SM is a kind of transparent or light-yellow oil-like liquid with special fragrance.
SM as one of the most important monomers in chemical industry, is widely applied to make PS,EPS,ABS,SAN,UPR,SBR,SBL,SBS etc. It is poisonous and can make damage to skin and eyes. Gasified SM is a stimulus to respiratory tract and eyes, leading to dizziness, and unconsciousness in the worse case.
SM is stored in carbon-steel or stainless steel tanks. Static electricity and fire shall be avoided, and contact with copper, copper alloy and oxygen shall be prevented.
SECCO SM unit adopts ABB/Lummus's proprietary EB/SM technology with the capacity of 500ktpa, one of the units in the country, and the product quality meets GB 3915-90 and ASTM D2827 standards.
Ethylene Ethylene is produced by steam cracking Naphtha and other hydrocarbon streams. Ethylene (C2) is a colourless gas with a slightly sweet smell. SECCO uses ethylene to make polyethylene, styrene and polystyrene, which in turn are used to manufacture a wide variety of products from food packaging to toys. It is of fundamental importance to the plastics industry and is the basic building block of organic chemistry.
Propylene Propylene (C3) is a colourless gas. It is highly flammable and can be used as a substitute for LPG (Liquefied Petroleum Gas). It is easier to transport propylene than ethylene as it can be liquefied at much lower pressures and is conveyed in its liquid form. SECCO uses propylene to make polypropylene, a plastic used in cars and toys, and acrylonitrile, a chemical used to make acrylic fibres.
Butadiene Butadiene (CH2=CH-CH=CH2) is a colourless gas with a slight sweet and fragrant odorodour at room temperature; is soluble in organic solvents, insoluble in water; is inflammable and its explosion limits ranges between 2% and 11.5%. As one of key petro-chemicals, it is mainly used for manufacture of various synthetic rubbers (SBR, NBR, PBR), also for process of synthetic resin, fibres and fine chemicals, such as ABS, BS & SBS etc.
Toluene Toluene is a colourless liquid with a sweet, pungent, benzene-like odorodour; is flammable and produces poisonous gas in a fire; containers of it may explode in fire. It is slightly soluble, and incompatible with strong oxidizers. As one of key basic chemical materials, it is widely used in the manufacture of other chemicals and as an ingredient in fuel, paint, glues and adhesives.
Acrylonitrile Acrylonitrile, or Cyano-ethylene (CH2=CH-CN), is a colourless inflammable liquid with drastic toxicity and irritation irritating smell; dissolves slightly in water and quite well in common organic solvent. There exists the danger of burning and explosion when it meets with fire, high temperature and oxidants. Acrylonitrile vaporvapour and air can form an explosive mixture with the explosion limits between 3.1%-17%(vol.). The boiling point is 77.3°C, the flash point -5°C and the self-ignition point 481°C.
SECCO will manufacture it by direct oxidation by using propylene, ammonia and air as raw materials, which is the leading technology licensed by BP.
It is used for manufacture of synthetic rubber, synthetic resin, dyestuff and medicine.
Acetonitrile Acetonitrile, or methyl cyanide (CH3CN), is a colorlesscolourless liquid with drastic toxicity and aromatic smell; the flash point is 5.56°C (open cup) and the self-ignition point 525°C, the explosion limits of its vaporvapour and air mixture between 4.4%-16%(vol).There exits the danger of burning and explosion, if it encounters fire, high temperature and oxidant. It reacts actively with sulphuric acid, fuming sulphuric acid, chlorosulfonate. It is soluble in water and alcohol .
SECCO will manufacture it as a by- product of acrylonitrile by using propylene, ammonia and air as raw material, which is the leading technology licensed by BP.
It is used as an extraction solvent for butadiene and aliphatic acid, calodorant, non-ferrous metal floating agent. It is also a raw material for aromatizer, medicine and agricultural pesticide.
