Mercury monitoring system for natural gas MMS-NG
Mercury monitoring system for natural gas MMS-NG
- Detects both elemental and bound mercury with automatic calibration.
- Equipped with a sample point multiplexer supporting 2 to 16 channels.
- Operates without the need for carrier gases and is certified for hazardous zones.
- Multiplexer Module: Supports 2 to 16 sampling points with continuous purging of sample lines at 40-80 l/h per channel. Measuring duration is approximately 3 minutes, adjustable per channel.
- Detector: Utilizes UV absorption (CVAAS) at a wavelength of 253.7 nm. Features amalgamation on a gold surface with thermal desorption (MI GoldTrap). Measuring range is 0.001 - 50 μg/m3, extendable to 2000 μg/m3 with sample dilution.
- Signal Outputs: Includes analog (4-20 mA), serial (RS 232), Modbus RTU RS485 (optional), and Ethernet (optional).
- Sample Conditioning System (SCS): Maximum inlet pressure is 240 bar, with a heated pressure regulator. Output pressure ranges from 0.07 to 2 bar. Sample surfaces are coated to minimize mercury adsorption.
- Automatic Calibrator: Operates on mercury vapor saturation with constant volume injection, using NIST recommended equations for mercury vapor pressure calculation.
- Hazardous zone certification: ATEX 2G IIC T4 EExp or equivalent.
- Calibration standards: ISO/DIS 6978-3, ASTM D 5954, VDI 2267 Part 8, NIST recommendations.
- Sampling and mercury determination: ISO 6978-1, ASTM 5954.
- Quality and safety certifications: OHSAS 18001:2007, ISO 14001:2015, ISO 9001:2015.
