It is very importan

3、t in national economy. In recent years, with the development of the products that are made from methanol, especially the popularization and application of the fuel of methanol, the demand for the methanol rises by a large margin. In order to satisfy economic developments demands for methanol , have

4、launched the methanol project of this 200,000t/a. Main content that design to carry on craft prove, supplies weighing apparatus regard as with heat weighing apparatus charging etc The principle of the design in line with according with the national conditions, technologically advanced and apt, economy, protecting environment,. Coals is adopted as raw materials; the craft of GSP gasification is utilized to make water gas; the craft of NHD purification is utilized to purify the syngas; tubular
