5%Carbowax 20M Carbopack B填充柱 填充柱测定工业废气中甲醇的详细资料

填充柱测定工业废气中甲醇
填充柱测定工业废气中甲醇 详细信息：

名称：填充柱

色谱固定液：5%聚乙二醇
载体：石墨炭黑80-120目

规格：2m*3mm，2m*1/8

型号：5%Carbowax 20M Carbopack B

应用： HJ T33-1999 固定污染源排气中甲醇的测定气相色谱法

在甲醇合成、精馏工序中会释放出含甲醇的废气经废气输送管道进入U型吸附器，U型吸附器横管段内注入吸收液，两边直管段内填充活性炭作为吸附剂，经过三级净化处理后，剩余废气经光氧净化器进行强化净化，去除废气中的有害成分，使甲醇废气可被较彻底地吸收净化；除此之外，并联两个U型吸附器，当活性炭滤芯接近饱和时，可将待处理气体切换到另一个U型吸附器，净化处理的连续性，对于降低环境污染，促进安全生产，保障人员健康具有重要意义。


浩瀚色谱（山东）应用技术开发有限公司从顶空进样器载气压力、顶空瓶压力、顶空瓶温度等方面对自动顶空-气相色谱法测定水中甲醇的方法进行了优化。该方法的灵敏度高于直接进样(水溶液)法、已有的顶空进样法,满足《空气和废气监测分析方法》(第4版)中吸收液中甲醇检出限0.4 mg/L的要求。

Determination of Methanol in Industrial Waste Gas by Packed Column
Packed column determination of methanol in industrial waste gas Details:

Name: Packed Column

Chromatographic fixative: 5% polyethylene glycol
Carrier: graphite carbon black 80-120 mesh

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

Model: 5%Carbowax 20M Carbopack B

Application: HJ T33-1999 Determination of methanol in exhaust gas from stationary pollution sources by gas chromatography



In the methanol synthesis and rectification process, the waste gas containing methanol will be released into the U-shaped adsorber through the waste gas transportation pipeline. The absorbing liquid is injected into the horizontal pipe section of the U-shaped adsorber, and the straight pipe sections on both sides are filled with activated carbon as the adsorbent. After three-stage purification After treatment, the remaining exhaust gas is purified by the photo-oxygen purifier to remove harmful components in the exhaust gas, so that the methanol exhaust gas can be more thoroughly absorbed and purified; in addition, two U-shaped adsorbers are connected in parallel, when the activated carbon filter element is close to saturation At this time, the gas to be treated can be switched to another U-shaped adsorber to ensure the continuity of purification treatment, which is of great significance for reducing environmental pollution, promoting safe production and ensuring personnel health.


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. optimized the method of automatic headspace-gas chromatography for the determination of methanol in water from the aspects of headspace sampler carrier gas pressure, headspace bottle pressure, and headspace bottle temperature. The sensitivity of this method is higher than that of the direct injection (aqueous solution) method and the existing headspace injection method, and it satisfies the detection limit of 0.4 mg/L of methanol in the absorption liquid in "Air and Waste Gas Monitoring and Analysis Methods" (4th edition).
