FIX800 CO₂ Detector Delivery — Waste Treatment Resource Recovery Facility Carbon Emission Monitoring (Daejeon)

FIX800 Fixed CO₂ Detector — Waste Treatment and Resource Recovery Facility (Daejeon)

Hello from VPE Korea. This case covers the delivery of fixed CO₂ (carbon dioxide) gas detectors to a waste treatment and resource recovery facility in Daejeon.

Application — Carbon Emission Quantification

The purpose of this delivery was to measure CO₂ generated during the waste treatment process and quantify carbon emissions. Three detector points were installed to allow before/after treatment stage comparison.

System Configuration — Moisture Pretreatment + Diaphragm Pump + Stainless Tubing

High moisture levels are inherent to waste treatment processes. Each detector was paired with a moisture and dust conditioning unit.

Since the system is for experimental use, the conditioning train was assembled using 1/4" stainless Swagelok-style fittings to ensure zero gas leakage during servicing.

Commissioning — Leak Test and Span Gas Verification

After installation, all connections were leak-tested and system performance was verified using calibration gas.

Moisture Management — Critical Precaution for CO₂ Measurement

Electrochemical CO₂ sensors are highly susceptible to liquid moisture. Pretreatment units reduce moisture but cannot achieve 100% removal — if liquid water (not vapor) enters the sensor, it will corrode and fail. Strong pump suction can also draw condensate backward through tubing, so trap placement and conduit orientation must be carefully designed.

Frequently Asked Questions

Q1. Why is CO₂ measurement needed at a waste treatment facility?

Waste treatment processes — including fermentation, incineration, and decomposition — generate CO₂. Measuring concentrations before and after treatment quantifies the carbon emission intensity of the process, supporting environmental compliance and carbon reduction target management.

Q2. Why was the 0–50,000 ppm range selected?

Ambient CO₂ is approximately 400 ppm; waste treatment environments can generate concentrations in the thousands of ppm range. The 0–50,000 ppm range covers the full spectrum from ambient baseline to high-concentration process conditions — enabling meaningful before/after comparison measurements at all three installation points.

Q3. Why can't the pretreatment unit remove moisture completely?

Silica gel and cooling-based pretreatment units remove most moisture but have physical limits. In high-humidity waste treatment environments, the pretreatment unit can saturate. Periodic inspection of the conditioning unit, careful trap and drain design, and correct conduit orientation are all required to prevent liquid water from reaching the sensor.

Q4. Why are stainless Swagelok-style fittings used?

Stainless steel is resistant to corrosion by acidic gas streams, including CO₂ mixed with other process gases. Compression-style fittings provide high-integrity, leak-free connections at every joint. In experimental laboratory setups, preventing any gas leakage is a safety priority — these fittings are the appropriate choice.

Q5. How many gas types can the FIX800 be configured to measure?

The FIX800 supports over 50 sensor types — including CO₂, HCl, HF, HCN, Cl₂, VOC, NH₃, and many others. Integrated LED display board and smartphone real-time monitoring configurations are also available.
