PTA Once Again Usher In PIA Climax

say The first case of PTA's success in converting PIA to production was first thought of the Yanshan petrochemical Limited by Share Ltd. The enterprise was the first to produce PTA products. After the production scale was small, the process and equipment defects were much, material consumption and energy consumption were high. In 1996, Yanshan polyester business division began to study the technology of meta benzene two formic acid. In 1998, the original PTA plant implemented large-scale technical transformation. By August 1998, the transformation work was over, and the PIA product was officially put into operation. At present, Yanshan Petrochemical is domestic. Only PIA production enterprises, production capacity of 50 thousand tons / year.

First: what is PIA ?

Meta phenyl two formic acid Also known as PIA (part IPA), it is a white crystalline powder or needle like crystal. Soluble in alcohol and glacial acetic acid, slightly soluble in boiling water but insoluble in cold water, almost insoluble in benzene and petroleum ether. In industry, xylene was used as raw material, cobalt acetate as catalyst, acetaldehyde as promoter, acetic acid as solvent, at low pressure of 120 0.6MPa. Two benzoic acid was prepared by thermal oxidation. In addition, the oxidation of two benzyl cyanide or the oxidation of meta xylene with Potassium Permanganate is also a method for the production of meta phenyl two formic acid in industry.

PIA It has strong heat resistance, water resistance and chemical resistance. It is used in alkyd resin coatings and polyester. (PET) Resin and unsaturated ( UPR Resins, special fibers, hot-melt adhesives, printing inks, polyester fiber dyeing, plasticizing and medicine are used for prevention.

PIA Status quo: Gundam 85% Import dependence

At present, there is only one Yanshan Petrochemical Company, and its capacity is only in production. Five Around 10000 tons, the total load of the plant is around 90%. Two thousand and eighteen Year in China PIA Import dependence reached 85% 。 And integrated in the past ten years. PIA The total import volume is still showing an obvious upward trend. PIA The huge supply gap in the industry is in the doldrums. PTA The industry has brought a glimmer of dawn, and some enterprises have begun to upgrade their facilities.

Which? PTA Production enterprises are about to switch to production. PIA ?

One , Two thousand and eighteen In August, Jialong petrochemical company plans to transfer 250 thousand tons / year PIA project to the 600 thousand ton / year PTA plant. And the news said: "has entered the detailed design stage, pressure filter, titanium equipment, tower, filter, import instrument and other long term equipment has been ordered to start production, the rest of the ordinary equipment has entered the inquiry and business bargaining stage, pile foundation construction is expected to begin construction in September, steel structure and equipment installation at the end of the year, is expected to enter the installation and commissioning phase in the first quarter of 2019, the second quarter PIA finished products." However, at present, the PTA processing fee is at a high level of 1200 yuan / ton, and the news of conversion has not been clear.

Two The 350 thousand ton / year PTA plant of Yizheng chemical fiber will be converted to PIA. (the revamping of the plant has been completed, and the specific switching production has not yet been determined).

Three In April 3, 2019, Zhejiang Yisheng Petrochemical Co., Ltd. implemented the EIA announcement for the existing PTA two phase production plant to implement the "PTA plant transformation and upgrading technology transformation". The PTA phase two production plant (annual production capacity of 700 thousand tons PTA) will be reformed, using high temperature liquid phase technology to convert 350 thousand tons / year PIA products. The two phase has been installed since 2013. It has been in a state of shutdown.

PIA New installations in the industry

Two thousand and seventeen July Taihua Xingye (Ningbo) Co., Ltd. Newly build The 200 thousand ton PIA project passes the EIA. The project adopts medium temperature oxidation and hydrofining technology. According to long Zhong information, the project will be put into operation in the two quarter of 2019.

PTA Industry status: high cost of processing One thousand and two hundred element / ton

The recent PTA market price is like heaven and hell. It is mainly affected by the collapse of the cost side of PX and the maintenance of its own devices. Judging from the processing fee, as of April 10th, the highest point of PTA processing fee exceeded 1400 yuan / ton this year. According to the processing area of 600 yuan, the profit was as high as 800 yuan / ton. Especially after the tax reduction in April, the PTA processing fee was basically above 1200 yuan / ton. It is not difficult for the industry to question whether the PTA device will be converted at high profit margins.

According to long Zhong information statistics, the new PTA installations in 2019 were only 1 million tons / year installations planned by Sichuan Shengda in May, and the opening of 1 million 500 thousand tons / old installations in Fuhai city. For the fourth quarter of the new Feng Ming 2 million 200 thousand tons / year and constant force four phase 2 million 200 thousand tons / year device uncertainty, or postponed to the beginning of 2020. Even in the four quarter, the impact on the growth rate before the fourth quarter is not large.
