本標(biāo)準(zhǔn)規(guī)定了煤基費(fèi)托合成原料氣中H2、N2、CO、CO2 和CH4 的氣相色譜測定方法。 
本標(biāo)準(zhǔn)適用于表1所示范圍的煤基費(fèi)托合成原料氣中H2、N2、CO、CO2 和CH4 組分含量的測定。

煤制油裝置的過程控制——費(fèi)托合成的原料氣即合成氣中的有效成分是一項重要調(diào)控指標(biāo),氣相色譜法是檢測合成氣組分的快速有效方法.日常分析中,由于合成氣試樣含有水分等雜質(zhì),嚴(yán)重影響色譜進(jìn)樣系統(tǒng)的完好性及分子篩色譜柱的分離柱效,載氣中的痕量水和CO2也會導(dǎo)致分子篩色譜柱快速失效.為此,浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司通過試驗探索日常分析中遇到的試樣含水等雜質(zhì),分子篩柱柱效下降快這兩項突出問題的解決辦法——采取了靜置取樣氣袋,增設(shè)過濾篩板,增加閥切事件的改進(jìn)措施,確定了閥切事件的時間參數(shù).試驗結(jié)果表明,優(yōu)化改進(jìn)后的氣相色譜法精密度和準(zhǔn)確度均較高,不僅可快速,準(zhǔn)確測定粗合成氣及變換氣中的有效氣成分,而且可有效解決樣品含雜質(zhì)及分子篩柱使用壽命短的問題,并可節(jié)約色譜儀耗材的支出費(fèi)用.

Coal-based Fischer-Tropsch synthesis gas composition detection TDX-01 packed column Details:

Name: Packed Column

Stationary Phase: Carbon Molecular Sieve

Specifications: 2m*3mm, 2m*1/8

Model: TDX-01

Granularity: 80-100 mesh

Application: GBT 27884-2011 Determination of H2, N2, CO, CO2 and CH4 in coal-based Fischer-Tropsch synthesis feed gas-Gas chromatography
This standard specifies the gas chromatographic method for determination of H2, N2, CO, CO2 and CH4 in coal-based Fischer-Tropsch synthesis feed gas.
This standard applies to the determination of the content of H2, N2, CO, CO2 and CH4 components in the coal-based Fischer-Tropsch synthesis feed gas within the range shown in Table 1.

Process control of coal-to-liquids plant—the active ingredient in the feed gas of Fischer-Tropsch synthesis, that is, the syngas, is an important control index, and gas chromatography is a fast and effective method for detecting syngas components. In daily analysis, due to syngas The sample contains impurities such as moisture, which seriously affect the integrity of the chromatographic sampling system and the separation efficiency of the molecular sieve column. Trace water and CO2 in the carrier gas will also cause the molecular sieve column to fail rapidly. Therefore, Haohan Chromatography (Shandong) ) Application Technology Development Co., Ltd. through experiments to explore the solutions to the two prominent problems encountered in daily analysis, such as water in the sample and the rapid decline of molecular sieve column efficiency. The improvement measures for the valve cut event were added, and the optimal time parameters for the valve cut event were determined. The test results show that the optimized and improved gas chromatography method has high precision and accuracy, and it can not only quickly and accurately measure the crude syngas and transformed gas It can effectively solve the problem of impurities in the sample and the short service life of the molecular sieve column, and can save the expenditure of chromatograph consumables.
