Beijing Shuibiqing Environmental Protection Technology Co., Ltd. Silicone Defoamer-LanzhouThe dosage of polyacrylamide should be based on the clarification of the solution. Add in an appropriate amount. Too much will not only cause insignificant effect, but also increase consumption and affect the passing capacity of the leaf filter. The concentration of liquid polyacrylamide in one preparation should not be too high. If it is too high, the mixing of polyacrylamide and alkaline water will be uneven, and the hydrolysis reaction of polyacrylamide will be insufficient, which will affect the flocculation effect.
The amount of polyacrylamide added is mainly determined by the amount of red mud dissolved and the sedimentation effect. The amount of polyacrylamide will increase when the amount of red mud is large. However, the preparation method has a greater impact on the sedimentation effect of polyacrylamide. Use reasonable The preparation method can improve the sedimentation effect and greatly reduce the consumption of polyacrylamide, which is beneficial to improve the throughput of the sedimentation system.
Although the global polyacrylamide market showed signs of recession in 2009 due to the impact of the financial crisis, it will gradually pick up in 2011 and the market size will reach 2.51 billion US dollars by 2015. The main driving force for market development comes from the recovery of the industry, the profits brought by product-related technical services required by the industry's environmental protection policies, and the rapid growth of emerging markets.
In 2012, the main application areas of polyacrylamide in my country were oil exploitation, water treatment, papermaking, super absorbent resin, metallurgy and coal washing. Its consumption structure is as follows: oilfield mining accounts for 81%, water treatment accounts for 9%, papermaking accounts for 5%, mines account for 2%, and others account for 3%. Petroleum exploitation is the current consumption area of polyacrylamide in my country, and its consumption accounts for 81% of the total domestic consumption. Water treatment is the second largest consumption area of polyacrylamide in my country. The urban sewage treatment rate in China is less than 30%, the recycling rate of industrial water is 60%, and the industrial wastewater treatment rate is 77%, which is a big gap compared with developed countries. The amount of polyacrylamide used as a flocculant in wastewater treatment in my country’s urban water treatment and chemical, metallurgy, paper, printing and dyeing, sugar, monosodium glutamate, coal, building materials and other industries will continue to increase. Mixture, leather retanning agent and other fields.
It is estimated that from 2018 to 2030, the market of polyacrylamide in the four major application fields of oil extraction, mining, papermaking and water treatment will continue to grow at a compound annual growth rate of 7.2%.
In the oil extraction industry, polyacrylamide is used as a drilling coagulant, and it is also used in tertiary oil recovery. The tertiary oil recovery process must be adopted to balance the price. The recovery of drilling and exploration activities will also promote the growth of polyacrylamide consumption. In the drilling and production process, 3 to 6 million low molecular weight polyacrylamide can be used as a flocculation coating agent.
Polyacrylamide is also widely used in the mining industry. It can not only separate minerals and ore, but also can be used as a flocculant in wastewater treatment and sealing mining pipelines. Due to the complex pricing structure, the market demand for cobalt, coal, copper, gold, diamonds and iron ore in South America is also rising, which will promote the growth of the global polyacrylamide market.
