GAS-70: Gas content
Closed loop control of deaerator and defoamer chemicals
The main application of the GAS-70 Gas Analyzer is closed loop control of deaerator/defoamer chemicals in pulp and paper production. By measuring free and dissolved gas content online, runnability problems caused by increased gas content can be corrected within a short time. On the paper machine, typical sampling points are the headbox recirculation line and the white water; in a pulp mill, GAS-70 also samples at brown stock washing to optimize the washing process.
GAS-70 is cloud-ready, giving remote access to readings and remote troubleshooting, not only at the panel.
BTG has 25 years of experience in gas measurement, helping customers turn data from their units into a stronger value case and, over time, lower energy cost.
