【In-depth Discussion on HaiChuan Modular Installation】16 Huizhou No.2 Refinery: China’s first set of modular vacuum distillation heaters and ethylene cracking furnaces
Thread Content
According to Sinopec News Network (Wang Guigen), on December 13, 2015, at the site of the Huizhou Refinery Phase II expansion and upgrade project as well as the million-ton ethylene production project, which were under the general contracting of Engineering Construction Co., Ltd., the atmospheric and vacuum heating furnaces and ethylene cracking furnace modules designed by this company were installed in place. This marked a significant achievement in SEI’s modular technology for industrial furnaces, representing another step forward in the design, manufacturing, and installation of such furnaces toward meeting the international trend of providing them as large-scale, prefabricated units. The following images and text come from online searches and are provided for discussion. Are furnace devices more modular? Let’s discuss this -------------------------------------------------------------------------------- The atmospheric furnace, vacuum furnace, combined platform, and flue gas waste heat recovery system of the atmospheric and vacuum distillation units in this project, as well as the cracking furnace in the ethylene plant, all adopt a deep modular design. Among them, the largest module of the atmospheric and vacuum distillation unit measures 27.2 meters in length, 6.9 meters in width, 8.95 meters in height, and weighs 300 tons ； The largest module of the ethylene cracking furnace is 28.2 meters long, 12 meters wide, 7.5 meters high, and weighs 380 tons. During the design process, the specialists in pyrolysis furnace equipment and structure worked closely together, holding numerous discussions to address design challenges and reviewing and modifying the TEKLA models. In particular, the structural engineering team overcame technical challenges such as the design of large-sized modules and the design of long-span spans without interior columns, ensuring seamless transportation and installation of the entire modular structure of the large-scale pyrolyzer.
To ensure the stability of the furnace structure during transportation, all modules are shipped by land and sea, with loading and unloading carried out using SPMTs (self-propelled hydraulic flatbed trucks) during land transport. During the lifting process, taking into account the large size and heavy weight of the pyrolyzer modules, the technical staff devised a plan to use SPMT hydraulic jacks to position the lower modules, while cranes were used to lift the upper modules – a method that is being used for the first time in China. The modular design of the atmospheric and vacuum distillation heaters as well as the ethylene cracking furnace in Huizhou Phase II represents a first in China in terms of module installation dimensions, equipment weight, difficulties associated with sea and land transportation, as well as the complexity of lifting and installing large-scale equipment. Through the modular application of industrial furnaces in Huizhou Phase II, SEI has accumulated valuable design and engineering experience, overcoming many challenges associated with the large-scale modularization of industrial furnaces, thereby laying a solid foundation for the widespread adoption of SEI’s overall modular furnace technology.
New breakthroughs in modular technology for ethylene cracking furnaces March 19, 2015, 15:41:50 China Plastics Machinery Network Views: 7152 【Technology Updates from China Plastics Machinery Network】On March 10, the modular technology for ethylene cracking furnaces developed by Sinopec Engineering Construction Co., Ltd. passed the expert evaluation organized by Sinopec’s Major Projects Office. Experts believe that this technology has developed a modular form for the steel structure in the radiation section as well as a method for installing the radiation coils, which not only ensures the quality of equipment installation but also significantly reduces the construction time; overall, this technology is at an internationally advanced level. This technology has been applied in Malaysia’s Titan project, the Fujian refining and chemical industry capacity expansion project, and the Yangzi Petrochemical renovation project. Throughout its application, a set of proprietary technologies for the modular design, manufacturing, and installation of cracking furnaces has been developed; to date, this technology has yielded 5 **patents.

In terms of modular technology, Sinopec really needs to catch up. It has strong engineering companies, capable installation units, powerful lifting and transportation firms, as well as a robust project market. However, when it comes to the practical application of modular technology, it lags behind CNOOC, CNPC, and even some private engineering companies. If Sinopec aims to become an international, strong company and establish a solid foothold in the global petrochemical market, it must keep up with modular technology in order to meet the demands of building projects overseas.
A strong domestic market; excellent coordination capabilities
What is the relationship between Sinopec engineers and Luoyang Institute?
I don’t understand the meaning of the question: this person (engineer) and the organization (Luoyang Institute)? Is the question: What is the relationship between Sinopec Refining & Chemical Engineering Company SEG and Luoyang Institute LPEC? Answer: LPEC is a subsidiary of SEG, which was formed in 2012 when Sinopec integrated its engineering construction capabilities. It is currently ranked first in China in terms of engineering services provided to the refining and petroleum industries, and it is among the top ten general contractors in the world. SEG also includes well-known companies such as SEI (Sinopec Engineering Company), LPEC (Sinopec Luoyang Engineering Company), SSEC (Sinopec Shanghai Engineering Company), SNEC (Ningbo Engineering Company), SNEI (Nanjing Engineering Company), Sihua Jian, Wuhua Jian, Shihua Jian, Sinopec Heavy Lifting Company, SGEC (Guangzhou Engineering Company), and so on.
