As one of the core equipments of the main process of low-temperature methanol washing, the equipment undertakes the task of removing hydrogen sulfide and carbon dioxide from the process gas. The design pressure is high, the operating temperature is low, the raw materials and design technology are high, and the manufacturing process is difficult. Since the 1980s, domestic technology and steel sheets have been introduced into the manufacturing and processing of such equipment in China. After extensive innovation, Wuhan Donghai Petrochemical Heavy Equipment Co., Ltd. developed the first low-temperature methanol-washed hydrogen sulfide/carbon dioxide absorption tower in China using domestically produced 08Ni3DR steel sheet, and successfully applied it to the 1.8 million tons/year coal-to-methanol project of Erdos Jinchengtai Chemical Company in Inner Mongolia (1 In the period of 600,000 tons/year, the application of 08Ni3DR steel in the manufacture of low temperature pressure vessels was realized. The results of the 120-day trial run show that the absorption tower is superior to the design value in terms of comprehensive steam consumption and washing yield, and the comprehensive cost of full-load operation is lower than other similar products in the world. The light source (which is often also called a fiber optic projector or fibre optic illuminator) provides the illumination to any fibre optic lighting system. They contain the lamp or LED and any additional control gear to provide special lighting effects.

Light sources are the only part of a fibre optic system which contains electricity, and they are the only part that, depending on the type, can get warm to the touch.
Low-temperature methanol washing process fully realizes localization
The core non-standard equipment hydrogen sulfide/carbon dioxide absorption tower of the -101 °C low-temperature methanol washing device manufactured by Wuhan Donghai Petrochemical Heavy Equipment Co., Ltd. has recently been successfully operated on the coal-based methanol plant of Erdos Jinchengtai Chemical Company in Inner Mongolia. It marks that the low-temperature methanol washing process in China has been fully realized in localization, and provides the physical basis and basic data for the revision of the national standard "low-temperature alloy steel plate for pressure equipment".
