واحد سولفات آمونیوم پتروشیمی ارومیه در سال با ظرفیت هزار تن در سال، برای تولید سولفات آمونیوم پودری راه اندازی شد؛ این واحد در مرحله اول توسعه از ظرفیت هزار تن در سال به هزار تن و در مرحله دوم به هزار تن در سال افزایش یافت. در مرحله سوم توسعه واحد گرانول سازی نیز به این مجموعه اضافه شد.

مجتمع پتروشیمی رازی در زمینه فعالیتهای کشاورزی و باغداری محصولاتی از قبیل کود اوره و کود دی آمونیم فسفات (DAP) و در زمینه فعالیتهای صنعتی محصولاتی همچون گوگرد دانه بندی شده، آمونیاک و اسید سولفوریک به مشتریان خود عرضه می نماید.

Gunpowder production: This material is used to make bullets and gunpowder inside missiles and cannons and is of particular importance. Match production: which has incendiary properties, is used in the production of matches and incendiary substances.• In making colors as well as making fibers.Like carbon, it has been used in fireworks for a long time.Alchemists also used different combinations of this substance with mercury metal.

Introduction: Elemental sulfur is byproduct of natural gas refining which during this process, HS is removed from sour gas and after changes to solid sulfur, it is stored in large block forms. Continuous precipitation of sulfur and its oxidation causes soil acidification and as a result, nutrient cations such as Ca+, Mg+, Na+ and K+ will leach from the soil profile. Also, sulfate accumulation led to soil acidification and accelerates the silicates weathering in upper layer of the soil profile. Accumulation of water soluble sulfate in the soil and increase the nutrient cations leaching from the soil depend on sulfate resistance rate. Also, addition of sulfur to the soil for a long time can cause calcium sulfate formation that will cause problems such as increase in soil salinity. Shahid Hashemi Nezhad gas refinery is located about km south of Sarakhs city and about km east north of Mashhad. In addition to exploiting, refining and producing × m.day- natural gas, recovered sulfur with %/ purity and tons per day production capacity is one of the byproducts of this gas complex.

Sulfur is one of those elements that has a clear past. Its origin and use date back to centuries ago, the time when the Greeks used this substance to disinfect their homes and the properties from burning it. They took.Mankind has mentioned the existence in Sicily and Italy for centuries. Its common name in the past was brimstone and it means a burning stone. In the Bible, sulfur is given the same name.
