Rapid measurement apparatus for total amount of moisture and evaporation loss of petroleum heavy oil components, and method thereof

Abstract

The invention relates to a rapid measurement apparatus for the total amount of moisture and evaporation loss of petroleum heavy oil components, and a method thereof. According to the apparatus, an evaporation container is arranged on an electric heating furnace; the upper part of a thermometer and a stirring device transimisson head are connected with a column; the lower part of the thermometer and the stirring rod are placed in the evaporation container. According to the method, the weight of a sample before the evaporation is measured, and the measurement apparatus is assembled; the electric heating furnace is opened to heat the evaporation container to a temperature of 150 DEG C; the heating treatment is continuously performed until the thermometer shows the temperature of 175-185 DEG C, a stirring treatment is performed for the sample for 30-60 minutes at the temperature, then the weight of the sample after the evaporation is measured; the total amount of the moisture and the evaporation loss of the petroleum heavy oil components is the difference / the weight of the sample before the evaporation, wherein the difference is the difference of the weight of the sample before the evaporation and the weight of the sample after the evaporation. According to the present invention, the apparatus of the present invention has characteristics of convenient operation, low cost and reliable measurement result, and the reliable measurement result meets the requirements of the measurement result of the total amount of the moisture and the evaporation loss of the petroleum heavy oil components; specialized equipment and professional technicians are not required; the operation is convenient and practical; the time is saved; the labor efficiency is improved.

Description

technical field [0001] The invention relates to a measuring device and method for the total amount of water content and evaporation loss of petroleum heavy oil. This method is suitable for modified asphalt waterproofing membrane production enterprises before production, or other situations that need to measure the total amount of water and light oil in petroleum heavy oil such as petroleum asphalt, residual oil, oil slurry, and lubricating oil as soon as possible Adopted below. Background technique [0002] At present, according to the method of detecting the moisture and evaporation loss of petroleum asphalt or other petroleum heavy oil, it is necessary to measure the moisture and evaporation loss of the heavy oil respectively, and the time required to complete the two determinations of moisture and evaporation loss in a petroleum heavy oil is Both are relatively long. [0003] For example, asphalt, to measure the moisture of petroleum asphalt, extract the moisture with a...
