Coal is more abundant and cheaper than oil and natural gas, but it exhausts high carbon dioxide gas (co 2) and sulfur content of the environment load at the time of the use.Clean coal technology (cct), which uses coal in high efficiency and clean, is a key technology to reduce the discharge of the material having high environmental load.
The ammonia production process passes through a number of stages, from desulfurization and the primary reformer to the synthesis reactor.The composition of the material flow must therefore always be closely inspected.Any fluctuations would impact on all subsequent stages, and so the consequences for process quality and efficiency would be.
