"One size fits all" makes enterprises "not enough to eat"!

Since the beginning of this year, the "dual control" of energy consumption in some parts of our country has been too vigorous, which has doubled the pressure on coal chemical companies and is at a loss
.
The author believes that some localities do not distinguish between fuel coal and raw coal used by coal chemical companies.

At present, this simple method of determining coal consumption indicators for actual energy consumption over the past year is unreasonable
.
According to the author's understanding, the coal consumption quotas issued to coal chemical companies in some parts of China in 2021 will be reduced by a certain percentage based on the actual consumption of the company in the previous year

Therefore, the coal consumption of coal chemical companies in 2020 is generally much lower than in normal years
.
On the basis of this, the local government is unscientific to assign the total energy consumption for this year to the enterprises, which makes the enterprises feel that they are slashing their feet and fitting their shoes, which does not meet the actual production needs of the enterprises

For example, in the first quarter of last year, a coal-to-liquid company was affected by the epidemic and basically had no production and its energy consumption base was small.
The local government required the company to reduce its total energy consumption in the first quarter of this year by another 50,000 tons of standard coal year-on-year

The encounters of these two companies are not alone, and it is not just individual places that operate in this way
.
During the "13th Five-Year Plan" period, some provinces and regions failed to complete the national energy consumption "dual control" indicator task, and some were interviewed and notified because of their low rankings

In some provinces, from the province to the city and county to the enterprise, the energy consumption "dual control" indicators are broken down level by level
.
The result of layer-by-layer transmission is that, in order to be able to "intersect" with the above, the local government has adopted this "one size fits all" approach, which has harmed both enterprises and local economies

The operation of any enterprise has its own economic laws
.
If the output of an enterprise is too low in the production process, the cost of the product will inevitably be high, and the loss will be certain; if the enterprise loses money for a long time, the closure is certain; if the enterprise closes more, the local economy will be affected to a certain extent

The correct way to "dual control" energy consumption is to reasonably deduct raw coal from the total energy consumption
.
Coal chemical industry is the process of converting raw coal into new energy forms such as methanol, oil, natural gas, polypropylene and carbon-containing chemicals.
During this process, only a small amount of energy is emitted during the production process, while the energy consumption of coal chemical industry mainly occurs in Fuel coal

Therefore, it is necessary to distinguish these two types of coal with different functions and adopt different accounting standards
.
However, due to the lack and imperfection of relevant national standards, local governments often confuse fuel coal and raw coal in the actual implementation process, and all raw coal is included in energy consumption
.

Take coal to olefins as an example.
At present, there is no energy consumption accounting standard for the whole process of preparing polypropylene products from coal-based olefins.
In some places, fuel coal and raw coal are used as physical energy input for accounting only according to the "National Statistical Report System".
, Ethylene, propylene, methanol, polypropylene and other carbon-containing chemicals have not been reduced as the physical output of energy, resulting in deviations in comprehensive energy consumption accounting
.

In fact, there are two national standards for the comprehensive accounting of coal chemical industry, namely "Coal to Olefins Unit Product Energy Consumption Quota" (GB30180-2013) and "Polypropylene Unit Product Energy Consumption Quota" (GB31826-2015).
The standard separately calculates the comprehensive energy consumption of the raw coal to olefin section and the comprehensive energy consumption of the olefin synthesis to polypropylene section
.
Unfortunately, the current local government has not calculated energy consumption indicators for coal-based polypropylene enterprises in accordance with these two scientific and reasonable standards, which has led to substantial reductions in energy consumption indicators for related enterprises
.

This is not only the case for coal-to-olefin companies, but coal chemical companies with other process paths are also facing the same dilemma
.

Green factory "grows" brilliantlyThe construction of Shanxi Xiangyuan's 1.
01 million tons of modern coal chemical project is progressing smoothly

Meng Xia’s Qinyuan is full of greenery and full of vitality
.

Walk into the construction site of Shanxi Xiangyuan New Coal Chemical Co.
, Ltd.
, which is located in the Qinyuan Economic and Technological Development Zone.
The 1.
01 million tons/year modern coal chemical project construction site covers an area of ​​about 659 acres.
Bulldozers, rammers, cranes, Concrete pump trucks and other machinery are under intense work
.

Towering chimneys, tower cranes, vehicles passing by and crowds of people, exposed loess are all covered with green nets and "green outfits", dots and lines, movement and stillness are perfectly combined here, intertwined into a picture of construction in full swing
.

At the construction site, two tall coke ovens resisted the wall, and steel bars stood upright, erecting an arched blue greenhouse
.

