Methanol overcapacity is now of great significance to launch MTG

in recent years, China's methanol industry as a whole has a serious overcapacity. How to extend the industrial chain, develop competitive derivative products, break through the surplus pattern, improve the profitability of methanol plants, and then promote industrial adjustment and upgrading has become an important topic in the methanol industry. Methanol synthetic gasoline technology (MTG) is favored by more and more methanol enterprises and investors because of its advantages such as short process, relatively flexible plant scale, less investment and obvious benefits. In particular, methanol to gasoline projects of many enterprises have been put into operation this year, which has attracted great attention in the industry. What is the significance of developing MTG? What economic and social benefits can MTG project bring? Can MTG rely on its own advantages to become a sharp weapon to resolve domestic methanol overcapacity

According to gezhiying, chief engineer of Inner Mongolia Menghua Energy Co., Ltd., MTG technology refers to the process of dehydration, oligomerization and isomerization of methanol into hydrocarbon oil below C11 through catalysts at a certain temperature, pressure and space velocity

"MTG technology has been relatively mature, ExxonMobil (USA) MTG technology has more than 10 years of large-scale operation experience in New Zealand. On this basis, the second generation MTG technology has been developed at home and abroad. Using the second-generation technology, many projects such as Tianxi company of Shanxi Coal Group 100000 tons/year and Yunnan Xianfeng Chemical Co., Ltd. 200000 tons/year have been put into operation successively, producing 93 × high clean gasoline with gasoline quality higher than that of petroleum refining process, and realizing full load operation and stable operation. " Ge Zhiying said

it was also learned in the interview that at present, there are mainly two mature MTG technologies that have completed the industrial operation practice at home and abroad, which are developed by ExxonMobil company of the United States and Shanxi Institute of coal chemistry, Chinese Academy of Sciences in conjunction with Sedin engineering company. According to incomplete statistics, by the end of 2014, relying on these two technologies, more than 10 projects have been successfully put into operation in China, with an annual production capacity of nearly 1.3 million tons, including 100000 tons/year of Tianxi company of Shanxi coal group, two sets of 100000 tons/year of lie guqinghua Group Co., Ltd., two sets of isosceles 3-angle impact point in Inner Mongolia, 200000 tons/year of Yunnan Xianfeng Chemical Co., Ltd., 140000 tons/year of Inner Mongolia Sanwei Coal Chemical Technology Co., Ltd Hebei Xiyao New Energy Technology Co., Ltd. 100000 tons/year, Xinjiang Xinye energy and Chemical Co., Ltd. 100000 tons/year, Inner Mongolia Fenghui Chemical Co., Ltd. 300000 tons/year, Tangshan Jingjie Industrial Co., Ltd. 200000 tons/year, most of which were completed and put into operation this year. In addition, there are nearly 30 proposed projects under construction, with a planned annual production capacity of 9million tons, and the total production capacity of the projects put into operation and proposed projects under construction exceeds 10million tons/year, which marks that MTG has jumped to a new force for the transfer and demonstration of the domestic methanol industry

Ge Zhiying pointed out that the gradual rise in domestic MTG project investment is mainly due to the continuous maturity and improvement of the technology and the successful demonstration effect of industrialization and commercialization. In terms of the project economy and investment market prospect, it is optimistic. On the one hand, using coal to methanol as raw material and MTG process to produce gasoline at the current coal price has certain profitability and anti price risk ability. The profitability and anti price risk ability of MTG project of purchased methanol are reduced, but the sales revenue of by-products can resist project risks within a certain range of achieving common revitalization and development. There is no technical problem in extracting and purifying Mesitylene from the mixed aromatics of MTG by-product, and the distillation unit with relatively high investment in petrochemical C10 aromatics purification method can be omitted. The purification and separation cost is low, and the purity can meet the requirements of downstream users. If the MTG project is combined with the deep processing of mixed aromatics, the economic benefits are significant; On the other hand, MTG process can directly produce clean gasoline with high octane number, and can also be used as a blending component of petroleum refining gasoline to improve gasoline quality, which is in line with China's recent development strategy of taking making up for the shortage of oil as the main goal, focusing on the development of alternative fuels for vehicles, and solving the shortage of fuel for vehicles

