CNOOC is not afraid of overcapacity and launched coal chemical project
CNOOC was informed that the signing ceremony for the construction contract of China National Offshore Oil Huahe 3052 Fertilizer Project (hereinafter referred to as “3052 Projectâ€) was held in Beijing on July 8. The project is located in Hegang, Heilongjiang, and is scheduled to be completed and put into operation in October 2013. For CNOOC, the 3052 project is the first coal chemical project invested and constructed in Northeast China. The project uses coal as raw material, uses GE's coal-water slurry gasification process and low-pressure synthesis process carbonic anhydride gas extraction ammonium nitrate process, The annual production capacity is 300,000 tons of synthetic ammonia and 520,000 tons of large-particle urea. In order to transform itself from an oil and gas exploration upstream company to an integrated energy group, CNOOC has invested in many energy projects other than offshore oil and gas exploration in recent years. Coal chemical industry is also one of them. In addition to the 3052 project, CNOOC has also invested in coal and natural gas and other coal chemical projects in Shanxi and Inner Mongolia. However, the overcapacity situation in the domestic coal chemical industry has become more and more serious. The relevant departments have repeatedly stated that they will strictly control coal chemical projects. In March last year, the National Development and Reform Commission issued the "Circular on Regulating the Orderly Development of the Coal Chemical Industry", and urged all localities to further strengthen the examination and approval management of coal chemical projects, without delegating examination and approval authority, slicing to zero, and non-compliance approval. The notice also pointed out that some companies take the advantage of coal resources in the name of developing coal chemical industry. The blind arrangement of the project results in a lot of redundant construction. However, the enthusiasm of all companies to start coal chemical projects has not been "cast away." According to Li Ye, director of the Energy Conservation and Technology Equipment Division of the National Energy Administration, the National Development and Reform Commission has received 104 large-scale coal chemical projects that have been officially reported from all over the country, with an investment of up to 2 trillion yuan. Li Ye said: "It is obviously impossible for these projects to start construction during the 12th Five-Year Plan period." Non-woven special equipment accessories
Non-woven fabric is a new type of modern material. It has a wide range of uses and can play more roles in clothing, agriculture and industry. The production of non-woven fabrics is also mostly mechanized, which makes it possible to produce a large number of non-woven fabrics in batches. Non-woven fabric winders are one of its equipment.
Non-woven fabric, also called non-woven fabric, is composed of oriented or random fibers. The production of non-woven fabrics often uses polypropylene pellets as raw materials, and is produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. In the production of non-woven fabrics, the raw materials need to be spun and formed and then processed. In the web-forming work, a non-woven web forming machine needs to be used. The web forming machine uses wind in the drafting duct to process the silk. After drafting, a machine for non-directional weaving into a net is carried out. However, polypropylene pellets are prone to broken filaments and stiff blocks during drawing, drafting, and web formation. Therefore, in order to improve the quality of the finished non-woven fabric, it is necessary to clean the formed non-woven fabric. When dealing with broken wires and stiff blocks in traditional web forming machines, workers usually use brushes or scouring pads behind the web forming machines to clean up. Because the belt width of the web forming machines is relatively long, and the conveyor belt speed is relatively high at the same time. Fast, the cleaning range that workers can cover is limited, resulting in low cleaning efficiency, which in turn affects the quality of the finished non-woven fabric.
The slitting machine is mainly used to cut large-format non-woven fabrics into multiple small non-woven fabrics of different widths for processing non-woven products. The equipment adopts DC speed regulation, feeding constant tension control, air knife slitting, rewinding pressure and other devices. The rewinding tightness after slitting is adjustable, and the slitting end surface is flat. The equipment is of high quality and beautiful appearance. It is the ideal equipment for the slitting of large non-woven fabrics. In addition, according to the needs of users, the equipment can also add a dummy cutting function, that is, the original fabric is dummy cut and then slit and rewinded.
Non-woven fabric machinery is a general term for the production of non-woven fabric products, and adopts an overall modular design with a compact and reasonable structure. The control part adopts advanced PLC microcomputer control, and the international famous brand frequency converter speed regulation.
