This paper has proposed and investigated an integrated industrial complex designed to produce ammonia, and nitric acid, nitrogen, green hydrogen. This integrated industrial complex consists of four manufacturing subsystems: (i) an alkaline water electrolysis process (AWEP), (ii) an air separation unit process (ASUP), (iii) an ammonia synthesis process (ASP), and (iv) a nitric acid synthesis process (NSP). The AWEP subsystem generates green hydrogen and oxygen. The ASUP subsystem separates air to generate nitrogen and oxygen. The nitrogen reacts with green hydrogen in ASP subsystem to produce ammonia. Further, ammonia produce will be used as product and will also be utilized to react with by-product oxygen from the AWEP or ASUP subsystem to produce nitric acid in the NSP subsystem. Note that the renewable energy source such as solar power will be supplied to empower all the subsystems featuring its environmental and energy supply sustainability. Thus, this industrial complex will utilize the major feedstock such as water and air with the support of renewable energy to produce pure O2, green ammonia, nitric acid. In this paper, rigorous modeling, simulation, comprehensive economic analyses, and sensitivity analysis have been conducted with Aspen Plus V14 to demonstrate the viability and economic efficiency of this integrated industrial complex development.
