Problems solved by technology

However, due to the high temperature in the combustion chamber, especially at the tube tip, refractory materials have proven unsatisfactory from a long-term point of view. Therefore, in order to meet the above-mentioned requirements, the life of the oxygen feed pipe in the prior art equipment is still Short-lived

Embodiment Construction

[0026] refer to figure 1 , numeral 1 generally designates a secondary reformer of this type comprising a substantially cylindrical housing 2, in which is placed a catalytic bed 3 carrying out a secondary reaction, such as a steam reforming reaction, to produce synthesis gas.

[0027] At the top end of the casing 2 , generally frusto-conical, a combustion chamber 4 is defined for burning hydrocarbons, and at the lower end of the casing 2 , a compartment 5 is defined for collecting the synthesis gas produced in the catalytic bed 3 . The combustion chamber 4 and the compartment 5 are in fluid communication with said catalytic bed 3 .

[0028] Above the conical portion delimiting the combustion chamber 4, the casing 2 ends with an upper cylindrical appendage 2a of smaller diameter, which is the casing of the vertical duct 7 feeding reformed gases (hydrocarbons) to the combustion chamber 4 . Inside the conduit 7, a vertical tubular oxygen feed pipe 8 is installed, coaxial with th...

Abstract

A secondary renormalization equipment for burning a portion of renormalized gas with oxygen which comprises a catalyzing bed, firing chambers are arranged on the catalyzing bed in fluid connection, and a tool for feeding the gas flow containing oxygen and part of the renormalized gas into the combustion chambers.

Description

technical field [0001] The present invention relates to a device suitable for secondary reforming reactions. [0002] In particular, the present invention relates to a secondary reforming reaction plant for the production of a gas mixture comprising hydrogen and carbon monoxide, such as ammonia or methanol. [0003] More specifically, the secondary reformer according to the present invention is specially designed for the combustion of partially reformed gas with oxygen, comprising: [0004] - catalytic bed; [0005] - a combustor above and in fluid communication with said catalytic bed; [0006] - Means for separately feeding a gas stream comprising oxygen and a gas stream comprising partially reformed gas into said combustion chamber. [0007] In the field of secondary reforming reactions, this equipment is also called secondary reforming furnace or autothermal reforming furnace. [0008] In the following description and appended claims, the term "oxygen-comprising gas st...
