Oil product quality utilization technology achieves a million-ton leap

 On June 23, the 1 million tons/year diesel adsorption and separation unit of PetroChina Jilin Petrochemical Transformation and Upgrading Project undertaken by China Kunlun Engineering Company successfully completed the process package review, marking the independent innovation technology of "oil product quality utilization" million tons An important step forward for advanced applications
.
Prior to this, the 2 million tons/year AGO adsorption and separation project of Fuhai Chuang Petrochemical Co.
, Ltd.
, also undertaken by Kunlun Engineering, completed the process package review, and the technology will achieve a cumulative technology license in 2021.
Based on the total scale exceeding 1 million tons/year , the single-series license scale quickly exceeded the million-ton level, achieving the "double hundred" milestone, and China has become the only country in the world that has mastered the basic key technology for high-purity separation of heavy hydrocarbon components such as diesel

The transformation and upgrading project of Jilin Petrochemical is a key project for PetroChina to implement the national "dual carbon" strategy and promote the high-quality development of refining and chemical business during the "14th Five-Year Plan" period.
key projects for world-class companies
.
The Fuhaichuang Petrochemical Raw Material Adaptive Technological Transformation Project is the leader of the "100 billion petrochemical" industrial chain planned by Fujian Nenghua Group in the "14th Five-Year Plan" of Gulei Petrochemical Park
.

"This technology separates excess diesel into non-aromatic and aromatic components by simulating the moving bed adsorption separation process.
Non-aromatics are used as high-quality olefin cracking raw materials, which can meet the demand for high-quality raw materials in downstream ethylene units; the adsorption of aromatic hydrocarbons can be achieved by lightening, etc.
By means of producing aromatic raw materials, it will promote the two-way high-quality development of olefins and aromatics
.
After the implementation of the project, it will become the key path for the whole process of enterprise transformation and upgrading and the core device to ensure the supply of high-quality raw materials for downstream chemical plants
.
"Technical person in charge, Kunlun Engineering Company Sun Fuwei, deputy general manager of the New Materials Division, said
.

The process package design of these two projects has the characteristics of high process difficulty, heavy accounting and design workload, heavy tasks, and tight time.
It is necessary to fully consider the flexibility of the overall process connection of the whole plant and the demand for raw materials of downstream devices
.
On the basis of meeting the preparation standards of the process package, it must also have the adaptability of multi-raw material conditions, and conduct in-depth research and optimization of technical engineering scale-up

Faced with the adverse effects of long-term home office work and multi-project cross-over due to the spread of the epidemic, the Kunlun project team cooperated sincerely and overcame difficulties
.
"Only isolate the epidemic, do not isolate the work", and complete various design work in strict accordance with the high quality and high standards of the project's established nodes, including the whole process simulation optimization, pinch point analysis, dynamic simulation of the control scheme, and the design of the patented grid internals of the adsorption tower , The design of the special control system for adsorption, etc.
, and the project documents are delivered on time
.
Design and technology update iterations are continuously coupled and synchronized, and the whole process is optimized and the energy consumption level is continuously improved
.

Sun Fuwei said that "oil product quality utilization platform technology" is used as a "converter" for oil product processing paths, with low energy consumption, flexible and controllable "molecular-level stereotaxic processing" capabilities, organically connecting "oil refining-olefins-aromatic hydrocarbons".
-High-end chemicals" field, making the upstream and downstream processes more optimized and more flexible, which has been widely recognized by the industry
.
It not only meets the needs of high-quality self-supplied raw materials for the cracking unit, but also meets the further reduction of oil products in the future.
At the same time, it reduces the amount of low value-added products such as cracked fuel oil, reduces the amount of coke and hydrogen consumption, and effectively achieves consumption reduction and emission reduction
.
The application field has gradually expanded to light/heavy naphtha, heavy oil/wax oil, coal chemical industry, high-end biomass and other fields
.

It is understood that in 2020, Kunlun Engineering Company and CNOOC Tianjin Chemical Research and Design Institute will cooperate to tackle key problems based on the concept of "molecular engineering", break the technical and equipment barriers in the field of adsorption and separation for more than 50 years, and complete the "world's first diesel adsorption separation process and equipment".
"Successfully Realized Industrial Application" stood out from 145 scientific and technological progress, and won the "Top Ten Scientific and Technological Progress of PetroChina", becoming the only chemical engineering project on the list
.
The complete success of the first application has also received attention and reports from state-level media and units such as CCTV, the Central Government Network, Xinhua News Agency, People's Daily, and the State-owned Assets Supervision and Administration Commission
.

13 CCTV programs to report

"Technology leads the future, innovation drives development"
.
Kunlun Engineering will continue to accelerate the pace of breakthroughs in key technologies, further strengthen technological layout and industrial application, continue to improve the integrated molecular management technology of PetroChina's refining and chemical industry, and accelerate the creation of a source of original "molecular engineering" technologies with world influence, so as to inject high-quality development into the enterprise.
Stronger power, stronger support, and stronger potential
