The present invention describes a type of radial bed reactor which can allow a small quantity of catalyst to be used. Application to a regenerative reforming process reactor.

Radial bed reactor allowing the use of a small quantity of catalyst

The gaseous effluent is contacted with an aqueous solution comprising at least one amine and at least one amine degradation inhibiting compound. A stainless steel withstanding corrosion upon contact with the amine degradation inhibiting compound is first selected. Equipments whose surfaces in contact with the aqueous solution are made from this stainless steel are used.

The carbon dioxide contained in combustion fumes is absorbed by an aqueous amine solution in section B. The decarbonated fumes are then washed with water in wash section B. In order to prevent the discharge of amine degradation products with the decarbonated fumes, operation of the method is monitored and a fumes acid wash section U is used when required by the operating conditions of the carbon dioxide capture method.

The invention relates to a method for treating a natural gas, saturated or not with water, containing essentially hydrocarbons, a substantial amount of hydrogen sulfide and possibly carbon dioxide. The method of the invention comprises a condensation stage intended to condense a major part of the water, a distillation stage wherein a gaseous effluent depleted in hydrogen sulfide and substantially free of water is recovered, and a contacting stage wherein the gaseous effluent from the previous stage is contacted with a solvent so as to obtain a treated gas substantially free of hydrogen sulfide and possibly of carbon dioxide.

Sour natural gas treating method

The natural gas is successively contacted in column CA with a relatively methanol-rich solvent flowing in through linethen with a relatively poor solvent flowing in through lineThe acid gas-containing solvent recovered through lineat the bottom of column CA is expanded through valves Vand Vto release acid gases through lineA fraction of the expanded solvent is distilled in column CR. The regenerated solvent obtained at the bottom of column CR is sent to the top of column CA through lineA second fraction of the expanded solvent is mixed with a solvent drawn off from column CR at an intermediate point between the bottom and the top of this column. This mixture of solvents is sent through lineinto column CA.

Natural gas deacidizing method

A process for pretreating a very acid natural gas containing a substantial amount of hydrogen sulfide (H S), possibly combined with carbon dioxide (CO ), includes at least a stage wherein the initial natural gas is contacted in a distillation column with a liquid condensate itself resulting from cooling of the gaseous fraction obtained during the contacting stage. This solution allows to eventually recover at a lower cost a gas enriched in methane, depleted in hydrogen sulfide and freed from substantially all of the water it contains, and a liquid phase containing most of the hydrogen sulfide, substantially all of the water and depleted in hydrocarbon. Control of the thermodynamic conditions during the stages that characterize the process, according to the water content of the gas during treatment, allows progressive exhaustion of the water contained in the gas while preventing hydrates formation.

Process for pretreating a natural gas containing acid gases

In a process for treating a gas containing acid gases, the gas is contacted with a methanol-containing aqueous phase and is then contacted in an absorption column with a mixture of solvents including mehtanol, water and a solvent heavier than methanol. Then, the mixture of solvents is at least partly regenerated through pressure reduction and/or heating. The treated gas is cooled by producing at least a methanol-containing aqueous phase that is at least partly recycled. The mixture of solvents flowing out at the bottom of the absorption column is cooled, then re-introduced at a higher level of the absorption column so as to control the temperature in the absorption column.
