A process of partial oxidation is performed in a reactor which includes a reaction chamber and a burner assembly, wherein: the burner assembly has a single oxidant nozzle located within an fuel channel, said oxidant nozzle comprises a nozzle pipe and a nozzle outlet, the nozzle pipe and the fuel channel are arranged to produce a diffusion flame, the nozzle outlet has a shape with two or more elongate lobes projecting from a center of the nozzle pipe.

Reactor and process for partial oxidation

A burner () for the production of synthesis gas, configured to feed a reactant stream and an oxidant stream into a reaction chamber, the burner comprising at least one cooled component (), wherein said cooled component comprises channels () to convey a cooling medium, a cooling medium header () and a cooling medium collector (), wherein said channels, said cooling medium header and said cooling medium collector are integrally formed within said cooled component of the burner.

Burner for synthesis gas with improved cooling

A burner system () for the combustion of a hydrocarbon feedstock with an oxidant, comprising at least one burner () and a cooling circuit (), where in: the burner system () comprises a fuel side () and an oxidant side (); the burner () comprises a cooling chamber () connected to said cooling circuit(); said cooling circuit () comprises a reservoir tank() for said cooling fluid and a circulation pump(); said system () comprises pressure equalizing line () arranged to establish a fluid communication between the inside of said reservoir tank () and at least one of said fuel side and oxidant side.

Burner for the production of synthesis gas and related cooling circuit

A process and related reactor () for oxidation of a hydrocarbon feedstock are disclosed, the reactor () comprising a vessel () and a neck () with an axial burner () and a tangential gas inlet (), wherein the neck () has a swirling chamber () located below said burner () and connected to said gas inlet (), to produce a gas vortex (V) which optimizes the mixing between the gas stream (G) and the oxidizer in said neck (). Preferably the swirling chamber () has an internal surface () with a log-spiral profile.

Process and a reactor for oxidation of a hydrocarbon

A method for revamping a secondary reformer (), the reformer comprising an internal gas riser pipe () for routing a process gas from a bottom gas inlet to a combustion chamber () located above a catalytic zone (), and a distributor () for introduction of an oxidation agent such as process air into the combustion chamber. The original distributor of the oxidation agent is discontinued, the gas riser pipe is shortened (') and the outlet end of the shortened gas riser pipe is arranged to deliver a gas flow directed upwards. A new burner () is installed on top of the reformer, the new burner being arranged to deliver an oxidation agent such as process air with a downward flow, thus obtaining a counterflow mixing zone () and formation of a diffusion flame above the outlet end of the gas riser pipe.

Method for revamping a secondary reformer

A catalytic secondary reforming process, for the production of synthesis gas, comprises the successive steps of: feeding a first gas flow comprising hydrocarbons and a second gas flow comprising oxygen into a reforming reactor, at least one of such gas flows being fed into the reactor in a predetermined feed direction substantially parallel, preferably coaxial, to a longitudinal axis of the reactor, mixing the gas flows in the reactor, with substantially simultaneous oxidation of the hydrocarbons of the first gas flow by the oxygen of the second flow.

Catalytic secondary reforming process and reactor for said process

Plate type heat exchanger () for a isothermal chemical reactor (), of the type comprising a substantially box-shaped flattened body (), defining an internal chamber () and equipped with an inlet connection () and an outlet connection () for a first flow of a heat exchanger operative fluid into and from said chamber (), at least one supplying-distributing device () of a second fluid flow, associated with said body () and in fluid communication with the internal chamber () thereof, in order to regulate the temperature of said operative fluid, said at least one supplying-distributing device () being supported inside said internal chamber () and in fluid communication therewith.
