We present the results of a laboratory evaluation of the aggregative stability (resistance to stratification and sedimentation) and the thermal stability (constancy of the main qualitative index: the viscosity upon prolonged heating) of a new ZhTK petroleum biocide for impregnation of wood cross...
Control of technological parameters of oil refining processes requires detailed qualitative and quantitative analysis of the hydrocarbon composition of both crude oil and its fractions. Many analytical equipment manufacturers offer systems for such analysis (1 — 6).
An effective method is proposed for the utilization of used motor and industrial oils (UMO and UIO) as additives to diesel fuels. As a result of investigation of diesel fuel L–0,5–40 with 5% of UMO and UIO, the maximum degree of variation was established in the concentration of actual resins...
Recently the structure of the feedstock for petroleum refineries has sharply changed. The fraction of heavy oils with elevated content of heteroatomic compounds has increased in the feedstock (1). The selection of optimal conditions for refining such feedstock depends on the extent and depth of...
One of the most critical solutions of ecological problems in Russia is associated with the replacement of toxic lead-containing antiknock agents in the production of automotive gasolines (1, 2).
We use mathematical methods for optimization of the conditions for obtaining C 6 — C 8 aromatic hydrocarbons from low-molecular C 2 — C 5 hydrocarbons. This is an important problem, the solution of which will facilitate reduction of the number and cost of trials performed (1, 2).
This institute has developed efficient devices for dealing with excessive foaming in gas chemisorption cleaners. Foam suppressors of PL boat type are used to restrict the height of the foam layer arising from bubble plates, while VNIIUS–14 contact devices are used that operate in dispersed film...
