In the new round of private enterprises to start off the ethane cracking project investment boom, enterprises are also driven by profit and other large-scale implementation of coal chemical and petrochemical olefins project. Asianization is expected to 2021, China’s ethylene production capacity will reach 37 million tons, the equivalent demand will reach 44 million tons, the equivalent gap of about 15 million tons, when the Chinese ethylene market is still a huge gap. With the completion of the proposed project, following coal / methanol to olefins, China’s ethylene market pattern ushered in another giant earthquake.
In recent years, in a large number of coal / methanol to olefins, propane dehydrogenation propylene, methane dehydrogenation project put into production in the context of China’s propylene production capacity significantly more than ethylene, and China’s ethylene demand and supply and demand gap is much larger than propylene. In 2016, China’s ethylene production was 17.81 million tons, the equivalent gap reached 20 million tons, representing an increase of 155% in 2006. Such a huge supply and demand gap has become one of the main factors in the enterprise favor ethylene project.
In the new round of private chemical enterprises to set off the ethane cracking ethylene project investment boom, enterprises also due to profit and other large-scale layout of the implementation of coal chemical and traditional petrochemical olefins project. Asian chemical production is expected to 2021 China’s ethylene production capacity will reach 37 million tons, up 87% over 2016, ethylene equivalent demand reached 44 million tons, the equivalent gap of about 15 million tons, ethylene self-sufficiency rate from the current 47% To about 66%, when the ethylene market is still a huge gap.
In different raw materials and production processes, ethylene production there is a big difference. Ethylene as raw material, the highest yield of ethylene cracking, while by-product of a large number of hydrogen; methanol as raw materials, MTO line obtained by the yield of ethylene and propylene and the higher than the traditional petrochemical route, propylene and ethylene production The ratio of up to 1.8; naphtha, gasoline and other raw materials for the production of ethylene is not high yield, but the by-product is more abundant.
As we all know, the success of the United States shale gas revolution boosted the country’s natural gas condensate production growth. Ethane as the most concentrated component of the condensate, the output growth is very strong. In 2016, US ethanol production was 460 million barrels, or 23 million tons, up 11.2 percent from 2015. With the growth of shale gas production, it is expected that by 2020, US ethanol production will double to 900 million barrels (45 million tons).

The United States has three years of net exports of ethane, 2016 exports reached 34.27 million barrels (about 1.7 million tons). It is expected that the amount of exports available for 2020 will reach about 10 million tons, and there will still be some margin for export to Canada and other parts of the world, including Canada, Western Europe and India. And supporting the export terminal, large-scale ethylene transport ship construction, will provide protection.
Unlike propane, more than 99% of US ethane is extracted from natural gas, and ethane prices fluctuate substantially in line with natural gas. Oversupply situation led to the US natural gas prices hovering low, but also makes the ethane prices continue to decline, and long-term low, the United States ethane cracking olefin cost advantage highlights. Even in the current low price of China’s coal and the international oil prices in the case of low, ethane cracking is quite cost-competitive olefin production line.
Asian chemical statistics show that China has included the layout and is carrying out pre-argument ethane cracking ethylene project more than 10, ethylene capacity of more than 650,000 tons and million tons. According to the project progress and planning, there will be 2-3 Ethylene Cracking Ethylene Project put into operation by 2020. Part of the project plans to purchase domestic refinery ethane / propane resources, while the purchase of US imports of ethane way to achieve the diversification of raw materials. With the completion of the proposed project, following coal / methanol to olefins, China’s ethylene market pattern ushered in another giant earthquake.
Ethylene cracking ethylene is a mature technology, with low cost, high yield, small pollution and so on. Ethane can be used as an alternative to naphtha cracker raw materials to meet the new ethane cracking project raw material requirements. Following the large-scale export of propane gas in the United States for the coastal area of propane dehydrogenation project, the United States of America Ethane far across the ocean came to China, once again for China’s olefins and petrochemical raw materials to bring innovation and change is expected Step into reality.
At present, for the vast majority of companies that are conducting ethane cracking projects, there is a general concern about the future changes in ethane prices, raw material assurance and other issues that may lead to uncontrollable project costs and the stability of the plant. (2) moderate control of the scale of the project, the source of raw materials diversification; 3. increase the storage capacity, the quality of raw materials, the supply of raw materials, Or warehousing services outsourcing; 4 with a strong joint venture construction projects.
