Biogas upgrading and bio methane injection in biogas power plant

High biogas plant availability and accountability is generally required to obtain a bio-methane supply permit. To meet the regulations and requirements of the natural gas network system, an ultrasonic meter such as the 12-path ultrasonic flowmeter ALTOSONIC V12 is superior to classic mechanical counters.

It complies with several international and local standards such as MID MI-002, OIML R137, AGA-9 etc., is maintenance-free and measures volume without a flow straightener and without losing pressure. If the calorific value of the gas needs to be adjusted by adding liquid gas, the OPTIMASS 6400 mass flowmeter is the right measuring instrument. The SUMMIT 8800 flow computer calculates the standard volume based on the input variables of gas pressure, temperature, calorific value and operating volume. It is flexible in configuration and compliant with all main international standards such as OIML, ISO, API, AGA, GOST. With a gas chromatograph and a flow computer, the system will produce the reports and billing accuracy required. KROHNE supplies complete systems and skids tested and ready for operation containing all instruments, valves, heat exchangers and controls. The DK800 variable area flowmeter measures sample flow, the very low volume of gas supplied to the gas chromatograph to measure the gas quality - to determine the calorific value and then feed this into the flow computer alongside the flow measurement from the ALTOSONIC flowmeter.
