二氧化碳产品的原料主要来源于乙烯氧化副产气、合成氨及发酵尾气、地下气井等,硫化物在其中普遍存在且形态不一.合成氨法二氧化碳原料气中的硫化物主要为硫化氢、氧硫化碳、二氧化硫等;地下气井二氧化碳原料气中的硫化物主要为硫化氢等还原态硫化物;发酵法二氧化碳原料气中的硫化物主要为硫醇、硫醚等有机硫化物.由于硫化物的存在会严重影响饮料的品质,还会对人体健康产生危害,因此目前国家标准及国际饮料协会标准中对硫化物的控制很严格,总硫要求≤0.1ppm,二氧化硫≤1ppm.

目前二氧化碳中硫化物的测定方法有氧化微库仑法、紫外荧光法、硫化氢色带法、分光光度法、气相色谱法等。火焰光度分析硫化物的原理:样品在富氢火焰燃烧时，含硫化合物发射出波长为394nm的特征光。通过滤光片将特征光过滤后，再经光电倍增管将光信号转换成电信号，微电流放大后纪录。综上可知，硫化物的火焰光度分析方法是一种切实可行的硫检测方法。

Specification: 60mm*3mm

Maximum operating temperature: 100°C

Application: Removal of sulfur dioxide in food grade/liquid carbon dioxide

The raw materials of carbon dioxide products mainly come from ethylene oxidation by-product gas, synthetic ammonia and fermentation tail gas, underground gas wells, etc., sulfides are ubiquitous in them and have different forms. The sulfides in the carbon dioxide feed gas of the synthetic ammonia process are mainly hydrogen sulfide and carbon oxysulfide , Sulfur dioxide, etc.; the sulfides in the carbon dioxide feed gas of underground gas wells are mainly reduced sulfides such as hydrogen sulfide; the sulfides in the carbon dioxide feed gas of the fermentation method are mainly organic sulfides such as mercaptans and sulfides. Due to the presence of sulfides It seriously affects the quality of beverages and also harms human health.Therefore, the current national standards and the International Beverage Association standards have strict control of sulfides, with total sulfur requirements ≤0.1ppm and sulfur dioxide ≤1ppm.

At present, the determination methods of sulfide in carbon dioxide include oxidation microcoulometric method, ultraviolet fluorescence method, hydrogen sulfide ribbon method, spectrophotometry, gas chromatography and so on. The principle of flame photometric analysis of sulfide: When the sample is burned in a hydrogen-rich flame, the sulfur-containing compound emits characteristic light with a wavelength of 394nm. After the characteristic light is filtered by a filter, the light signal is converted into an electrical signal by a photomultiplier tube, and the micro current is amplified and recorded. In summary, the flame photometric analysis method of sulfide is a practical method for sulfur detection.

The desulfurization tube developed by Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. can not only detect the content of total sulfur, but also determine the type of sulfide, which is very suitable for quality control and factory inspection of carbon dioxide plants.
