Oil content, mg/kg for top grade ≤ 5 (by gravimetric method) and ≤ 2 (by infrared spectroscopy). Iron content, mg/kg for top grade ≤ 1. Uses: It is mainly used in the production of nitric acid, inorganic and organic chemical products, chemical fertilizers, as well as as a raw material in industries such as refrigeration, metallurgy, and pharmaceuticals. Packaging: The steel cylinders or tank trucks used for filling liquid ammonia must comply with relevant regulations such as the \"Regulations on the Safety Supervision of Gas Cylinders\" and the \"Regulations on the Safety Supervision of Pressure Vessels\" issued by the former **Ministry of Labor. The allowable weight filling coefficient is 0.53 Kg/L. Cylinders or tank cars should be regularly cleaned and dried as part of the purification process. Storage and transportation: Steel cylinders and tank trucks used for transporting liquid ammonia must comply with the \"Rules for the Transport of Dangerous Goods\" established by the Ministry of Transport of the People’s Republic of China. Liquid ammonia cylinders should be stored in a warehouse or on a sheltered platform ； When stored outdoors, it should be covered with a tent to prevent direct sunlight. Precautions: Liquid ammonia is highly corrosive and toxic. Those involved in transportation, use, and testing must strictly comply with the relevant provisions of standard GB536-88.

Liquid ammonia (GB17877-1999) --> **Standard

GB 17877-1999 Valves for liquid ammonia cylinders; HG 2599-1994 Technical requirements for liquid ammonia road tankers; GB 536-1988 Anhydrous liquid ammonia

Liquid ammonia (GB 536-86): Category – Manganese-based; Products – Metallic manganese, electrolytic metallic manganese, others. Keywords: Electrolytic metallic manganese, liquid ammonia, liquid ammonia standards. **Abstract of the standard: This standard applies to liquid anhydrous ammonia (liquid ammonia) produced by the direct catalytic synthesis of hydrogen and nitrogen under high temperature and pressure. Its main uses are in the production of nitric acid, inorganic and organic chemical products, chemical fertilizers, as well as in the fields of refrigeration and metallurgy... Cylinder valves for liquid ammonia GB 17877-1999 was issued on October 10, 1999, and came into effect on June 1, 2000. 1 Scope: This standard specifies the basic types, technical requirements, testing methods, inspection rules, marking, packaging, transportation, and storage of cylinder valves for liquid ammonia (hereinafter referred to as valves). 　　This standard applies to valves on liquid ammonia cylinders with an operating temperature of -40 to +60°C and a nominal operating pressure of 3 MPa. 　　This standard does not apply to valves on liquid ammonia equipment. GB8507 \"Sampling of Liquid Anhydrous Ammonia Laboratory Samples\" – This standard; the design standards for liquid ammonia storage tanks are based on GB150 and JB/T4750

Liquid ammonia (GB17877-1999) –> **Standard; that’s all that’s needed.

Today, my topic was enabled; at the beginning of the month it was disabled, I don’t know why. Having worked in ammonia synthesis for so many years, I’m not familiar with the **standards** for liquid ammonia. Shameful

I don’t know why; I’m not able to give everyone 10 points. The maximum score I can give is 2, and I can’t give additional points either. I really want to give each of the experts here 10 points. I have 116 points at the moment, so all I can do is express my gratitude verbally. What’s the difference between the GB17877-1999** standard and the GB536-88** standard? Are both of them quality standards for liquid ammonia products? Are they both in use at the same time?
