Latest updates on Yulin Chemical’s 1.8 million tons/year ethylene glycol project! Author/Source: Shaanxi Coal Group Date: 2020-04-02 Clicks: 46 On March 29, the spherical head and shell-side cylinder of the ethylene glycol synthesis tower – a key equipment component for Yulin Chemical’s 1.8 million tons per year ethylene glycol production project – were successfully transported to the large-scale equipment welding and assembly facility at the project site, marking the entry of this project’s equipment into the phase of on-site assembly and manufacturing. The ethylene glycol synthesis tower for oversized equipment was manufactured by Zhanghua Machinery (Suzhou) Reassembly Co., Ltd. What is being delivered this time are the spherical head SR3114×75 for the ethylene glycol synthesis tower, as well as the shell-side cylinder IDN6200×110×2632. There are two heads in total, one at the top and one at the bottom; each head weighs 45 tons and is composed of 8 segment pieces and 3 end rings ； The shell section per cylinder is divided into 2 pieces, with a thickness of 110 mm. All the equipment delivered to the site is pre-fabricated and pre-assembled by the manufacturer to meet the required standards, before being transported to the large-scale assembly and welding facility at the project site for further assembly and welding. Next, Jiangsu Yongda Chemical Machinery Co., Ltd., Lanzhou Lanshi Heavy Equipment Co., Ltd., and Xi’an Nuclear Equipment Co., Ltd. will also move into the company’s large-scale equipment welding and assembly plant one after another to commence intensive equipment manufacturing work. It is understood that the synthesis towers for the 1.8 million tons per year ethylene glycol project are equipped with 12 units, each with a diameter of 6,200 mm and a length of 15 meters. These towers consist of end caps, shell sections, tube sheets, and heat exchange tubes, and the weight of each unit is 389 tons. It is worth noting that the diameter of the tube sheet of this equipment is 6400 mm, with a thickness of 220 mm; the weight of each individual tube sheet blank reaches 110 tons, setting a record for the largest tube sheet of its kind in China. Additionally, all 16,055 heat exchange tube holes on the tube sheet were manufactured using large-depth hole drilling machines, and the processing equipment and techniques employed are at the highest level in China.
