Description
Summary:Production of three pure streams of H2, N2 and CO2 makes the chemical looping reactors as an attractive intermediate technology to provide the feedstock of ammonia synthesis loop. As a goal of paper, for the first time, a novel and green plant configuration using three chemical looping reactors is proposed for ammonia production in which needed hydrogen and nitrogen are produced by means of a process simpler than the conventional technologies. Due to the reduction in plant units and also 30% increase in production ratio and simultaneously production of economically valuable by-products of H2, N2 and CO2, significant potential for investment cost reduction along with CO2 capture and storage can be anticipated. Moreover, the proposed plant for ammonia production is very flexible in terms of adjusting the desired main products. [Display omitted] •Three pure N2, H2 and CO2 stream are produced in TRCL.•Operating conditions guaranteeing production of three pure streams are discussed.•A novel ammonia plant is introduced using N2 and H2 streams of TRCL.•Proposed plant shows a significant potential for investment cost reduction.•Proposed plant is flexible in adjusting the desired products.
