DUALSULF™ H₂S/TOTAL SULPHUR ANALYSER

FEATURES

  • Separate channels for both H₂S and total sulphur : Reduces capital expenditure
  • Wide range capability : Measures between 0-250ppb to 0-2000ppm
  • Simultaneous analysis for H₂S and total sulphur: No loss of measurement
  • Self-regeneration of catalyst: Increases instrument availability
  • Hydrogen/process sample shut-down system Increased safety
  • Response times as low as 20 seconds Ideal for plant control
  • ATEX approved for hazardous areas Suitable for onshore and offshore applications

PRINCIPLE OF OPERATION

The metered process sample is split into two arms. One arm is directed to a detection module where the H₂S is measured using interference free ASTM approved tapes. The gas is humidified and passed over a sensing tape which becomes stained by the H₂S, the amount of staining being proportional to the H₂S concentration. A focused LED and single photo detector system continuously measures the darkening stain and the analyser reports this as a linear 4-20mA output of the concentration of H₂S. The second arm is mixed with a continuous flowing stream of hydrogen. The mixed gases are heated together in a reducing catalytic furnace at a temperature between 650-1050°C (depending on application), where the sulphur compounds are converted to H₂S. The resulting H₂S is measured using interference free ASTM approved tapes. Since the patented catalytic element is self-regenerating, there is no need for manual or automatic regeneration of the furnace. No carbon build-up occurs in normal operation, even in the presence of unsaturated hydrocarbons. The local LCD display provides the current H₂S / total S readings, alarms if any and failure indicators.

CONFIGURATION

The analyser consists of:

  • One Detection Module for measurement of H₂S in a gas stream
  • One Conversion Module and one Detection Module to measure Total Sulphur in a gas stream
  • One Electronic Module for controlling all the above modules
  • Measurement specific to Total Sulphur & H2S

the technology

Our innovative photoacoustic spectrometer is based on patented Helmholtz resonance cell combined with Tuneable Diode Laser or Quantum Cascade Laser suitable for trace gas and bulk gas detection.

The Laser sources are specifically chosen to provide selective and interference-free measurements.

using  NIR and MIR—IR spectroscopy

Our technology offers fast, high resolution spectroscopy to detect and identify a range of molecules in the Near-IR and Mid–IR wavelength range. Coupled with Tunable Diode Laser (TDL) spectroscopy, a single instrument is now able to broaden insight and monitor both the near and mid-infrared range of spectroscopic light.

In Mid-IR a large choice of absorption peaks that can be used. One example is shown below. The absorption peak in MIR is much bigger than in NIR. The LOD is several 0,1 ppm here.

many advantages

  • No Interference: selective laser sources
  • Versatility: The design of the patented PAS cell is independent of the gas detected. To change the molecules detected, one requires just to swap or to tune the QCL to the wavelength of the specific absorption band of the new molecule.
  • Zero-Background Technology. as there is no signal as long as there is no gas.
  • Robustness: The photoacoustic cell platform does not have any moving parts and is not sensitive to environmental vibrations because of the high-frequency acquisition rate. There are no wavelength-specific optics or mirrors.
  • High sensitivity: The PAS can detect ppb levels with a 10-cm path length.
  • Fast sensitivity response: due to small internal volume
  • Larger than 5 orders of magnitude measurements: 6 orders of from ppb to a few %.
  • Linearity of the PAS Signal: over the 5 orders of magnitude (i.e. ppm -%) without any deconvolution or interpolation. A calibration function is used outside this linear range.
  • Specific measurements: accurate and specific measurements in complex gas matrices.
  • Use of Mid IR lasers (QCL): Aerovia’s PAS technology use QCL laser in the Mid IR spectral range. It gives access to fundamentals rays (larger peaks) of most molecules and to the detection of large molecules.

NOVASULF™ II TG500

Duty: To measure the concentration of H2S in a process gas stream.
The principle of operation is as follows. A reel of paper tape impregnated with lead acetate is exposed to the gaseous process sample in the sample chamber. Hydrogen sulphide (H2S) in the process sample reacts with the lead acetate, after acidification, to form lead sulphide (PbS), a brown compound that stains the tape.

