Major consumption of natural Gas is using it as fuel to provide energy to all sectors. Though it is also being used as feedstock for chemical industry to produce ammonia/urea and methanol. Although ammonia and methanol may also be produced from other feedstock, the most economical way of producing these two products is through Natural gas

Methanol is one of the most important petrochemical products which is mostly used as raw material to produce large variety of downstream products. About 85% of produced methanol is used as raw material in chemical industry and other 15% is used as energy carrier

Methanol can be made from a wide array of feedstocks, making it one of the most flexible chemical commodities and energy sources available today. To make methanol, you need first to create synthesis gas, which contains carbon monoxide and hydrogen gas as its main components 

While natural gas is most often used in the global economy to produce methanol, this product has the distinct advantage of 'polygeneration' - whereby methanol can be made from any resource that can be converted first into synthesis gas. Through gasification, synthesis gas can be produced from anything that is or ever was a plant.  This includes biomass, agricultural and timber waste, solid municipal waste, and a number of other feedstocks. However, because of the production costs and also availability of cheap natural gas in some regions of the world, which have access to NG, most of methanol production is being done, based on natural gas. Except Northeast Asia, North America and west Europe, in all of other points of the world methanol is being produced based on NG

The other product in which production technology is mostly based on natural gas, is ammonia while its major application is in the field of agricultural industry using as different types of fertilizer

Thanks to Iran’s huge natural gas reserves, considering having access to cheap raw material, production of both methanol and ammonia are potentially feasible. Thus, in this study, feasibility of integrated methanol and ammonia production based of natural gas as feedstock is being studied

Considering existing technology, the capacity of production is considered as 1,000 kta methanol in addition of 300 kta ammonia
