An Online Fully-Automatic High Precision Monitoring System of Steam Dryness Based on Spectral Absorption Characteristics

Abstract

Steam dryness detection is crucial in the field of oil exploitation. A steam dryness too high will be dangerous, whereas a low steam dryness too low will affect the efficiency of extraction. Therefore, real-time, high-precision detection of steam dryness is essential. The methods for detecting steam dryness include chemical, thermodynamic, radiometric, and microwave. The manual test method possesses the best detection accuracy. However, the real-time performance is not good, and the detection process is cumbersome. This article uses a silver nitrate solution to titrate chloride ions and combine them with the change in the absorbance of the solution to determine the endpoint of the titration. This article reported that the automatic chloride ion concentration measurement was a rep and that the detection of chloride ion concentration was 15 mg l−1. The detection linearity reached 0.992. Therefore, our titration endpoint judgment method has better anti-interference.
