Coarse content detector in coke oven gas

The gas chromatograph produced by our company has the advantages of high efficiency, high selectivity, high sensitivity, fast analysis speed, small sample consumption, and high quantitative accuracy for crude content in coke oven gas. This method has been widely used in various impurity content in coking plants. analysis. The main components of the crude oil are, , , 2 and 3. In addition, it also contains a small amount of impurities such as phenols, pyridine bases, sulfides and some unsaturated compounds, the highest content of which is about % to %. The system is toxic, especially the low boiling point substances are more toxic. The analysis of systems is of great significance in coking production. The coking industry has always used the activated carbon adsorption method to analyze the system. This method takes a long time to measure, is highly toxic, and cannot obtain quantitative results of the system, which cannot meet the requirements of modern production. Analysis principle: This method uses a hydrogen flame ion detector chromatograph with Apison as the stationary liquid carrier. The gas is collected with a gas sampling bag and injected into the instrument through a six-way valve. After being separated by the chromatographic column, the components enter the hydrogen flame ion detector one by one. The chromatograms obtained on the chromatography workstation were quantitatively calibrated according to the single-point external standard method.
