What to do before for use biogas

What to do before  for use  biogas
    Improve the quality of gas (Gas Purification) prior to deployment have to be considered as George.
1. The trapped water in the gas pipeline.  Normally, gas production is often high humidity, approaching a new point.  When gas flows through the gas pipeline buried in soil at low temperatures often cause moisture (water vapor) in the gas condenses as water droplets and retained until it is a barrier to gas transmission pipeline to be.  So, to install a water trap before the gas is used.
2. reduce the amount of carbon dioxide (CO 2).
 Reduction in carbon dioxide (CO 2) from the gas will follow if and when needed, such as in the case of gas that the proportion of methane (CH 4) is very low and the level of igniting difficult.  CH 4 percentage is about 45 percent but less than in biogas production for the pig farm is not a problem in this regard.  Therefore, the reduction of carbon dioxide (CO 2) is not necessary.
3. reduction in hydrogen sulfide gas (H 2 S).  Reduction in gas hydrogen sulfide (H 2 S) contaminants in the biogas is qualified as a poisonous gas when exposed to water or steam is transformed to sulfuric acid, Rick (H 2 SO 4), which is the cause. acid rain or acid vapor can be corrosive to metals and materials.  Therefore, reducing hydrogen sulphide gas (H 2 S) in the first biogas utilization will be beneficial to the environment in general and will help extend the useful life of the equipment used with gas.
