Analyzers of the physical properties of hydrocarbon products

Continuous analyzers to determine distillation curve, fog points, freezing, flash, color, viscosity and other components in accordance with ASTM and ISO standards.

Monitoring of blends

NIR, FTIR and RAMAN analyzers for monitoring blending processes Chemometric modelling to match laboratory analyses.

The Claus Process

Analyzers for reliable monitoring of H2S, SO2, COS and other components required for Claus process control with minimal maintenance requirements.

Sulphur in gases

Monitoring of H2S and other sulphur components as well as total sulphur in various gas mixtures and off-gases. Depending on the application, the analyzers work on the principle of chromatography, TDL, UV absorption or acetate strip.

Hydrocarbon Tank Draining

Reliable capacitive system for automatic opening and closing of the release valve for tank draining. TK Drain is a replacement for the older Pautbac II model, production of which has been discontinued.

TOC / COD Analysis

TOC and COD analyzers based on superoxidation at extremely high temperatures and pressures.
All liquid and solid compounds are analysed allowing closest matching of laboratory results.

Leakwise Oil Layer Monitors

to detect oil / hydrocarbon leakages, and layers on water

• Continuous on-line monitoring with self-diagnostics
• Certified for operation in hazardous areas. The sensors are Intrinsically Safe
• Proven long-term reliability – even if the sensor is coated with dirt or oil, variations in water salinity,temperature, liquid level or liquid turbulence
• Low maintenance – No parts to replace, almost maintenance free, no cleaning is required after aspill
• Versatility – can be easily installed in sumps, retaining tanks or other containments
• Thin oil layers detection, from 0.3 mm in all conditions
• Immediate detection – fully complies with 30 seconds requirement of FM Class 7745 standard
• Ability to operate even without water
• Thickness measurement – not only sheen detection
• Oil layer trend is indicated during spill buildup or cleanup
• Alarms and controls – visual or audible alarms, messages, and controls that activate skimmers,discharge pumps, valves, or other containment measures

Monitoring hydrocarbons in water

Instruments for the analysis of the presence of hydrocarbons in process, cooling and waste waters as well as in condensate.
A wide range of instruments designed to monitor both aromatic and aliphatic hydrocarbons.

Sulphur in Liquids

Monitoring the Sulphur content of hydrocarbon liquids. The analyzers work on the principle of UV absorption or XRF.

Water cut monitor

Reliable monitoring of water content in dielectric liquids

Flare Gas Combustion Control

Heat value and WOBBE Index monitors for different gas mixtures.

Analysis of oxygen, hydrocarbons, CO and CO2 in refineries and ethylene units

Analyzers based on tunable laser, RAMAN technology and IR absorption for reliable analysis in refinery processes and ethylene units.

Compact analyzer of natural gas odoration

Analyzers to monitor odorants in natural gas. The instrument is not influenced by hydrogen mixed to natural gas.

Analysis of hydrogen in natural gas

H2SCAN instruments use a unique palladium-nickel measuring cell technology that selectively measures the hydrogen content in the monitored medium. It does not require any additional infrastructure, additional measurements, or auxiliary media.

Stack Gas Emission Monitoring

Automatic emission monitoring systems with QAL1 certificate in accordance with EN14181.

Trace heating

Tank and pipe heaters with fixed or electric heating. You will find more information in a separate section. Electric heat tracing products.

Flow Monitoring of Gases and Liquids

Thermal conductivity-based instruments for monitoring the flow of polluted gases with variable humidity and composition

• Improved Constant Temperature technique
• Auto adjusts power to protect the sensor at high
  temperatures & enables fast return to service
• Eliminates sensor burnout

Flow Monitoring of Solids

• Electromagnetic field in the sensor pipe (condensator).
• Field capacity is measured continuously.
• Bulk material in the sensor has a higher dielectric permittivity than air and increases the field capacity.
• The changing capacity is proportional to the concentration of the bulk material.
• Calibration by:
  • reference weighing
  • filling the sensor pipe (externally or in process)

Velocity

• Runtime measurement at two sensors with known distance
• Comparation of the signals with cross correlation function=Dt
• v=d/Dt
• No calibration

Portable and Stationary Cameras to monitor gas leaks, flares, heat and fires
