38 session of the Chinese sulfur and sulfuric acid Annual Technical Conference 2018 'China parathion titanium industry chain summit held in Hangzhou

The 38th China Sulfur and Sulfuric Acid Technology Annual Conference and 2018' China Sulphur Phosphorus Titanium Industry Chain Summit was held in Hangzhou, Zhejiang Province from August 21st to 24th, 2018. Five expert engineers of our company attended the meeting.

2018 is a crucial year for achieving the development goals of the 13th Five-Year Plan. It is also an important year for the country to promote the “Belt and Road”, supply-side reform, industrial restructuring, energy conservation and emission reduction, and cleaner production. Entering a new era, China's sulfur and sulfuric acid industry and its related upstream and downstream industries such as non-ferrous smelting, phosphate compound fertilizer and titanium dioxide are also facing new development opportunities and challenges. The coordinated development of the sulphur-phosphorus titanium industry chain, the upgrading of the sulphur and sulphuric acid industry and related industries depend on technological advancement and the promotion and application of new technologies, new processes, new equipment and new materials.

China's sulphur-phosphorus titanium industry has entered a high-quality development channel, but it still faces the severe situation of continuous adjustment of industrial policies, resource and environmental constraints, overcapacity, intensified competition in domestic and foreign markets, and insufficient technological innovation. In order to build a domestic first-class technology exchange platform for sulfur and sulfuric acid and related industries, share experiences and achievements in industrial development, product upgrading, quality improvement, technological innovation, energy conservation and environmental protection, and development of circular economy, and analyze problems in the industry and Coping strategies, strengthen communication and understanding between enterprises, discuss the future development of the industry, and promote the development of depth and breadth of the sulphur-phosphorus titanium industry chain. The Chemical Acid Branch of the China National Chemical Industry Association, the National Sulfur and Sulfuric Acid Industry Information Station, and the Sulfuric Acid The editorial department of Industry jointly held the summit.

The theme of the conference highlighted green, energy-saving and environmental protection, and created a sulfur-phosphorus-titanium circular economy industrial chain.

The first is to study the policy market, invite relevant leading experts to analyze and interpret industry-related industries and environmental protection policies, and analyze the market and statistical data of related products such as sulfur, sulfuric acid, pyrite, phosphate compound fertilizer and titanium dioxide.

The second is the exchange of sulfur-phosphorus-titanium circular economy industrial chain, the development of sulfur and sulfuric acid extension products, the utilization technology of pyrite slag resource utilization, the acid recovery technology of waste acid and sulfur-containing waste liquid, phosphogypsum, titanium gypsum and desulfurization gypsum. , ferrous sulfate, sulfur paste sulfur mud and other resources to use acid technology, hydrogen sulfide and other sulfur-containing waste gas dry / wet acid technology and comprehensive utilization of sulfur resources.

The third is to exchange energy-saving emission reduction and clean production technologies, to discuss high-, medium-, and low-temperature heat recovery technologies for sulfur and sulfuric acid and upstream and downstream industries, screw expansion power machines, slag heat recovery devices, heat pipe boilers and other heat recovery technology equipment, and various heat energy. Cascade recycling technology; clean sulfur and sulfuric acid clean production, tail gas sulphur dioxide and sulfuric acid mist treatment, integrated desulfurization, denitrification, mercury removal, arsenic removal, sulphuric acid wastewater reduction and comprehensive utilization

The fourth is the research and application of the exchange of new equipment materials technology. Recent technical research and application of equipment materials such as incinerators, waste heat boilers, fans, converters, catalysts, mist eliminators, liquid-solid separators, pump valves, etc.

At the meeting, relevant domestic and foreign enterprise experts made: analysis and prospect of sulfur and phosphorus market at home and abroad, research and interpretation of industrial policy of sulfur-phosphorus titanium industry, analysis and prospect of operation of sulfuric acid industry, analysis of phosphate fertilizer market and comprehensive utilization of phosphogypsum, operation of titanium dioxide industry Status and prospects, development and prospects of the sulphur-phosphorus titanium industrial chain, progress and prospects of resource utilization of phosphogypsum and titanium gypsum, current status and prospects of sulphur-phosphorus fine chemical products, practical experience of sulphur-phosphorus titanium recycling economy industrial chain; integrated hydrogen peroxide desulfurization In addition to the introduction of acid mist technology.

Participants exchanged and introduced the domestic phosphate gypsum, ferrous sulfate, waste sulfuric acid, sulfur-containing wastewater resource utilization technology, domestic equipment materials and the latest technological achievements of environmental protection companies. Also learned the new edition of the ""National Hazardous Wastes List"" on the interpretation of the sulfur and phosphorus industry content, the national standard sulfuric acid mist detection method research and sulfuric acid fog research and countermeasures.
