Fundamentally improve the intrinsic safety level of the petroleum and chemical industries
2019-05-28
As we all know, the chemical industry is the basic industry and pillar industry of the national economy. Chemical products are closely related to people's production and life. From food and clothing to cutting-edge high-tech fields, chemical products are everywhere and everywhere. In particular, new chemical materials occupy an important position in the national economy. Its development status is an important manifestation of the development level of a country's manufacturing industry, and it is a competitive commanding point for developed countries to compete for. Without the superiority and strength of the chemical industry, the goal of a manufacturing powerhouse will be difficult to achieve, and people's living standards and quality will also be greatly affected. At the same time, many dangerous chemicals and their production processes are characterized by high temperature and high pressure, flammable, explosive, toxic and harmful. The production process is not standardized, management supervision is not in place, disposal measures are not appropriate, and it is easy to cause safety and environmental accidents. The important position and special nature of the chemical industry determine the extreme importance of safe development, green development and responsible care for the healthy and sustainable development of the industry.
Responsible Care is a self-regulatory action in the global chemical industry. Since the launch of the Global Responsible Care Charter from the International Federation of Chemical Industry Associations in 2005 to the world chemical industry, it means that the global chemical industry must consciously assume the safety production, occupational health, energy conservation and environmental protection of the petroleum and chemical industries while developing the chemical industry. The initiative of green development and greater responsibility. The implementation of Responsible Care in the chemical industry means that the company should implement the main responsibility, improve the intrinsic safety level, achieve green development, and effectively control the safety and environmental risks while meeting the needs of people's material needs, improving people's quality of life and creating a better life. Especially in the current critical period of China's chemical industry climbing the slopes, rolling stones up the mountain, and transforming to high-quality development, low-end overcapacity and high-end capacity supply are insufficient, innovation ability is not strong, resource and environmental capacity is limited, and enterprise management is uneven. With the rapid growth of market demand, the lag of the standardization of chemical parks and the acceleration of the relocation of hazardous chemicals enterprises, and many other factors, the potential hidden dangers of serious safety and environmental accidents are many. China's chemical industry is facing a severe situation with frequent and extraordinary accidents. Green development faces a arduous and arduous task. Responsible care is faced with the urgent mission of raising awareness, improving the level, and taking responsibility. It must be done without delay. We must not cover the ugly and short-sighted, ill-health, and develop the chemical industry at the expense of safety and environmental protection. We must not do nothing, squander waste, squander martial arts, artificially limit or even abandon the development of the chemical industry. We must comprehensively understand and thoroughly implement Xi Jinping's socialist ideology with Chinese characteristics in the new era, adhere to the problem-oriented, follow the roots of problems, find the bull's-eye, and draw a conclusion, cross-cutting, comprehensive physical examination, comprehensive rectification, and overall improvement, and embark on a safe and environmentally friendly, A new path of high-quality development of green and low-carbon, with the determination and courage of the strong man to break the wrist to win the hard work and amnesty of the whole society and the whole industry.
Below, combined with the theme of this conference, "Safety Improvement, Green Development, and Responsibility", I will focus on three opinions:
First, the next effort to enhance the safety production level of the whole industry
Since 2018, our industry has successively suffered major accidents such as the “7·12” accident in Yibin, the “11•28” accident in Zhangjiakou, and the “3•21” accident in Yancheng, causing huge losses to the lives and property of the people. Operation has a huge negative impact. The first

Environmental regulations are tightening, consumer demand is growing, and water treatment chemicals are promising
Freshwater market opportunities
For water treatment chemicals producers, the tighter the supply of freshwater resources, the greater the market opportunity for water treatment chemicals. Bettina Blottko, head of the LANXESS liquid purification technology business unit, said that due to insufficient freshwater resources, the demand for wastewater purification and desalination is increasing, and water purification technology is particularly important in meeting the needs of wastewater treatment and desalination.
In addition to the growing urban population that has increased demand for drinking water, there are also markets for water treatment chemicals in growth industries such as chemicals, food, electronics and batteries. According to Blottko's data, overall sales of the ion exchange resin market for water treatment chemicals are expected to increase at a rate of 5% per year by 2022. The demand for membranes for water treatment will increase at a higher rate, and the market for permeable membranes will grow at a rate of 11% per year.
Jennifer Bailey, global marketing director for Solenis' pulp and paper water business, also said the company is very optimistic about the future of the water treatment industry. In the global heavy industry sector, especially in areas with scarce water resources or poor water quality, demand for water reuse and water use is increasing.
Kemira spokesman Tero Huovinen said that water treatment chemicals will continue to grow steadily, which is not affected by economic fluctuations. Water shortages are a threat and an opportunity.
Environmental protection becomes a contributing factor
Environmental regulations have always had a major impact on the water treatment chemicals industry, especially in terms of technology. Recently, the implementation of stricter environmental regulations in developing countries in Asia is both a challenge and an opportunity for water treatment chemicals producers.
LANXESS said that due to the introduction of stricter environmental regulations, it is expected that the water treatment technology market will grow faster in the next five years. Population growth and industrial production growth in Asian developing countries will drive growth in the water treatment market and will also integrate market suppliers. In the long run, environmental regulations will promote the survival of the fittest in the ion exchange resin industry.
Kemira said that more stringent environmental regulations in the future will benefit the water treatment industry. The limits for different pollutants in the current EU urban wastewater treatment regulations are not critical and the maximum limits for biological oxygen demand, chemical oxygen demand, total suspended solids and phosphorus should be tightened. Kemira called on the EU and institutions around the world to further enforce strict environmental regulations.
Digital new technology brings benefits
For the water treatment industry, digital new technologies such as artificial intelligence and IoT technology are also having a major impact on the industry, and there are many benefits. Digital technology can improve the quality of water quality monitoring and the cost-effectiveness of water treatment. Huovinen said: "Digital and advanced monitoring technologies can achieve 20% to 30% increase in process efficiency in water treatment plants. Using these new technologies without increasing processing costs, visibility of key process parameters can be improved."
Blottko said that efficient processing and recycling methods are critical to meeting future water needs. Smart technology and tailor-made products can help develop sustainable solutions that provide more efficient water management for industry and agriculture. Through digital technology, LANXESS has established a highly efficient wastewater treatment method that combines ion exchange resin with reverse osmosis membranes. Nearly zero wastewater discharge is achieved after application in a textile printing and dyeing plant in India.

