Takeaways

• 😀 The AER sampling system includes both glass and stainless steel 316 components for nozzle and probe assemblies.
• 😀 The tapered nozzle inlet is designed to pull in gas samples efficiently.
• 😀 Probe assemblies consist of a combination of glass or stainless steel liners, heater assemblies, S-type pedo tubes, extra gas sampling tubes, and thermocouples.
• 😀 Proper connection components include nuts, Teflon ferrules, unions, O-rings, and backer rings to ensure a secure assembly.
• 😀 The filtering system integrates the probe liner, cyclone bypass, filter holder, double L adapter, and thermocouple, all fitted into the heater box.
• 😀 The condensing system uses an impinger (cold) box with multiple impingers and U-tube connections to cool gas and pass it through reagents while maintaining gas below 20°C.
• 😀 The fully assembled sampling train includes an umbilical cord connecting the heating box, gas sample lines, S-type pedo tubes, and thermocouple lines to the metering console.
• 😀 The metering console contains a dry gas meter, valves, pump connections, thermocouple jacks, vacuum gauge, timer, thermal controllers, temperature sensor, and manometer for monitoring and controlling the sampling process.
• 😀 Calibration is essential for the nozzle, S-type pedo tubes, dry gas meter, temperature sensor, and orifice tube inside the metering console.
• 😀 Leak checks on pedo lines and sample lines are critical before operating the AER sampling system to ensure safety and data accuracy.
• 😀 The system is designed for US EPA compliance, emphasizing material choices, accurate temperature monitoring, and proper assembly and calibration procedures.

Q & A

What is the purpose of the AER sampling video presented by Samur?

The video is intended to introduce and explain the components of the US EPA sampling train, demonstrate how these components fit together, and describe the operation of the metering console.

What materials are used for the nozzles and probe liners in the AER sampling train?

The nozzles and probe liners are available in glass and stainless steel 316, with the stainless steel being the equivalent to the glass components.

What components are used to connect the probe liner to the nozzle?

The connection uses a nut, Teflon ferrule, union, O-ring, and backer ring.

What elements are included in the combination probe assembly?

The combination probe assembly includes the glass probe liner, heater assembly, S-type PEO tubes, extra gas sampling tube, and thermocouple.

How does the filtering system work in the sampling train?

The filtering system consists of a probe liner connected to a cyclone bypass, clipped onto the filter holder, and attached to a double L adapter with a thermocouple to measure gas temperature. The assembly is then placed inside a heater box.

What is the purpose of the condensing system in the AER sampling train?

The condensing system, housed in a cold box with impingers, cools the gas samples to below 20°C before they exit the system.

How many impingers are inside the cold box, and what is their sequence?

There are four impingers: a plane impinger, a Greenberg-Smith impinger, and two additional plane impingers, connected sequentially to ensure proper gas cooling and reagent contact.

What functions are managed by the AER sampling metering console?

The metering console manages dry gas measurement, power distribution, gas flow control via valves, thermocouple readings, vacuum monitoring, timing, temperature control for probe and oven heaters, and monometer readings.

Which components require calibration before operating the sampling train?

The nozzle, S-type PEO tubes, dry gas meter, temperature sensor, and the orifice tube inside the metering console all require calibration.

Why is it important to check for leaks in the PEO lines and sample line?

Leak checks ensure accurate sampling and measurement by preventing gas loss and maintaining system integrity.

What role does the thermocouple play in the sampling train?

Thermocouples monitor the gas temperature at various points, including the filtering system and condensing system, to ensure proper sample handling and accurate readings.

What is the final step before operating the AER sampling system?

After assembling all components, calibrating instruments, and performing leak checks, the system is ready for operation according to US EPA sampling methods.
