Urea synthesis using chemical looping process – Techno-economic evaluation of a novel plant configuration for a green production

摘要: Abstract Chemical looping is an attractive technology which can produce three pure streams of N 2 , H and CO . In this paper, for the first time, a novel green plant configuration proposed urea production in chemical process used as primary stage to prepare feedstock synthesis unit. The intended by reduction number operating units within heat power integration provides significant potential investment cost reduction. Due also economically valuable intermediate NH 3 more technical flexibility compared conventional technologies. Economic evaluation shows considerable rate return financial interest. different rate, has (IRR) above 28%, while IRR plants almost near 20%. Moreover, combined presented produces without any by-product.
