Introduction to Ammonia Production AIChE
the total annual production of synthesized ammonia was just over 300,000 mt Thanks to chemical engineering breakthroughs, one modern ammonia plant can produce more than 750,000 mt/yr Approximately 88% of ammonia made annually is consumed in the manufacturing of fertilizer Most of the remainder goes into the production of formaldehyde The leading method for the industrial production of ammonia has been the HaberBosch process for nearly a century worldwide The overall process requires high temperatures and pressures and utilizes nitrogen fixation (reacting atmospheric nitrogen), continuous flow and the frequent recovery of unreacted gases, resulting in a method capable of producing large amounts of ammonia more Ammonia Synthesis for Fertilizer ProductionThe present chapter describes process technology for the production of ammonia The first part gives a short review of early developments in ammonia technology The second part contains a brief description of processes used in the production of ammonia synthesis gas, ie a mixture of hydrogen and nitrogen with or without minor amounts of impurities such as methane, argon, etcAmmonia Production Processes SpringerLinkFig (15) shows the Process Flow Diagram (PFD) for the production of ammonia process, generated by Aspen HYSYS 231 Selection of components list: In this simulation, the reactant component list contain CH 4, H 2O, CO, CO 2, N 2, H2, O 2 ignoring sulfur content as the components for the ammonia productionSimulation of Ammonia Production using HYSYS SoftwareFigure 422 KBR’s typical KAAPPlusTM process for ammonia production 58 Figure 423 Block diagram of a typical KBR’s new generation ammonia plant 59 Figure 424 Typical block diagram of a conventional and Linde designed ammonia production plant 61 Figure 425 Haldor Topsøe ammonia reactor (S300) (Embodiment of fixed three catalyst beds) 62 HNO3 MANUFACTURING WITH PROCESS FLOW DIAGRAM ammonia production block flow diagram windbornestudios
