The Group’s principal products are gasoline and diesel oil produced through oil refining operations, as well as speciality chemical and biochemical products.

Oil refining

The refining process can produce a range of useful products such as liquid petroleum gas, petrol, diesel, jet fuel, gas oil, heating oil and residues such as bitumen. Refining also provides the feedstocks for lubricants and petrochemicals which, as outlined earlier, are the basis for plastics, paints, adhesives, detergents, resins, solvents, synthetic fibres and rubber.

Dimethyl Carbonate (DMC)

DMC is a colourless liquid, produced from a chemical reaction between propylene oxide and methanol. With an added catalyst, it is synthesized through the processes of fractionation and filtration. DMC is used widely in medical applications, agricultural pesticides and the manufacture of synthetic materials. It is an important additive to lubricating oil, solvents and gasoline as well. DMC is also used in the electronics chemistry.

Propylene Glycol

Propylene glycol is a colourless, odourless, oily liquid. It is an associated product from the production of DMC. It is generally recognised as a safe and stable compound that can be used in food, cosmetics and medicine. Among a wide variety of applications, it is commonly used as a moisturiser and a lubricant in pharmaceutical products. Industrial applications include polyester resins, silica gels and agents in plastics production. Propylene glycol can also be used as a substitute for ethylene glycol in antifreeze and hydraulic brake fluids for aircraft.

Isopropyl Alcohol

IPA is colourless, flammable compound with strong odour. It is produced through propylene hydration reaction catalysed under pressure. It is used widely in medical markets as a sterilising product when mixed with water. Other uses include its use as a cleaner or solvent for industrial purposes or as a gasoline additive for dissolving ice or water in fuel lines. It is highly effective when used as a cleaning agent for electronic devices such laser lenses in optical disk drives (i.e. CD, DVD) or computer monitor screens.

Sodium Hydroxide

Sodium hydroxide (NaOH) is also known as lye or caustic soda. This compound is a caustic metallic base (an alkali). Caustic soda is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, and detergents. Sodium hydroxide is also the most common base used in chemical laboratories. Sodium hydroxide is usually handled as an aqueous solution and is often used as a neutralising agent for acidic material. It is often used as such in petroleum refining. Caustic soda flakes in a solid form are also manufactured.

Liquid chlorine

In its natural state, chlorine is a yellow-green gas which has the ability to combine with other elements. In this case it is combined with water to form a liquid. Chlorine is a respiratory irritant and as a liquid, it will burn the skin in its pure form. Chlorine is used primarily to sterilise and disinfect and as a component of bleach. Common applications include killing bacteria in drinking water and swimming pools. It is only used in a range of industries including pulp and paper production, paints, insecticides and petroleum products such as solvents and textiles. It also has uses in the manufacture of plastics and rubber. Common salt is a major component in the production of chlorine. This is all sourced from the company’s salt field which produces in excess of 50,000 tonnes of salt used in the production process.

Heparin sodium; Enoxaparin sodium; Dalteparin sodium

Heparins are predominantly used in the pharmaceutical industry as injectable anticoagulants, used to prevent the formation of blood clots in humans. The company’s production facilities, which are based in Dongying, are comparable to the equivalent high specification requirements that currently exist in the US or Europe.
