CHEMICALS

PHOSPHORIC ACID

Phosphoric acid is an intermediary product between rock phosphate and plant fertilizers, phosphoric acid is a combination of rock phosphate and sulfuric acid. It is a metallic acid with the chemical nomenclature of (H3PO4), also called Orthophosphoric Acid. Phosphoric acid is an important industrial chemical used as an intermediate in the fertilizer industry, for metal surface treatment in the metallurgical industry.

SULFURIC ACID

Sulfuric acid is a mineral acid composed of sulphur oxygen and hydrogen. It is also known as sulphuric acid and vitriol. The chemical formula of the compound is H2SO4. It is a colourless and odorless hygroscopic liquid, which soluble in water. It is a highly corrosive acid, which possesses oxidizing and dehydrating properties.

Sulphuric Acid is needed to extract the Phosphorous content from Phosphate Ore or Rock Phosphate to produce Phosphoric Acid or Superphosphates. In a reaction with Ammonia, it forms Ammonium Sulphate. Concentrated Sulfuric Acid is rarely found in nature but is produced by burning Sulphur into Sulphur Dioxide (SO2). Sulphur Dioxide is oxidized at high temperature into Sulphur Trioxide (SO3).

SULPHUR

Sulphur is a multivalent non-metal, abundant, tasteless, and odourless. In its native form sulphur is a yellow crystalline solid. Sulphur is an important industrial raw material which is used in the manufacture of sulphuric acid, in the manufacture of sulphur dioxide and sodium sulphite which are used for bleaching straw and wood fibres, and for removing lignin from wood pulp for the paper industry, and in the manufacture of organic chemicals which contain sulphur. Please contact us for detailed quotation, we can supply sulphur in the form of lump, granule, and powder.

NAPHTHA

FULL RANGE NAPHTHA 
 

Full Range Naphtha (FRNAP) is a virgin naphtha with a typical boiling point range of 30-150°C and PNA (paraffinic: naphthenic: aromatic) content of content of 70:20:10. As a versatile naphtha, it has the potential to be used as a direct feedstock by petrochemical plants or into naphtha splitters for further processing. Total capacity 45 KT.

CAUSTIC SODA

Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air. CAUSTIC SODA forms a series of hydrates NaOH nH2O. The monohydrate NaOH H2O crystallizes from water solutions between 12.3 and 61.8 °C. The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound. As one of the simplest hydroxides, it is frequently utilized alongside neutral water and acidic hydrochloric acid to demonstrate the pH scale. It is a hazardous substance and highly reactive.

LIGHT NAPHTHA

Light Naphtha is a type of virgin NGL, recovered in gas processing section of the LNG plants. In the family of light naphtha (typical boiling point range of 35-140°C), it is highly paraffinic (typically >80%) and typically used as feedstock in petrochemical cracking plants.​

PARAXYLENE

Para-Xylene (PX) is a C8 aromatic compound that is used exclusively as an intermediate feedstock for polyester production via purified terephthalic acid (PTA) or dimethyl terephthalate (DMT).

Para-xylene is a versatile chemical feedstock used in the large-scale synthesis of countless polymers including PTA and PET for applications such as textiles, plastic packaging, clothing, automotive components, and more.

It is mostly produced from cracking of naphtha, but there is a need for new and cost-effective methods for the production. Toluene alkylation with methanol over an alumino-silicate zeolite catalyst, such as ZSM-5, produces a mixture of xylene isomers with low p-xylene selectivity.

PETCOKE

Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes. Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units termed coker units. (Other types of coke are derived from coal.) Stated succinctly, coke is the "carbonization product of high-boiling hydrocarbon fractions obtained in petroleum processing (heavy residues)". Petcoke is also produced in the production of synthetic crude oil (syncrude) from bitumen extracted from Canada’s oil sands and from Venezuela's Orinoco oil sands.

In petroleum coker units, residual oils from other distillation processes used in petroleum refining are treated at a high temperature and pressure leaving the petcoke after driving off gases and volatiles, and separating off remaining light and heavy oils. These processes are termed "coking processes", and most typically employ chemical engineering plant operations for the specific process of delayed coking.

This coke can either be fuel grade (high in sulfur and metals) or anode grade (low in sulfur and metals). The raw coke directly out of the coker is often referred to as green coke. In this context, "green" means unprocessed. The further processing of green coke by calcining in a rotary kiln removes residual volatile hydrocarbons from the coke. The calcined petroleum coke can be further processed in an anode baking oven to produce anode coke of the desired shape and physical properties. The anodes are mainly used in the aluminium and steel industry.

Petcoke is over 80% carbon and emits 5% to 10% more carbon dioxide (CO2) than coal on a per-unit-of-energy basis when it is burned. As petcoke has a higher energy content, petcoke emits between 30 and 80 percent more CO2 than coal per unit of weight. The difference between coal and coke in CO2 production per unit of energy produced depends upon the moisture in the coal, which increases the CO2 per unit of energy – heat of combustion – and on the volatile hydrocarbons in coal and coke, which decrease the CO2 per unit of energy.
