Biogas can not be used immediately because it contains a large number of impurities and harmful substances. It must be purified before it can be put into normal use. Is the equipment in the process of better biogas purification and purification?

　　在yl6809永利的具体工艺设计中，首先要考虑项目的初期投资和后期的运营成本，根据沼气的流动范围和工艺要求来确定具体的设备、工艺。下面为大家介绍北京银河瑞环境下的三种工艺方法，供大家参考。

　　In the specific process design of biogas purification, the initial investment and later operation cost of the project shall be considered first, and the specific equipment and process shall be determined according to the flow range and process requirements of biogas. Here are three process methods under the environment of Beijing yinherui for your reference.

　　1. 变压吸附。

　　1. PSA.

　　该方法采用活性炭分子筛，能耗低，但甲烷损失较大。这种工艺方法需要预先脱硫。

　　This method uses activated carbon molecular sieve, which has low energy consumption but large methane loss. This process requires pre desulfurization.

　　2. 化学吸收。

　　2. Chemical absorption.

　　例如，胺法，甲烷的损失可以很低，高达0.1%。但它需要大量的热量和购买化学药品，以及预先脱硫。

　　For example, in the amine method, the loss of methane can be very low, up to 0.1%. But it requires a lot of heat and buying chemicals, as well as pre desulfurization.

　　3.高压清洗。

　　3. High pressure cleaning.

　　高压清洗也有一个甲烷损失的问题，好的制造商可以控制到1%甚至0.5%。

　　High pressure cleaning also has a problem of methane loss. Good manufacturers can control it to 1% or even 0.5%.

　　人们常常认为高压水清洗能耗高,事实上,yl6809永利,净化能源消耗主要发生在沼气增压阶段,和沼气的净化需要增压后,如果删除这部分能源消耗,高压水清洗能源消费不高。用于洗涤的水可以循环利用，实际用水量非常低。处理后的废气可用于蔬菜温室，为植物生长提供CO2。

　　People often think that the energy consumption of high-pressure water cleaning is high. In fact, the energy consumption of biogas purification and purification mainly occurs in the stage of biogas pressurization, and the purification of biogas needs pressurization. If this part of energy consumption is deleted, the energy consumption of high-pressure water cleaning is not high. The water used for washing can be recycled and the actual water consumption is very low. The treated waste gas can be used in vegetable greenhouse to provide CO2 for plant growth.
