TFL has been mandated by the Government to revive the erstwhile Talcher plant of FCIL by setting up a new coal gasification based Urea Plant with the installed capacity of Lakh Metric Ton per annum (LMTPA). Since the project promotes coal gasification, it shall also aid in meeting the stated aim of gasifying 100 MT of coal by 2030.

1. Introduction. Urea (NH 2 CONH 2) was firstly artificially synthesized using two inorganic molecules as feedstocks from Friedrich Wöhler in 1828 [1].A breakthrough is through pyrolyzing ammonium carbamide to urea in 40 years latter [2].Subsequently, industrial urea production (BoschMeiser process) was first developed in 1922 [3].This pathway involves two steps: (i) liquid ammonia (NH 3 ...

Coalbased power plants are largest emitter of CO2 as a single sector. To use fossil fuels (including coal), CO2 capture and storage is a visible option. But large energy requirement for this process and risk associated with storage of CO2 demand alternative solutions including recycling of captured CO2. In this paper, a coproduction of power and urea is proposed using coal with captured CO2 ...
