Kit for the qualitative and quantitative chemical analysis of gas and methods of qualitative and quantitative chemical analysis of carbon dioxide and methane, ammonia (NH3) and hydrogen sulphide (H2S)

摘要

System and method for chemical analysis of qualitative and quantitative gas. The present invention, portable, applies to the chemical analysis of biogas, and similar gases, suitable for use in the field.The system and method involve colorimetric analysis of the concentration of the gas sulfidrico (H ~ 2 ~ s) and ammonia (NH ~ 3 ~), present in the biogas, and the analysis of carbon gas (Co ~ 2 ~) is the volumetric.The concentration of methane (CH ~ 4 ~) is estimated by subtracting the value obtained for carbon dioxide from the total volume collected.The key components of the present invention is a shipping box, a support bag sampler, gas analyzer 2, tap and hoses, four syringes, 20 ml for analysis.Two Co ~ 2 ~ A to H ~ 2 ~ s and a for NH ~ 3 ~ 4 buckets small glass, four large plastic buckets, 1000 ml of deionized water, the three reagents for NH ~ 3 ~ 15 ml each).Two reagents for H ~ 2 ~ s (20 ml and 10 ml) and two solutions for pre treatment (20 ml and 1000 ml). Low cost of manufacture and operation system, compact, may be easily transported.In addition, is an important tool to support agricultural production associated with plants producing biogas and biofertilizer by means of the digesters.However, it can be used broadly in systems that use or benefit from fuel gases compatible.
