In August, Wuhan was sweltering yet tempered by a gentle breeze, radiating vitality even in the scorching heat. On the morning of the 20th, Mr. Wang Jingxin, Senior Business Director at Honeywell UOP USA, and his delegation drove to Jiangxia District in Wuhan City to conduct an on-site inspection of our company.

On April 28, 2020, our company successfully completed the production and rolled off the line of the key equipment—the tower preheater—for the 1-million-ton-per-year methanol technical renovation project undertaken by China Fifth Ring Engineering Co., Ltd. for Zhongmei Erdos Energy & Chemicals. This equipment has a net weight of 154 tons, a diameter of 2,200 mm, and a length of 18,350 mm. Its shell is made from a composite steel plate consisting of 14Cr1MoR and S32168, while the heat exchange tubes are crafted from S30408 material. Designed using the pressure difference method, the device features a highly complex structure, seamlessly integrating the functions of a heat exchanger and a tower vessel. Specifically, the shell side accommodates synthesis gas, while the tube side handles the reaction gas for efficient heat transfer. The upper and lower spherical heads are equipped with advanced overlay welding, and the assembly includes the top head, tube sheet, and the shell-side cylindrical section.
