How much PX is in a PTA?
PX is mainly used in producing PTA. In China, 97% of PX is used in producing PTA, with the other 3% of PX is used as DMT (i.e. medical intermediate) and paint. The upstream product of PX is crude oil, naphtha and the downstream product of PX is PTA and polyester chemical fiber.
What is PTA and MEG?
Purified terephthalic acid (PTA) and mono-ethylene glycol (MEG), two key raw materials used to make synthetic yarn. There are very few manufacturers and suppliers of polyester raw materials PTA and MEG. Yarn makers mostly have to dependent on domestic raw materials.
What is Meg polyester?
ETHYLENE GLYCOL POLYESTER GRADE. Produced using technology licensed by The Dow Chemical Company. Name : Monoethylene Glycol CAS number : 107-21-1 Formula : C2H6O2 Monoethylene glycol is a colorless, practically odorless, low-volatility, low-viscosity, hygroscopic liquid.
What is PTA polyester?
Eastman™ Purified Terephthalic Acid (PTA) is used to manufacture polyester coatings resins for use in the formulation of general metal, appliance, automotive, industrial maintenance, and coil coatings. The primary application for PTA is in combination with Eastman NPG™ Glycol in polyester powder coating resins.
How is Meg made?
MEG is produced from ethylene via ethylene oxide, which in turn is hydrated by using either a thermal or catalytic production process. Shell is a leading global producer of MEG, with world-scale plants in key markets, a global customer base and proven global logistics capability.
What is PTA material?
Purified Terephthalic Acid (PTA) is a white crystalline commodity powder and an important organic compound used as a precursor to thermoplastics, like PET (polyethylene terephthalate). Products from PTA include polyurethanes, powder coating resins, polyester fabrics, films, and plastic bottles.
What is PTA used for?
PTA is primarily used to produce polyester fibers and yarn. It is also used to manufacture plasticizers, liquid crystal polymers, and polybutylene terephthalate.
What is Meg tank?
Under the proposed concept for a MEG injection system, MEG is temporarily stored in a seabed storage tank and subsequently injected into the subsea flowline. Then, the MEG is recovered as rich MEG from the topside and regenerated as lean MEG through the standard regeneration process.
What is Meg fluid?
Mono ethylene glycol (also known as MEG, EG, 1,2-ethanediol or 1,2-Dihydroxyethane) is an organic compound with the formula C2H6O2. It is a slightly viscous liquid with a clear, colourless appearance and a sweet taste that emits virtually no odour.
How is PTA produced?
Terephthalic acid is produced from p-xylene by oxidation with oxygen. The reaction is carried out in acetic acid and the catalyst used is cobalt (or manganese) acetate and bromide. Phthalic anhydride is made from naphthalene or o-xylene by air oxidation over a heterogeneous catalyst.
What is Meg solution?
1 Monoethylene Glycol Regeneration and Reclaiming. The condensate may contain MEG solution, which is used for hydrate control in subsea pipelines. The glycol solution is contaminated with salts, corrosion inhibitors, and pipe scales, which must be removed to avoid fouling in the downstream process equipment.
What is Meg coolant?
Universal Antifreeze Blue (MEG) is an Mono Ethylene Glycol based antifreeze and summer coolant complying with BS 6580-92. It is non-flammable and contains no alcohols and is nitrate, amine and phosphate free. It is corrosion resistant for at least 2 years.
