By use of caustic washing electrofining method to decrease the acidity of straight run diesel oil,serious diesel oil emulsification problem can occure often.
Effective, rapid, non volatile, non conflagate, less insitation, recovery use, it is an ideal substitute of gasoline and diesel oil using for cleaning.
YNF30 Jackdrill with caunter-cylinder is developed with the aim at resolving the problem existing in the deep-hole drilling by single-cylinder hand diesel jackdrill.
The quality of diesel oil producing was advanced by isomery pour point depression technique applying in hydrogenation unit in Harbin Petroleum Company Branch of PetroChina.
A new type of smokemeter of fluid-separating and transphotometry was developed.The meter is precise,portable and simple in structure,is appliable to dynamic determination of diesel exhaust.
Abstract: The deposition characteristics of diesel engine particles under the effect of thermophoresis force in cooling tube have been studied by the method of parameter analysis in this paper.
