Overview Dewaxing: Separation of waxes, esters of long chain fatty acids and long chain primary alcohols present in mainly sunflower and maize oil. Winterisation: Separation of saturated triacylglycerols from e.g. cottonseed oil and partly hydrogenated oils. Some oils are dewaxed before packing so as to remove waxes, which are dissolved in the oil.

A process for treating cooking oil or fat which comprises contacting cooking oil or fat with magnesium silicate and at least one alkali material, such as, for example, calcium hydroxide. The magnesium silicate and at least one alkali material are present in amounts effective to reduce the content of free fatty acids in the oil or fat and permit reuse of the oil or fat for cooking.

However, so far as we are aware, the prior efforts have failed to solve this oil problem. The conventional dewaxing processes now in general commercial use produce a rather haphazard mixture of large and small wax crystals which reduce the rate of filtration, while trapping excessive quantities of oil solution in the mass of nonuniform crystals

Conventional Oil & Gas. Conventional Oil and Gas is simply known as the traditional way to drill for raw natural gas, crude oil, and petroleum. So what do I mean by traditional? After a well is drilled, oil and gas is extracted by the natural pressure from the wells and pumping operations. Over time, the well may decrease in production. At this
