MICROWAVE TECHNIQUE FOR DETERMINING MOISTURE CONTENT OF LIQUID HYDROCARBONS AND FUEL

摘要

FIELD: chemistry. ^ SUBSTANCE: reference liquid sample with real and imaginary permittivity much higher than that of the analysed hydrocarbon is taken and placed in separate intertwined pipes. The analysed and reference liquids are heated with microwaves while rotating the pipes at not less than 3 rpm. Relative bulky moisture content of the liquid hydrocarbon is determined using the formula where öt1e is the heating temperature of the liquid hydrocarbon with known relative bulky moisture content V0; öt2e is the heating temperature of the reference liquid sample together with the liquid hydrocarbon with known relative bulky moisture content V0; öt1 is the heating temperature of the liquid hydrocarbon with unknown relative bulky moisture content V; öt2 is the heating temperature of reference liquid sample together with the liquid hydrocarbon with unknown relative bulky moisture content V, wherein the initial temperature values of the samples before microwave heating during measurements öt1e, öt1 öt2e, öt2 are equal to each other. ^ EFFECT: high accuracy of determining moisture content. ^ 4 dwg, 1 tbl
