Recently, the chemical center control room was successfully put into use

Maoming Petrochemical completed the chemical center control room

Instrument Relocation Project

9 sets of device control systems realized localization

The first large-scale ethylene cracker in China

The localization transformation of the control system was successful

The relocation project of the chemical central control room under the responsibility of the instrument control and measurement department took only 27 days, 8 days ahead of the original plan.
The relocation, commissioning and upgrading of 52 sets of systems were completed, and the centralized control of the production operations of 17 sets of main production units was improved.

The new chemical center control room

There are 9 DCS control rooms in the chemical plant, and the control rooms of each device have always been scattered, which is not conducive to the communication between the upper and lower processes, and the management and production scheduling are difficult

The new chemical center control room covers an area of 4461.
48 square meters, which can accommodate 50 sets of main devices, 75 sets of centralized control of system production operations, and supporting functional rooms such as engineer station, cabinet room, UPS room, and air conditioning room

The employees carefully monitor the disk in the new central control

The completion and commissioning of the chemical center control room realized that a central control room adopts advanced means of integrating management, control and operation, which provides an information and automation foundation for the implementation of the company's "14th Five-Year Plan", and consolidates the company's construction of a smart factory.
foundation

For the domestic transformation of the first large-scale ethylene cracker control system in China, the friends of the Maoming Petrochemical Instrument Control and Measurement Department have made a lot of efforts!

Conduct cloud training

As early as after the Spring Festival in 2020, the cadres and employees of the Instrument and Accounting Department entered a tense "wartime state"

A large number of breakthroughs

In the system relocation project, they need to dismantle 103 cabinets and install 127 cabinets, involving 40,258 instrument points, 201,290 tightening terminals, 329 kilometers of cables in the cabinet, 322,064 configuration parameters, and 120,774 joint debugging instruments.
Debugging 12,280 control loops took 35 days to complete according to the overall requirements, and the task was very heavy

Team is busy

The company's instrumentation experts, members of the instrumentation department, directors of various management offices, and professional engineers went down to the first level to fully promote the relocation
.
Due to the lack of strength, they dispatched more than 40 technical backbones from the oil refining instrument operation area to come to support
.
Party members and cadres at all levels and front-line employees live on site, work overtime, and volunteer 32,000 hours
.

Work overtime

Break the "foreign monopoly"

During the system relocation process, the localization transformation of the control system of No.
2 cracking unit is the highlight
.
In the absence of any experience to follow, they carried forward the spirit of petroleum and iron man, and established a research team to carry out technical research.
After 27 days of day and night debugging, they successfully transformed the device control system into a localized control system.
, breaking the "monopoly" of maintenance technology
.

There are three major advantages after the localization of the control system
.

01.
The supply of spare parts for the control system can be optimized, breaking the dilemma that key devices and key equipment are monopolized by foreign technologies and markets

02.
After the transformation, the RTO system will be put into use normally, and the combination of device loop control and process operation optimization will lay the foundation for maximizing the benefits of the device

03.
The operation design and configuration method of the localized control system after the transformation is more in line with the operating habits of the operators than the imported system, and the interface is in Chinese, which is convenient for daily operation and maintenance, and effectively prevents misoperation
.

After the transformation, the operation design and configuration method of the localized control system are more suitable for the operating habits of the operators than the imported system, and the interface is in Chinese, which is convenient for daily operation and maintenance, and effectively prevents misoperation
.

At the same time, the other 8 sets of control systems of the chemical division have also achieved localization transformation
.
