Refinery Emissions Monitoring & Analysis
Procal supplies both refinery process and refinery emissions monitoring analysers to meet a wide range of applications.
Crude Oil Heaters / Furnaces / Incinerators
Crude Oil Heaters / Furnaces / Incinerators
Procal 2000 measures products of combustion and can accommodate changes caused by variations in the make up of off-gas fuel. 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.
| Gas | Ranges to Suit Process |
| SO2 | 0 – 2,000 ppm |
| NO | 0 – 500 ppm |
| NO2 | 0 – 500 ppm |
| H2O | 0 – 15% |
Power Plant– Electricity and Steam
Procal 2000 is the ideal field-proven device to monitor emissions from refinery power plants. The instrument is compliant with international standards therefore meeting the stringent requirements of Environment Agencies.
| Gas | Ranges to Suit Process |
| CO | 0 – 200 ppm |
| NOx | 0 – 500 ppm |
| NO2 | 0 – 500 ppm |
| CO2 | 0 – 15% |
Klaus Unit
Capable of reliably measuring the high concentrations of SO2 found in a Klaus Unit, Procal 2000 can be offered with special corrosion-resistant materials such as Hastelloy ‘C’. Procal 2000 is the only in-situ IR analyser on the market that is available with optional ATEX / IEC approval for use in ZONE 1 Hazardous Areas such as those found in many refinery applications.
| Gas | Ranges to Suit Process |
| SO2 | 0 – 2% |
| H2S | 0 – 2% |
Catalyst Cracker Vent
This is an application for which the Procal 2000 analyser is well suited. In cases where dust levels in the sample are high, the sintered filter assembly can function well even at levels of a few g/m3.
In addition to ATEX / IEC approved analysers, Procal offer a range of accessories suitable for installation in hazardous areas. For example, steam-heated probes and bypasses can be used to ensure that the sample temperature is maintained above the acid dew point.
| Gas | Ranges to Suit Process |
| SO2 (normal) | 0 – 700 ppm |
| SO2 (plant upset) | 0 – 14,000 ppm |
| NO | 0 – 300 ppm |
| NO2 | 0 – 250 ppm |
