High pressure often means the sample has passed through multiple process units on its way to becoming valuable product well before analyzers like gas chromatographs can provide composition results. Ammonia production has increased steadily since 1946 (Figure 2), and it is estimated that the annual production of ammonia is worth more than $100 billion, with some plants producing more than 3,000 m.t./day of NH3. The Haber process provides a good case study to illustrate how industrial chemists use their knowledge of the factors that affect chemical equilibria to find the best conditions needed to produce a good yield of products at a reasonable rate.In the Haber process, “the atmospheric nitrogen (N2) is converted to ammonia (NH3) by reacting it with hydrogen (H2)”. Six process steps are required to produce synthetic ammonia using the catalytic steam reforming method: (1) natural gas desulfurization, (2) catalytic steam reforming, (3) carbon monoxide (CO) shift, (4) carbon dioxide (CO2) removal, (5) methanation, and (6) ammonia synthesis. 0000004106 00000 n
