AP1341A

Deep conversion combining the demetallization and the conversion of crudes, residues or heavy oils into light liquids with pure or impure oxygenated compounds.

Abstract

A process for the conversion of hydrocarbons that are solid or have a high boiling temperature and may be laden with metals, sulfur or sediments, into liquids (gasolines, gas oil, fuels) with the help of a jet of gas properly superheated betwwen 600 and 800c. The process comprises preheating a feed (5) in a heater (8) to a temperature below the selected temperature of a reactor (10). This feed injected by injectors (4) into the empty reactor (10) (i.e. without catalyst.) the feed is treated with a jet of gas or superheated steam from superheater (2) to activate the feed. The activated products in the feed are well allowed to stabilize at the selected temperature and at a selected pressure in the reactor and are then run through a series of extractors (13) to separate heavy and light hydrocarbons and to demetallize the feed. Useful products appearing in the form of water/hydrocarbon emulsions are generally demulsified in emulsion breaker (16) to form water laden with different impurities. The light phase containing the final hydrocarbons is heated in heater (98) and is separated into cuts of conventional products, according to the demand for fefining by an extractor (18) similar to (13).
