Product Description

The ABB SCC-F 23212-0-110310​ is a high-performance Sample Gas Feed Unit manufactured by ABB, a global pioneer in industrial automation and measurement technology. This unit is a critical component within ABB’s analytical instrumentation portfolio, specifically designed for precise sample gas conditioning and delivery. It acts as the reliable interface between a process sampling point and a continuous gas analyzer, ensuring that the gas sample presented to the analyzer is clean, dry, and at the correct flow rate and pressure for accurate and stable measurement .

Application Scenarios

In a coal-fired power plant’s Continuous Emissions Monitoring System (CEMS), regulatory compliance hinges on measuring flue gas constituents like SO₂, NOx, and CO with extreme accuracy. The hot, wet, and particulate-laden flue gas is utterly unsuitable for direct analysis. This is where the ABB SCC-F 23212-0-110310​ proves its critical value. Installed in a protective enclosure near the sampling probe, the SCC-F 23212-0-110310​ receives the raw sample. Its dual-path design allows one path to transport gas to the analyzer while simultaneously managing condensate removal in the other, preventing liquid from damaging sensitive analyzer components. By actively controlling the sample flow and removing moisture, the unit transforms a problematic gas stream into a conditioned, representative sample. This scenario highlights the unit’s core value: it directly solves the pain points of analyzer malfunction, data drift, and regulatory non-compliance by providing a robust, first line of defense in sample conditioning, ensuring that the analyzer “sees” only what it needs to for a reliable reading .

Technical Principles and Innovative Values

The ABB SCC-F 23212-0-110310​ is engineered not just as a simple manifold, but as an intelligent sample conditioning node that protects capital-intensive analyzers and guarantees data integrity.

Innovation Point 1: Active Dual-Path Condensate Management.​ Unlike passive knock-out pots, the SCC-F 23212-0-110310​ utilizes two actively controlled gas paths. One path delivers the sample to the analyzer, while the parallel path is dedicated to condensate evacuation, often integrated with a condensate pump. This proactive separation ensures that liquid water, a major source of corrosion and measurement error, is never allowed to travel towards the analyzer, significantly extending sensor life and maintenance intervals .

Innovation Point 2: Integrated Digital Diagnostics and Communication.​ The unit features a digital communication port (RS232) that seamlessly integrates with the controller of ABB’s Advance Optima series analyzers. This allows the SCC-F 23212-0-110310​ to transmit vital status information and alarm signals (e.g., flow fault, high condensate level) directly into the analyzer’s control system. This integration enables predictive maintenance, remote troubleshooting, and centralized alarm management, transforming the unit from a dumb hardware component into a smart, communicative asset within the analytical loop .

Innovation Point 3: Modular, Service-Friendly Design for Harsh Environments.​ Built with stainless steel​ and boasting an IP65​ rating, the unit is constructed to survive in outdoor analyzer shelters or harsh plant environments. Its design emphasizes serviceability: key components like filters, flow meters (rotameters), and valves are easily accessible without specialized tools. This modularity minimizes downtime during routine maintenance or component replacement, reducing the total cost of ownership over the system’s lifecycle .

Application Cases and Industry Value

Case Study: Enhancing Analyzer Uptime in a Petrochemical Crack Gas Analysis Loop

A major petrochemical plant was experiencing chronic reliability issues with its online gas chromatographs (GCs) analyzing cracker effluent. The sample stream, containing heavy hydrocarbons, would frequently condense and plug sample lines and valve assemblies within the GC, leading to weekly maintenance interventions and unreliable composition data critical for process optimization.

The solution was to retrofit ABB SCC-F 23212-0-110310​ units as primary sample conditioners ahead of each GC. The units were equipped with optional heating to keep the sample above its dew point during transit. Their robust condensate management paths actively removed any liquid formation before it could reach the GC.

The plant’s lead instrument engineer reported: “Installing the ABB SCC-F 23212-0-110310​ was a game-changer. The active condensate control eliminated the plugging issues that plagued us for years. Our GC maintenance intervals have extended from weekly to quarterly, dramatically increasing analyzer availability. The reliable, dry sample now provides the consistent data our process engineers need to optimize yields. The SCC-F 23212-0-110310​ paid for itself in reduced maintenance labor and avoided production losses within the first few months.”

Installation, Maintenance, and Full-Cycle Support

Installation of the ABB SCC-F 23212-0-110310​ is straightforward for qualified personnel. The compact unit can be mounted in a standard 19-inch rack (using a half-width slot) or directly on a wall within an analyzer shelter. The process involves connecting the sample inlet line from the probe or probe filter, the outlet line to the analyzer, and the drain line from the condensate path to a safe disposal point. Electrical connection requires a clean 24VDC supply (or an appropriate AC/DC converter). Finally, if digital integration is required, the RS232 communication cable is connected to the analyzer’s controller board. Commissioning primarily involves setting the desired sample flow rate using the integrated needle valve and rotameter, and verifying leak-tightness of all connections.

Routine maintenance is minimal and designed for ease. The primary task is periodic inspection and replacement of the in-line particulate filter element to protect the unit’s internal components. The condensate trap or pump chamber should be checked and emptied as needed. The modular design allows individual components like valves or the flow meter to be serviced or replaced without removing the entire unit from service. The IP65 rating ensures internal components are protected from environmental contaminants.
