Feedstock methanol, thermal efficiencies

The SVZ plant produces synthetic gas or fuel gas at atmospheric or elevated pressure, with the recovery of minerals in slag. There is a partial gas conditioning (CO shifting), a gas pnrification system with flue gas desulphurization. This plant is characterized by a high thermal efficiency and a flexible feedstock. A 120 000 t/a methanol plant is associated with it. 

Thermal efficiencies for converting corn stover (8), furfural residue (8), and wood residue to methanol were estimated from the published data to be 48.0, 48.0, and 45.3% respectively. The efficiency data used for converting wood to methanol via the Purox process is also in good agreement with recently published data (12). The Purox process may not have been the best choice for the gasification (1 ). but process and economic data are available for all three feedstocks considered in this paper.
