PetroChina's oily sludge treatment technology is internationally advanced

Realize reduction, resource utilization, and harmless treatment

Realize reduction, resource utilization, and harmless treatment

Sinochem News reported on June 17, news from the Research Institute of Petrochemical Industry that the oily sludge pyrolysis-high temperature thermal oxidation co-processing technology and industrial application project passed the scientific and technological achievement appraisal organized by the China Petroleum Science and Technology Management Department
.

Experts of the Appraisal Committee agreed that the scientific and technological achievements reached the international advanced level and suggested that the promotion and application of the technology should be accelerated

The appraisal committee is composed of 7 experts, including Academician Xu Chunming of China University of Petroleum and Deputy Chief Engineer Zhou Yuexi of the Chinese Academy of Environmental Sciences
.

This technological achievement was completed by the cooperation of the Research Institute of Petrochemical Industry, the Research Institute of Safety and Environmental Protection Technology and Xi'an Shiyou University

At present, China's petroleum production and processing industry produces more than 8 million tons of oily sludge each year.
The output process includes oil-based mud, large tank sedimentation sludge, ground oil sludge and sludge from the oily sewage treatment process
.

Different types of sludge are complex in nature and difficult to treat.

The research team comprehensively considered the three aspects of oily sludge reduction, resource utilization, and harmlessness.
Using biomass as an additive, through interface control and particle gradation adjustment technology, the high-efficiency solid-liquid of high-water sludge and aging oil was realized Separation; Using modified clay as a catalyst, the low-temperature catalytic pyrolysis technology of oily sludge has been developed to realize the recycling of crude oil resources; in order to eliminate the impact on the environment, based on the pyrolysis of oily sludge, pelletized fuel has been developed Preparation and high-temperature thermal oxidation treatment technology to realize the harmless treatment of oily sludge
.

Through equipment development, the project realized the industrial application of processing technology

According to reports, the project has completed an industrial plant with a processing capacity of 300 tons per day in 2016, and has carried out related businesses such as oilfield sludge treatment
.

From 2017 to 2020, the cumulative amount of sludge treated by the project will be 370,400 cubic meters

The appraisal committee listened to the detailed report of the project team on the overall idea of ​​the scientific and technological achievements, the key technologies formed, the innovation points, the important achievements obtained, the application of the results, and the analysis of economic and social benefits.
After inquiries and discussions, the project was finally confirmed The results have reached the international advanced level, and at the same time, suggestions have been made for the promotion of the technical results
.

The technical project team conducted research and deployment on the next step, clarified the division of responsibilities, and determined the time node to ensure the smooth progress of the later industrial promotion of the technology
