In a reactor for partial oxidation of feedstock employing a hot oxygen stream that is generated by a suitable burner, the same burner that generates and provides the hot oxygen stream in full-scale partial oxidation operation can be employed in the starting-up of the partial oxidation reactor by suitable control of the characteristics of the feed to the burner, or of the pressures.

Startup methods for oxidation reactor

Disclosed are methods for accommodating changes in the conditions of partial oxidation of hydrocarbonaceous feedstock by changing characteristics of the hot oxygen used in the partial oxidation.

Methods of operational flexibility in partial oxidation

The present invention relates to a method of combusting a fuel gas with a stoichiometric or near stoichiometric amount of molecular oxygen in the presence of a controlled amount of a diluent to enhance the extent of combustion reactions in high heat transfer environment. The energy released is utilized to heat a fluid by direct contact with the flame. The diluent can be different from the fluid to be heated with respect to composition, temperature or pressure. The diluent can be same as or derived from the fluid to be heated.

Method for enhancing combustion reactions in high heat transfer environments

A burner comprises a central passageway and outlets for fuel and for stabilizing oxidant arranged peripherally around the central passageway, and comprises outlets within the burner through which biasing gas, such as gas comprising oxygen, can be injected to enable control of the direction of the flame that is generated by combustion of the fuel and the oxidant at the face of the burner.

Fluidic burner with heat stability

In a burner in which fuel and gaseous oxidant are fed into the burner and combusted to produce a flame that extends out of an end of the burner, the noise produced by the burner is lessened by incorporating into the burner a baffle composed of a metal plate having a certain distribution of holes through the plate and a layer of metal filaments, and optionally a second metal plate.

Burner with baffle

Soot formation in the partial oxidation of carbonaceous feed is controlled by controlling the momentum of the oxidant stream relative to the momentum of the carbonaceous feed stream.
