Vaisala CARBOCAPâ MGP262 Multigas Probe for Methane and Carbon Dioxide Measurement is designed for demanding in situ measurement of the offgas in the biogas upgrading process, where low concentrations of methane need to be measured reliably and with high accuracy in the presence of high concentrations of carbon dioxide. The probe belongs to the Vaisala MGP260 series product family.

Direct view to process

performance

MGP262 measures the concentrations of the main components in the offgas stream of a biogas upgrading process: methane and carbon dioxide. The methane concentration in the offgas is one of the direct indicators of the process performance. The lower the offgas methane concentration, the lower the methane loss, hence higher yield from the biogas and the smaller the environmental impact. Monitoring offgas composition reliably and accurately enables optimizing the upgrading process as well as determining the amount of greenhouse gases emitted from the process for environmental compliance purposes.

Outstanding methane measurement performance

MGP262 has been optimized for measuring methane concentrations below 5 vol-% with an accuracy of ±0.15 vol-%. Combined with a wide temperature range (-40 to +60 °C), MGP262 is ideal for a wide range of upgrading technologies and processes.

Ease of use

MGP262 is unique in being an in situ probe for demanding explosive environments. No sampling system is needed and there are no moving parts in the probe. Apart from an annual calibration check, MGP262 does not need any consumables or calibration gas cylinders, which makes its maintenance very easy.

Robust, weatherproof, and Ex-certified for Zones 0 and 1

MGP262 is internationally certified for Zone 0 inside the pipeline and Zone 1 on the outside, allowing installation in any Ex hazardous environment expected in the biogas and natural gas industry. The probe is IP66-rated and specified for ambient temperatures from -40 to +60°C for outdoor installation in harsh environments. Stainless-steel construction, hermetic sealing of optics, and encapsulated electronics provide the probe with maximum robustness and resilience to mechanical shocks, vibration, and corrosive chemicals.

PRISM Membrane Options for Biogas Upgrading

In the process of upgrading biogas to high purity biomethane, balancing the relationship among purification efficiency, operational energy consumption, and investment costs has always been a challenge for the industry. PRISM^® Biogas Upgrading Membrane Separators break this "impossible trinity" through exceptional modular design and highly flexible customization capabilities. By precisely selecting different membrane separators based on specific project scales, raw gas compositions, and target product gas standards, PRISM^® enables a diverse range of solutions from "single-focus excellence" to "comprehensive balance."

1. High Methane Recovery Configuration

This combination maximizes the removal of impurities like carbon dioxide and hydrogen sulfide, ensuring the methane concentration in the product methane purity up to 99.8%, while minimizing methane loss and achieving maximum resource utilization.

2. Low Power Configuration

For projects sensitive to operating costs or with limited power resources, the low-power advantage of PRISM^® membranes becomes prominent. By optimizing the arrangement and combination of membrane modules and inlet biogas flow rate, the load on compressors and refrigeration equipment is significantly reduced.

3. Low Capital Configuration

For budget-conscious projects with sensitive payback periods, the PRISM^® membrane system offers highly cost-effective standardized or simplified 2-stage purification configurations. While ensuring basic purification effects, this approach streamlines post-treatment steps, significantly reducing initial equipment investment.
