In the year named "Production, Support, Removal of barriers"; and for the first time in the petrochemical industry, the control system of "PET ۱" in Shahid Tondgooyan Petrochemical Company has been updated. It was under the monopolization of a company in the USA named Emerson.

According to the Shahid Tondgooyan Petrochemical public relations and international affairs, the operation for upgrading the control system of "PET 1" was implemented in the shortest possible time successfully and without stopping the production. This system belonged to Emerson US and was at the lowest level of efficiency due to the lack of cooperation of the manufacturer, the lack of support from companies producing control and measurement products, besides its obsolescence. So it created fundamental problems in the quantity and quality of production.
In the first step of this project, based on the plans and research, according to them, it The Monopolization of the USA on Petrochemical Industry Broken/ The Control System of was decided to the routine of similar projects, the system program to upgrade it offline within a year. Then, by removing the units from the production circuit, the control system can be implemented and updated.
After completing the program, due to the necessities of Shahid Tondgooyan Petrochemical Company and the vital role of its products in various industries of the country, it was practically impossible to stop all units performing this program. Therefore, to solve this problem by carrying out expert activities besides innovative changes, the possibility of stopping production units was examined and approved separately so that the program does not interfere with the company's obligations to support national production. So, the “POLY C” unit was the first unit due to the need to perform repair work in it, and by stopping it, its control system was updated within seven days and put back in the production circuit.
Having experienced the POLY C implementation program, the idea of ​​operating to update the control system without stopping production was proposed, which made it impossible to inquire from all sources, especially foreign well-known companies. However, due to conducting various meetings and reviewing the details besides the support of the members of the executive team, especially the operation, it was decided to carry out this operation in "POLY B" without stopping production on a trial basis. We are proud to say it was done with the specialists of Shahid Tondgooyan Petrochemical Company in severe weather conditions for 3 hours without any production waste.
The successful implementation of this program in "POLY B" led to the operation of upgrading the control system without stopping production in other units of the PET. Upgrading the production control system in Shahid Tondgooyan Petrochemical Company, in addition to eliminating unwanted stops and other problems of the old system, has brought several benefits such as increased control and process monitoring power, the quantity and quality of products, facilitate the supply of parts and equipment due to their internality.
Shahid Tondgooyan Petrochemical specialists have already succeeded in localizing other parts and equipment of the Polyethylene Terephthalate chain to maintain and continue quantitative and qualitative production, support domestic and self-sufficient production companies, and cut dependence on foreign countries. Design, manufacture, and repair of air supply compressor equipment, manufacture of industrial textile machine keyboard, design, manufacture, and installation of rotary vacuum-drum filter were some efforts of the experts of this company.
