Abstract

The invention relates to a measurement method for oil-water ash content in gas, and the method comprises the following steps: after the gas is cooled and processed for several times, collecting a mixture of condensed oil content, moisture and ash content, and measuring the quality of the mixture; then, transferring the mixture to a conical flask, and measuring the quality of the mixture; connecting the conical flask with a moisture measurement device; measuring the quality of the moisture in the mixture; according to the quality, calculating the water content in the gas; continuously heating residue of which the moisture is measured until no liquid exists in the conical flask; then, transferring the conical flask to a muffle furnace to heat, taking out the conical flask, cooling, and measuring the content of ash in the gas; subtracting the water content and the ash content from the total mass; and calculating to obtain the oil content in the gas. By utilizing the method, the oil content, the water content and the ash content in the gas can be precisely measured once, and the method is good in repeatability; and an oil sample, a water sample and an ash sample in the collected gas can be further analyzed and tested.

Description

technical field [0001] The invention relates to a method for measuring the content of oil, water and ash in gas, belonging to the technical field of gas detection. Background technique [0002] The content of oil, water and ash in gas is an important index to evaluate the quality of gas products, and whether the measured values ​​of oil, water and ash in gas generated in industrial processing are accurate is crucial to the calculation of material balance and heat balance of industrial devices. Calculation, device improvement, gas upgrading and processing, and gas recycling have important guiding significance. The composition of gas is relatively complex, and the concentrations of oil, water and ash in local gas are not the same. At present, there are reports on methods for measuring oil content, water content and dust in gas, but there is no method that can accurately and Directly and simultaneously determine the oil, water and ash content in the gas. [0003] The oil cont...
