HYDROISOMERISATION METHOD Russian patent published in 2012 - IPC C10G45/58 C10G65/12 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to method (10) involving the creation of hydrocarbon raw material flow (14) with opacity temperature, flow loss point and cold filter plugging point (CFPP); extraction at least of some hydrocarbon raw material flow as raw material (14) for hydrotreatment; raw material (14) for hydrotreatment does not contain hydrocarbons from hydroisomerisation zone with continuous liquid phase; mixing of raw material (14) for hydrotreatment with hydrogen (16); at that, hydrogen is contained in the form available for constant flow rate in the hydroisomerisation zone with continuous liquid phase; direction of raw material (14) mixed with hydrogen for hydrotreatment to hydroisomerisation zone (12) with continuous liquid phase; and implementation of reaction of raw material (14) for hydrotreatment in hydroisomerisation zone (12) with continuous liquid phase using at least one hydroisomerisation catalyst under hydroisomerisation conditions under which outlet flow (18) having at least one of the following characteristics is formed: opacity temperature, flow loss point and CFPP value below the corresponding characteristics of hydrocarbon raw material flow (14).

EFFECT: improvement of characteristics of cold flow of hydrocarbon flows.
