Chlor alkali enterprises in Western China seek breakthrough in adversity

wallpapers News 2020-11-17

With the cost advantage, chlor alkali enterprises in Western China have become an important force in chlor alkali industry.

However, due to the serious overcapacity, the production operation of chlor alkali enterprises in Western China have also encountered varying degrees of difficulties.

According to the interview of China chemical industry news, many western enterprises actively adjust their products industrial structure, extend the industrial chain, develop circular economy, develop high-end products, actively seek breakthrough in the market predicament.

At present, the chlor alkali industry is still facing the problem of overcapacity.

How to solve the problem of capacity transformation development has become the primary problem to be solved by enterprises.

Guan Gang, general manager of Xinjiang Tianye Co., Ltd., said that on the basis of building improving the industrial chain of calcium carbide process PVC circular economy, Tianye decided to further exp the scale of using calcium carbide furnace tail gas to produce high-end chemicals.

In 2013, it started the construction of 170000 T / a 1,4-butanediol 200000 t / a ethylene glycol projects, which are planned to be put into operation by the end of this year.

By then, Tianye Group will form a production scale of 200000 tons / year of 1,4-butanediol 250000 tons / year of ethylene glycol.

"There is no successful precedent at home abroad in the production of ethylene glycol from calcium carbide furnace tail gas.

Through effective integration, the industrial test of producing ethylene glycol from carbide furnace tail gas of 50000 tons / year has been successful.

At present, the plant has been running at full load, the economic technical indexes have reached or even exceeded the expected targets.

On this basis, we have built a 200000 t / a ethylene glycol plant, the construction progress is on schedule.

The commissioning of 1,4-butanediol ethylene glycol projects is a lmark event in Tianye Group's restructuring transformation mode.

" Guan Gang said.

As a leading enterprise in the chlor alkali industry in China, Xinjiang Zhongtai (Group) Co., Ltd. took the lead in breaking through by actively adjusting the industrial layout, promoting industrial transformation upgrading.

Relying on the traditional chlor alkali industry, Zhongtai group has strengthened the adjustment of industrial layout, actively carried out PTA project construction with PetroChina, restructured assets with Zhejiang Fulida Co., Ltd., cooperated with local private enterprises to produce promote high-grade plastic steel doors windows.

"The company has successively strengthened strategic cooperation with Xinjiang Fulida, Meihua monosodium glutamate other downstream customers in Xinjiang, the daily sales volume of liquid caustic soda is more than 700 tons.

In particular, through restructuring increasing capital to support Xinjiang Fulida to exp its scale, China Thail achieved exclusive supply, the annual sales volume of liquid caustic soda increased from 200000 tons to 250000 tons.

By signing a strategic cooperation agreement with Meihua monosodium glutamate, the sales volume of liquid caustic soda increased from 10000 tons / year last year to 20000 tons / year.

" Xinjiang China Thail related responsible person told China Chemical News reporter.

"In the first quarter, most enterprises in the chlor alkali industry in China suffered losses, even some enterprises in the eastern part of the country stopped production or half stopped production.

PVC resin ion-exchange membrane caustic soda respectively completed 25.

9% 26.

0% of the annual plan, with a year-on-year growth of 14.

0% 10.2%. the cumulative power generation of 2.

187 billion kwh, a year-on-year increase of 26.7%. calcium carbide production completed 27.

2% of the annual plan, with a year-on-year increase of 33.9%. ”Xinjiang China Thail relevant person in charge said.

The development of circular economy is a bright spot in the development of chlor alkali enterprises in Western China.

Many enterprises have formed their own characteristics in circular economy.

According to the person in charge of Xinjiang Yihua Chemical Co., Ltd., in terms of circular economy, the enterprise relies on the rich resources of Xinjiang For coal, natural gas, lake salt, limestone other resources, the strategy of multi industry symbiosis coupling local transformation of resources is implemented.

In the fields of mining, coal chemical industry, natural gas chemical industry, salt chemical industry, thermal power, fine chemical industry, machinery manufacturing other fields, the strategy of local resource conversion will be implemented according to the sustainable development mode of circular economy to form a relatively complete industrial chain.

