"12th Five-Year Plan" new construction, capacity expansion, new production capacity of 11.81 million tons of methanol and olefins
Bulk cement trucks,Composition of parts is vehicle chassis, bulk cement truck tanks, gas line system, automatic discharge device and other components. Suitable for fly ash, cement, lime powder, mineral powder, granules alkali and other particle diameter of not more than 0.1mm powder dry materials transported in bulk. Mainly for cement, cement warehouses and large construction sites, can save a lot of packaging materials and handling labor.

“In 2015, China’s total ethylene production capacity will reach 27 million tons, forming 3 to 4 ethylene production bases with a production capacity of over 2 million tons; the total production capacity of coal and methanol to olefins will reach 6.06 million tons, accounting for 20% of the national total ethylene production capacity. This is the information disclosed by the Petroleum Refining Conference of Shaanxi Yanchang Petroleum Group recently held. On September 8, the reporter made further interviews with relevant experts.
According to experts, the forthcoming “Twelfth Five-Year Plan†of the ethylene industry is clear: China will accelerate the progress of large-scale ethylene projects under construction, launch the “Eleventh Five-Year Plan†project that has been approved, and expand the existing facilities. , And moderate development of methanol and olefins and other ways to significantly increase the domestic ethylene production capacity and self-sufficiency rate. By 2015, China's total ethylene production capacity will reach 27 million tons. Among them, 5-7 new ethylene projects will be added to increase the production capacity of 6.3 million tons of ethylene; the existing capacity of ethylene units will be expanded to increase the capacity of ethylene by 4.4 million tons; 8 MTO/MTP projects will be built; Ten thousand tons. By then, China's ethylene self-sufficiency rate will increase from the current 48% to 70%.
Experts revealed that in order to optimize the layout of the ethylene industry, enhance industrial concentration and competitiveness, and guide the development of the ethylene industry in the direction of “large-scale, integrated, and base-based,†the “planning†requires that during the “12th Five-Year Plan†period, Strengthen and expand the Yangtze River Delta, Pearl River Delta, and Bohai Petrochemical industry clusters, build vinyl floors in the central and western regions, and transform and upgrade the ethylene industry in Northeast China. The specific idea is that the Yangtze River Delta region will use Shanghai, Nanjing, and Zhenhai as the center to form three to four ethylene production bases with a production capacity of more than 2 million tons. The total ethylene production capacity will account for more than one third of the country's total; the Pearl River Delta region will accelerate Maoming and Huizhou. The construction of joint venture projects in Zhanjiang, Jieyang, and other places will focus on the development of advantages and specialty products; the Bohai Rim will be centered on Beijing-Tianjin-Tangshan and Fushun, and large-scale ethylene plants will be built; the Midwest region will rely on large-scale refinery projects in Lanzhou and Chengdu, respectively. Dushanzi forms 3 to 4 vinyl sites.
The second is that new ethylene projects must have adequate and high quality raw materials. An annual output of 1 million tons ethylene plant should be matched with an annual refining capacity of more than 12 million tons; a large-scale oil refinery-ethylene-aromatic-electricity deep integration project, with an annual capacity of more than 20 million tons of refined oil refining capacity per million tons of ethylene.
The third is to accelerate the pace of technological upgrading and capacity expansion of existing ethylene plants, continuously optimize process parameters and ethylene cracking raw materials, increase the scale of the plant, and increase the total yield of high value-added products such as hydrogen, ethylene, propylene, butadiene, and benzene, and reduce Energy consumption per unit of product.
The fourth is to constantly optimize and adjust the raw material route to reduce the cost of ethylene production. Encourage the use of oilfield associated gas and condensate as raw materials to produce ethylene, support the development of industrialization of heavy oil ethylene technology represented by CPP, and moderately develop coal-to-olefin technology represented by MTO and MTP.
