Zagros Petrochemical Company was established in 2000 to implement Iran's third economic, social and, cult development plan with the aim of achieving global markets and gaining a considerable share of the methanol market. For the purpose of empowering the company to compete worldwide and also taking into account the rich gas resources in the South Pars region and its strategic location, a 31-hectare land in the South Pars Special Economic Energy Zone was acquired and the company's production complex was constructed in Assaluyeh port. Moreover, the complex is designed in a way to use the maximum energy produced in the synthesis reactors and at the same time utilize the recycled energy in the reforming unit to supply the required energy. As a result, approximately 205 tons of steam per hour with a pressure of 40 bars are produced and sold.

Therefore, a contract for basic and detailed engineering as well as equipment purchase was signed with a consortium consisting of companies Lurgi, Germany and Pidak, Iran and all activities related to the construction and installation operations were undertaken by Iranian contractors.

Following the contract with Lurgi and Pidak companies, the first phase started in 2001 and ended in 2006 with an annual capacity of one million six hundred and fifty thousand tons of AA grade methanol. Besides, upon completion of the complex's second phase in 2009, Zagros Petrochemical Company was included in the list of five largest methanol-producing companies in the world with an annual production capacity of three million and three hundred thousand tons.