Li zhanliang, deputy general manager of the coal chemical industry division of Jin coal group, shares the same view with Ge Zhiying. He told that taking the 1million ton/year MTG project under construction by Jin coal group as an example, the total investment of the project is nearly 3 billion yuan. After completion and operation, it can digest 2.5 million tons of methanol annually, produce 870000 tons of high-quality clean gasoline, 130000 tons of LPG and 130000 tons of mesitylene mixture. According to the feasibility study report of the project, based on the tax price of 8850 yuan/ton of gasoline (including 1380 yuan/ton of fuel tax), 6500 yuan/ton of LPG and 6000 yuan/ton of mesitylene mixture, it is expected that after the project is completed and put into operation, the sales revenue will be 9.3 billion yuan/year, the total profit and tax will be 2 billion yuan/year, the internal rate of return before and after income tax of the project will be 16.78% and 13.39% respectively, and attention will be paid to cultivating local professionals%, Both are 12% higher than the industry benchmark rate of return. The static investment payback period before income tax is 7.15 years, and the static investment payback period after income tax is 8.17 years, which has strong profitability

under the new normal, the development of MTG is of great significance

Guo Xinyu, chairman of Jiangsu coal and chemical engineering research and Design Institute, said in an interview that MTG has improved the downstream development technology level of methanol, formed another mature technology to promote the upgrading of methanol industry, and can also become the successor industry chain of methanol and reduce excess capacity

Guo Xinyu said that MTG gasoline is of high quality and more environmentally friendly, which brings new opportunities for the development of methanol to prepare clean fuels. Compared with petroleum refined gasoline, MTG gasoline has a higher octane number; There is no sulfur in the raw material or a small amount of sulfur is brought in, and the sulfur content of the product can meet the national five standards; The aromatic hydrocarbon content, olefin content and benzene content of the product are far better than the requirements of the national third and fourth gasoline standards. It can be sold separately as a market, and it can also be used as one of the effective measures to solve gasoline quality problems at a low cost. It can also be used to blend reforming gasoline with high aromatic content and catalytic gasoline with high olefin content in refineries

at the same time, MTG can alleviate the contradiction of methanol overcapacity. At present, China's methanol production capacity is about 70million tons/year, while the actual consumption is about 50% or 60% of the production capacity value. In 2020, the methanol production capacity is expected to reach about 85million tons/year. Since this year, as China's economy has continued to operate at a low level and market demand has shrunk, many methanol enterprises have reduced production and stopped production, and the problem of methanol overcapacity is particularly prominent. Actively exploring the way out for methanol products and maintaining the continuous and stable production of existing units will be of great importance to the survival of enterprises. In terms of methanol consumption, for every 1 ton of gasoline produced, 2.5 tons of methanol are consumed, so a 300000 t/a MTG production line can consume about 750000 tons of methanol annually, and the effect of methanol reduction is considerable

"Whether MTG can gain a foothold in China depends on whether there is excess methanol. In other words, MTG can take on the important task of resolving excess methanol and promoting industrial upgrading. If there is excess methanol, MTG may become a good way to extend the industrial chain downstream of methanol. The recovery of MTG in recent years also fully reveals this possibility. Now, some domestic methanol enterprises are generally watching closely, and more and more enterprises consulting and investigating MTG technology and projects More. " Said tanghongqing, technical consultant of Zhongke Synthetic Oil Engineering Co., Ltd

