Biogas contains elements that are not needed in the combustion, especially water ( H2O) and hydrogen sulfide ( H2S) . In circumstances where the biogas is used as burning material ( stove) elements affect only the second decline in the flame of the stove. However, unlike if the biogas is used as fuel for generating electricity or running a generator, washing or purification of biogas to be very important because the two elements will affect the life of engine components plant.

Purification purposes ( biogas purification) for condensate formed can accumulate in the gas line and also can form a corrosive acid solution when in contact with water. In addition to corrosion prevention, biogas purification also avoid the toxicity of H2S ( the maximum threshold of 5 ppm, to prevent sulfur content when burned to SO2 or SO3 with poison stronger than H2S as well as minimizing the formation of highly corrosive H2SO3.

Purifying methane ( Biogas methane purifier) MP 1270 is made   of a metal tube diameter of 12 cm, height 70 cm, containing the tablets absorber H2S and H2O as much as 5 kilograms, capable of purifying the biogas flow of 4 m3 / day, withstand pressure up to 10.5 bar, have a better economic future of 5 ( five) years.

Absorbent tablet made from a mixture of minerals with a strong base NaOH, which can be replaced ( refill) per 2 ( two) months of usage or regenerated for usage up to 1 year. The tool is designed for methane purifier capable of raising the benefits and quality of biogas, the generation of a reactor or vessel digestion ( digester) with an output of 3 to 4 m3 of gas per day, raising the composition of methane in biogas to 20% , while lowering the content of CO2, H2O and H2S. Tablet absorbent ( absorbent) to refill ( refill) at a low cost per 2 months or so, regenerated ( re-use) by immersion in aquades to a maximum of 5x or the equivalent of 1 ( one) year.
