Xinjiang Zhundong to build China's largest coal gas project

The reporter learned from the Xinjiang Uygur Autonomous Region Development and Reform Commission that Xinjiang's Zhundong region will build China's largest coal gas project with a scale of 30 billion cubic meters to promote the development and transformation of Xinjiang's rich coal resources and ensure China's natural gas supply.

According to the Xinjiang Uygur Autonomous Region Development and Reform Commission, the State Development and Reform Commission formally approved the preliminary work of the Xinjiang Jondong Coal Gas Demonstration Project on September 22, 2013.

The scale of the construction of the Zhundong Coal Gas Demonstration Project in Xinjiang reached 30 billion cubic meters per year, matching the scale of Sinopec's “New Yuezhe” pipeline (gas transmission capacity of 30 billion cubic meters per year). The project has built a total of Wucaiwan, Dajing, and West. The five air source projects in Heishan, Karmat and Hefeng are jointly constructed by Sinopec, Huaneng Xinjiang, Xinjiang Longyu Energy, Zhejiang Energy Group and other companies and the Xinjiang Production and Construction Corps. The estimated total investment is 183 billion yuan. It will achieve a sales income of 55 billion yuan, a tax of 10.5 billion yuan, a direct solution to the employment of 18,000 people, and an annual coal consumption of 90 million tons.

The Zhundong region is located in Changji Hui Autonomous Prefecture, Xinjiang. The estimated reserves of coal are 390 billion tons, and proven reserves are 213.6 billion tons. It is China's largest and most resource-rich coal field.

There are many kinds of products which need filtration in industrial production. The material properties of these products are very different, and the purpose of separation is different. Therefore, it is necessary to select the filter equipment scientifically and reasonably according to the production needs such as material characteristics and separation purposes, in order to play its role effectively. 

At present, the requirement of filtration equipment in industry is that the filtration accuracy is high, so that the solid content in the filtrate is low, and even the filtration precision is based on the number of solid particles in the filtrate. 

In order to ensure the stability and reliability of the system, the cleanliness of the oil with precision components such as servo parts is strictly controlled in the international hydraulic system, and the new oil cleanliness is required to reach the fifth grade of the American Aerospace Standard nas1638 (American Aerospace Standard), so as to ensure the stability and reliability of the system. But in reality, the cleanliness of new oil is only 10-11 of nas1638. If the new oil is used without strict filter and purification, it will bring serious harm to the life of the precision components and the reliability of the work of the whole system. The cleanliness of hydraulic oil can be improved fundamentally only when circulating filtration is carried out simultaneously with the operation of hydraulic system. 

Reverse osmosis filtration equipment is widely used in industrial production, industrial pure water system is designed from reverse osmosis process, referred to as reverse osmosis equipment. The water quality of reverse osmosis equipment is required before influent. If the water flow through reverse osmosis membrane directly through high pressure for a long time, it will cause membrane blockage.

 In general, there are multi-medium filters, ion exchange, various kinds of Precision Filters in the pre-treatment equipment of the whole pure water system. These pre-treatment filters can effectively remove the suspended matter in the water. 

According to the needs of the users, different levels of processes are used to make the quality of the produced water up to the standard. Of course, its price is also determined by the configuration of reverse

osmosis equipment.
