In April, the total investment of the ethylene plant of Qilu Petrochemical's olefin plant increased by 6,687 tons compared with the plan, ethylene production increased by 691 tons, propylene production increased by 519 tons, the total output value of products increased by 22.
95 million yuan, the efficiency increase was 15.
2 million yuan, and the average daily efficiency increase was 510,000 yuan.
, which is equivalent to earning back an Audi A6L new energy in one day

Hidden danger: eliminated within 48 hours
Hidden danger: eliminated within 48 hours"There is oil seepage here
.
The two immediately reported the situation step by step
.
"The hidden dangers cannot be discovered and eliminated in time, which will cause the pipeline to rupture and inject fuel at any time, resulting in the shutdown of GB-501, and the production of ethylene will be seriously affected
.
Safety and environmental protection are the basis for tackling tough problems and creating results
.
Subsequently, the factory organized several special inspections and safety inspections of "anti-three violations, risk control, and hidden danger elimination".
Guided by the HSSE management system, the factory fully implemented the main responsibility for safety production, refined and improved the safety and environmental protection work plan, and made a solid and direct The operation link is "trustworthy", which further builds a safety and environmental protection barrier for tackling tough problems and creating benefits
.
Optimization: It is more important to have face
Optimization: It is more important to have face"Collect and sort out all kinds of data from the devices, digitize professional experience, and send out market changes in a timely manner," said Gao Hui, the chief engineer of the production technology department of the olefin plant.
When she goes to work every day, the first thing she does is to check the market conditions and use software to measure the market conditions.
raw materials, output value and marginal benefits, and provide data support for production and operation decisions
.
In April, according to the data of the olefin plant, the input ratio of naphtha in the raw material structure increased by 6.
82 percentage points from the previous month, and the corresponding input ratio of tail oil and light hydrocarbons decreased significantly
.
"Naphtha is cheap now, and the more naphtha is cracked, the more money you can make
.
" Gao Hui's team provides data support for raw material structure optimization from the perspective of maximizing benefits.
For Gao Tongwei, chief of the production technology department, the most important The important thing is how to implement the factory's instructions to realize the efficient operation of the cracking furnace under different raw materials
.
One naphtha cracking furnace was added, one ethane cracking furnace was reduced, and the operation mode of "7 naphtha cracking furnaces + 2 tail oil cracking furnaces + 4 ethane cracking furnaces" was implemented.
best operating mode
.
"Production is an important number that we care about every day
.
" After receiving the production report, Feng Bingkun, director of the cracking workshop, began to discuss with everyone in the WeChat group on the bus.
Why was the production output better yesterday than the day before yesterday? Can production be increased today? Summarize experience, find reasons, and make adjustments at any time
.
"In April, the ethylene unit ate more cheap but relatively poor quality naphtha, resulting in a decrease in the ethylene yield, and the 'face' was not good.
The benefits are significant, and the 'lizi' has become better
.
" Gong Qinyue, manager of the olefin plant and head of the leading chemical plant, said at the recent meeting on tackling difficulties and creating benefits, saying that "lizi" is more important than "face".
Important because this is real money

Indicator: run in a straight line
Indicator: run in a straight lineOn the morning of May 10, in the main control room of the ethylene unit of the olefin plant, Zhang Jian, the deputy squad leader, and his colleagues carefully adjusted the oil temperature of the 501 propylene compressor
.
"Other large units are allowed to have a deviation of 3 degrees Celsius in oil temperature.
In order to stabilize the shaft displacement of GB-501 propylene compressor, the oil temperature deviation is controlled within 0.
5 degrees Celsius
.
" Zhang Jian said that this index they controlled has almost become a straight
.
It is critical to increase the ethylene output and ensure the stable operation of the GB-501 propylene compressor, the core unit of the ethylene plant
.
It has been running for more than 3 years after the maintenance, and the shaft displacement of the compressor has gradually increased.
If the control is not good, the compressor will be difficult to operate normally, and the goal of "two ene" will be lost
.
Oil temperature control is the key to ensuring that its shaft displacement does not increase
.
The olefin factory has set up a special care team to adjust the temperature of the cracking furnace and the amount of oil input in time for the changes in upstream raw materials to ensure that the oil temperature is maintained at 43-44 degrees Celsius and the shaft displacement is within a reasonable range
.
The employees on duty pay close attention to the trend of shaft displacement and temperature changes, record and report them regularly, and immediately send the situation to the “Displacement Special WeChat Group” when they find obvious changes, and the technicians will guide and adjust them in real time according to the on-site situation
.
Through a series of optimization measures, the shaft displacement of the propylene refrigeration compressor GB501 has been effectively controlled
.
At the same time, they also implemented the card edge operation by rationally distributing three sets of cold box loads, oil circuit, steam, process and other systems to keep the SS temperature above 505 °C, and implemented the summer high-load production plan, propylene refrigeration and rectification.
The bottleneck of the system is optimized, adjusted and transformed, and the heat exchanger of the quenching system is cleaned in advance, so that the equipment is always in a healthy state
.
"Tackling fortifications is to face difficulties bravely, think of ways that others have never thought of, and do things that others have never done before
.
" Gong Qinyue inspires everyone every day to fulfill the mission of the leading factory in tackling fortifications and creating results.
First-class, first-class
