The Production of Synthesis Gas by a Combination of Steam and Dry Reforming Using GHR

摘要

Synthesis gas is one of the most important intermediates in the chemical and petrochemical industries. There are various processes for synthesis gas production, and each has advantages and disadvantages. In this article, a process is introduced for producing synthesis gas based on a gas-heated reformer (GHR). By burning part of the input natural gas in a pressurized furnace and conducting the produced hot gases to the GHR shell, the heat of reactions taking place in the GHR tubes can be supplied. The other part of natural gas is converted to synthesis gas in the GHR tubes. Exit carbon dioxide from the furnace can be separated and left to react in the reformer as a feed. Compactness, low environmental pollution, flexibility in H_2/CO ratio of product gases, and no need for O_2 are some features of this process. A GHR reformer has been modeled and discussions and conclusions have been made by computer simulation of the reformer and process.
