On the eve of New Year's Day, the world's first batch of ethylene glycol made of lignite to meet the needs of users officially went offline at Tongliao Jinmei Chemical Industry Co., Ltd., which ended the history that only countries around the world can only use the petroleum technology route to produce ethylene glycol.
Ethylene glycol is a very important basic chemical raw material. It is mainly used in the production of polyester products, antifreeze agents, unsaturated polyester resins, lubricants, plasticizers, non-ionic surfactants, and explosives. Use is very extensive. According to relevant data, the current global demand for ethylene glycol is more than 20 million tons, of which China’s demand accounts for one-third. At present, the total amount of ethylene glycol produced in the country is only over 2 million tons, and it can only meet the market demand of 20% to 30%. The gap of more than 4 million tons can only rely on imports.
The "coal glycol" technology route and industrial application adopted by Tongliao Jinmei Chemical Industry Co., Ltd. is a set of world first technology with independent intellectual property rights. Its promotion should be able to replace the traditional petroleum technology route to produce ethylene glycol, which will effectively alleviate the contradiction between the supply and demand of China's ethylene glycol products. According to estimates by experts, the production of 1 tonne of ethylene glycol using the petroleum technology route requires about 2.5 tons of petroleum. If the “coal glycol†production technology is used, the annual global savings of oil is equivalent to the newly developed annual output of 50 million. A large oil field in tons.
It is understood that Tongliao Jinhua Chemical's ethylene glycol project has a total investment of 10 billion yuan and a designed production capacity of 120 tons. At present, the first phase of an annual output of 200,000 tons of ethylene glycol projects has been completed, and 1.3 million tons of brown coal can be converted annually. The second phase of the 400,000-ton-per-year ethylene glycol project is actively preparing for the first phase of construction. The first half of this year will be fully started.
Tower Crane
The tower crane is a fixed Crane and has to be mounted On-Site. The Tower Crane presents itself like a vertical metallic structure having a horizontal boom that can turn over an angle up to 360°. From his particular set up, the tower crane is ideal for all king of a high building or high structure construction.
Tower crane includes hammerhead tower crane, Flat Top Tower Crane, luffing type tower crane. Derrick Crane is installed on a stationary foundation.
Tower crane is a common form in urban construction sites. This kind of crane is anchored on the ground, provides an optimum blend of height and lifting capability, which is usually used for building multi-storey city building. Two horizontal jibs jut from center tower, one used lift heavy objects, another is equipped with concrete blocks as a counter weight. Tower cranes are controlled by a driver who either sits in a small cabin at the top of the tower or operates the crane from the ground using a remote control system.
A tower crane is an inverted L-shaped structure that is capable of lifting several tons of weight to precarious heights.
The most striking feature of this crane is that it is self-building and can allow a building to be constructed adjacent to or even around it.
We supply all kinds of tower crane spare parts with good quality, competitive price, short delivery and professional service.
