US 7,967,954 B2 · 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 between 600 and 800° C. The process comprises preheating a feed 5 in a heater 8 to a temperature below the selected temperature of a reactor 10. This feed is 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 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 refining by an extractor 18 similar to 13.

Dependent claims

A system for cracking hydrocarbons:

an injector having a plurality of passageways with a hydrocarbon flow therein, and a gas passageway having a gas flow therein, said plurality of the passageways and said gas passageway being configured with respect to one another such that said gas flow impinges at a location in said hydrocarbon flow in a manner such that said gas flow adds kinetic energy into the hydrocarbons at said impinged location;
separately adjustable at least two heating sources, at least one heating source being associated with said plurality of the passageways and another heating source being associated with said gas passageway, configured to set a temperature of between about 415° C. and 500° C. in said plurality of the passageway and a temperature of between about 600° C. and 800° C. in said gas passageway;
an empty catalyst-free reactor operatively connected to said injector such that said reactor is configured with respect to said plurality of passageways of said injector so as to collect hydrocarbons impinged upon with said gas flow;
and
one or more extractors operatively connected to said empty catalyst-free reactor.
