Dynamic process models for the coal DMS process are limited in the available published literature (Meyer and Craig, 2010). Steady-state models developed by Napier-Munn (1991) cannot be used for process control purposes due to the need for time-varying process variables. DMS process models developed by Lyman et al. (1982) and

Carbon dioxide capture is a high energy process, this is due to solvent regeneration of MEA from the reboiler, which often accounts for up to 4.0 GJ/tonne of CO 2 and can be minimized using newer solvents (e.g. ammonia/NaOH instead of MEA ) or refinement of the coal-fired operational parameters or process engineering in how the …
Loading the Retort: The crushed coal is loaded into airtight containers called retorts. These retorts can be horizontal or vertical vessels designed to withstand high temperatures. Heating in the Absence of Air: The retorts are sealed to create an oxygen-free environment, and then heat is applied. The temperature is typically raised to a …
