It pledges to lower greenhouse gas emissions by 2012. The guidelines of CDM put the focus on developing and emerging countries. Carbon emission reductions (CER) achieved in these countries can be traded to industrialised countries and used to balance the overall greenhouse gas emission. One way to achieve CERs is to convert methane into CO2 because methane is 21 times more critical as greenhouse gas than CO2. A prerequisite for being certified according to CDM is an extremely reliable and manipulation-free measurement of methane
The first biogas measuring station meeting the strict CDM demands
Carbosys CH4 CDE70 is a complete package with all necessary measuring devices. The combined methane measurement is compensated by temperature, pressure and humidity. The heart of the system is Memograph M. The data manager has been designed to meet the highest safety standards. It serves as reliable and manipulation-free calculator, event logger and counter for methane in normalized volume or mass.
The system is available as standardized solution with CDM-compliant documentation and enables our customers to optimize their project timing and achieve a fast ROI.
With Carbosys CH4 CDE70, Endress+Hauser is again living up to its reputation as a leader in developing and implementing customer and application-specific solutions.
Successful start in Sumatra, Indonesia
The first Carbosys measuring station has been commissioned successfully on a biogas plant at the Permata Hijau Group in Nubika, Indonesia. This biogas plant is part of a palm oil mill that generates substantial amounts of organic waste. The biological decomposition processes of this waste would release large amounts of biogas containing between 65 and 70 % of methane. To prevent this, the biogas plant includes further treatment. The biogas is trapped and forwarded to two collectors within the mill. About 80% is sent to a hydrogen production stage where hydrogen is created from the methane which is then reused for the palm oil refining processes.
20% go to a biogas flare that burns the excess biogas and thus converts it into less harmful substances such as CO2. Here, the reliable and manipulation-free methane measurement of Carbosys CH4 CDE70 is an integral part for the certification of the plant according to CDM criteria
Latest installation in Thailand
The latest 2 Carbosys CH4 CDE70 are just being shipped to Thailand. They will be installed in a palm oil mill in the upper southern region of Thailand. Traditionally, the COD (Chemical oxygen demand) levels of the palm oil mill effluent was reduced by letting it reside in open lagoons with anaerobic bacteria. This causes considerable methane emissions and a very bad smell of decay. Now, the palm oil mill utilizes a series of tank digesters where the generated biogas is used to produce electricity which is then fed into the Thailand grid. Methane emissions of the plant are considerably reduced and Carbosys CH4 CDE70 will provide the accurate methane measurement that enables the plant owner to trade the achieved carbon credits (CERs).
