WORLDKINGS - Worldkings News - Asia Records Institute (ASRI) Hengli Group: The company to operate the world's largest terephthalic acid (PTA) factory


( The new PTA-5 plant has an annual capacity of 2.5 million tons.

The Hengli Group is a Chinese company active in oil refining, petrochemicals, polyesters and textiles. Hengli was founded in Suzhou as a weaving factory in 1994 by husband and wife Chen Jianhua and Fan Hongwei. One of the world's largest companies, Hengli was ranked 67th in the Fortune Global 500 for 2021, and 3rd on a list of China's top 500 Private Enterprises.

Hengli ‘s three subsidiaries are publicly traded Hengli Petrochemical Co., Ltd., Guangdong Songfa Ceramics Co., Ltd., and Suzhou Wujiang Tongli Lake Co., Ltd.

Hengli operates the world's largest terephthalic acid (PTA) factory. Terephthalic acid is an organic compound with formula C6H4(CO2H)2. This white solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles. Several million tons are produced annually.

In 2020, Hengli Petrochemical started up the world's largest stand-alone pure terephthalic acid (PTA) production plant at the end of June. According to PROCESS China, the new PTA-5 plant has an annual capacity of 2.5 million tons and is ready to be the third new plant to be started up in China that year.

Private petrochemical companies in China are currently massively expanding their PTA capacity. If all other projects announced for the rest of the year go on stream as planned, China's total PTA capacity would grow to 69.53 million tons per year in 2020. This represents an increase of 32.6 %.

Hengli Petrochemical's giant PTA plant uses the Invista P8 technology of the American Dupont-ICI group. Using oxidation and hydro-refining, pure terephthalic acid is produced in a two-step process. The process is becoming increasingly popular in China. Out of 21 PTA plants built in China over the past ten years, ten are running Invista processes.
