沼气想要得到广泛的应用,少不了沼气提纯这一步骤,沼气经过提纯,可以极大程度上减少沼气中水、碳化物和硫化物的成分,这也构成了沼气提纯设备的三大系统,下面就给大家详细介绍一下,希望对大家有所帮助!
If biogas wants to be widely used, it needs the step of biogas purification. After biogas purification, it can greatly reduce the composition of water, carbides and sulfides in biogas. This also constitutes the three major systems of biogas purification equipment. Here we will give you a detailed introduction, hoping to be helpful to you all! 
1.脱水、脱硫系统
1. Dehydration and desulfurization systems
水汽的去除主要在冷凝器中进行,从厌氧反应器出来含有饱和水汽的沼气在经过冷凝器时,其中所含水汽冷却凝结,达到干燥的目的。
The removal of water vapor is mainly carried out in the condenser. The methane with saturated water vapor coming out of the anaerobic reactor is cooled and condensed in the condenser to achieve the purpose of drying.
H2S通过箱式脱硫设备去除,采用干法脱硫连续再生工艺。干法脱硫是在脱硫设备内装填一定高度的脱硫剂,沼气自下而上通过脱硫剂,H2S被去除,实现脱硫过程,其中脱硫剂以氧化铁为主要活性催化组分,并添加多种助催化剂与载体,在常温常压下通过催化作用去除H2S,脱硫率可达90%以上。处理净化后沼气中的H2S含量须低于200ppm。
H2S is removed by box desulfurization equipment, and the continuous regeneration process of dry desulfurization is adopted. Dry desulfurization is a process of desulfurization by filling a certain height of desulfurizer in the desulfurization equipment. Biogas is removed from bottom to top through desulfurizer, and H2S is removed. Among them, the desulfurizer takes iron oxide as the main active catalytic component, and adds a variety of promoters and carriers. The desulfurization rate can reach more than 90% by catalytic action at room temperature and pressure. After treatment and purification, the H2S content in biogas should be less than 200 ppm.
2.脱碳系统
2. Decarbonization system
沼气提纯设备
变压吸附,是一个近似等温变化的物理过程,它是利用气体介质中不同组分在吸附剂上的吸附容量的不同,吸附剂在压力升高时进行选择性吸附,在压力降低时得到脱附再生。
Pressure swing adsorption (PSA) is an approximate isothermal process. It utilizes the different adsorption capacity of different components on adsorbents in gas medium. The adsorbents are selectively adsorbed when the pressure rises and regenerated when the pressure decreases.
沼气首先通过过滤器以去除气体中的颗粒物质;再被压缩进入无油压缩机,压力达到大约2~4bar;再经过一个用水冷却的冷却机以去除沼气压缩过程中产生的热;后压缩后的沼气被输送到吸附床,在那里CH4与CO、H2S以及沼气中的其他成分分开。
Biogas is first filtered to remove particulate matter from the gas; then compressed into an oil-free compressor with a pressure of about 2-4 bars; then cooled by a water cooler to remove heat generated during the compression of biogas; and finally compressed biogas is transported to the adsorption bed, where CH4 is separated from CO, H2S and other components of biogas.
当吸附床饱和时,而且产气不能够再满足低的天然气纯度时,吸附床须进行再生。吸附床的再生须要将床的压力从运行压力(2~4barg)降到大气压。利用一个通过微处理器控制的阀门管路来实现吸附床的在线和离线转换。
When the adsorbent bed is saturated and the gas production can no longer meet the minimum natural gas purity, the adsorbent bed must be regenerated. The regeneration of the adsorbent bed must reduce the pressure of the bed from the operating pressure (2-4 barg) to the atmospheric pressure. An on-line and off-line conversion of the adsorption bed is realized by a valve pipeline controlled by a microprocessor.
沼气经过脱水、脱硫和脱碳系统处理,沼气的CH4含量达到90%以上,达到可以作为天然气利用的纯度后,通过沼气罐缓冲,由高压天然气运输车运送场外销售。
After dehydration, desulfurization and decarbonization, the methane content of CH4 reaches more than 90%, which can be used as the purity of natural gas. After being buffered by the methane tank, the methane is transported by the high-pressure natural gas transporter for off-site sale.
