Overview
The 2100 BOG Cryogenic Gas Sampling System consists of PROBE 2100 BOG Probe and SAMP 2100 Sampling Cabinet, an industrial-grade sampling system designed specifically for cryogenic environments and extreme conditions. PROBE 2100 probe is responsible for sample gas collection, vibration resistance, vaporization, and liquid removal, while SAMP 2100 cabinet handles sealed sample collection, pretreatment, and safe sampling. The system complies with ISO 8943:2025 standard requirements and is suitable for LNG receiving terminals, cryogenic gasification stations, offshore energy facilities (FSRU/FLNG), and other critical scenarios, ensuring sample collection accuracy and operational safety.
Key Specifications
Core Components
The system consists of two core components working together to provide a complete BOG sampling solution.
PROBE 2100 BOG Probe
PROBE 2100 is an industrial-grade sampling interface designed for cryogenic environments and extreme conditions, adopting a heavy-duty reinforced design with extremely high mechanical strength, effectively suppressing vortex-induced vibration (VIV) generated by high-flow pipelines. Built-in multi-stage expansion chamber design utilizes the principle of sudden velocity drop to achieve gravity settling of sample gas, effectively intercepting and returning tiny liquid droplets entrained in the medium, ensuring that the sample gas entering the subsequent analysis system is completely dry and pure gaseous. Ultra-large heat dissipation surface design maintains smooth air convection even under severe frosting conditions, ensuring sample gas temperature always remains above the dew point. As a passive device, it relies on natural convection for heat exchange, with no electronic components or moving parts internally, conforming to Intrinsically Safe design logic.
SAMP 2100 Sampling Cabinet
SAMP 2100 Sampling Cabinet is made of 316 Stainless Steel (316SS) with double-layer insulation structure (40mm insulation thickness), meeting corrosion resistance and low-temperature operating requirements. Equipped with snap-type door lock and watertight opening at cabinet bottom for gravity drainage. Achieves purification and safe sampling of ultra-low temperature BOG samples, ensuring sample collection accuracy and operational safety.
Application Scope
The 2100 BOG Cryogenic Gas Sampling System is suitable for LNG receiving terminals, cryogenic gasification stations, offshore energy facilities (FSRU/FLNG), cryogenic air separation, energy peak shaving facilities, and other BOG sampling applications in various cryogenic environments.
LNG Receiving Terminals
Component sampling from storage tank BOG headers, recondensers, and export pipelines.
Cryogenic Gasification Stations
Sample gas pretreatment interface for high-pressure vaporizer downstream and calorific value measurement systems (GC).
Offshore Energy Facilities (FSRU/FLNG)
Component monitoring during ship loading/unloading operations, handling high salt spray and high vibration environments.
Cryogenic Air Separation
Sampling and temperature rise treatment for extremely low-temperature media in industrial gas production.
Energy Peak Shaving Facilities
Sample gas extraction at critical control points, ensuring real-time and accurate sampling data.
Core Advantages
Excellent Mechanical Vibration Resistance
PROBE 2100 adopts a heavy-duty reinforced design with extremely high mechanical strength in its insertion section, effectively suppressing vortex-induced vibration (VIV) generated by high-flow pipelines. Combined with the base reinforcing rib structure, it completely eliminates the risk of root fatigue fracture that traditional probes experience under long-term vibration.
Unique Two-Stage Expansion Liquid Removal Technology
Built-in multi-stage expansion chamber design utilizes the principle of sudden velocity drop to achieve gravity settling of sample gas. This design effectively intercepts and returns tiny liquid droplets entrained in the medium, ensuring that the sample gas entering the subsequent analysis system is completely dry and pure gaseous, greatly improving the representativeness of analysis results and extending the service life of precision instruments.
Deep Optimization for High-Humidity Conditions
Specifically designed for high-humidity environments with an ultra-large heat dissipation surface. Its longitudinal airflow design maintains smooth air convection even under severe frosting conditions, preventing heat exchange efficiency degradation caused by frost layer blockage, ensuring sample gas temperature always remains above the dew point.
Intrinsically Safe and Zero-Maintenance Design
PROBE 2100, as a passive device, relies on natural convection for heat exchange, with no electronic components or moving parts internally, conforming to Intrinsically Safe design logic. Its all-stainless steel and aluminum alloy materials can resist salt spray corrosion, achieving almost "zero maintenance" throughout its operational life.
Complete Sample Pretreatment Capability
SAMP 2100 Sampling Cabinet integrates pressure regulation functions, enabling purification and safe sampling of ultra-low temperature BOG samples, ensuring sample collection accuracy and operational safety.
