Coking Process - an overview | ScienceDirect Topics

James G. Speight PhD, DSc, in Oil and Gas Corrosion Prevention, 2014 2.3.2 Coking. Coking processes are processes in which the feedstock is thermally decomposed into lower boiling products. The major subforms of the coking process are (1) the delayed coking process and (2) the fluid coking process.. To a large extent, most cokers are constructed of Type 410 stainless steel, either claded (i.e ...

What is Coking Coal - Aspire Mining Limited

This is known as the caking process. The quality of the resultant coke is determined by the qualities of the coking coals used, as well as the coke plant operating conditions. Coke quality is largely influenced by coal rank, composition, mineral content and the ability to soften when heated, become plastic, and resolidify into a coherent mass ...

Coking Coal - an overview | ScienceDirect Topics

When coking coal to gasification coal ratio is 7, there is sufficient hydrogen supplied by the COG tri-reforming. The WGS unit can be cancelled in the new COG-CTM process, as shown in Figure 4.As the WGS unit is no longer needed in the COG-CTM process, the main operating parameters of the AGR unit and TRM unit will change accordingly.
