On August 29, Sinopec announced that my country's largest carbon capture and use and sealed industry chain demonstration base, the first million-ton CCUS project in China- "Qilu Petrochemical-Shengli Oilfield Million-ton CCUS Project" The operation marks that the CCUS industry in my country has begun to enter the middle and rear sections of the technical demonstration -mature commercial operations.

Taking the CCUS project as an opportunity, based on the new stage of development and implementing the new development concept, we can effectively fulfill the responsibilities of the central enterprise around carbon peaks, carbon neutrality, and in accordance with Sinopec's "one base, two wings and three new" industrial structure, accelerate the formulation and implementation of implementation and implementation Carbon peaks, carbon neutralization and strategic paths. Actively promote the transformation and upgrading of traditional business, continue to promote low -carbonization of energy structure, continuously improve the level of energy efficiency, and explore technologies such as carbon dioxide preparation of high -value chemicals.

"Qilu Petrochemical-Shengli Oilfield Million-ton CCUS project is hailed as the" Industrial Forest ". After production, it can reduce the carbon dioxide each year by 1 million tons, which is equivalent to nearly 9 million trees and nearly 600,000 economy cars for 1 year. It can effectively promote fossil energy cleaning, large -scale energy sources, and low carbonization of production processes, forming experience development experience of replicable and promoting CCUS industry. "Han Feng, deputy chief engineer of Sinopec Group and representative of Qilu Branch, and party secretary of the party committee.

Establish a "artificial carbon cycle" model to achieve carbon dioxide into treasure

On July 5, 2021, Petrochemical announced that it opened the first million-ton CCUS project construction in my country-Qilu Petrochemical-Shengli Oilfield CCUS project. This is the first million -ton CCUS project in China, and it is also the largest domestic CCUS industry chain demonstration base and benchmarking project. It is of great significance for building a "artificial carbon cycle" model.

"CCUS is one of the key technologies to reduce carbon dioxide emissions. Catal the carbon dioxide discharged during the production process and purify the new production process reuse and seal, which can directly reduce carbon dioxide emissions." Li Haiqiang, manager of Qilu Petrochemical Second Chemical Fertilizer Factory.

The carbon dioxide tail gas discharged by the gasification device of Qilu Petrochemical's second chemical fertilizer plant belongs to high -quality carbon dioxide resources, with a purity of 90%. In the carbon capture session, Qilu Petrochemical recovered carbon dioxide in the exhaust of gasification device through liquefaction purification technology; in the carbon utilization and sealing link, the victory oil field injected carbon dioxide into oil wells to greatly increase oil harvesting. Achieving underground storage with mineralization, it really becomes waste into treasure.

The comprehensive utilization of carbon dioxide is conducive to the reduction and environmental protection of greenhouse gases, and is an important measure to reduce the impact of greenhouse gas on environmental impact. "Carbon driving oil" is an important technical support for carbon neutrality.

In accordance with the national "double carbon" target strategic deployment, Qilu Petrochemical implemented the group company's work requirements, and quickly launched the construction of millions of tons of carbon dioxide recycling projects. Establish 4 working groups including project leadership group, set up material procurement and engineering design, and regularly hold special meetings to study and solve problems in the process of promoting the project, formulate practical measures, and make every effort to promote the early completion and early results of the project.

Gathering the power of manufacturing in China, the localization rate of equipment reaches 100%

After the construction of the project was fully launched, Qilu Petrochemical strengthened the operation management of the project, deepened the research of carbon dioxide capture technology, continued to optimize the carbon dioxide capture process process, continuously reduced the carbon emissions and capture costs of the project, and gradually expanded the project application scale.

According to raw materials, product gas and storage and transportation methods, the technical solution of liquefied purification purification is determined. In order to reduce the cost of operating energy consumption and liquid carbon dioxide products, the project adopts a large amount of energy -saving technologies such as residual heat recovery and residual pressure recovery to achieve the ladder use and effective recycling of energy, greatly improve the efficiency of energy utilization, reduce the "secondary carbon emissions" in the operation process Essence

All participants are always guided by "control safety, quality, and improve progress" to improve the construction efficiency of the project. The owner, the construction party, and the supervisory party coordinated the combat to overcome the difficulties of the epidemic, winter construction and long -term ordering. On the premise of ensuring safety and quality, they broke the routine. The model is continuously constructed day and night, competing for time, gathers Chinese manufacturing forces, and guarantees the supply of material construction. The localization rate of CCUS project equipment has reached 100%.

In order to accelerate the construction of the project, with the support of the relevant departments of the headquarters, Qilu Petrochemical adopted the project management leadership group+project site management department+supervision+contractor's management model to build a complete organizational system, covering engineering design, equipment selection purchases , Construction and Construction and other links.

The members of Qilu Petrochemical leaders and relevant departments have repeatedly supervised and guided at the construction site to coordinate and solve the problems in construction. "The construction project implements grid management. The three construction areas are divided into 5 grids, and the grid length is set up. The whole process is responsible for the design, construction, construction, and driving work of the unit device." Qilu Petrochemical Second Geng Tao, director of the gas joint workshop of the fertilizer plant.

On January 29, 2022, only 96 days were used, Qilu Petrochemical-Shengli Oilfield CCUS project was fully completed.

After the project was completed, Qilu Petrochemical accelerated the preparations for construction, set up a team of experts, and deduced the problems that could occur during the driving process, formulated protective measures to ensure that the device was affordable, stable, long -term, and high benefits.

During the Spring Festival, the project team members gave up their reunion with their family members, and they were prepared to make work together. At the same time, coordinate the construction of the project, and the task time is accurate to the hour. Production preparations, three investigations and four fixes, construction harvesting and employee training simultaneously, promote all work at full speed.

On April 4th, the first tanker carbon dioxide product was shipped to the factory and was shipped to the Shengli Oilfield Injecting Center, marking that the CCUS project was successfully produced in the upstream Qilu Petrochemical carbon dioxide capture device.

After the project was put into operation, the liquid carbon carved by Qilu Petrochemical was transported to the victory oil field by the road to the Shengli Oilfield. In order to do a good job of product loading and unloading, Qilu Petrochemical and Shengli Oilfield strengthened communication and discussed the daily output, tank capacity and car loading conditions of the product, and established an online sales process. Carbon dioxide is sold in time to prepare for the factory.

"The CCUS project that belongs to Sinopec, Qilu Petrochemical and Shengli Oilfield has a natural advantage. In the next step, according to the uniform deployment of the group company, it will be completed as soon as possible to apply the carbon dioxide transportation pipelines from Qilu Petrochemical to Shengli Oilfield to further reduce the cost of transportation and build it into it. Copy -promoted CCUS full industry chain demonstration base and benchmark project. "Wang Yuliang, general manager of Sinopec Group Qilu Petrochemical Company.
