Nitric Acid Plant Process Control

Nitric Acid Plant Process Control

The P2000 emissions analyser measures Oxides of Nitrogen for process control purposes, typically upstream of the N2O abatement reactor where typical pressures can be as high as 10 bar. The analyser can be supplied in both in-situ and bypass configuration to suit customers’ requirements. P2000 has an integral auto-zero and calibration facility and, in order to meet the requirements of the Nitric Acid process, the system can be supplied with an auto-ranging capability to monitor plant upsets. The instrument is compliant with international standards and complies with the stringent requirements of Environment Agencies.

The P2000 analyser range is well suited to applications with a high dust load. Sintered filter technology is used to pre-clean the sample gas. No maintenance is required during operation and there are no additional consumables, ensuring a simple and well tested solution offering up-time for control of your plant.

P2000 is heated to prevent condensate build-up at low sample temperatures. The heated probe option is especially suited to this application as it efficiently deals with variations in process temperature. It also keeps the probe hot, ensuring immediate availability when the plant is restarted after an outage.
