Tomskneftekhim has introduced automation of PP and PE production

February 12/2020

MOSCOW (MRC) - Tomskneftekhim (TNKhZ), a subsidiary of SIBUR and one of the largest Russian producers of polymers - polypropylene (PP) and high-pressure polyethylene (LDPE), has introduced an advanced process control system APC (Advanced Process Control) at key installations of polypropylene and polyethylene production, the press service of the Tomsk site of SIBUR reported.

This is a hardware-software complex for process control, based on modeling methods and predictive control. The system is superstructured over the already existing automated process control system (APCS) and allows, based on given mathematical models, to maintain a stable technological mode.

The introduction of the control system for polymer production at Tomskneftekhim leads to a decrease in energy consumption and raw material consumption, an increase in environmental performance of plants, an increase in plant productivity, and stabilization of product quality.

The control system is associated with minimizing the information load on operators controlling the process.
In 2020, a new system was commissioned at Tomskneftekhim to control processes such as polymerization of propylene, regeneration of the solvent in the production of polypropylene, compression and polymerization of ethylene, and granulation of polyethylene.

"Implementing APC is a successful global practice for managing complex processes. Unlike other systems that regulate each parameter separately without controlling their influence on each other, the control system defines a working algorithm, calculating and considering the dependence of the parameters in advance. An improved system allows us to optimize the process and significantly improve the technical and economic performance indicators of production, explained Konstantin Koryakin, deputy chief production engineer at Tomskneftekhim.

It is predicted that the economic effect of the introduction of process control systems at the polymer production of Tomskneftekhim during the year will be 69 million rubles. due to the additional release of polyethylene and polypropylene and reduction of energy resources.

The SUUTP, which was introduced in 2019 at the gas separation unit for the production of monomers of Tomskneftekhim, already allows increasing the efficiency of the enterprise by increasing the yield of target products and reducing the volume of recycle streams leaving the gas separation columns. The annual effect will be 21 million rubles.

The project for the implementation of advanced process control systems is being deployed at most SIBUR enterprises.

Tomskneftekhim is the first enterprise where the implementation of the control system is completed at the main production facilities.

According to the ICIS-MRC Price Report, in September 2019 Tomskneftekhim stopped production for scheduled preventive repairs.

Tomskneftekhim, LLC, was established in July 2003 on the basis of Tomsk enterprises - CJSC "Metanol", OJSC "Plant Benzol", OJSC "Tomsk Petrochemical Plant", OJSC "Tomsk Petrochemical Enterprise". Tomskneftekhim is a subsidiary of SIBUR and one of the largest Russian producers of polymers - PP and LDPE. The capacity for Tomskneftekhim's production of LDPE is 240,000 tonnes/year and production of PP - 140,000 tonnes/year.
