Included activities starts

The activity starts with the production and import of "Methanol" in this region.

Included activities ends

The activity ends with providing the "Methanol" to the consumers of this product. Transportation is included; however, product losses during transport are negligible and therefore not included.

Description

This is a market dataset representing the consumption market in the region. It includes transportation of the product from the factory gate to consumption, with transport services calculated according to the regional transportation conditions for the product.

Activity Description

The production activities of this product include coal processing, coke production, and methanol production.

Process Description

Methanol is an organic compound with the molecular formula CH4O. It is a colorless, transparent, flammable, volatile, and toxic liquid with a pungent odor, exhibiting a slight alcoholic scent. It remains liquid under normal temperature and pressure conditions. Methanol is miscible with water and highly soluble in gasoline; its vapor can form explosive mixtures with air. This product is one of the key chemicals produced from synthesis gas and serves as both an important chemical feedstock and a fuel.

Technology comment

The process of producing methanol via the coke oven gas route can be roughly divided into three stages: coal processing, coke production, and methanol production. After mining and coal washing, bituminous coal undergoes pyrolysis in coke ovens at temperatures approaching 1100°C, yielding coke and a considerable amount of raw coke oven gas as byproduct. Similar to the coal-to-methanol route, the raw coke oven gas, after cooling, should be purified by removing impurities such as sulfur, ammonia, and raw benzene. To meet the requirements for methanol synthesis, the synthetic gas is also sent to a reforming reactor to adjust the appropriate H/C ratio (approximately 2). 5). Subsequently, methanol is produced in the synthesis reactor. Finally, refined methanol is obtained in the distillation unit.
