Wang Xiaojuan: An expert in the operation of the coking workshop

In the past 15 years, she has been sticking to the operation post of delayed coking unit in Yumen Oilfield Refining and Chemical General Plant, and ensured the smooth completion of various tasks by smoothly controlling the "central nerve" of coking, so that the qualification rate of various process indicators and product quality reached 100%, the smooth operation rate reached more than 99%, the thermal efficiency of the heating furnace was maintained at more than 92%, and also created the highest record
of 602 days of continuous and safe operation of the single furnace of the heating furnace.
She is Wang Xiaojuan, the front-line operator of the delayed coking unit of the
Yumen Oilfield Refining and Chemical General Plant.

When she first joined the work, Wang Xiaojuan, who did not know anything about oil refining, was very troubled
by the large and small equipment in the device and the pipeline process crisscrossing like a spider's web.
But she did not give up, but secretly determined not only to humbly consult experienced masters on the principle and operation process of delayed coking production, but also to fully understand the performance of
the equipment.
She mastered the ins and outs of each pipeline process as quickly as possible, and became familiar with hundreds of process parameters
.

"Facing the complicated work every day with full enthusiasm and responsibility is what I must do
.
" With this work belief, she has collected nearly 1,000 data displayed by 20 real-time monitoring screens in the main control room and 12 operation interfaces on DCS
.
The bright furnace and neat flame, the process record with clear handwriting and zero errors, the smooth process data operation trend, and the 100% product quality pass rate are the answers that Wang Xiaojuan handed over to assess her work ability
.

Wang Xiaojuan has a black notebook, she records the problems encountered and the solutions one by one, and slowly accumulates into a "small encyclopedia" of coking operations, which she takes out as soon as she has time to flip through and strengthen her memory
.
In order to facilitate the process and numbering of memory devices, Wang Xiaojuan and her colleagues brainstormed and created the "Absorption Stable 28 Memory Method", and drew a set of three-dimensional flow charts that were completely consistent with the scene for everyone to exchange and learn
.
As the main operator of the coking workshop, she leads by example and leads everyone to optimize the operation and ensure that the indicators of the monthly team are among the best
.

The 500,000 tons/year delayed coking unit is about to open the plant, and the continuous struggle of "5+2" and "white + black" has made Wang Xiaojuan quickly become a down-to-earth, studious, diligent, dedicated and dedicated device to run smoothly
.
During the critical period of the transformation and upgrading of new and old coking, Wang Xiaojuan, as a member of the coking workshop, braved the cold, drilled the trench, went to the tower, ran the site, added blind boards and school instruments outdoors at -20 °C, her fingers were frozen wood, and her feet were numb, but she did not flinch and completed the task
brilliantly.

During a night shift, Wang Xiaojuan found that the liquid level of the V102 buffer tank fluctuated in a large range, and the liquid level sometimes directly showed zero, which would cause the radiation pump to evacuate and the radiation feed of the heating furnace to be interrupted, thereby causing the furnace tube to coke
.
With the experience she usually accumulated, she quickly judged that the liquid level fluctuation was caused by the failure of the control valve, and immediately coordinated the external patrol to adjust the upper and lower flow valves at the fractionation column platform, which avoided a furnace tube coking incident
due to timely processing.

There are many things like this, and Wang Xiaojuan solves
them one by one with her superb skills.
In her eyes, the interlaced pipelines, towering towers, and sophisticated equipment of the coking device are more like "children" who need careful care, and she has become familiar with the "temper" of each equipment and understand the smooth operation of
the device.
