PTA is the English abbreviation of PureTerephthalicAcid, and it is one of the important bulk organic raw materials. Its main use is to produce polyester fiber (polyester), polyester bottle chips and polyester films, which are widely used in chemical fiber, light industry, electronics, construction and other aspects of the national economy.

The application of PTA is relatively concentrated. More than 90% of PTA in the world is used to produce polyethylene terephthalate (PET), and other parts are used as raw materials for polypropylene terephthalate (PTT), polybutylene terephthalate (PBT) and other products.

PTA production process can be divided into two parts: oxidation unit and hydrofining unit. The raw material PX is oxidized into crude terephthalic acid by air with acetic acid as solvent under the action of catalyst, and then the crude product is obtained by crystallization, filtration and drying in turn. Crude terephthalic acid is hydrogenated to remove impurities, then crystallized, centrifugally separated and dried to obtain PTA finished products.

Note: naphtha processing difference is 30, PX processing difference is 240 and PTA processing fee is 500.

short staple

As the downstream product of PTA, polyester fiber is the largest and most widely used variety in chemical fiber, accounting for more than 80% of China's chemical fiber output. Polyester has the characteristics of high strength, good wear resistance, good light resistance and stiffness, but compared with natural fibers, it has the disadvantages of poor permeability, hygroscopicity and dyeability. Polyester is widely used in textiles such as clothing, bedding, various decorative fabrics and special fabrics for national defense and military industry, as well as industrial fiber products such as filter materials, insulation materials, tire cords and conveyor belts.

Production cost of staple fiber =0.855×PTA price +0.335× ethylene glycol price+other costs.

asphalt

Petroleum asphalt is the product of crude oil processing, which is black or dark brown viscous liquid, semi-solid or solid at room temperature. It mainly contains hydrocarbon and non-hydrocarbon derivatives soluble in trichloroethylene, and its properties and composition vary with crude oil sources and production methods.

Petroleum asphalt is not only of industrial significance for development, but also an important mineral for tracing and studying the formation of oil and gas reservoirs.

Asphalt cost = (Marui oil cost+freight+processing fee) -6.6%* Naphtha price -22%* Non-standard diesel oil price-1%* wax oil price /59.5%.

Coal preparation cost = (bituminous coal pit price * 1.6+ power coal pit price *0.5+800)*3+ 1200.

styrene

Styrene is an important basic organic chemical raw material. It is an organic compound, which is formed by replacing hydrogen atoms in ethylene with benzene. It is an important monomer of synthetic resin, ion exchange resin and synthetic rubber in industry.

It is mainly used to produce expanded polystyrene (EPS), polystyrene (PS), ABS and other synthetic resins and SBS elastomers. Downstream products are widely used in automobile manufacturing, household appliances, toy manufacturing, textile, paper making, shoe making and other industrial sectors. In addition, it can also be used as an intermediate in medicine, pesticides, dyes and mineral processing, and has a wide range of uses. "Upper bearing oil and coal, lower bearing rubber and plastic".

Meg

Ethylene glycol (EG), also referred to as "ethylene glycol", is an important basic organic raw material in petrochemical industry. Mainly used in the production of polyester fiber (polyester), polyester film, polyester engineering plastics, antifreeze and so on. It is also used to produce lubricants, plasticizers, hydraulic brake fluid, nonionic surfactants, glycol ethers, explosives, paints, inks, etc. , and has a wide range of applications. Globally, polyester products (including polyester, packaging resin, polyester film, etc.) account for about 90% of ethylene glycol consumption; In China, more than 74% of ethylene glycol is used to produce polyester and other polyacid fibers.

polyvinyl chloride

Polyvinyl chloride (PVC) is an inanimate and tasteless white powder with high chemical stability and good plasticity. According to the methods of obtaining vinyl chloride monomer, it can be divided into calcium carbide method, ethylene method and imported (EDC and VCM) monomer method (traditionally, ethylene method and imported monomer method are collectively referred to as ethylene method), among which ethylene method is the most in the world and calcium carbide method is the main one in China.

PVC is the largest general synthetic resin material in China and the second largest in the world. Mainly used in the production of profiles, profiles, pipes and fittings, plates, sheets, cable sheaths, hard pipes or hoses, blood transfusion equipment and sea membranes.

PVC cost = 1.45*( 1.55* thermal coal+1700)+ 1550.

polyethylene

Polyethylene (hereinafter referred to as PE) is one of the five major synthetic resins, and its output accounts for more than 40% of the total output of general resins in the world. It is the synthetic resin variety with the largest output and the largest import in China. At present, China is the largest PE importer and the second largest consumer in the world.

PE is mainly divided into three categories: linear low density polyethylene (LLDPE), low density polyethylene (LDPE) and high density polyethylene (HDPE). LLDPE products are non-toxic, tasteless and odorless, with milky white particles. The main application fields are agricultural films, packaging films, wires and cables, pipes and coating products. LLDPE is mainly used to make films because of its high tensile strength, puncture resistance and tear resistance. At present, the biggest consumption field of LLDPE in China is movies, accounting for 74% of the total LLDPE consumption, of which agricultural films account for about 24%.

LLDPE oil production cost = (Brent +4)*7* exchange rate *1.13)+685 *1.3+660.

polypropylene

Polypropylene (PP) belongs to thermoplastic resin and is one of the five general synthetic resins. The appearance is white and granular, tasteless and nontoxic. Because of the regular crystal structure, it has the advantages of easy processing, high impact strength, good flexibility and good electrical insulation, and is widely used in automobile industry, household appliances, electronics, packaging, building materials, furniture and other fields.

PP Oil production cost = {(Brent +4)*7* exchange rate *1.13+685} *1.3+800.
