wallpapers News 2020-11-18

Current situation: production capacity output continue to grow at a high speed ﹤ consumption driven by real estate automobile ﹣ serious polarization of enterprise scale ﹣ significant improvement of process equipment level ﹣ development status (1) production situation: soda ash is an important basic chemical raw material.

Soda ash industry plays an important role in promoting the development of national economy improving people's living stards.

It is widely used in glass industry, chemical products, detergent, alumina other industries.

In 2002, the production capacity of soda ash was only 11 million tons, which reached 28.

7 million tons in 2012, with an average annual growth rate of 10%.

Among them, the capacity of combined alkali process is 14.

4 million tons, accounting for 50% of the total capacity.

the capacity of ammonia alkali process is 12.

5 million tons, accounting for 44%.

the capacity of natural alkali process is 1.

8 million tons, accounting for 6%.

According to the statistics of China Soda Ash Industry Association, the output of soda ash in 2012 was 24.

01 million tons, 13.

9 million tons higher than that in 2002, with an average annual growth rate of 9%.

Among them, the output of combined alkali process is 12.

02 million tons, accounting for 50% of the total output.

the output of ammonia alkali process is 10.

32 million tons, accounting for 43%.

the output of natural alkali process is 1.

67 million tons, accounting for 7%.

Since 2003, the output of soda ash in China ranks the second in the world, second only to the United States.

In 2012, the domestic soda ash production capacity accounted for 45% of the world's total capacity, the output accounted for 42% of the world's total output.

(2) consumption situation in recent years, driven by the real estate, automobile other industries, the domestic glass industry has developed vigorously, driving the growth of soda ash consumption.

From 2002 to 2012, the average annual growth rate of domestic soda ash consumption was 1.

3 million tons, with an average annual growth rate of 9.2%. At present, 48% of the domestic soda ash production is used for the production of flat glass daily glass, 20% for the production of inorganic salt products, 5% for the production of synthetic washing powder, 2% for the production of alumina, 7% for export, the remaining 18% for the production of other industrial products inventory.

(3) organizational structure capacity distribution of enterprises.

At present, there are 44 soda ash production enterprises in China (53 sets of production plants), accounting for more than half of the total number of soda ash enterprises in the world.

Among them, there are 12 ammonia alkali enterprises, 31 joint alkali enterprises 1 natural alkali enterprise.

The average scale of domestic soda ash enterprises is small polarization is serious.

The scale of the largest enterprises is 3 million tons / year, the minimum is only 30000 tons / year, the average scale is about 650000 tons / year.

there are 19 Enterprises with a production capacity of more than 600000 tons / year, accounting for 79% of the total capacity.

there are 9 enterprises between 300000 600000 tons / year, accounting for 13% of the total capacity.

there are 16 enterprises less than 300000 tons / year, accounting for only 8% of the total capacity.

Domestic soda enterprises are distributed in 22 provincial administrative regions, covering the national consumer market.

Among them, the top five provinces of soda ash production capacity are Shong, Jiangsu, Henan, Hebei Qinghai, accounting for 64.

6% of the total domestic capacity.

(4) process equipment: there are three kinds of soda production processes in China, namely, ammonia alkali process, combined soda process natural alkali process.

Among them, ammonia alkali process is a traditional production process, with good product quality less investment per unit capacity, but the waste residue is large difficult to be treated can only be stored for a long time.

the combined alkali process is a unique production process in China, which has the advantages of less waste residue production high resource utilization efficiency, but it needs supporting construction The ammonia plant has a large investment, most of the combined alkali enterprises are transformed from small chemical fertilizer plants, which has problems of weak technology management high consumption.

the natural alkali process has the advantages of low cost pollution-free, but the production is restricted by the distribution of resources, only one domestic enterprise adopts the process.

In the face of severe market situation, the soda plant of Shong Haihua Co., Ltd. takes the lead in adopting centrifugal dewatering technology in the same industry.

In the original pressure filtration dehydration process device, a new high-tech centrifuge is added to carry out the secondary centrifugal dehydration transformation.

