(EN) METHOD FOR MEASURING CONCENTRATION OF GASEOUS SPECIES IN BIOGAS
(ZH) 用于测量沼气中的气态物质浓度的方法
Abrégé
(EN) The invention relates to a method for in situ measurement of the concentration of gaseous chemical species contained in a biogas (10) circulating in a line (20), for example of a biogas treatment plant or of a system utilizing a biogas. The method of the invention is implemented by means of an optical measurement system (40) comprising a light source (41) and a spectrometer (44). The source (41) emits UV radiation (42) through the biogas (10) within a measurement area (21) situated in the line. The spectrometer (44) detects at least a portion of said UV radiation having passed through the biogas (10) and generates a digital signal of the luminous intensity (50) depending on the wavelength of the portion of the UV radiation having passed through the biogas. A determination is then made of the concentration of the chemical species from the digital signal of the luminous intensity (50).
(ZH) 本发明涉及一种用于对例如在沼气处理厂或使用沼气的系统中的管道(20)中流动的沼气(10)中所含的气态化学物质的浓度进行原位测量的方法。根据本发明的方法借助于光学测量系统(40)来实现,该光学测量系统(40)包括光源(41)和光谱仪(44)。光源(41)发射穿过管道中的测量区(21)内的沼气(10)的UV辐射(42)。光谱仪(44)检测已穿过沼气(10)的所述UV辐射的至少一部分,并且其生成因变于已穿过沼气的UV辐射部分的波长的光强度的数字信号(50)。然后根据数字光强度信号(50)确定化学物质浓度。
