On July 22, the 1 million-ton/year hydrocracking unit was successfully put into production and produced qualified naphtha, diesel and other products, marking the completion of the complete reconstruction project of Dagang Petrochemical's 5 million tons/year. A brand-new page in the history of enterprise development has also laid a solid foundation for building pioneer-type refinery companies.
History is at this moment. This is another milestone in the history of Dagang Petrochemical Company's development. It not only records the footsteps of Dagang Petrochemical Company in its determination to forge ahead and seeks development, but also bears the great vision of Dagang Petrochemical's employees for tomorrow.
Increased supporting processing capacity In 2003, Dagang Petrochemical Company, with the support of CNPC, decisively took measures such as shutting down inefficient and high-efficiency devices and scrapping idle assets, and went light, with annual sales revenue surpassing the 5 billion yuan mark for the first time. Lost three years of loss-making hats, achieved profitability, and won a rare opportunity for development and reconstruction projects.
Since 2004, Dagang Petrochemical Company has invested a total of 1.642 billion yuan and has implemented a phase-two project of 5 million tons/year of complete supporting transformation. Newly constructed 1 million tons/year of delayed coking, 1 million tons/year of hydrocracking, 40,000 standard hydrogen production equipment, reformation of 5 million tons/year of atmospheric and vacuum distillation, and 1.6 million tons/year of catalytic cracking. At the end of 2004, the first phase of the project was completed and put into production. In July 2008, the second phase of the project was completed and put into production.
The full operation of the project has enabled the company's processing capacity to jump from 2.5 million tons/year to 5 million tons/year, and achieved a total throughput of 5 million tons/year. The primary and secondary processing structures are more reasonable and the processing methods are more complete. The processing flow is more smooth, the processing adaptability and flexibility are continuously enhanced, and the processing efficiency, competitive strength and anti-risk capability are significantly improved.
Won the initiative to build 1 million tons/year of hydrocracking and 40,000 pounds/hour hydrogen production plant is a key project of the company's 5 million tons/year perfect supporting transformation project, with 238 units (sets) of equipment, most of which are equipment The materials are imported from abroad, the introduction cycle is long, the procurement cycle is short, and the technology content is high. In particular, the current manufacturing tasks at manufacturing plants in the domestic and foreign manufacturing industries are unprecedentedly full, resulting in the continuous extension of equipment manufacturing cycles and increasing the difficulty of material procurement.
To this end, the company plans in advance to instruct the e-commerce department to speed up the procurement of orders for long-term, long-term, and key equipment, and do its utmost to reduce the impact of equipment arrival on the project schedule. In the past two years, the company’s relevant leaders, technical departments, and e-commerce staff have gone to the manufacturers in Qiqihar, Harbin, Shenyang, Fushun, Dalian and other places for more than 20 times. They include reactors, high-pressure vessels, high-pressure air coolers, and high-pressure heat exchangers. The production status of the core equipment is understood and the overall availability is mastered.
Hydrocracking reactors are the key equipment for the most complex process and longest manufacturing cycle. In order to ensure the completion of the manufacture of the reactor as soon as possible, the company’s leaders made several trips to Dalian to communicate and coordinate. At the same time, the Assistant to the General Manager Zuo Wendou led the personnel of the Engineering Management Department to station at the Dalian Yizhong Manufacturing Base more than two months in advance to carry out supervision work.
In order to maximize the manufacture of the reactor, the company's supervisory personnel actively communicated with the manufacturing unit personnel to coordinate and solve the problems arising in the manufacturing process, which effectively guaranteed the manufacturing schedule and manufacturing quality. At 11 o'clock on the morning of August 28th, 2007, the hydrocracking reactor with a height of 44 meters and a total weight of 852 tons successfully hoisted successfully, marking an important progress in the construction work of the 1 million-ton/year hydrocracking unit and winning the Promote the initiative of project construction progress.
At the same time, the company also advanced the training of new installation employees, organized the process of learning new devices and operating knowledge, strengthened the DCS system operation drills for new installation operators, and went to Daqing Petrochemical and other advanced brother companies to practice.
Strengthening scientific management of construction Because of the tight construction time and heavy tasks, Dagang Petrochemical has taken measures such as dynamic management of project plans, evaluation of construction units, continuous inspection of safety supervision, spot inspection of project quality supervision stations, and follow-up design of the entire project, which has been comprehensively strengthened. Construction construction, construction quality and management of construction teams.
In order to strengthen the implementation of the six anti-violence bans, the company’s safety management personnel ordered the suspension of work and rectification, and punished them in accordance with the relevant regulations of the company, for the phenomenon that the hot work, large equipment lifting, and scaffolding erection on the site could not meet the safety requirements. At the same time, according to the "construction unit assessment rules" assessment of the construction unit, as the basis for the assessment of year-end access qualifications, effectively regulate the construction unit's operation management. In addition, construction personnel who fail to pass the safety education in the factory are not allowed to enter, and the safety of entering the factory is strictly controlled.
