Product Introduction

Coke oven gas, blast furnace gas, converter gas, artificial gas, water gas, and semi water gas are various gases closely related to people's production and life, widely used in household gas, petrochemicals, metallurgy, fine chemicals, and other fields. It is of great significance to calculate the calorific value of various gases by analyzing their composition and the content of each component.
The GC-1690T gas analysis dedicated chromatograph solves the full analysis of gases such as hydrogen, oxygen, nitrogen, carbon monoxide, carbon dioxide, and methane in gas with a single injection, and can directly calculate the calorific value. Adding optional attachments can also complete the determination of benzene, naphthalene, and hydrogen sulfide.

Main Features

This instrument is suitable for rapid analysis of water gas, semi water gas, coke oven gas, blast furnace gas, etc. The GC-1690 gas chromatograph is equipped with a single valve dual column and a thermal conductivity detector for gas analysis. The components include H2, O2, N2, CO, CO2, CH4. The detection range for H2 is 5% -100%, while for others it is 1ppm-100% (volume fraction). To detect H2S, simply add a flame photometric (FPD) detector and a dedicated column for H2S analysis, with dual channels in parallel. One injection can obtain the content of H2S, H2, O2, N2, CO, CO2, and CH4 components, with a detection range of 1ppm-100% for H2S. The system has an economical and reasonable configuration, simple operation and maintenance, high analysis efficiency, stable performance, and high repeatability. The analysis time can be controlled within 8 minutes or 5 minutes.

Technical Specifications

Configuration of dedicated gas chromatograph for coal gas:

1. GC1690T (high sensitivity TCD) 1 set

2. One set of heated six way sampler

3. Two stainless steel analysis columns

4. One set of chromatography workstation

5. One bottle of standard gas (including pressure reducing valve) (see table above)

6. One high-purity helium gas cylinder (recommended for on-site procurement)

7. One set of computer and printer (recommended to purchase on-site)

8. If trace amounts of H are to be detected in gas₂S requires optional components (1. FPD detector; 2.H₂1 dedicated analysis column for S; 3. One set of imported six way valve; )

Note: Replace 2 dedicated columns for gas analysis with 1 dedicated column for dimethyl ether, and replace the carrier gas with H2 (SGH-300A) to become a dedicated gas chromatograph for dimethyl ether
