Process for producing high purity hydrogen gas using ammonia raw material gas

摘要

The present invention relates to a method for producing high purity hydrogen gas using a raw material gas required in an ammonia plant. More specifically, the present invention relates to a commercial production method of hydrogen gas which produces a large quantity of hydrogen gas having a purity of 99.2% by using an oxygen combustion method as a raw material gas required in an ammonia plant. In this method, a synthesis gas containing butane as a main component required in an ammonia plant The present invention relates to a method for producing high purity hydrogen gas having a purity of 99% or more, characterized by combustion reaction with oxygen gas having 98% or more of oxygen in the secondary reformer passing through the primary and secondary reformers, and removal of carbon monoxide and carbon dioxide.
