Steam reforming of natural gas at petroleum refining facilities is the predominant means of producing hydrogen in the chemical process industries (CPI). Areas where hydrogen is heavily consumed include ammonia production, the cryogenics industry and methanol production (Table 1)[1]. Because hydrogen needs within various sectors of the CPI are at their highest levels in history, and are continuing to grow, an understanding of this method of hydrogen production and purification can be useful. Table 1. Hydrogen Usage by Industry Hydrogen final usage category Usage by industry (%) Comments Ammonia 37 An ammonia plant is typically a hydrogen plant with a second converter that reacts hydrogen with nitrogen Merchant 3 This includes all bottled users, liquid hydrogen supplied in tank trucks, and gaseous hydrogen in short pipe lines (not including the over-the-fence hydrogen suppliers) Methanol 10 Refinery hydrogenation 19 …
