Recently, Hangzhou Hollysys Automation Co., Ltd. (hereinafter referred to as "Hollysys") successfully signed a contract with PetroChina Liaoyang Petrochemical Branch (hereinafter referred to as PetroChina Liaoyang Petrochemical) to construct and rectify 16 sets of control system projects during the planned overhaul in 2023 - 9 sets of triple CCS compressor system + 3 sets of DCS system + 4 sets of GDS system (including AMS and iODS systems), involving a total of 5 branches of PetroChina Liaoyang Petrochemical (refinery, olefin plant, power plants, aromatics plants, thermal power plants).
So far, Hollysys CCS system, SIS system, DCS system, GDS system, AMS system, iODS system of PetroChina Liaoyang Petrochemical Refinery, power plant, aromatics plant, nylon plant, polyester plant, olefin plant, thermal power plant, storage and transportation plant and its Liaoyang Liaohua Yifang Petrochemical Co., Ltd. Yinghua Chemical Plant and other branches have achieved full coverage.
PetroChina Liaoyang Petrochemical is known as the "Republic Seed Team" and "State-owned Enterprise Seed Team", with major production lines such as oil refining, aromatics, olefins, polyester, nylon, etc., 79 sets of refining main production units, 52 sets of auxiliary production units, and a crude oil processing capacity of 10 million tons / year, it is a large-scale petrochemical base featuring aromatics and an important national crude oil processing enterprise in Russia.
The 16 sets of control systems in this transformation involve multi-model control systems of well-known foreign brands, as well as complete sets of PLC systems with air dryers and external liquefaction systems, and some of them also involve the transformation of the old instrument panel into a DCS system. The scattered factory area, the system is miscellaneous, the time to read the source program is tight, the construction period is short, the transformation time is concentrated, and the need to take into account the need to go hand in hand, etc., are the characteristics and difficulties of the system transformation, and the test of the comprehensive strength and service level ability of the winning bidder is a greater test.
As early as 2018, during the last overhaul of PetroChina Liaoyang Petrochemical, Hollysys successfully implemented the transformation of the DCS control system for the 7×410t/h mother-controlled medium-storage pulverized coal furnace of its thermal power plant, achieving a plummeting failure rate of nearly zero, and the boiler combustion optimization to improve quality and efficiency significantly, and the module has been running for more than four years without any damage. Hollysys' excellent project implementation capabilities and excellent product use effects have enabled Hollysys to win the support and trust of the leaders and experts of PetroChina Liaoyang Petrochemical Company, and gave Hollysys the opportunity to participate in the service in depth.
At the beginning of the project, the Shenyang Liaison Office of Hanghe Company conducted all-round communication with users according to the characteristics and needs of the project, and formed a major project team with other departments of the company to create a perfect solution, and finally stood out in the fierce competition and successfully won the bid. After winning the bid, Hollysys quickly carried out design and other related work, and held a meeting with the owner and the design institute to finalize the implementation plan and implementation plan, laying the foundation for the follow-up project set, testing, FAT, etc.
This project is another important breakthrough in the field of control systems for 10 million tons of oil refining enterprises, and has laid a more solid foundation for Hollysys' market development in this field. Hollysys will adhere to the concept of "sincerely envisioning for users", build the project into a high-quality project, eliminate hidden dangers and escort the localization of key equipment and stable production of PetroChina Liaoyang Petrochemical, and help it transform and upgrade from "fuel-based" to "material-based" chemical industry with science and technology!
