Petrochemical Filtration Devices
In petrochemical industry and fine chemical industry, chemical reactor will be used for catalytic reaction, and a large number of noble metal catalysts will be used in the process of catalytic reaction, which requires filtration and separation. The reactor can be divided into batch reactor and continuous reactor. Both reactors need a large number of noble metal catalysts. In the actual production process, catalyst leakage often occurs, resulting in increased cost and environmental pollution. Therefore, efficient filtration method is needed to separate catalyst filtration.
According to the different parameters such as temperature, flow rate, solid content, Ph value and viscosity, different filter devices are selected.
With the heavy quality of FCC feed-stock, the yield of catalytic oil slurry becomes larger and larger, because the slurry contains a certain amount of solid impurities (mainly composed of catalyst particles and colloid and asphaltene attached to the catalyst). More solid matter not only increases the erosion of pipelines and equipment, but also has the danger of blockage furnace drunken, which seriously affects the quality of feed-stock oil. Therefore, if the solid matter in the slurry can be filtered out, the quality of the slurry will be improved, and the application will become more extensive, thus increasing the added value of the slurry product. Slurry filter is a kind of solid-liquid separation equipment which can filter the solid matter above microns in the slurry.

The price trend began to rise and fall. In 2005, the polypropylene market experienced two ups and downs. In the first quarter, the volume of polypropylene market was enlarged and prices continued to rise. The average monthly price of T300 rose from 10,120 yuan (t price, the same in the following) in January to 11,325 yuan in March; the polypropylene market was under the intervention of speculators at the beginning of the second quarter. , conducted crazy speculation, the average monthly price in April rose sharply to 11,900 yuan, but in May the polypropylene market is driven by Shanghai Secco's polypropylene plant, Daqing Refining & Chemical's annual output of 300,000 tons of polypropylene by the end of May As a result, the market price has fluctuated sharply and the average price of the market has plummeted to 10,920 yuan. In June, a large number of pressure discs poured out from the polypropylene market, prices continued to fall, and finally fell to around 10,700 yuan. In the third quarter, due to Taiwan’s PetroChina ethylene plant, In the event of an explosion, the price of polypropylene rose with the increase in the price of polyethylene. The average price in July rose again to about 11,300 yuan. It was also high in August, until the polypropylene market was heavily profitable in September. Under the pressure of selling, the price began to fall; in October, the domestic polypropylene market price fell rapidly under the international crude oil prices, the price trend was weak, and the average monthly price fell to 10,700 yuan.
The market presents three major characteristics In 2005, the polypropylene market showed three characteristics:
First, the prices of propylene and polypropylene rose significantly lower than that of crude oil. From January to October of 2005, under the influence of the international crude oil price increase and the hurricane, the decrease in the polypropylene utilization rate led to the increase in the prices of international propylene and polypropylene. According to statistics, the average price of polypropylene in Southeast Asia from January to October was 1,076 US dollars, up 14.7% from 938 US dollars in the same period of last year; the average price of polypropylene T300 from January to October in East China was 11,000 yuan, compared with the same period of last year. The average price of 9535 yuan rose 15.36%, but the increase was far less than crude oil, and the profit of the product chain was highly concentrated on the crude oil leader.
The second is the prosperous production and sales of polypropylene. The output of domestic polypropylene from January to August was 3.288 million tons, an increase of 7.2% over the previous year. It is estimated that the polypropylene production this year will be 5 million tons. From January to August, imports amounted to 2.027 million tons, an increase of 4% over the same period of last year. It is estimated that the annual import volume will be 3 million tons and the annual apparent consumption will be around 8 million tons. With the continuous increase of China's agricultural investment, this year, agricultural water pipes have shown a significant growth. Demand for the packaging industry, construction industry and electronics and electronics remained flat. Polypropylene was still growing steadily.
Third, the number of polypropylene grades continues to increase. In East China, there are currently dozens of typical polypropylene grades such as T300, F401, and F280 biaxially stretched film materials, EPS30R, J340, and K8003. However, despite the fact that the output of polypropylene injection molding in China still cannot meet the demand, it still needs to come from Korea and Japan. , Singapore, Europe, the United States and the Middle East to import, to make up for domestic deficiencies.
In the afternoon, the trend of the market continued to decline steadily. The main reasons affecting the market in the second half of 2005 are the following:
The first is the impact of macroeconomics on the plastics market. In the country's control of the scale of fixed assets, especially under the strict control of real estate, the demand for the polypropylene market will be subject to a certain degree of impact, prices may slightly lower.
The second is to increase domestic production capacity and increase market pressure. Since the beginning of this year, the domestic polypropylene production capacity has been faster, with 200,000 tons added to Dalian Petrochemical, 300,000 tons added by Daqing Petrochemical, 300,000 tons from Lanzhou Petrochemical, 250,000 tons from Shanghai SAC, and 240,000 tons from China Shipping Shell. After the competition in the market continued to intensify, the price center of gravity has shown signs of downward movement.
Third, the profits of the polypropylene processing industry have gradually declined. At present, BOPP has experienced oversupply due to excessive production in recent years. In addition, the contradiction in the local supply oversupply of cast film has begun to appear, and the market has experienced a disorderly competition situation. Especially under the influence of some low-end products, the focus of price is continuously moving downward, and the development of the cast film industry chain is relatively unfavorable. According to the analysis of related data, the profitability of PP downstream processing industry has gradually declined under the influence of the high cost of polypropylene products industry.
Fourth, there is still a huge market for polypropylene special materials. In the field of automobiles and home appliances, polypropylene injection molding plastics will have great potential for development. Polypropylene medical specialty materials have high controllable rheological properties, light transmission properties, good mechanical properties and heat resistance in terms of physical properties. , Has a certain market advantage.
Due to the recent decline in international crude oil prices, the decline has gradually become smaller. It is expected that the oil price will stabilize at around US$55/barrel between November and December. Although this oil price will reduce the production cost of domestic polypropylene producers, it will be in RMB. Appreciation, the export of polypropylene products in China, and the pressure on the domestic market will gradually increase. This will have a certain negative impact on the trend of polypropylene prices, and the market price will also show a trend of steady decline.
The fluctuations in the previous period were stable and there was a downturn in the market --- polypropylene market analysis and forecast
From January to October in 2005, the domestic polypropylene market showed a trend of prosperous production and sales under the stimulation of the sharp rise in international crude oil and propylene prices.