According to Tang Hongqing's analysis, from an economic point of view, methanol synthetic gasoline is related to the market price of crude oil. When the price of crude oil is higher than $70 per barrel, enterprises in methanol producing areas can remove the "Curse" of excess capacity and stabilize their feet. When crude oil prices return to normal levels or soar, MTG's profitability will rise. After the crude oil price broke through $100 per barrel, the call for finding alternative petroleum energy and opening up new sources of chemical raw materials is also growing, and MTG will receive more attention. In addition, although methanol is directly mixed with gasoline to form methanol gasoline fuel has been widely used, it is more attractive to convert methanol into gasoline. Adding methanol to gasoline is not as good as MTG, which has no impact on environmental protection and engine, and is much more convenient. Moreover, the problems of methanol and gasoline blended combustion involving national fuel standards have not been solved

Su Zhigang, general manager of the transportation and marketing department of Boyuan chemical group, pointed out that China is expected to have a surplus of methanol in 2015, and the life of methanol enterprises is not easy. MTG is indeed a good outlet for the development of methanol to the downstream industrial chain, and compared with other downstream methanol technologies, the methanol conversion to gasoline technology is relatively simple, and has certain advantages in reactor technology, oil post-treatment technology and oil quality. From the perspective of production and operation, one of the advantages of its production process is that methanol synthesis process and MTG process are connected by liquid methanol, which can be easily stored in a methanol storage tank. The two sets of devices can be operated independently without complete shutdown of the whole device

mtg needs to break through the bottleneck if it wants to shoulder the heavy responsibility

although MTG has many advantages in many aspects such as technology, environmental protection and economy, it still needs to overcome many difficulties to truly shoulder the heavy responsibility of adjusting and upgrading the methanol industry and resolving excess capacity

Wang Lei, general manager of Yunnan Jiehua clean energy development Co., Ltd., said: "Our 200000 t/a MTG project has been put into operation, which provides a demonstration for the upgrading of the domestic methanol industry. It has broken through seven technical systems and obtained 24 technical patents. Its technological innovation can solve the environmental protection problems of traditional coal chemical technology in the industrialization, and its technical level can be described as domestic leading and world-class. However, at present, Yunnan MTG project still faces many problems such as financing, construction of coal transportation special lines, and market access is currently facing The biggest challenge is that at present, MTG is facing policy problems such as no way to sell oil products. "

Li zhanliang revealed to that Jinmei group is the first MTG enterprise in China to successfully realize industrialized production. Whether MTG can undertake the important task of methanol transfer depends on two factors: first, consumption tax. According to the national tax rules, the consumption tax on gasoline is 1388 yuan/ton, equivalent to 1 yuan per liter. After accounting, the consumption tax accounts for nearly 20% of the unit manufacturing cost of the project, which increases the cost pressure on the production and operation of the project, while other coal chemical products do not need to bear the consumption tax; Second, the follow-up market development space of methanol gasoline may be impacted by methanol blended fuel. At present, although methanol fuel lacks relevant supporting policies, such as pricing mechanism, fiscal and tax policies, development mode, technical platform and other support, the production, sales and application of alcohol ether fuel lack scientific guidance and norms. However, at present, some provinces in China are carrying out large-scale methanol fueled vehicle pilot projects. If the pilot is successful, a high proportion of methanol vehicle alternative fuels such as M85 or M100 may be widely promoted, which will open up another new downstream consumption channel for China's methanol industry and have a certain impact on the market sales of MTG projects; Third, the next few years will be the centralized release period of China's coal to olefin capacity. The release of methanol to olefin unit capacity may push up the price of methanol, which will greatly weaken the competitiveness of MTG at that time

lizhihai, deputy general manager of Inner Mongolia Zhongneng Coal Chemical Technology Co., Ltd., said that the unit capacity investment and unit energy investment of methanol to gasoline are roughly equivalent to that of direct or indirect coal liquefaction to oil; Due to different processes, the unit product cost and unit energy cost of methanol to gasoline are higher than those of direct coal liquefaction or indirect coal liquefaction. At present, there is a lack of effective management for adding a certain proportion of methanol to gasoline in the market, and it defaults to one volume
