This uniquely rugged and simple design by Envent Engineering utilizes dual-beam technology for accuracy and stability.
CO2 is measured routinely in natural gas for product quality and process control purposes. Common ranges are from 0–5% for sales gas and up to 0–30% for inlet CO2 concentration. Some H2S removal chemical processes can be fine-tuned by slip stream as much CO2 as possible to gain volume but not so much as to exceed pipeline tariff limits of typically 2–4%. CO2 is also a combustion by product and needs to be quantified.
