Determination of hydrogen sulfide in coke oven gas by gas chromatography

Details of determination of hydrogen sulfide in coke oven gas by gas chromatography:



Name: capillary column

Specification: 30m * 0.32

Model: HH-GASPRO

Name: capillary column

Specification: 30m * 0.32 * 0.25

Model: HH-FFAP

Application: coke oven gas -- Determination of hydrogen sulfide content -- Gas chromatography



The determination of hydrogen sulfide content in coke oven gas is an important content of coking inspection and test. At present, many coking enterprises use gas chromatography to determine the hydrogen sulfide content, which has achieved ideal detection results This method has the characteristics of simple operation, high inspection efficiency and little interference from other substances. It can quickly and accurately determine the hydrogen sulfide content data of coke oven gas, thus providing scientific reference and guidance for safe and clean production of coking enterprises



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has systematically studied the determination of hydrogen sulfide content in coal gas by gas chromatography. The highly inert polyfluoroethylene (PVF) gas sampling bag is used to replace the wet gas flowmeter and absorption bottle, simplifying the sampling operation. A 30 m low sulfur capillary chromatographic column and FPD detector were used to separate and analyze H in coke oven gas_ 2S、COS、CS_ 2. There are four main sulfides of thiophene. The instrument sensitivity is improved by using the optimized VI sampling port and special sulfur passivation pipeline, and the detection limit of the method can reach 1mg/Nm~3. The multi-point correction and quadratic curve fitting are adopted, and the measurement range is from 10 mg/Nm~3 to 300 mg/Nm~3. The method is compared with the iodimetric method for the determination of hydrogen sulfide in coal gas. The precision test and accuracy verification prove that the method is simple, fast, accurate and reliable, and meets the requirements of trace analysis.
