Competitive analysis of thiourea industry in China

What is the competition situation of the thiourea industry in China? At present, there are not many thiourea production enterprises in our country, the distribution of production enterprises is not balanced, and the regional competition is more obvious. Domestic and foreign brands increased competition, but also accelerated the development of the whole thiourea industry. Below is the competition analysis of China’s thiourea industry.
The main raw materials for the production of thiourea are hydrogen sulfide and lime nitrogen. Hydrogen sulfide can be provided by waste gypsum, which is used to produce thiourea, which not only solves the problem of the waste gypsum residue stacking and pollution, but also expands the scope of production and application of waste gypsum. 1t gypsum is equivalent to 0.25t of hydrogen sulfide, the production of 10 thousand T thiourea requires hydrogen sulfide 4480t, which can be seen in the production of thiourea product supply of sulfur resources have adequate protection.
China gypsum rich in resources, reserves in the forefront of the world, open-pit mining ore accounted for more than 30% of the total output of gypsum, mainly distributed in the northwest Gansu Hua Zhi Si gypsum mine, Ningxia Gan Tang gypsum mine and Qinghai Xining gypsum ore, for the production of thiourea to provide sufficient raw materials, making China become the largest producer of products of thiourea, and occupied a dominant position in the international market.
In recent years, the production of Thiourea in China has a certain development, production capacity of 80 thousand T, more than 20 manufacturers, of which 50% are barium salt production enterprises. If the production of barium carbonate instability, will lead to low hydrogen sulfide gas concentration is too low, so as to reduce the yield of thiourea, the suppression of technical force is relatively weak manufacturers launched thiourea products.
There are part of the refinery for the recovery of hydrogen sulfide tail gas to buy lime nitrogen production of thiourea, this part of the production of thiourea share of about 40% of the market share of thiourea. In recent years, domestic manufacturers have to expand production capacity to adapt to the rapid growth of market demand.
At present, there are not many thiourea production enterprises in our country, the distribution of production enterprises is not balanced, and the regional competition is more obvious. From the production area distribution, mainly distributed in Shandong, Guizhou, Henan, Hebei, Hunan and other places, so these areas of the thiourea industry competition is more intense.
With the rapid expansion of China’s chemical industry, pesticide and other industries, thiourea products to become a major growth highlights of the industry. Domestic and foreign brands increased competition, but also accelerated the development of the whole thiourea industry.
With the rapid development of medicine, chemical industry, pesticide and other industries, the application of thiourea is more and more widely, and the demand is increasing. Uncertainty of the market competition pattern and the expanding demand of the market, is conducive to the development of new enterprises. Thiourea

Nanjing amino sulfonic acid exported to Italy

A few days ago, by the Tangshan Hebei inspection and Quarantine Bureau of qualified, the area of a number of hazardous chemicals industrial grade amino sulfonic acid exports to Italy. This batch of goods by the Lubon North-China Co.,Ltd, a total of 48 tons, the value of more than 40000 dollars, has the completion of the inspection and the smooth export.
In order to ensure the safety of the shipment of goods, the Tangshan Bureau of early intervention, to increase the risk of chemical and packaging management measures to promote the enterprise to carry out classification and identification of hazardous characteristics. Prior to the custom packaging, the board to help businesses review the packaging, marking and dangerous publicity labels, on-site guidance of the lining of the mouth. At the same time, in strict accordance with the standards of the batch of products to carry out on-site inspection and laboratory testing, to ensure the quality and safety of export products.http://www.sulfamic-acid.com/

2016 first quarter Magnesium Sulfate exports in the top ten rankings

According to the database of Zhongshang Industrial Research Institute, 2016 a quarter of exports of magnesium sulfate points ranked in the top 10 in the country followed by Zimbabwe, Hong Kong, Mozambique, Brunei, South Africa, Sri Lanka, Pakistan, the Philippines, Iraq, and Chile.
Which, the ten countries of magnesium sulfate exports than last year over the same period were growth 800%, fell 10.3%, 76% growth, growth 5290%, 82.6% growth, growth of 28.7%, increase of 6.9%, 7.5% growth, growth 7042.9%, and increase of 17.1%. Export amount, the ten countries magnesium sulfate and the amount of exports than last year over the same period were growth 639.3%, down 12.9% and 115.5% growth, growth 3198.6%, 100% growth, growth of 16.3%, fell by 5.8%, down 27.3%, growth 8679.8% and increase of 8.6%.Magnesium sulphate (sulfate)

[new process] magnesium method desulfurization by-product – seven water Magnesium Sulfate refining new process

Magnesium oxide method flue gas desulfurization is a mature technology, economic reasonable, reliable operation of wet desulfurization technology, using cheap, low grade industrial magnesium oxide MgO85% as a desulfurization agent, especially suitable for magnesium mineral rich areas.
Magnesium desulfurization by-product mainly for Magnesium Sulfate, the common way to deal with a direct way to abandon the law, Magnesium Oxide regeneration method, Magnesium Sulfate recovery method. Direct abandonment process is simple, but the waste of resources, emissions by GB 8978 “sewage comprehensive emission standards” appropriate treatment, discharge standards, more common in small desulfurization system. Magnesium Oxide regeneration method is the MgSO4 and MgSO3 calcination decomposition, recycling MgO for desulfurization, recycling SO2 used for the production of sulfuric acid, complex process, high cost of renewable, suitable for sulfuric acid industry desulfurization system. Magnesium Sulfate recovery process is also more complex, but the value is high, the prospect is broad, applicable to large and medium-sized desulfurization system. The conventional recovery process of magnesium desulphurization by-product (Magnesium Sulfate) generally increases the additional evaporation crystallization heat source, the energy consumption is higher, not the economy.
    Lubon North-China for large-scale magnesium method desulfurization system design in the seven water magnesium sulfate purification process available minimal investment, to the lowest operating cost and the minimum equipment failure rate, high-quality products, magnesium sulfate heptahydrate income in line with industrial grade heptahydrate magnesium sulfate quality refers to the standard (see table).
For the refining technology of desulfurization by-product magnesium sulfate heptahydrate, to ensure the quality of products, is the key for the removal of heavy metal ions, by Newth Taryn integration tower, also dust removal, desulfurization, and do not interfere with each other. To be flue gas in most of the dust and heavy metal ions removal has been immediately desulfurization produce magnesium sulfite, oxidation obtained magnesium sulfate solution, magnesium sulfate after pre processing, crystallization refining, centrifugal separation and drying process, industrial grade magnesium sulfate heptahydrate.
Among them, the heat required for Magnesium Sulfate crystallization system comes from boiler flue gas waste heat, greatly reduce energy consumption.
In the condition: the flue gas is 200 thousand Nm3/h, the flue gas temperature is 140 degrees, the SO2 content of 1000mg/Nm3 takes off to 35mg/Nm3, and the annual running time is 7000 hours.Magnesium sulphate (sulfate)