In addition, the enterprise has also realized the diversification of product structure, including caustic soda, PVC, synthetic ammonia, urea, other fine chemical products cement, etc.

the products of several industrial chains are used mutually, there is no waste discharge.

In the PVC circular industrial chain project invested by Ordos Junzheng Energy Chemical Co., Ltd., the annual output of 300000 tons of PVC supporting 500000 tons of calcium carbide project has entered the trial production stage in November last year.

"The company will further give play to the competitive advantage of the integration of circular economy, improve the comprehensive utilization capacity conversion efficiency of resources, ensure the stable operation of main devices, actively promote the application of automation informatization in production, strengthen the fine management, effectively reduce the purchase cost, material consumption period cost, so as to reduce the unit cost.

" The relevant person in charge of the enterprise said.

Inner Mongolia Yule chemical company invested 10.

3 billion yuan to build the chlor alkali chemical circular economy project, forming a coal gangue power generation calcium carbide caustic soda PVC cement chlor alkali chemical industry cycle chain.

The chlor alkali chemical recycling economic project is divided into two phases, of which the investment in the first phase is 6 billion yuan, the investment in the second phase is 4.

3 billion yuan.

The main projects include an annual output of 500000 tons of PVC, 500000 tons of caustic soda, 750000 tons of calcium carbide, 2 × 35 MW Circulating fluidized bed boiler air cooling unit project, 500000 tons of lime, 700000 tons of blue carbon, 2 × 25000 tons of ferrosilicon, 2 million tons of cement, etc.

, forming a relatively complete circular industrial chain, so that all the waste in the production process can be comprehensively utilized.

At present, there is a surplus of general-purpose chlor alkali products in China, but many high-end products have to rely on imports.

In view of this situation, many chlor alkali enterprises began to produce high-end br PVC resin.

Zhang xiongtang, deputy general manager of Shaanxi Beiyuan Chemical Group Co., Ltd., told China chemical news that they were eliminating 100000 tons / year diaphragm caustic soda accelerating transformation upgrading.

"For western enterprises, the production capacity of caustic soda PVC is already in excess, so we do not intend to exp the capacity of caustic soda at present.

We just want to make some high-end special br PVC products on the basis of the original million ton caustic soda PVC project, so as to exp the market share of high-end products.

" Zhang xiongtang said.

According to reports, at present, Beiyuan chemical is working out a transformation upgrading plan.

"Cable material is a way of thinking, the next step is to do high degree of polymerization resin matting resin, exp the relevant market.

At present, the polymerization degree of general-purpose PVC resin is only about 1000.

What we need to do is high polymerization degree PVC resin with polymerization degree of 2000-2500.

It is mainly used to produce high-end soft products transparent products with similar rubber elasticity, so as to improve the added value of the products.

Japan has more than 100 brs of PVC resin, mainly to take a high value-added production line, this is our development direction.

" Zhang xiongtang said.

Zhang xiongtang said that due to the small application market dem of domestic special special resins, the resin brs produced by the enterprises in the future will still be general-purpose, striving to achieve diversification adjusting at any time according to the market situation.

"One of the reasons for the predicament of chlor alkali industry is the overcapacity caused by disorderly expansion, many common brs, serious homogenization insufficient innovation capacity.

Therefore, we are also speeding up the adjustment of product structure.

From the release of enterprise stards for PVC resin special materials vinyl chloride monomer in February, then to the first research report on product quality improvement issued by enterprises in March, a series of measures related to product quality improvement, such as multi model, multi batch directional freight transportation of Zhongtai group, have been gradually launched.

" Xinjiang China Thail relevant person in charge said.

At present, the largest production sales volume of Ningxia Yingli Chemical Co., Ltd. are PVC resin caustic soda, with annual production capacity of 260000 tons 210000 tons respectively.

In 2014, the company plans to produce 465000 tons of calcium carbide, 27000 tons of PVC, 195000 tons of 32% alkali 100000 tons of 48% ion-exchange membrane alkali.

Hu zhong, general manager of INET, said recently that the company's future business growth point is to improve the integrated industrial chain, adjust the PVC product structure, develop different types of PVC products, vigorously develop special resins, enhance competitiveness.
