Sulfur storage method (3)

Sulfur poisoning occurs, if skin contact, is to take off contaminated clothing, wash thoroughly with soap and water skin. In case of eye contact, use mobile or saline irrigation water, and medical treatment. The case of inhalation poisoning, make poisoning quickly from the scene to fresh air, keep the airway clear.
Sulfur, a fire occurred, the case of small fire out with sand boring. Dry powder fire extinguisher case of fire can be used. Do not spray water directly to the melt in order to avoid a serious fire or cause severe flow boiling splash. Firefighters have to wear gas masks, at a safe distance away, fire in the wind.

Sulfur leak in the event of accident, leak contaminated areas should be isolated, restricted access, and cut off the fire. Emergency personnel should wear self-absorption filter respirators, the general work clothes to wear. Personnel do not direct contact leakage. A small amount of leakage, to avoid dust, use a clean shovel to collect spill in a dry, clean, covered containers transferred to a safe place. A lot of leakage, use plastic sheeting, canvas cover and reduce the flying, and then use non-sparking tools to collect recycling or shipped to the disposal of waste disposal sites.
Contact with the general staff of sulfur does not require special protection, wear protective gloves general operations, you can wear normal clothes. When the dust concentration in air is high, wear self-absorption filter respirators.

Sulfur storage method (1)

Although toxicology, the sulfur is a low toxicity of hazardous chemicals, but steam and sulfur dioxide after combustion occurs on the human body are highly toxic. With halogen, metal powders severe reaction occurs after contact. Sulfur for the poor conductor, in the storage and transportation process will produce electrostatic charge can also lead to sulfur dust fires. Dust mixed with air or oxidizer will form an explosive mixture.
　　Sulfur after the incident, the general will appear inhalation, ingestion, absorption through the skin in several ways. Part of their energy into hydrogen sulfide in the intestine and is absorbed, it can cause a large number of oral hydrogen sulfide poisoning. Acute systemic toxicity of hydrogen sulfide poisoning in the performance of the central nervous system symptoms, headache, dizziness, fatigue, vomiting, coma.

Accumulation of sulfur what should we pay attention to?

　　Solid sulfur product is flammable solids, should be stored in a cool, ventilated warehouse, storage and transportation should be away from fire, heat and avoid burning, and can not be mixed oxidant and phosphorus and other items mixed reservoir operation, in order to prevent an explosion. During transport, should prevent the casual bags, to avoid sulfur powder form explosive mixtures with air. Liquid sulfur stored in the storage tank with insulation in.

　　Note: the warehouse cannot be halogen, phosphorus, metal powders, antioxidants and other things mixed storage. Cause severe reaction, such as exposure. Regular inspection: check storage temperature, check mixed reservoir, and check moisture. Handle with care discharge, so that damage to packaging and bulk packages. Storage of electrical lights, fans should be explosion-proof; the switch should be located outside the warehouse. We should be equipped with sand and fire fighting equipment.

International sulfur prices in mid-July

　　Mid-July, the price has fallen and the international trend of sulfur, a decrease of 5-20 dollars (t value, the same below).

　　FOB solid sulfur: at early July, Iran 75-90, 9 low-end prices, high prices 10. Kuwait 70-88, 20 low-end prices, high prices 7.Saudi Arabia 70-88, 20 low-end prices, high prices 7.

　　Liquid sulfur CIF: Mediterranean’s price is 80-100, 15 low-end prices; high prices 10.The price of Northwest Europe region is 95-100, 5 low-end prices, and high prices 10. Belgium’s price is 94-105, 11 low-end prices, high prices 9. Netherlands’s price is 94-105, 11 low-end prices, and high prices 9.

Market Analysis of Sulfur (2)

Since February, however, the downstream concentration of compound fertilizer and other purchased large quantities of sulfur peak has passed, the limited demand, coupled with some downstream manufacturers shut down the Spring Festival, the sulfur prices have stabilized. In East China market, for example, years ago, Port Sculpture mainstream price 1280 Yuan / ton, refinery price stability in 1200-1300 Yuan / ton.

　　According to industry analysis, the domestic petrochemical industry to embark on the road to recovery, the majority related to rising prices of chemical products. According to “in February as energy, chemical market rating” data show that in February the main chemical industry products are still rising, especially sulfur, octane market was the most eye-catching.

Market Analysis of sulfur (1)

　　Sulfur is an important inorganic pesticides in variety. China sulfuric acid was about 70% of the raw materials for fertilizer production. In the system of law, most of sulfuric acid with the waste heat recovery method.

　　Since October 2009 has been subject to international Sulfur prices continued to rise and impact of domestic demand for phosphoric acid, sulfur, continuous price rise, which, of solid sulfur from 600 Yuan / ton up to 1,300 Yuan / ton.

Preparation or sources of choline chloride

　(1) 20% trim ethylamine aqueous solution react with the concentration of ethylene oxide. After that, derive it to hydrochloric acid.

　　(2) Methanol in the choline solution, adding hydrochloric acid, It will be obtained, and then refined;

　　(3) Of anhydrous ethanol and trim ethylamine chloride reaction. Reaction carried out at 50 ℃.

Choline chloride storage

　　Choline chloride liquid storage temperature should not fall below 120 Degrees Celsius, in order to avoid crystallization, and it blocked pipe.

　　Choline chloride powder stored in silos in the product should be used to prevent from getting moist. Choline chloride powder will cause the product after moisture absorption and caking resulting wet pipe plug. Vector-based choline chloride powder Plant, after long-term moisture situation, there may be fermented.

Choline Chloride drug use

　　Choline Chloride drug use

　　1) Choline Chloride can be used to treatment of fatty liver and cirrhosis.

　　2) Choline can be used as livestock feed additives. Choline chloride can stimulate the ovaries more eggs.

　　3) Choline Chlorides can stimulate the animal litter.

　　4) Choline Chlorides allows livestock and fish such as weight gain.
