Tondgooyan Petrochemical Company Output Record (March 2022-2023)

Shahid Tondgooyan Petrochemical Complex in Khuzestan Province increased its output last Iranian year (March 2022-2023) compared to the previous year.

The production of the company reached 1,216,128 tons, which has increased by 105,493 tons in comparison with a year ago, Energy Today website reported.

Tondgooyan Petrochemical Company also successfully indigenized, installed and operated sensitive and critical equipment and machinery at the plant in collaboration with domestic knowledge-based companies.

Launch of the 7th synthetic yarn production line in the textile unit and the localization of the palladium catalyst for the first time are among the other achievements of this company last year.

The palladium catalyst, which was previously monopolized by American, European and Japanese companies, is now produced inside Iran. It is one of the precious metal catalysts used to increase the rate of chemical reaction without itself undergoing any change.

Applications of palladium catalyst include petrochemical, pharmaceutical, automotive, agrochemicals, specialty chemicals, and flavors & fragrances. In the automotive industry, palladium catalyst is used in exhaust emission catalytic converters and diesel particulate filters. It is used to accelerate chemical reactions in manufacturing industries.

Palladium catalysts are used in various catalytic processes, especially in hydrogenation processes. For instance, it is used in the production of hydrogen peroxide from alkylated anthraquinone. Palladium catalyst is used in coupling reactions, wherein two hydrocarbon fragments are coupled with a metal catalyst.

Indigenization in Tondgooyan Petrochemical

The Shahid Tondgooyan Petrochemical Complex has prioritized indigenization of at least 12 catalysts, chemicals, heat transfer fluids, molecular sieves and textile oil to be used in different units of the company during petrochemical processes.

A catalyst speeds up a chemical reaction but is not consumed by it. Most solid catalysts are metals or oxides, sulfides and halides of metallic elements and semi-metallic elements such as boron, aluminum and silicon.

A heat transfer fluid is a gas or liquid that takes part in heat transfer by serving as an intermediary in cooling on one side of a process, transporting and storing thermal energy, and heating on another side of a process.

Heat transfer fluids are used in countless applications and industrial processes requiring heating or cooling, typically in a closed circuit and in continuous cycles.

A molecular sieve is a material with pores of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can.

Molecular sieves are used for drying gases and liquids and for separating molecules on the basis of their sizes and shapes. When two molecules are equally small and can enter the pores, separation is based on the polarity (charge separation) of the molecule, the more polar molecule being preferentially adsorbed.

Textile oil are used for high speed spindles of textile mills and other machine tools where there is a need for antistatic oil with scourable characteristics.

The largest petrochemical producer of PET

Established in 1998, Tondgooyan Petrochemical Company is the largest producer of PET products and pure terephthalic acid in Iran.

In the past two years, more than 10 new PET grades have passed lab tests and entered the market. PET film grade (BoPET films) and PET bottle grade for use in the packaging and food industries are among the recent products of the company.

Another product is a new grade of High Viscose PET, also called engineering polyester yarn. It is used to produce industrial yarns with high strength. The use of engineering polyester yarn includes tire yarn, tarpaulin tents, sturdy fabrics, fishing nets, shipload ropes and conveyors.

The production of crystal PET for use in ovens and microwave containers is also underway. High tenacity polyester will be added to the company’s production soon.

HTPET has the ability to undergo high tension stress and is used as chords in auto tire manufacturing.

The company is striving to gain the technical knowhow to produce more grades of PET.
