Sectionalized box style steam methane reformer

A box style steam methane reformer, comprising:

• a) plural sections, each section comprising:
• i) A top wall, a bottom wall, and side walls forming an interior cavity, the respective section having open ends that communicate with the interior cavity;
• ii) At least one feedstock supply pipe located along the top wall outside of the interior cavity, the feedstock supply pipe having feedstock supply pipe ends;
• iii) At least one fuel supply pipe located along the top wall outside of the interior cavity, the fuel supply pipe having fuel supply pipe ends;
• iv) At least one syngas collection pipe located outside of the bottom wall, the syngas collection pipe having syngas collection pipe ends;
• v) At least one flue gas collection duct located outside of the bottom wall, the flue gas collection duct having flue gas collection duct ends;
• vi) Reactor tubes located in the interior cavity and extending from the bottom wall to the top wall, the reactor tubes having a top end connected to the feedstock supply pipe and a bottom end connected to the syngas collection pipe;
• vii) Burners located in the interior cavity adjacent to the top wall and being connected to the fuel supply pipe, the burners providing radiant heating of the reactor tubes;
• b) One of the ends of a first section coupled to one of the ends of a second section so as to form a continuous interior cavity between the first and second sections, with one of the feedstock supply pipe ends of the first section being coupled to the one of the feedstock supply pipe ends of the second section, one of the fuel supply pipe ends of the first section being coupled to the one of the fuel supply pipe ends of the second section, one of the syngas collection pipe ends of the first section being coupled to the one of the syngas collection pipe ends of the second section, one of the flue gas collection duct ends of the first section being coupled to one of the flue gas collection duct ends of the second section.
