Determination of distillation characteristics of liquid petroleum products by finding the molecular weight fractions of EXPRESS BY DISTILLATION AND APPARATUS FOR DETERMINING THIS

摘要

FIELD: measurement technology.;SUBSTANCE: fraction composition is determined in traditional distillation flask surrounded by isolation protection housing. Flask is equipped with slow-lag thermocouple for measuring temperature of product to be refined in liquid phase and with aid for measuring pressure in front of capillary in hot zone at the output of distillation flask. Density of liquid original oil product can be also measured by piezoelectric method by means of strain resistance gauge. Data from thermocouple and from strain resistance gauge enters personal computer through conversion units. The data is processed by means of special algorithms.;EFFECT: improved efficiency; higher degree of data reproducibility.;19 cl, 9 dwg
