Domestic universities and seminars have also stopped the experiment of biogas production by fermentation. Portable biogas analyzer is needed to stop monitoring the biogas generated every day in the experimental process. The following is what the biogas desulfurization company did for us:
Gasboard-3200L biogas analyzer can measure the volume concentration of CH4, CO2, O2 and H2S at the same time. In the process of field test, the experience of field operation and the condition of repairing the instrument are separated. The following questions need attention:
1 Instrument water intake. Biogas contains a lot of water. If it has not been dewatered or the dewatering effect is not good, it will bring liquid water into the instrument, causing sensor pollution, and the instrument can not be used normally. 2 Laboratory fermentation biogas production is very small, only 300-500 ml a day, but the need to stop monitoring every day, lack of sample gas, resulting in inaccurate and unstable instrumental test values. 3. The experimenters are very confident about the consumption of biogas and have doubts about the test sample gas data, but there is no standard gas to stop textual research on the spot.
In response to the above common problems, the treatment plan is as follows:
1. Biogas analyzer is equipped with pre-disposal equipment. In view of the site with more moisture, it is proposed to participate in a dewatering filter after pre-disposal, which can effectively remove moisture and pollutants in biogas and ensure that the sensor of the instrument does not water. 2. On-site methane production is less, which leads to inaccurate test values. It can be communicated with customers. After the methane has passed through the water, it can be collected and directly extracted into the methane analyzer for testing. The flow range is 0.7-1.2L/MIN, and the data can be read after 20 seconds extraction. In the sales process, it is better to recommend that customers configure standard gases, especially CH4 standard gases. When customers have doubts about testing sample gases, they can test standard gases to verify whether it is an instrument problem or a biogas consumption process problem.
With the country's attention to biogas energy, the discussion on biogas in universities and scientific research departments, and the emergence of large and medium-sized biogas projects, biogas analyzer will have a larger market and better development prospects.