"This is the fully enclosed greenhouse that we have invested more than 30 million yuan to build the coke oven body in the Changzhi area, which is equivalent to adding a cover to the coke oven to recover all the flue gas waste heat generated after coking, and the chimney is no longer white smoke, smoke from the traditional coal enterprises 'fugitive emissions' all change 'organized emissions', to achieve green production
.
"Shanxi Xiang source of new coal chemical Managing Yanjun Hu said
.

"Choosing to land in Qinyuan, on the one hand, is because of the superior business environment here, on the other hand, the natural ecological environment here also deeply attracts us
.
In the green Qinyuan, we must go green, so When we build green factories and green factories, we must not destroy the
" green sea " in front of us .
"

The installation of a fully enclosed greenhouse for the coke oven body is just one of the measures taken by Shanxi Xiangyuan New Coal Chemical Co.
, Ltd.
for energy conservation, emission reduction, and transformation and development
.
As a key project in the city, the 1.
01 million tons/year modern coal chemical project has a total investment of 1.
84 billion yuan.
The first phase of the project mainly builds (2×50 holes) 1.
01 million tons/year carbonization chamber with a height of 6.
05 meters for tamping large-scale coking, and supporting 70,000 tons.
Ton/year LNG new coal chemical project
.
Supporting the construction of equipment coal system, double dry coke quenching device, waste heat power generation system, chemical production recovery and purification device, LNG supporting facilities, flue gas desulfurization and denitrification and other public auxiliary projects and environmental protection facilities
.

Speaking of coal coking enterprises, people generally think of them as plant buildings, chimneys smoking, waste water flowing across, and serious pollution.
Coal coking is synonymous with "dirty, messy, and dirty"
.

However, the green factories that are currently "growing" will overturn people's previous impressions when they are put into operation and achieve results
.
Shanxi Xiangyuan New Coal Chemical Co.
, Ltd.
follows the positioning of "high-end, intelligent, green, and integrated", adheres to the standards of "first-class equipment, first-class environmental protection, and first-class quality", promotes comprehensive innovation in technology, products, management and systems, and explores energy conservation Potential, committed to creating a "new model for coking transformation and upgrading
.
"

The "Four Big Vehicles" of coal loading truck, coke pushing truck, coke blocking truck and quenching truck adopt advanced German technology to realize intelligent production of "manned and unmanned operation"
.
The coke oven adopts technologies such as furnace body exhaust gas circulation, segmented combustion heating, and external flue gas forced recirculation to further reduce the original NOx emission and the recovery and utilization of low-grade flue gas waste heat
.

The investment of 140 million yuan is the first to build a standby dry coke quenching device in the province, which is another highlight of the 1.
01 million tons/year modern coal chemical project
.
Compared with the most traditional coke quenching method-wet coke quenching, dry coke quenching is a major energy-saving and environmentally friendly technology in the iron and steel industry.
It can improve the quality of coke, avoid the environmental pollution of wet coke quenching, and recover the sensible heat of red coke.
, Can play the dual role of energy saving and environmental protection
.

Dry quenching has many advantages, but the construction cost and operating cost of the dry quenching tower are high
.
The 1.
01 million tons/year modern coal chemical project not only introduced dry quenching technology, but also built a standby dry quenching device, that is, two sets of dry quenching devices were built
.

"Under normal circumstances, in order to control costs, coal coking companies will deploy at most two sets of coke
quenching devices, 'one dry and one wet' .
However, we have built two dry quenching devices.
The construction cost and operating cost have obviously increased exponentially, but this Even if one set of dry quenching equipment needs to be overhauled, another set of dry quenching equipment can be used to avoid environmental pollution
.
" Introducing the project, "post-80s" Yin Junhu seemed to be an experienced coking expert
.

The application of SDS dry desulfurization and denitrification advanced and mature process equipment continuously reduces pollutant emissions and reaches the international advanced level
.
Industrial wastewater is deeply treated and reused, water resources are fully recycled, and three-effect evaporation technology is adopted to completely achieve zero discharge
.

After the project is put into operation, it can produce 1.
01 million tons of coke, 52,000 tons of tar, 13,000 tons of crude benzene, 12,000 tons of ammonium sulfate, and 70,000 tons of LNG.
It is estimated that the annual output value can reach 2.
8 billion yuan, and the profit and tax will be about 500 million yuan.
, Which can solve the employment problem of more than 1,000 local people
.

Being proficient in the main business, doing well in the sideline business, and diversified development, the new coal chemical industry chain is getting longer and longer, and a green and low-carbon benchmarking company is growing vigorously!
