AhmadRezaGharibi

Zagros petrochemical company is located in Pars Special Economic Energy Zone and produces 1.6 million tons per year of methanol. It obtains natural gas feedstock from the South Pars Gas Field. The company has several operational units including a reforming unit, methanol synthesis unit, and distillation unit. The reforming unit removes sulfur from the natural gas via desulfurization reactors and then performs prereforming, steam reforming, and autothermal reforming to produce syngas for the methanol synthesis unit.
