In the past ten years, China's development in chlor-alkali, chemical new materials, polyurethane, pesticides, modern coal chemical industry, nitrogen fertilizer, chemical construction and chemical equipment and other industries

Chlor-alkali: from the scale and speed type to the quality and efficiency type

Since the Eighteenth National Congress of the Communist Party of China, China's chlor-alkali industry has gradually changed its development mode through the effective guidance of industrial policies and the joint efforts of industry enterprises, focusing on industrial structure adjustment, product structure optimization, core competitiveness improvement and product quality upgrading, while paying more attention to technological innovation, energy conservation and carbon reduction, safety management and green environmental protection
.
In terms of enterprise development planning, more attention is also paid to the horizontal coupling and vertical extension of the industrial chain, which has achieved organic combination with petrochemical, modern coal chemical, new chemical materials and other emerging industries, driving the industry from "chlor-alkali power" to "chlor-alkali power"
.

The scale of the industry has shown a rational growth trend, and the benefits have been greatly improved
.
After years of rapid growth in production capacity, since 2013, the chlor-alkali industry has begun a market-oriented de-capacity process
.
Especially during the "13th Five-Year Plan" period, under the guidance of the national supply-side structural reform policy and the joint efforts of enterprises, the growth rate of the industry's leading product production capacity slowed down and entered the stage of
rational growth.
In 2021, there will be 159 caustic soda production enterprises in China, with a total production capacity of 45.
08 million tons.

There are 71 polyvinyl chloride production enterprises with a total production capacity of 27.
13 million tons
.
The market supply and demand are basically balanced, the product structure is continuously optimized, and the benefits of the chlor-alkali industry are significantly improved
.

Pay attention to technological innovation, leading product technology and equipment level continues to improve
.
In recent years, China's caustic soda production technology and equipment continue to make progress, the current enterprises basically all use ion membrane electrolysis technology and equipment, membrane pole distance transformation has been completed more than 90%, in the world-class level
.
With the maturity of localized ion membrane products and the continuous expansion of applications, the localization capacity of production equipment in the industry has been continuously improved, and the equipment level is at the world's advanced level
.

In-depth exploration of clean processes, "three wastes" emissions have been greatly reduced
.
Around the maximization of waste and resource utilization, the industry has carried out a large number of technical research and practice, and a number of new processes and new technologies have been industrially applied
to the technology of calcium oxide made of calcium oxide from calcium carbide slag, polyvinyl chloride (PVC) polymerization mother liquor water reuse polymerization process technology, and the advanced treatment technology of mercury-containing wastewater.
With the research and development and application of technology and process, the continuous chloroacetic acid process, the acid-phase suspension chlorinated polyethylene (CPE) process, the aqueous method chlorinated polyvinyl chloride (CPVC) process, and the glycerol method epichlorohydrin process have been widely used, the product quality has been steadily improved, the "three wastes" emissions have been greatly reduced, and the proportion of new process production capacity has increased
significantly.

Increase investment and promote the intelligent development
of industry informatization.
Chlor-alkali enterprises have increased investment, adding a large number of new elements to the traditional manufacturing industry, and digitalization and intelligence have become a new engine
for enterprise development.
In August 2020, on the basis of building a smart factory, Yibin Tianyuan Group kicked off the construction of an ecological platform for the whole industry chain of the industrial Internet in the chlor-alkali industry
.

The level of energy-saving safety and environmental protection has continued to improve, and "front-runners" have continued to emerge
.
Chlor-alkali enterprises strictly implement the national requirements on product energy consumption, comprehensively improve the level of energy efficiency, and the "frontrunners" of energy conservation and water conservation continue to emerge
.
In 2021, the comprehensive energy consumption of the four caustic soda energy efficiency "frontrunners" enterprises, Qingdao Haiwan Chemical Co.
, Ltd.
, Binhua Group, Zhejiang Zhenyang Development Co.
, Ltd.
, and Wanhua Chemical (Ningbo) Chlor-alkali Co.
, Ltd.
are all better than the industry energy efficiency benchmarking level
.
In July 2020, Beiyuan Group cooperated with a Shanghai enterprise to tackle the mixed solvent glycine pilot plant to start construction, filling the gap of similar technologies in China
.
This technology effectively solves the problems
of large amount of wastewater generated by the traditional chloroacetic acid aqueous method, high energy consumption and high cost.

Actively combine with the new energy industry, and strive to change from "energy consumption" to "energy generation
".
Chlor-alkali enterprises pay great attention to the development trend of clean energy such as photovoltaics, hydroelectric energy, wind energy, hydrogen energy, etc.
, study and promote the application of new energy in the industry, and lay a solid foundation
for the industry to implement the "double carbon" strategy.
Many key backbone enterprises have explored the power consumption end of the industry, planning to use intelligent ecological photovoltaic and modern coal chemical industry to combine to try to greatly reduce the energy consumption level and total emission of
new projects.
At the same time, many backbone enterprises continue to improve the comprehensive utilization level of their hydrogen energy, keep up with the development trend of hydrogen energy, actively participate in the construction of regional hydrogen energy infrastructure, lay out the industrial chain around hydrogen energy, cultivate new profit growth points, and strive to achieve the transformation
from "energy consumption" to "energy generation".

Expand international influence, and the pace of "going out" is constantly increasing
.
In the past ten years, the chlor-alkali industry has made certain progress in product trade, equipment manufacturing, technical services, etc.
, and the internationalization ability of the industry has been continuously improved
.
In recent years, domestic chlor-alkali products have been exported to more than 100 countries and regions, and the number of products exported to India, Southeast Asia, Australia, Africa and other places has been increasing, and the pace of industry internationalization is accelerating
.

in the development of the industry.
Taking the pressure vessel manufacturing industry as an example, the first is reflected in the digitization of the manufacturing process, such as through the non-conformance report (NCR) control, to ensure the stability of the quality controllable program, and to provide data support
for the next step of visualization.
The second is the intelligence of manufacturing, such as intelligent welding technology in recent years in the equipment manufacturing industry has become a fashionable technology, can ensure that the welding quality is controllable
.
In addition, many equipment manufacturing enterprises are still paying attention to the visualization of the manufacturing process, that is, each link of the production process is open to the user, and the user has the right to log on to the network to understand the specific conditions of each order, so as to obtain a great sense of trust from
the user.

Digitalization makes chemical equipment more stable
