Ni Dalong: Rooted in hydrocracking units for 24 years

He has been rooted in the hydrocracking unit for 24 years, and has repeatedly eliminated potential safety hazards to protect the device from harm; He has studied hard to operate skills, cultivated excellent skill levels, and won many good results in professional competitions; He is good at integrating theory into practice, exploring optimized operation methods, and improving the economic operation level of
the plant.
He is Ni Dalong
, the leader of the third shift of the hydrogenation joint workshop of the second petroleum plant of Fushun Petrochemical Company.

Grow in practice Insist on "not almost enough"

After returning from the inspection, taking off the hard hat on his head and wiping a forehead covered with fine beads of sweat, Ni Dalong sat in front of the operating table, opened a brand-new notebook, and wrote down the eight words
"dedication to the enterprise and ceaseless running" on the title page.
In the 24 years since he joined the company, he has filled more than 20 notebooks like this, stacked together more than half a meter high, which is his "treasure"
to record his work and study experience.

In 1998, Ni Dalong became a recruit in hydrocracking positions
.
The working conditions of the two reactors of the hydrocracking unit are very harsh, high temperature, high pressure, and hydrogen are extremely
dangerous.
The master often told him that guarding them should be like guarding two "hydrogen bombs" like walking on thin ice, and every operation must be "almost impossible"
.

Ni Dalong is determined to become a person
like his master.
Since then, "almost not at all" has become the yardstick
of his work.
Reading more books, thinking more, and summarizing more have become his habits engraved in his bones, and they are also the secret of his rapid growth into
talents.
Whenever he breaks between work, he will take out his notebook, review the essentials of operation, and think about whether there is a more efficient operation method; When encountering problems, always ask a few more whys, and know why they are
.
When the construction and maintenance of the device began, various equipment disintegrated and unveiled, and the various processes were reconnected, which he regarded as an excellent learning opportunity, day and night in the installation, shuttling between the tower and the tower, "three checks and four determinations", purging and pressure testing, boundary area confirmation and other important links are indispensable
.

In this way, Ni Dalong grew rapidly in the fertile soil of practice, and his skill level became increasingly sophisticated, proving his strength
in various large arenas.
In October 2014, in the technology competition of gas, coal and diesel hydrogenation equipment held by CNPC, Ni Dalong won the gold medal in one fell swoop; In 2017, he won the silver medal in the professional skills competition of team leaders of refining and chemical enterprises of CNPC; In 2021, he won the bronze medal
in the hydrocracking (treatment) unit operator competition again in the national industry vocational skills competition.

Solve production problems Become a useful person for the enterprise

Having cultivated excellent operation skills, Ni Dalong applies exquisite technology to practice, and becomes a useful person
for enterprises by solving production problems.

In November 2015, Ni Dalong made an in-depth analysis of key parameters such as diesel raw material conditions and catalyst activity in the diesel hydrogenation unit, and suggested that the operating conditions should be changed in the case of little change in the composition of raw materials, and the producer country V.
diesel
.
In practice, he and the team members constantly adjusted the operating parameters, analyzed the correspondence between product quality and operating conditions, and finally achieved the goal of diesel quality upgrading by adjusting the reaction temperature alone, and the diesel sulfur content index was less than 10 mg/kg
.

The "card edge operation method" explored by Ni Dalong achieves the most economical operating state
on the basis of ensuring the stable production of the device.
Under normal production conditions, the outlet temperature of the pyrolysis furnace at 345 °C ~ 350 °C can meet the production needs, Ni Dalong led the workers to find ways to control at the lower limit of 345 °C, although only 5 °C difference, but can save a lot of fuel gas, reduce the energy consumption index
of the device.
The temperature control of refined oil products at 60 °C ~ 90 °C can meet the production needs, Ni Dalong led the workers to try to control the upper limit, so that one less air cooler for reducing the oil temperature can be opened, greatly reducing power
consumption.

Inherit the spirit of model workers A group of people run forward together

As a squad leader, Ni Dalong became an important link to inherit the spirit of model workers, and led 17 team members to move
forward together.
In order to quickly improve the technical level of the team staff, he took out his "treasure" book, summarized and condensed the essence content and edited it into an experience compilation for everyone's learning and reference
.

Whenever a new graduate is added to the class, he must take it hand in hand, set plans, goals, and plans, from book theory to on-site operation, from device process to safety emergency disposal, and quickly cultivate one by one technical "masters"
.
Apprentice Miao Huaiyu won the gold medal in the 2020 company technical competition and became the youngest technician in
the workshop.

Demonstration is the best lead
.
Under Ni Dalong's personal practice, the team members worked together
for safe production.
Once, when the team members inspected the hydrocracking diesel air cooler, they found that the flange of the first valve of the outlet circulation line of the diesel air cooler was leaking
.
He immediately reported the leakage at the scene to his superiors and took measures
to connect the oil.
Other members of the team immediately contacted the maintenance to tighten the leakage flange, eliminating the leakage problem and ensuring the safe and stable production of
the device.
