Purification process management system reduces unit comprehensive energy consumption by 5.
5%
5%
Sinochem News News As of the end of June, the first domestic purification process management system led by the Puguang Gas Field of Zhongyuan Oilfield has been in operation for 6 months
.
The company's data in the first half of the year showed that the unit's comprehensive energy consumption of the natural gas purification plant was reduced by 5.
5% year-on-year, with a gas saving of 9 million cubic meters and a power saving of 7.
"The system can realize real-time monitoring of the energy consumption of each combined device, with various functions such as abnormal alarms, emergency handling, etc.
, with an accuracy of up to 100%, effectively reducing energy consumption, and significantly improving the level of intelligent management of enterprises
.
" Experts commented this way
.
According to reports, the comprehensive energy consumption of the Puguang Gas Field accounts for more than 70% of the entire oilfield, and the Puguang Natural Gas Purification Plant, which ranks second in the world and No.
1 in Asia, accounts for more than 95% of the energy consumption and is a major energy consumer
.
"The combined device is like a giant ship.
It will only save fuel if it runs at a constant speed within a certain range
"Such a situation often happens
.
In June alone, there were 8 changes
in the production of upstream gas wells in the gas field .
In the past, when it was necessary to adjust the operating parameters of the combined plant, the plant had been using manual methods
.
Technicians must collect a large amount of energy consumption information in a short period of time.
Not only is the accuracy rate low, but the operating effect of the combined device can only be revealed in the comprehensive data after a month
Beginning in 2015, Puguang Branch officially opened the prelude to the "purification process management system"
.
"Over the years, we have explored a lot of data.
The energy saving and consumption reduction methods such as device sleep and hot standby principles are relatively mature
.
These are the main basis for the development of intelligent systems
.
At the end of 2020, after five "milestone" nodes such as data architecture and model conversion, the first domestic purification process management system that integrates production process information visualization and scientific decision-making has officially entered the field trial.
Stage
.
The factory has carried out special training at the factory level, department level, workshop level, and team level.
Special personnel are designated for training on system usage methods, data traceability, problem judgment, etc.
Nowadays, when technicians log into the purification process management system, they not only have a clear view of the actual values of energy consumption indicators such as electric energy, hydrogen energy, and thermal energy, but also can obtain information about where the energy consumption is improved and what methods are used to improve these issues.
Accurate and detailed guidance
.
“Thanks to the application of this system, in the first half of the year alone, the whole plant had 3 indicators hitting the best values in history, which laid a solid foundation for the digital and intelligent transformation and upgrading of the gas field
.
” Said Shang Jianfeng, deputy manager of Puguang Branch
.
It is understood that the factory will continue to expand the system and optimize the database to make the functions more complete and intelligent, and strive to promote it in the field
.
