Process, reactor and burner for the gasification of a hydrocarbon fuel. The burner comprises coaxial channels for the separate supply of an oxidizer gas, a hydrocarbon fuel and a moderator gas. A coaxial channel with the smallest width is bordered by a separating wall with at least one gas exchange. The gas exchange passage can for example be formed by a retracted end of the separating wall and/or by openings in the separating wall.

Burner, reactor and process for gasification of a hydrocarbon feed

A process to prepare a synthesis gas mixture comprising hydrogen and carbon monoxide from a liquid hydrocarbon feedstock containing between 0.1 and 4 wt % ash comprises performing a partial oxidation on a hydrocarbon feed using a multi-orifice burner provided with an arrangement of separate co-annular passages, wherein the hydrocarbon flows through a passage of the burner, an oxidizer gas flows through a separate passage of the burner and wherein the passage for hydrocarbon feed and the passage for oxidizer gas are separated by a passage through which a moderator gas flows and wherein the exit velocity of the moderator gas is greater than the exit velocity of the oxidizer gas.

Process to prepare a mixture of hydrogen and carbon monoxide from a liquid hydrocarbon feedstock containing a certain amount of ash

Gasification reactor and process for the production of synthesis gas by partial combustion of a carbonaceous feed. The reactor comprises a reactor chamber with one or more burners and at least one oil lance extending into the reactor chamber. The oil lances can for instance be located at a level 1.5 meters or less below or above the burners.

Gasification reactor

A process to prepare a sweet crude from an ash containing and heavy fraction of a tar sand oil comprising supplying an atmospheric distillation bottoms of a tar sands originated feed to a vacuum distillation to obtain a vacuum gas oil and a vacuum bottoms and contacting the vacuum gas oil with hydrogen to obtain a sweet synthetic crude. The vacuum bottoms obtained are separated into an asphalt fraction comprising between 0.1 and 4 wt % ash and a de-asphalted oil and the asphalt fraction is fed to a burner of a gasification reactor to obtain a mixture of hydrogen and carbon monoxide on which a water gas shift reaction is performed. Hydrogen sulphide and carbon dioxide are separated from the shifted gas in an acid removal unit thereby obtaining crude hydrogen which is purified and used to obtain the sweet synthetic crude. The asphalt fraction is provided to the burner in a liquid state and wherein in case the separation step fails to provide sufficient feed for the gasification reactor, vacuum bottoms from the first step are fed to the burner in a liquid state.

Process to prepare a sweet crude

The invention is directed to a process to prepare a mixture of hydrogen and carbon monoxide by performing a partial oxidation on a hydrocarbon feed using a multi-orifice burner provided with an arrangement of separate passages, wherein the hydrocarbon flows through a passage of the burner, an oxidiser gas flows through a separate passage of the burner and wherein the passage for hydrocarbon feed and the passage for oxidiser gas are separated by a passage through which a moderator gas flows and wherein the exit velocity of the moderator gas is greater than the exit velocity of the oxidiser gas.
