Nitric Acid

NITRIC ACID

Nitric Acid
Nitric Acid Process Gas Emissions Monitoring & Analysis
High Pressure Applications (>)2 bar

The Protea 2000 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.

Typical Range

NO

0 – 1000 ppm

NO2

0 – 300 ppm

N20

0 – 1,000 ppm

Stack Emissions including Ammonia 

Protea 2000 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 Protea 2000 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.

Typical Range

NO

0 – 500 ppm

NO2

0 – 2,500 ppm

NH30

0 – 100 ppm

Stack Emissions including Hydrocarbons

Protea 2000 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.

Typical Range

CO2

0 – 20%

NO2

0 – 1250mg/mg3

N2O

0 – 1.5%

CO

0 – 1250mg/mg3

NOx

0 – 2500mg/m3

CH40

0 – 6000mg/m3

Hazardous Areas

For Hazardous Area locations associated with high Methane levels, Protea 2000 can be supplied with ATEX / IEC approvals including accessories suitable for installation in such areas. For example, steam-heated probes and bypasses ensure that the sample temperature is maintained above the acid dew point.

These in-situ analysers are designed to provide high levels of reliability, exceeding the Environmental Agency’s requirements for monitoring availability.

Typical Range

N20

0 – 5%

NO

0 – 500 ppm

NO2

0 – 250 ppm

NH3

0 – 200ppm

CH40

0 – 200ppm

The Protea controller has a capability to control up to six analysers and includes data logging and reporting.

We offer an innovative range of opacity, dust, particulate and smoke monitors to suit a variety of continuous gas emission applications such as boilers, filter bag houses, incinerators and other industrial processes.

DynOptic opacity monitors use the light transmission technique to measure the visible opacity of exhaust gas in a duct, stack or flue, in which a high intensity light beam is projected across the stack. Click here for more information.

DynOptic dust monitors use the innovative Dynamic Detection Principle (DDP) to measure dust and particulate within exhaust gases from various manufacturing processes. Click here for more information.

DynOptic particulate monitor is an optical instrument designed to measure the concentration of dust or particulate matter in an exhaust gas. When calibrated against standard reference measurement reading as mass concentration [mg/m³]. Click here for more information.
