Dalian R&D Marine Oil and Compressor Oil Projects Pass CNPC Acceptance Review

On January 21 and 22, the Science and Technology Management Department of China National Petroleum Corporation organized experts to hold a project acceptance meeting, at which the 'Development of Two-stroke Engine and Crankcase Lubricants Meeting Marine Emission Requirements' and the 'Development and Applied Research of Lubricants for Localized Key Equipment of Long-distance Natural Gas Pipelines', both undertaken by the Dalian Lubricant R&D Center, successfully passed acceptance.
The project 'Development of Two-stroke Engine and Crankcase Lubricants Meeting Marine Emission Requirements' targeted the International Maritime Organization's limits on fuel sulfur content and the advancement of marine engine technology (larger cylinder bores, longer strokes and the fitting of exhaust gas after-treatment systems), with the aim of developing low-base-number, high-performance marine cylinder oils and system oils. Building on the company's existing additive package technology, and following laboratory simulation of performance and verification in shipboard service tests, the project successfully developed the cylinder oil additive package RHY3534 and the system oil additive packages RHY3512 and RHY3512A. RHY3534 can be used to blend the cylinder oil DCA5040H, while RHY3512 and RHY3512A can be used to blend the system oils DCC3005H, DCC4006H, DCC3008H and DCC4008H. Besides product development, basic research was also carried out under the project: using laboratory simulation and evaluation methods, a load versus friction coefficient curve suitable for linear reciprocating ball-on-disc friction pairs was established, a test method for the asphaltene dispersancy of detergents was set up, and preliminary conclusions were obtained from research into the base number decay pattern of detergents.
The project 'Development and Applied Research of Lubricants for Localized Key Equipment of Long-distance Natural Gas Pipelines' drew on the major science and technology program 'Localization of Key Equipment for Long-distance Natural Gas Pipelines' of Shenyang Blower Works Group, jointly carrying out research on the localization of lubricants for key equipment of long-distance natural gas pipelines and achieving the localization of both the key equipment and its matching oils. The project completed research on the structure and performance of polyether base oils and determined their production process, so that polyether base oils of different viscosities can be produced on demand; it developed KCH220 hydrocarbon gas compressor oil, KCR460 reciprocating natural gas compressor cylinder lubricant and KTGS extreme-pressure combined-cycle turbine oil (centrifugal compressor oil); and the centrifugal compressor oil was tested in four 20MW centrifugal compressor units at the Gaoling compressor station of the West-East Gas Pipeline, accumulating more than 21,000 hours of operation, with results showing that it can meet the lubrication requirements of 20MW centrifugal compressor units. In addition to completing product development, the team also assisted the West-East Gas Pipeline project team in completing the compressor oil service test outline and the Kunlun lubricant oil supply and technical service work specifications for the West-East Gas Pipeline.
Both projects won high praise from experts of the Ministry of Science and Technology; the intellectual property they generated also ranked among the highest, and work such as making the technology tangible was completed successfully. (Reported by Wu Fuli, Dalian R&D Center)
