沼气如何净化提纯

首页- 新闻资讯 > 行业资讯 > 2022-06-02

沼气的主要成分是CH4和CO2,此外,还含有微量的H2O、水等杂质。利用沼气生产管道燃气、GNG和LNG,其技术难点在于沼气的净化提纯。因此需要通过必要的沼气净化提纯技术,使沼气成为甲烷含量高,热值和杂质等条件符合管道、压缩或液化天然气标准要求的高品质生物天然气。

Methane is mainly composed of CH4 and CO2. In addition, it also contains a small amount of H2O, water and other impurities. The technical difficulty of using biogas to produce pipeline gas, GNG and LNG lies in the purification of biogas. Therefore, it is necessary to adopt necessary biogas purification and purification technology to make biogas become high-quality biological natural gas with high methane content and conditions such as calorific value and impurities that meet the requirements of pipeline, compressed or liquefied natural gas standards.
沼气净化一般是去除沼气中微量的有害组分,以提高燃气的适用性和热值,经过净化提纯得到的生物天然气可以作为替代天然气使用。净化提纯工艺有几方面,沼气脱硫,沼气脱氧,沼气干燥,沼气脱碳,其他杂质的脱除。1、脱硫工艺,发酵过程产生的气体经过干燥柜重力除水和高能离子除臭设备除水、除臭后进入双膜储气囊暂存。由于沼气原气中含有一定量的H2S气体,需经过脱硫工序将H2S气体脱除净化。气体从干法脱硫塔的底部进入,顶部排出,气体在干法脱硫塔内与干法脱硫剂接触,使得H2S被脱除。2、沼气脱碳,脱硫后的沼气经过气柜稳压后,经过滤器去除饱和水蒸气和微尘粒后,进入膜分离装置,使得CH4、CO2混合气体彼此分离,分离后终沼气中CO2浓度在3%以下,分离出的CO2几乎不含CH4。
Biogas purification is generally to remove trace harmful components in biogas to improve the applicability and calorific value of gas. The purified biogas can be used as a substitute for natural gas. There are several aspects of purification process, including biogas desulfurization, biogas deoxidation, biogas drying, biogas decarbonization and removal of other impurities. 1. In the desulfurization process, the gas generated in the fermentation process enters the double membrane air bag for temporary storage after being dewatered by gravity in the drying cabinet and dewatered and deodorized by the high-energy ion deodorization equipment. Since biogas raw gas contains a certain amount of H2S gas, H2S gas needs to be removed and purified through desulfurization process. The gas enters from the bottom of the dry desulfurization tower and is discharged from the top. The gas contacts with the dry desulfurizer in the dry desulfurization tower to remove H2S. 2. Biogas decarbonization: after the desulfurization biogas is stabilized in the gas holder, the saturated steam and micro dust particles are removed through the filter, and then enter the membrane separation device to separate the CH4 and CO2 mixed gas from each other. After separation, the CO2 concentration in the final biogas is less than 3%, and the separated CO2 contains almost no CH4.
沼气净化提纯生产生物甲烷,品质相当于化石天然气,在条件允许下,可直接并入管道燃气,也可制成压缩天然气,用于汽车燃料等。沼气净化提纯技术工艺较多,开封迪尔空分可根据用户自身资金成本和能源化利用目标进行设计选择。
Biogas purification and purification produces biomethane, which is equivalent to fossil natural gas in quality. If conditions permit, it can be directly incorporated into pipeline gas, or it can be made into compressed natural gas for automotive fuel, etc. There are many biogas purification technologies. Kaifeng Deere air separation can be designed and selected according to the user's own capital cost and energy utilization goal.
