DRS2170-ABB Dynamic Reflux Sampler DRS2170

The DRS2170 solves complex sampling problems (such as hot, particulate laden, corrosive and otherwise nasty samples in a process for application engineering. The primary sample conditioning occurs in an in-situ fashion. Condensable components are removed and are used to support particulate removal before they can present problems in the sample transport system’s downstream components and the analyzer. The unit is a self-contained sampling device suitable for mounting at or near the process pipeline tap. The DRS2170 is now available with air cooled and liquid cooled to the sample handling systems.

　　Core Positioning and Technical Principles

　　Product Category: ABB PGC5000 series dedicated sampling device, specifically designed for the pretreatment of gas/liquid samples in complex industrial processes. It is compatible with equipment such as the PGC5007 total sulfur analyzer and the PGC5009 rapid GC, solving the sampling challenges of high-temperature, particulate, and corrosive samples.

　　Working Principle: Employs fixed-temperature distillation technology, achieving precise temperature control (±0.1℃) through a vortex cooler. This removes condensed components (such as water and heavy hydrocarbons) and particulate matter in situ, preventing data deviations or equipment damage to downstream analyzers (such as gas chromatographs and mass spectrometers) due to sample contamination or condensation.

　　Structural Design: Modular and compact design, supporting direct pipe installation; built-in automatic cleaning function reduces manual intervention; standardized flow path interfaces, concentrated on the right side, simplifying pipe layout; built-in automatic cleaning function, optimized control through temperature setpoints, extending equipment lifespan, compatible with industrial-grade piping systems.

　　Key Technical Parameters and Performance

　　Sample Processing Capacity:

　　High Throughput: Supports multi-flow path analysis (up to 4 channels), adaptable to multi-component simultaneous detection needs, such as sulfur compound analysis in the PGC5007 total sulfur analyzer.

　　Precise Temperature Control: Electronic PID controller supports local/remote temperature setting (4-20mA input or RS485 communication), temperature range covering -50℃ to 200℃ (depending on configuration).

　　Explosion-proof Certification: Complies with Class I Div 1, ATEX Zone 1 and other explosion-proof standards, suitable for hazardous areas (such as ethylene cracking furnaces, ammonia synthesis units).

　　Electrical and Air Supply:

　　Power Supply: 120/240 VAC, 50-60 Hz, startup power consumption ≤1600W, steady-state power consumption ≤900W.

　　Cooling Air Supply: Requires 60-100 psig clean, oil-free air, flow rate ≥60 SCFM.

　　Interfaces and Expansion: Supports 8 isolated 4-20mA outputs and 4 digital outputs, compatible with Modbus RTU and redundant Ethernet, and can be integrated with DCS systems for data linkage.

　　Communication and Expansion:

　　Industrial Communication: Supports redundant Ethernet, Modbus RTU, and DCS system integration for remote data monitoring and process linkage.

　　Compatibility: Works in conjunction with the PGC5000 series (B/C/5007/5009) intelligent analytical furnaces, achieving distributed control via intrinsically safe fiber optics; a single controller supports up to 4 DRS2170 units.

　　Application Scenarios and Industry Value

　　Petrochemical Industry:

　　Cracked Gas Analysis: Monitoring of hydrocarbon components (e.g., C1-C36 hydrocarbons) in ethylene cracking furnace and naphtha cracking gas to optimize catalytic cracking processes.

　　Ammonia Production: Detection of hydrogen-nitrogen ratio and impurities (e.g., CO, CO₂) in the ammonia synthesis process to ensure reaction efficiency.

　　Energy and Environmental Protection:

　　Natural Gas Processing: Analysis of total sulfur, including hydrogen sulfide and carbonyl sulfide, to meet ASTM D7041 standards.

　　Component Analysis: Detection of total sulfur, hydrogen sulfide, and carbonyl sulfide in natural gas, conforming to standards such as ASTM D7041.

　　Calorific Value Monitoring: Real-time monitoring of fuel gas calorific value to ensure combustion efficiency and environmental compliance.

　　Environmental Monitoring:

　　VOCs/NMHC Detection: Analysis of non-methane total hydrocarbons and volatile organic compounds in industrial waste gas to support environmental compliance and pollution source monitoring.

　　Flame Gas Monitoring: Real-time analysis of sulfides and hydrocarbon components in refinery flare gas to optimize combustion efficiency.

　　Power Industry: Analysis of dissolved gases (e.g., H₂, CH₄) in transformer oil to provide early warning of equipment malfunctions.

　　Equipment Fault Early Warning: Analysis of dissolved gases (H₂, CO, CH₄) in transformer oil to provide early warning of equipment malfunctions.

　　Fuel Quality Monitoring: Detection of sulfur content in fuel oil and fuel gas to ensure the safe operation of combustion equipment.

　　Compatibility and System Integration

　　PGC5007 Total Sulfur Analyzer: The DRS2170 serves as the front-end sampler, providing pre-treated samples to ensure high sensitivity detection of ppb-level sulfur compounds by the FPD detector.

　　PGC5000 Series Compatibility: Seamlessly integrated with the PGC5007 (Total Sulfur Analysis) and PGC5009 (Fast GC), enabling distributed control via intrinsically safe fiber optics; a single controller supports up to 4 column oven combinations.

　　PGC5009 Fast GC: With a fast-heating column design, it achieves rapid separation of C1-C36 hydrocarbons (ASTM D3710 gasoline analysis<4 minutes), improving analytical efficiency.

　　PGC5000B/C Intelligent Analytical Furnace: Supports online monitoring of complex samples (such as refinery middle distillates) through multi-channel, multi-component analysis, enabling unattended operation.

　　Installation Requirements: Must be installed vertically near the pipeline sampling point to ensure sample representativeness; requires an independent cooling gas source and electrical interface to avoid sharing resources with the main analyzer.

　　Maintenance Convenience: Modular design supports rapid maintenance; automatic cleaning function extends equipment life; remote diagnostic interface supports remote parameter adjustment and troubleshooting.