The moisture content of heavy alkali is reduced from 18% to less than 13%, 150 kg of medium pressure steam can be saved per ton of alkali It can reduce consumption cost achieve remarkable results.

The picture shows that the staff of the secondary centrifugal dehydration post are in the process of inspection maintenance.

(Photo by Zhang Qinye) in recent years, China's soda ash enterprises have adopted a large number of new processes, new technologies, new equipment new materials, which have greatly promoted the overall level of technology equipment in the industry: they have developed a new type of shift gas caustic soda process, an uncooled carbonization process, a new type of technology New processes such as melamine tail gas alkali making process, salt alkali calcium recycling process other new processes have emerged, such as dry ash adding technology, vacuum distillation technology, ammonia alkali white mud desulfurization technology, etc Advanced energy-saving emission reduction technologies with independent intellectual property rights, such as calcium carbide slag refining brine technology, centrifuge secondary filtration technology for heavy alkali, flue gas recovery utilization technology, etc.

developed advanced equipment such as 65 square meter horizontal belt type alkali filter, 650 cubic meter carbon dioxide screw compressor, powder flow soda cooler, etc.

, to promote the development of soda ash industry to large-scale, automation high efficiency.

Problems: (1) serious overcapacity, production has been significantly greater than sales, the operating rate of soda ash industry has been maintained above 90% before 2008.

After 2008, affected by the financial crisis the rapid expansion of production capacity, the operating rate of the industry dropped by more than 10 percentage points, only 83% in 2012.

At present, there are still a large number of soda ash production capacity under construction planning in China: there are 11 projects under construction with an annual capacity of 6.

25 million tons, which are expected to be completed put into operation in the next two years.

there are 10 planned projects with a capacity of 7.

4 million tons.

If no strict regulation control measures are introduced, it is estimated that by 2015, the soda ash production capacity will reach 34.

95 million tons or more, while the dem can only be maintained at about 25 million tons.

By then, the capacity will be 10 million tons, the operating rate will be only 71%, which will have a huge negative impact on the development of the national local economy.

(2) the expansion of the loss area has threatened the safety of the industry.

Affected by overcapacity market depression, the soda ash industry has continued to suffer losses.

In 2012, 83% of the ammonia alkali enterprises suffered losses, with the loss amount reaching 1.

974 billion yuan. 54.8% of the combined alkali enterprises suffered losses, with the loss amount of 1.

18 billion yuan.

After the break even, the whole industry lost 2 billion yuan.

In 2013, the market situation of soda ash has not improved, the loss of enterprises has continued to exp.

As of June 2013, soda ash industry has been in a continuous loss for 18 months, 85% of the enterprises are in the state of loss, an increase of 24% compared with 2012.

After the break even, the loss of the industry reachedTo 1.

58 billion yuan.

It is estimated that in the second half of the year, the difficult situation is still difficult to change.

In the long run, a large number of soda ash enterprises will be forced to reduce production or stop production, seriously threatening the safety of soda ash industry.

(3) the treatment of waste liquid waste residue seriously restricts the development of ammonia alkali enterprises.

For each ton of soda ash produced by ammonia alkali process, about 10 cubic meters of waste liquid 300 kg of waste residue will be produced.

At present, most of the world's soda ash enterprises mainly rely on the disposal of ammonia alkali waste liquid by sea discharge, the treatment of ammonia alkali waste residue mainly depends on storage.

With the improvement of production living environment, the living space for ammonia alkali enterprises in the eastern coastal areas will be smaller smaller.

If the development mode can not be changed the pollution emission storage can not be reduced, the survival of ammonia alkali enterprises will face serious constraints of environmental protection.

The reasons are as follows: excessive pursuit of economic growth, investment for the purpose of occupying resources, overestimation of competitive advantage, imperfect exit mechanism of production capacity, lack of means of inspection, reward punishment (1) excessive pursuit of economic growth In order to stimulate GDP employment, some local government departments use administrative power to intervene in the investment behavior of enterprises, resulting in some projects without basic elements such as resources, energy, market, etc.