In order to further enhance the safety awareness of the project participants, the company has taken the lead in introducing the management concept of DuPont's safety experience sharing. When each engineering conference is held, the participants will tell safety stories and ring safety alarms at all times to enhance the attendees’ safety consciousness. During the construction work, the project construction personnel carried out an investigation and inspected cranes, wire ropes and other equipment and appliances carefully and carefully calculated each time, successfully completing the hoisting tasks for large-scale tower cranes and other equipment.
In daily construction, company safety supervisors also use follow-up management to strengthen the follow-up supervision of the construction process. In actual work, they will be “three-diligenceâ€, that is, diligently look at the construction operation process, diligently check the results of construction operations, and diligently say that the construction operation operation is strictly prevented. "Three violations" occurred to ensure the safety of the construction site and the achievement of zero-accident goals.
Controlled operation promotes successful production In order to ensure the success of the new installation at one time, Dagang Petrochemical Company has established a start-up leading group in accordance with the requirements of the “four-in-law†work law, breaking down the tasks at each level and implementing the responsibilities step by step.
In the process of “three inspections and four determinations†and the handover of the project before the CCCC, the quality of the project construction was strictly controlled. The company organized various experts to form a joint inspection team and set up professional components such as process, equipment, electrical appliances, instruments, safety, and quality. Check. For all parts of the process, equipment, pipelines, electrical, instrumentation, bolt gaskets, one by one investigation, detailed records, and the use of advanced chromatographic detectors for key materials for material analysis, found that does not meet the design requirements, and resolutely replace Corrective actions provide hardware protection for safe operation of the device.
During the pressure testing and testing of the 1 million-ton/year hydrocracking unit, the second joint workshop divided the plant into five areas: cold highs, hot highs, furnace reaction zones, high pressure heat exchangers, and compressors. Employees in the squad were launched to carry out a comprehensive network-wide investigation. Employees checked from each pipeline, every valve, and every equipment, and missed one leak point and one hidden danger. They detected and processed a new hydrogen body, a large reactor cover, and a D-103 safety valve crossover line. There are a total of 106 leaks in the size of the valve body.
During the production period, the employees of Dagang Petrochemical carried forward the iron spirit of fearlessness and tiring, continued to fight more than 30 days and nights, united and cooperated, from the installation of the catalyst to the furnace of the reformer, from the temperature rise of the reaction system to the emergency relief pressure. In the experiment, from the catalyst sulfiding to the switching of raw materials, 100 steps and new operating procedures of the device were strictly executed at each step, so that the operation was step by step signed and confirmed, and step by step was controlled, which effectively ensured that the device was successfully started once.
The “Sunshine†Engineering Company was established to establish a leading group composed of members of the Party and government’s main team in accordance with the “Notice on Launching the Supervision and Management of the Investment Management of the Second Phase of the 5 million-ton/year Supporting and Transforming Project†document. There are five working groups under the Project Bidding Examination Team, Construction Management Examination Team, Material Purchase Examination Team, Contract Management Examination Team and Investment Management Examination Team.
In order to prevent corruption during the construction process, Party committees and disciplinary inspection and supervision departments of Dagang Petrochemical Company also issued special opinions on strengthening the construction of party style and clean government in the process of project construction, and formulated and promulgated the "Restructuring and Expansion of Eight Inaccuracies". It stipulates that the company’s mid-level management personnel should establish “Taiwan-Taiwanese†rules for honesty and self-discipline “six, twenty inaccuracies†and send them to middle-level management personnel and participate in the perfection of the distribution and reform engineering personnel, and place them on the desktop. Use disciplinary rules to restrain and alert cadres.
The company's supervisors also successively participated in tenders and tenders for major engineering projects and large-scale procurement of materials and equipment, and oversaw the entire bidding and tendering conference. Individual valve and heat exchanger manufacturers with poor reputation, poor performance, limited manufacturing capacity, and poor after-sales service are to be retired, and the quality of the product is controlled from the source.
Xiongguan Dadao really like iron, but now the pace to go from scratch. 5 million tons / year complete supporting transformation of the first and second phase of the project completed and put into operation, further strengthened the confidence of the development of Dagang Petrochemical Company. Standing at a new starting point, employees of Dagang Petrochemical Company are motivated by the spirit of Daqing and the spirit of the Iron Man, step by step, and develop the open east wind in the Binhai New Area, and strive to build Dagang Petrochemical into a vanguard-type refinery company for PetroChina. Build a comprehensive international energy company to make new contributions!
