China drying wire Reuters Southwest Chemical Industry Research and Design Institute developed the esterification of acetic acid hydrogenation of ethanol technology projects in Chengdu by the experts organized by the Sichuan Provincial Science and Technology Department. Experts believe that this technology has low energy consumption, low cost, advanced technology and equipment, and excellent catalyst performance. The promotion of this technological achievement can not only solve the problem of serious overcapacity in the acetic acid industry, but also enable coal chemical industry to replace the grain route to produce bulk energy chemicals. It is reported that the Southwest Research Institute has been developing technology for the hydrogenation of acetic esterification and its catalysts since 2008. It has made breakthroughs in the hydrogenation of acetic acid to ethanol, and has applied for six invention patents and has formed independent intellectual property rights. New processes and new technologies. According to reports, this technology has for the first time enabled coal chemical technology to replace the "grain route" for the production of fuel ethanol, and developed a complete set of acetic esterification, hydrogenation, and ethanol technologies with independent intellectual property rights. It was verified through small-scale tests, model tests, and pilot tests. The feasibility of its process route, and took the lead in the domestic development of 200,000 tons / year scale of industrialization demonstration, the current process software package development has been completed. At the same time, the special catalyst developed by it has high activity, good stability and high selectivity. The conversion rate is as high as 97% and the selectivity to ethanol is more than 98%. The catalyst and process technology are also applicable to the production of ethanol from crude ester hydrogenation, which simplifies the traditional ethyl acetate distillation process of acetic esterification and greatly reduces the energy consumption of purifying ethyl acetate. The hydrogenation catalyst has a high conversion rate in one pass and vice versa. With less product, the product has high purity and low energy consumption for separation. In addition, compared with direct hydrogenation of acetic acid to ethanol, this technology avoids equipment corrosion, high equipment investment, and high catalyst costs. Ethanol produced by this technology is significantly lower than the traditional grain fermentation method, and it has a strong market competitiveness. It is understood that the cost of producing ethanol by grain fermentation methods is as high as 7,500 to 8,000 yuan per ton, while the production of ethanol from petroleum ethylene routes is due to the shortage of oil resources in China and the increase in oil prices, resulting in higher production costs. The cost of ethanol produced using this technology is about 6,100 yuan/ton, and the cost is competitive. The fixing angle of a Tower Crane refers to the angle at which the crane is secured to its base or foundation. It is important to ensure that the crane is properly fixed at the correct angle to ensure stability and safety during operation.
It is important to follow the manufacturer's guidelines and recommendations when setting the fixing angle of a tower crane to ensure safe and efficient operation. Improper fixing angle can lead to instability, tipping, or other safety hazards.
Tower crane fixing angle is connected between tower body and concrete foundation. Usually, the model of fixing angle is based on the tower crane Mast Section, such as 1.2m s24 mast section, 1.6m L46a1 mast section, 2.0m l68b2 mast section.
Fixing angle is used for connecting of tower crane foundation and tower crane body. Usually the fixing angle is fixed inside the concrete foundation. However, there is one type of tower crane fixing angle which is reusable type. The reusable type fixing angle could be removed from the foundation after tower crane disassembly.

The fixing angle of a tower crane is typically determined by the manufacturer and specified in the crane's operating manual. It is usually set at a specific angle to provide optimal stability and load capacity for the crane.
The fixing angle can be adjusted during the initial installation of the crane to ensure it is level and properly aligned. This is typically done using leveling jacks or other adjustable components at the base of the crane.
