Subjects of research: rectification processes in an exhaustive string.
Purpose of work: increase of efficiency of process of rectification нефтегазоконденсатной mixes in an exhaustive column by replacement перегретого the water steam applied as the heat-carrier (the steaming agent), on steams heavy faction.
Methods of research: at determination physical and chemical and thermal properties of hydrocarbon raw standard methods of application are used, and at learning of its fractional composition - vehicle. Measurings of temperature, stress, raw and heat carrier discharge rates and other indexes are held by traditional methods. Treating of results of studies is held with use of methods of similarity theory and modelling.
The results obtained and their novelty: for the first time the dodge of an intensification of a mass-transfer is substantiated at rectification of a petrogas condensate mixture for the account of decrease of thickness of boundary films between contacted by phases at use of hydrocarbon steams of in the capacity of steaming agent instead of overheated steam; possibility of an intensification of process of heat change between the steaming agent and a distilled mixture by comparison of coefficients of a convective heat exchange vapour-phase with application of methane, ethane, propane and butane in relation to analogue - water steam is demonstrated; the effective method of rectification of a petrogas condensate mixture in an exhaustive string with application of steams of a high-gravity naphtha in the capacity of the alternative steaming agent allowing is tendered to augment culling of propellant distillates from raw.
Practical value: the elaborated optimum flow diagramme of heat input of steams of a high-gravity naphtha in a bottom part of an industrial fractionation tower allows to increase culling of light distillate fractions from composition of boiler oil on the average on 2,7 % and to diminish the discharge rate of steaming heat carrier on 11,7 %.
Degree of embed and economic effictivity: the technological operating instruction on application of steams of a high-gravity naphtha in exhausting a fractionation tower part is prepared. The elaborated recommendations, on the basis of solution it is production - operating personnel Bukhara petroleum refinery from October, 10th, 2011, are taken over to adapting jointly with specialists of factory to working conditions with the further implementation in production. Expectational annual economic benefit for the account application of a new method of pyrogenic distillation of liquid hydrocarbon mixtures in an exhaustive string Bukhara petroleum refinery compounds 1,3 mlrd. soums per year.
Field of application: the petroleum-refining industry.