The aniline industry is in a downturn
2019-04-28
At present, China's aniline industry is transparent in price and shrinks in profits. Under the circumstance of sluggish market, factories are unlikely to reach a consensus on capacity reduction. However, in the future, supply-side reform will lead to a new round of mergers and reorganizations. The backward production capacity will be eliminated, and the essence of the industry will be further concentrated.

Preparation of potassium sulfate from sea salt brine
The high-temperature salt and potassium chloride preparation potassium sulfate process is a high-temperature salt produced in the production of bitter hail potassium chloride as a raw material, and a high-temperature salt and potassium chloride are subjected to a conversion to obtain a mixture of potassium magnesium salt and sodium chloride. Then, a fatty acid amine collector and a mushroom enol foaming agent and a mother liquor produced by the system are added into the material to prepare a slurry, which is sent to a flotation machine for flotation separation to obtain soft potassium magnesium strontium and an industrial salt. Soft potassium magnesium is divided into two parts in aqueous solution to obtain potassium sulfate;
The flotation method of bitter brine and potassium chloride to prepare potassium sulfate is a system of self-produced carnallite and bitter brine to separate bitter salt and then evaporate and concentrate to obtain mixed salt, mixed salt and potassium chloride and system white. The potassium-producing mother liquor is added to the collector and the foaming agent after a conversion, and the soft potassium magnesium and sodium chloride are separated by a flotation machine, and the potassium potassium sulfate is separated from the potassium chloride and water to obtain potassium sulfate:
The spin-flow method of bitter brine and potassium chloride to prepare potassium sulfate is composed of bitter brine to prepare potassium chloride, cyclone separation of high-temperature salt, magnesium sulfate and potassium chloride in one step to obtain potassium sulfate. The production method is The high temperature salt in the production of potassium chloride is separated from the magnesium chloride solution by using a magnesium chloride solution as a medium to separate magnesium sulfate monohydrate and sodium chloride, and magnesium sulfate monohydrate is used to prepare potassium sulfate by a two-step conversion method;
The high-temperature salting-out method of bitter brine and potassium chloride to prepare potassium sulfate comprises the steps of halogenation, one-stage evaporation, high-temperature salting out, two-stage evaporation, cooling, one-stage conversion, two-stage conversion, drying, and the like;
The ion exchange method is to solve the problem of adding potassium chloride in the process of producing potassium sulfate due to the imbalance of potassium ions and sulfate ions in the brine during the preparation of potassium sulfate in the brine, and directly extracting potassium sulfate from seawater. It can open a new path for China's self-sufficiency of potassium fertilizer. The method is to pass seawater through an exchange column containing natural adsorbents, so that potassium ions are adsorbed on the exchanger, and then the circulating liquid of the system is superimposed and adsorbed through the exchange column. The saturated brine is eluted from the potassium ions in the exchange column at a high temperature to obtain a potassium-rich eluent and a circulating liquid, and the potassium-rich eluent is returned to the old halogen, and the composition is adjusted to evaporate to a large precipitation of sodium chloride. When the anhydrous potassium magnesium ruthenium is close to saturation, the solid phase is separated and washed with a potassium-rich eluent to separate and dry to be a fine salt. The clear liquid continues to evaporate until the anhydrous potassium magnesium is precipitated relatively completely, and the potassium chloride does not precipitate and ends the evaporation. The evaporation completion liquid is thermally insulated and settled, and the clear liquid is cooled to obtain the carnallite and the old halogen. The carnallite is decomposed by the potassium sulfate mother liquor to produce potassium chloride and a decomposition liquid, and the slurry is obtained by a flotation method. Potassium chloride and magnesium Rocky separated, after kieserite with water and potassium chloride and potassium sulfate was isolated as the reaction mother liquor, the process is in the development stage;
The liquid membrane method for extracting potassium sulfate from brine is to establish a liquid membrane extraction system with stable chemical and physical properties by selecting a high-efficiency carrier for liquid potassium extraction, and to increase the adsorption amount of potassium to meet the requirements of potassium extraction from brine.
Although the preparation of potassium sulfate from Haihu salt brine still has certain defects, if some processes need to evaporate a large amount of water, the energy consumption is large, some processes are long, the rate of potassium sulfate
