The invention relates to a method for decreasing the spread of the tube temperatures between tubes in a process involving the heating of at least one fluid in a furnace that comprises at least one radiation chamber with radiant walls, at least one essentially vertical row of tubes inside of which circulate the at least one fluid to be heated, and being equipped with burners that heat the tubes, where the method comprises the steps of: determining, for each of the tubes the skin temperature of the tube, selecting the 50% tubes having the lowest temperatures determined, the process being stopped, realizing on each tube selected an operation that decreases the flow of the fluid distributed to said tube while keeping the total flow rate of the fluid unchanged.

Method to homogenize the tube temperatures between tubes during processes involving heating of gas flowing in the tubes

An installation and process for producing hydrogen, which includes a purification unit for purifying a hydrogen-rich synthesis gas and for producing hydrogen and a waste gas, along with the additional equipment required in order to continue operation in the event of a purification unit shutdown.
