Shared from the internet: The first unit of Dushanbe Petrochemical’s ethane-to-ethylene plant was successfully commissioned on its first attempt. Chemical Online, 1 week ago. China National Petroleum Corporation announced that on April 15, the air separation and air compression units of Dushanbe Petrochemical’s Tarim ethane-to-ethylene plant were successfully commissioned, producing qualified nitrogen; this was the first unit of this ethane-to-ethylene project to go into operation. The Tarim ethane-to-ethylene project of Dushanzi Petrochemical Company represents the first application of \"local resources and independent technology\" in China’s ethylene industry. It serves as a model for promoting the high-value utilization of domestic natural gas resources and reducing reliance on foreign ethylene production technologies; it has been designated by the National Development and Reform Commission and the Ministry of Industry and Information Technology as a demonstration project for ethylene cracking. Completion is scheduled for June 30 this year, with operation expected to begin on September 30.
On March 15, the air separation and air compression units for the ethane-to-ethylene project at Dushanzi Petrochemical Company were successfully handed over. This is the first auxiliary production unit of this project to be completed; once handed over, it will facilitate the instrument calibration and pipeline purging for various units. The air separation and compression unit primarily supplies nitrogen and instrument air to ethylene cracking units, copolymerization facilities, and other auxiliary systems. This device utilizes mature domestic processing technologies and gives priority to domestically produced equipment; it features improved instrument control, reduced labor intensity, as well as enhanced management and safety monitoring capabilities.
At around 7:30 a.m. on April 21, the first light of dawn appeared and the weather was cool. At the east and west gates of the ethane to ethylene project, construction workers flocked to the site. At present, there are over 7,200 construction workers employed by the main contractors on site, and the overall progress of the project has reached 93.67%. At around 8:10, each construction unit held a pre-shift safety briefing on a team basis to assign the tasks for the day. After receiving the tools and equipment, everyone headed to their respective construction sites. For a short period of time, the construction site was filled with the sounds of welding, grinding, and lifting, presenting a bustling scene. Tang Guiquan, team leader of Team 117 in the 600,000 tons/year ethylene plant project department of China National Petroleum Corporation’s Sixth Construction Company, said that during the installation of the cracking furnaces, they divided the 1,100-ton steel structures of the 5 furnaces into 35 modules, assembled them on the ground first, and then lifted them as a whole, just like building blocks. This approach allowed them to complete the work 20 days ahead of schedule and saved millions of yuan in labor costs.

Guess everyone, what device is this?
Which one is the first, Tarim or Changqing? All claim to be number one in \"ethylene production from ethane\".
I don’t think so; Xinpu Chemical’s ethane cracking plant has been in operation for three years already.
The ground torch doesn’t seem very large.
