Process and apparatus for steam reforming, and method for starting the apparatus for operation contu00ecnua ".Recycling a portion of the effluent autotu00e9rmico reformer in the current supply of steam to hydrocarbon with an ejection end compressor is disclosed.Using the mixture of supply pru00e9aquecida as motive fluid. The relations of the synthesis gas recycled to the driving fluid are 0.2 - 1.0, selected to optimize the overall configuration.The recycled hydrogen and steam introduced in supply and raises the temperature of supply, to operate the reformer in a soot free scheme.Is there any pressure drop between the mixture of current gross natural gas supply and the supply of the reformer, which requires that the mixture of gross supply is supplied to a greater pressure.But this is offset by the lower pressure drop in the heat of the process and other equipment upstream and downstream, due to lower quantities of steam.The pre heater can have a lower supply work, and the upstream and downstream equipment can be reduced in size.While the size of the reformer autotu00e9rmico stay around the same in comparison to the size required for operation without effluent recycle.
