Wishing everyone a happy New Year, and may their families be safe and healthy. I hope this contribution will inspire further discussion from others – with more people involved, the forum will become even more lively. Haichuan is better with you all; feel free to participate more in discussions on this forum. **********************************************On November 9, 2011, the first domestically produced gas-cooled methanol synthesis reactor successfully passed hydraulic and pneumatic tests at CNNC’s Xinhe Company. The strength and sealing performance of the equipment met all the requirements specified in the design drawings and standards. Currently, the equipment has been shipped to the installation site of Shaanxi Yulin Kaiyue Coal Chemical Co., Ltd. 　　 The air-cooled methanol synthesis reactor was a key research and development project of Xinhe Company in 2011. In the past, such devices were all imported from abroad and were expensive. This air-cooled synthesis reactor was developed on the basis of adapting the British David process. With the same volume as individual units, it requires less material in total, its weight is reduced by nearly 30%, production energy consumption is significantly lowered, while output is greatly increased. 　　 To meet the requirements for domestic design and manufacturing, Xinhe Company organized technical seminars four times during the three-month design process, involving the client and other parties, and resolved various manufacturing challenges such as determining the spatial bending angle of the outer tube, designing the mixture gas tank, assembling the tube bundle, welding the tube sheet to the outer tube, and assembling the tube bundle with the shell. 　　 The successful development of the air-cooled methanol synthesis reactor marks the end of reliance on imported equipment for this purpose; it has enabled the localization of such reactors, and established Xinhe Company as a key player in the manufacturing of air-cooled methanol synthesis reactors in China.
