Process Economics of Coal-Based Olefins .

Process economics are presented at three integration levels: coal gasification, methanol production, and finally integrated olefins production. We also evaluate the economics of olefins production based on consumption of outsourced methanol such as Sinopec's Puyang project and compare the results to the economics of integrated coal-to-olefins production. In addition, we compare the process ...

Coal Carbonization for Coke Production – IspatGuruTraduire cette page

Coal carbonization is the process by which coal is heated and volatile products (liquid and gaseous) are driven off, leaving a solid residue called coke. Carbonization of coal involves heating coal to high temperatures either in the absence of oxygen (O2) or in control quantity of O2. A gaseous by-product referred to as coke oven gas (COG) along with ammonia (NH3), water, and sulphur compounds ...

Introduction to Ammonia Production | AIChE

Haber finally developed a process for producing commercial quantities of ammonia, and in 1906 he was able to achieve a 6% ammonia concentration in a reactor loaded with an osmium catalyst. This is generally recognized as the turning point in the development of a practical process for the production of ammonia in commercial quantities. Haber realized that the amount of ammonia formed in a ...
