the cheapest desulfurization tower for biogas generator

The introduction of desulfurization tower: Biogas Desulfurizer is designed to clean biogas by removing sulphur, dust and water from biogas, stablize biogas pressure so that stable and clean biogas can be used on biogas engine.   The main composition of desulphurizer is ferric oxide (Fe2O3)       After some time of use, Fe2O3 will lose its effectiveness ( you can find that there is bad smell when using biogas). In this case, you must replace the Fe2O3 in time.       There are different sizes of desulphurizer:   1) Family size desulphurizer   Net weight: 1L/4L/8L   Can treat 200m3 biogas totally, suitable to treat not more than 5m3 of biogas per day, for small size biogas system.
