Abstract

The process of ammonia production from N2 and H2 with recycling of unreacted materials is investigated. The process is examined at relatively low pressure (48 bar) and temperature (190°C). CSTR isothermally runs under equilibrium condition. With recycling, it was found that a liquid product of NH3 with a purity of 99.3 wt. % was achieved. The waste is minimized with potential use as a fuel. Aspen process economic analysis was also carried out. It was found that such an investment project is profitable with a payout (payback) period of 4.2 years and modified internal rate of return (MIRR) of 21.5 %. The total capital cost was found to be $ 10,300,600 and the total operating cost to be $ 15,439,500/year for an annual production of ammonia of 30,046 tonne/year.
