Recently, Hangzhou Hollysys Automation Co., LTD. (hereinafter referred to as Hanghe Company) successfully signed a contract with Liaoyang Petrochemical Branch of China National Petroleum Company Limited (hereinafter referred to as: 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 system), It involves 5 branches of petrochina Liaoyang Petrochemical (refinery, olefins plant, power plant, aromatics plant, thermal power plant).

At this point, Hollysys CCS system, SIS system, DCS system, GDS system, AMS system and iODS system have been fully covered in petrochina Liaoyang Petrochemical Refinery, power plant, aromatics plant, nylon plant, polyester plant, olefin plant, thermal power plant, storage and transportation plant and its subsidiary Liaoyang Liaohua Yifang Petrochemical Co., LTD. Yinghua Chemical Plant.

Known as the “seed team of the Republic of China” and “seed team of State-owned enterprises”, petrochina Liaoyang Petrochemical Co., Ltd. has major production lines for oil refining, aromatics, olefin, polyester and nylon, 79 sets of main refining and chemical production units, 52 sets of auxiliary production units, and a crude oil processing capacity of 10 million tons/year. It is a large petrochemical base characterized by aromatics and an important Russian crude oil processing enterprise.

The transformation of 16 sets of control systems, involving foreign well-known brands of multi-model control systems, as well as with the air dryer complete sets, with the foreign liquefaction system complete sets of PLC system, some also involved the old instrument panel transformation into DCS system. Scattered plant area, miscellaneous system, tight reading source program time, short construction period, concentrated transformation time, the need to take into account and go hand in hand, etc., are the characteristics and difficulties of the system transformation, which is a greater test for the comprehensive strength and service level ability of the winning manufacturer.

As early as 2018, during the last overhaul of petrochina Liaoyang Petrochemical, Hollysys successfully implemented the DCS control system transformation for the 7×410t/h master pipe medium storage pulverized coal furnace of its thermal power plant, achieving a linear decline in the failure rate close to zero, boiler combustion optimization, quality and efficiency improvement and other effects, and there was no damage to the module for more than four years of operation. With excellent engineering implementation ability and excellent product use effect, Hollysys has won the support and trust of the leaders and experts of petrochina Liaoyang Petrochemical Company, giving Hollysys the opportunity to participate deeply in the service.

At the beginning of the project, Hanghe Shenyang Liaison Office conducted all-round communication with users according to the characteristics and needs of the project, and formed a major project team together 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, Li Shi quickly carried out design and other related work, and held a groundbreaking meeting with the owner and the design institute to finalize the implementation plan and implementation plan, laying the foundation for the follow-up project sets, testing, FAT, etc.

This project is another important breakthrough for Hollysys 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 uphold the concept of “sincerely envisiving for users”, build the project into a high-quality project, eliminate hidden dangers for the localization and stable production of key equipment of petrochina Liaoyang Petrochemical, escort it, and transform and upgrade from refining “fuel type” to chemical “material type” with science and technology!
