my country’s PTA production capacity is expanding rapidly. The total new production capacity in the next three years will be approximately 25 million tons.

Purified terephthalic acid, referred to as PTA, is an important bulk organic raw material. PTA is an important part of the polyester industry chain. PTA is mainly used to produce polyester fiber, polyester bottle flakes, polyester film and other products, among which polyester fiber production accounts for the highest proportion. PTA is widely used in chemical fiber, electronics, construction, plastics and other fields. In recent years, with economic development and progress in production technology, my country has become a major producer and consumer of PTA in the world.

The mainstream production processes of PTA include low-temperature oxidation process, medium-temperature oxidation process, etc. The PTA production process is to first oxidize para-xylene (PX) to obtain crude terephthalic acid (CTA), and then hydrogenate and refine it to produce PTA. In recent years, due to my country’s high reliance on imports of PX, the development of the PTA industry has been restricted. In order to expand production and meet domestic demand, PTA companies have deployed upstream and downstream of the industrial chain. In 2020, my country’s PTA production capacity equipped with PX will reach 30 million tons. .

According to the “2022-2026 PTA (purified terephthalic acid) industry market in-depth research and investment prospect forecast analysis report” shows that in recent years, my country’s PTA production capacity has expanded rapidly, and my country’s current effective PTA production capacity has reached about 64.8 million tons/year. In 2021, my country’s new PTA equipment will be put into production with 8 million tons, mainly from companies such as Fujian Baihong, Yisheng New Materials, and Shenghong Petrochemical.

my country is a major PTA producer. Domestic PTA manufacturers mainly include Rongsheng Petrochemical, Fujian Baihong, Hengli Petrochemical, Fuhai Chuang, Yisheng Petrochemical, etc. The regional concentration of PTA production capacity is relatively high. At present, my country’s PTA production capacity is mainly concentrated in East China, Northeast China and South China, with the total production capacity of the three major regions accounting for as much as 90%. Judging from the production plans of domestic PTA companies, my country’s PTA production capacity will further increase in the next three years. From 2021 to 2024, the total production capacity of domestic companies planned to be put into production will exceed 25 million tons. The new production capacity is mainly concentrated in Ningbo, Jiangyin, Huizhou and other regions. .

Competition in my country’s PTA market is fierce. In recent years, as environmental protection supervision has become increasingly strict and market competition has intensified, backward PTA production capacity has been gradually introduced to the market, and the PTA market has gradually gathered towards companies with advantages in scale, technology, cost, etc. At this stage, the development level of my country’s PTA industry is relatively high. In the face of fierce market competition, PTA companies still need to increase R&D investment in technical processes, products, PTA wastewater treatment and energy recovery to adapt to the new development trends of the PTA industry under the new situation. Require.

Industry analysts said that as one of the bulk organic raw materials, PTA has a wide range of applications. In recent years, it has benefited from chemical fiber, electronic Demand in other fields is constantly being released, and the PTA industry is developing rapidly. my country is a major country in the production and consumption of PTA, and the regional concentration of PTA production capacity is relatively high. In the future, as relevant production capacity under construction and proposed to be put into operation, my country’s PTA production capacity will be further improved.
