WebDec 1, 2024 · The mass-energy balance of the entire process (from biomass gasification to the synthesis of methanol and DME) is useful for not only the process efficiency optimisation but also for the effective analysis of a given system configuration, which in turn translates into optimal process implementation. 2. Process simulation WebStenstrom, M.K. & Rosso, D. (2003) Fundamentals of Chemical Reactor Theory 3 Fig. 1. Batch reactor Given its volume V, and the initial internal concentration c0, the total mass will be M = V·c0. In the unit time, the concentration will be able to change only in virtue of a chemical reaction. The mass balance [6] quantifies this
