Maoming Petrochemical's 500,000 tons/year heavy aromatics light chemical industry demonstration unit was successfully put into operation at one time
Thread Content
On May 21, Maoming Petrochemical's 500,000 tons/year heavy aromatics light chemical industry demonstration unit designed and built using the Shanghai Petrochemical Research Institute's complete set of technologies was successfully put into operation at one time and obtained qualified products. The device uses reformed heavy aromatics as raw materials to produce mixed xylene and olefin cracking raw materials, providing strong technical support for oil refining companies to transform into chemical industries. The start-up of the heavy aromatic hydrocarbons lightening project is the Shanghai Institute's "keep in mind the instructions, make new achievements and achieve greater success, and welcome * ”One of the key tasks of the theme operation. The Shanghai Institute's technical team planned in advance and carefully prepared, prepared a material input plan, and docked the plans with relevant technical personnel of Maoming Petrochemical for many times, focused on reminding possible problems during the start-up process, and formulated a detailed emergency response plan. Due to the impact of the epidemic, technical personnel were unable to arrive at the site during the official start of materials feeding. How to achieve on-time feeding and safe and smooth operation of the device faced great challenges. To this end, the technical team of Shanghai Institute of Technology took the initiative and actively sought changes. It established a daily meeting mechanism with Maoming Petrochemical to provide real-time remote technical support. Since May 16, online docking meetings have been held every day to report on the driving situation, analyze existing problems, and arrange the next work plan. On the day of feeding, help complete important steps such as feeding, optimization and adjustment of reaction system process parameters and distillation system through online methods. In the end, the device was successfully fed at one time, and qualified mixed xylene products were obtained after about 30 hours of operation. The main performance parameters of the device all met or exceeded the design indicators. The successful start-up of Maoming Petrochemical’s heavy aromatics and light chemical industry demonstration unit has laid a solid foundation for the industrial transformation of this technology, further broadened the application fields of Shanghai Institute’s aromatics technology, and also provided feasible technical solutions for the “oil conversion” of oil refineries.
Do you know which Chinese project this technology was first used in?
I really don’t know, please tell me{:1_90:}
The first phase of the heavy aromatics lightening project at Jilin Northern Jinjiang Petrochemical Plant was completed and put into operation 2019-12-16 14:03 · Ersanli News Jilin Recently, after nearly 10 months of construction, the first phase of the 120,000 tons/year heavy aromatics lightening project was completed and put into operation at Jilin Northern Jinjiang Petrochemical Plant. It achieved a successful start-up and successfully produced qualified products. This project is the first industrialized device in China that uses the heavy aromatics lightening technology and catalyst of Sinopec Shanghai Petrochemical Research Institute. It is also a landmark project for the plant to promote the transformation, upgrading and high-quality development of Northern Company. After the unit is completed and put into operation, it can produce high value-added aromatics products, provide high-quality saturated light hydrocarbons to the Jilin Petrochemical Ethylene Plant, increase the triene yield of the ethylene unit, reduce ethylene production costs, and create favorable conditions for further developing the comprehensive utilization of heavy aromatics and building a C9 and C10 heavy aromatics deep processing industry chain. At the same time, it will promote the adjustment of the industrial structure of the plant and increase the total economic output. After the project is put into production, it is expected to increase annual operating income by more than 300 million yuan. Since the construction of the project started, the factory has strictly followed the requirements of the two-level companies, actively handled relevant procedures, strengthened coordination, and conscientiously implemented the project manager responsibility system. It has set up various project management groups, each performing its own duties, dividing the work and responsibilities, scientifically organizing, inverting the construction timetable, and clarifying the time nodes of each stage and link. In order to ensure the construction period, the factory organized a competition with the theme of "Strive for a hundred days to achieve great results and make new achievements in project construction" to further clarify responsibilities and refine goals. Based on the principle of "strengthening management, grasping progress, ensuring quality, promoting safety, overall advancement, and key breakthroughs", we will strengthen coordination and cooperation to ensure the safe and steady advancement of key tasks such as design, construction, and supervision. ； Project closing, unit delivery, and production preparation are carried out in an interleaved manner ； Employee training and "three inspections and four determinations" were implemented in advance, and three intensive inspections were carried out on the problems and hidden dangers in process, equipment, safety and environment, fire protection, quality and other aspects during the construction of the project. A total of 179 problems were found, and rectifications were confirmed one by one. The rectification implementation rate was 100%. On November 26, the device started to activate the thermal oil furnace and vacuum system, established a single tower trial operation cycle, and at the same time carried out temperature activation. ； On the 29th, the reaction system was boosted, the hydrogen compressor was started, the spot heating furnace was heated, the secondary reverse temperature was raised, and the oil circulation was introduced. ； On the 30th, the secondary reaction system began catalyst pre-sulfurization ； By December 2, the process flow was all completed and the equipment was operating stably. At 9:00 on December 5, the device was officially put into production. During the critical period of feeding materials, the plant formed a command and coordination team to take command from the front. Experts from the Petrochemical Company's refinery and Petrochemical Shanghai Petrochemical Research Institute were on-site to track, supervise and provide guidance. Managers from the plant's production, equipment, safety, technology, logistics and other departments were at the start-up site around the clock to ensure transportation, achieving a successful start-up.
Provides feasible technical solutions for "oil conversion" of oil refining companies
"Since the construction of the project started, the factory has strictly followed the requirements of the two-level companies and actively handled relevant procedures..." Actively handling relevant procedures simply means producing without relevant procedures, which is a violation, haha
The factory strictly follows the requirements of the two-level companies and actively handles relevant procedures... It is a process with many, many procedures.
