Dilution&Sampling Systems for Portable Hydrocarbon Spectrometers

Product catalog summary

Project Overview
The project, in collaboration with the Politecnico di Bari, focuses on developing Dilution & Sampling Systems for Portable Hydrocarbon Spectrometers. The PolySenSe Lab, led by Vincenzo Spagnolo, is spearheading this initiative. Vincenzo Spagnolo, a Full Professor of Applied Physics at the Technical University of Bari, has extensive experience in gas sensing techniques.

Role of MCQ Instruments
MCQ Instruments is responsible for diluting gas samples and generating a controlled flow to be fed directly to the mass spectrometer.

Project Specifications

Gas Dilution: The system allows for precise gas dilution, crucial for accurate spectrometer readings.
Controlled Flow: The GB100 Series enables control of gas flow from 0.1 ml/min to 500 ml/min without cut-off.
Software Automation: The Software PRO version facilitates automated experiments, enhancing efficiency.

Benefits and Savings

Time Savings: The Gas Mixer allows setting calibration points quickly, eliminating the need for multiple calibration cylinders.
Compact Design: The Gas Mixer is more compact than traditional flow controllers and can be specifically calibrated for the intended gas mixture.

Technical Insights
Laser-based optical techniques are employed for real-time and in-situ analysis of natural gas composition, crucial for the oil & gas industry. These techniques offer high sensitivity, detecting trace gases at parts-per-quadrillion levels in controlled environments. However, extending detection to the percent scale remains challenging due to high methane concentrations in natural gas samples.

Challenges and Solutions

Dynamic Range Extension: The challenge lies in extending the detection range to accommodate high methane concentrations.
Dilution Strategy: Diluting natural gas with pure nitrogen in varying ratios addresses issues of absorption non-linearity and sensor saturation.

Conclusion
The integration of dilution/sampling systems within sensors holds potential for advancing in-situ gas analyzers, making laser-based techniques a promising solution for hydrocarbon identification in real-world applications.

Dilution&Sampling Systems for Portable Hydrocarbon Spectrometers-2

DESCRIPTION OF THE APPLICATION AND THE TARGET The real time and in-situ analysis of natural gas composition is a powerful tool in oil&gas industry for estimating reserves, rock characterization and assisted drilling. Laser based optical techniques represent suitable solutions for addressing this tasks, since they exploit the laser’s narrow spectral resolution and allow for unambiguous detection of trace gas for each component in downhole samples. To date it has been demonstrated that trace gas species can be optically detected with sensitivities down to parts - per -quadrillion concentration...