, some places have not strictly implemented the "Guiding Catalogue for industrial restructuring" "admittance conditions for soda ash industry", resulting in some projects that do not meet the requirements of industrial policies Through the approval filing EIA.

(2) some enterprises take resource possession as the purpose, many enterprises cater to the local regulations that "if they want to obtain resources, they must build large projects locally", invest in the local areas for the purpose of occupying resources.

After 2007, many soda ash projects are aimed at occupying coal mine, salt mine, salt lake other resources for the purpose of seeking greater long-term interests.

(3) some enterprises overestimate their own competitive advantages.

Eastern enterprises think that they are close to the market ignore the problems of high energy prices high financial costs.

western enterprises overemphasize the advantages of resources costs, neglect the problems of long distance from the market, high transportation sales costs, tight transportation capacity.

New enterprises think that they have resources, large scale, new equipment technology, strong competitive advantages.

Although the capacity is already excessive, the old enterprises have low financial costs, close to the market have their inherent advantages, it remains to be seen who is the winner in the cruel market competition.

They are full of self-confidence in the market competition: "to die, certainly not me.

" (4) the mechanism of capacity exit is not perfect.

First, local governments are reluctant to exit enterprises for the sake of GDP, tax revenue employment.

second, banks try their best not to let enterprises exit in order to avoid bad debts dead debts.

third, there are many difficulties such as staff placement no policy support, so enterprises do not want to can not quit until they have to.

(5) the national competent departments lack the means of inspection, reward punishment.

The industrial policies such as the Guiding Catalogue of industrial restructuring the admittance conditions of soda ash industry issued by the national development Reform Commission the Ministry of industry information technology are highly targeted, with clear specific requirements.

If implemented seriously, they will achieve immediate results in curbing the blind expansion of the industry eliminating backward production capacity.

However, although the policy is good, the supervision has not been implemented in place, resulting in the policy implementation effect greatly reduced.

Suggestions: no approval of new projects within five years, implementation of admittance announcement management for enterprises, establishment of exit mechanism, overall consideration of decentralization regulatory functions, guidance of enterprises to implement restructuring integration industry suggestions (1) it is suggested that new soda ash projects should not be approved or filed within five years We will implement the relevant requirements of the guidance catalogue for industrial restructuring the admittance conditions for soda ash industry, banks will not provide loans for new soda ash projects.

(2) the implementation of access announcement management for soda ash enterprises, due to the unclear status of "soda ash industry access conditions" in industrial policies, the local government's executive power is not strong, even the situation of negative treatment protection of illegal enterprises occurs.

Therefore, it is suggested that the soda ash enterprises should be included in the announcement management, so as to implement the admittance conditions of soda ash industry resolve the contradiction of overcapacity.

(3) implement the laws regulations issued, establish an exit mechanism, accelerate the elimination of backward production capacity The energy consumption, environmental protection, quality other aspects of soda ash enterprises shall be inspected.

According to the provisions of "admittance conditions of soda ash industry", "clean production stard of soda ash industry" "energy consumption quota of unit product of soda ash", it is suggested that enterprises that do not meet the requirements should be withdrawn by means of capacity replacement government redemption, so as to accelerate the elimination of backward production capacity.

(4) considering the decentralization supervision functions as a whole, under the premise of imperfect supervision, it is suggested that the relevant state departments should unify the EIA of new soda ash projects the decentralization of project approval authority with the supervision in place, so as to prevent the surplus situation from deteriorating.

(5) to guide enterprises to carry out reorganization integration, which has multiple advantages.

It is not only conducive to the realization of centralized procurement, increasing the discourse power of purchase price, but also conducive to the optimization of sales transportation links, saving costs.

What's more important is to be able to optimize the capacity after falling through restructuring integration, while reducing unnecessary vicious competition.

In view of the overall surplus of soda ash industry some difficulties for enterprises, it is suggested that the government should introduce relevant policies to encourage guide enterprises to carry out merger reorganization.