The higher the concentration of H2S the darker the stain. A focused LED and single photo detector system continuously measures the darkening stain and the analyser reports this as a 4-20mA output of the concentration of H2S.

Incremental measurements are made on the same spot until saturation occurs, when the tape is advanced to a fresh portion of tape. This avoids the need for frequent zero or span calibrations.

The benefits of this technology can be summarised as follows:

  • Measurement specific to Total Sulphur & H2S
    No interference from other components

PRINCIPLE OF OPERATION:

A reel of paper tape impregnated with lead acetate is exposed to the gaseous process sample in the sample chamber. Hydrogen sulphide (H₂S) in the process sample reacts with the lead acetate, after humidification, to form lead sulphide (PbS), a brown compound that stains the tape. The higher the concentration of H₂S is the faster the darkness of the stain is. A  bi-directional fibre optic measures the darkening stain and the analyser computes concentration of H₂S.

Incremental measurements are made on the same spot until saturation occurs, when the tape is advanced to a fresh portion of tape. This avoids the need for frequent zero or span calibrations.

SPECIAL FEATURES

The Photoacoustic Spectroscopy (PAS) has many advantages compared to

other more classical IR spectroscopy techniques.

  • Versatility:  The design of the patented PAS cell is independent of

the gas detected. According to the operating principle of the PAS,

the soundwave is generated by the molecules specifically absorbing

a modulated IR light. To change the molecules detected, one

requires just to swap or to tune the QCL to the wavelength of the

specific absorption band of the new molecule.

  • Zero-Background Technology. This technique is called a

zero-background technology as there is no signal as long as there

is no gas.

  • Robustness:  The photoacoustic cell platform does not have any

moving parts and is not sensitive to environmental vibrations because

of the high-frequency acquisition rate. There are no wavelength-specific

optics or mirrors.

  • Atmospheric pressure measurements:  the gases to be analysed flow

though the cell without any specific pressure conditioning.

  • High sensitivity: The PAS can detect ppb levels with a 10 cm path length. Depending on the power of the QCL, ppt levels can be reached.
  • Small internal volume: the internal volume of the PAS cell is small (approx. 50 cm3).  This volume could be further reduced as the sensitivity response is inversely proportional to the cell dimensions.
  • Larger than 5 orders of magnitude measurements: PAS measurements can be carried out routinely over 6 orders of magnitude (from ppm to a few %).
  • Linearity of the PAS Signal: The response of the PAS cell is linear (< 1 % deviation / linear response) over the 5 orders of magnitude (i.e. ppm -%) without any deconvolution or interpolation. A calibration function is used outside this linear range.
  • Specific measurements: PAS in the IR spectral range allows for accurate and specific measurements of most gases even in very complex gas matrices.
  • Operations at a temperature between -10°C et 40°C and temperature variations DT < 1°C/h

APPLICATIONS:

With its wide-ranging ability to measure H₂S in liquids from % levels down to ppm levels, the HL500 range of H₂S process analysers can be utilised in many process industries, including the measurement of dissolved H2S in crude oil.

 

PRINCIPLE OF OPERATION

The Analyser consists of a stripping system coupled with a NovaSulfTM H2S Analyser. The liquid sample enters the top of an insulated, heated sample handling cabinet via a flow controller to maintain a constant sample flow. Nitrogen flows down a vertical tube to a sintered plug located within the liquid and then flows up through the liquid. As the nitrogen mixes with the liquid hydrocarbons it strips out the dissolved H2S in the liquid.  

 

The degassed liquid falls into a reservoir and then to the drain. At the same time, the nitrogen containing H2S in proportion to that in the original liquid is piped directly to the NovaSulfTM HG 500 series H2S Analyser to be measured.

WATERSULF™ SERIES

The WATERSULF™Series analyser is dedicated to the measurement of dissolved sulphides in water up to pH 8.5.

  • The concentration of Sulphides in water depends on the sample pH.
  • Between 0 and 6 the H2S is at the maximum concentration.
  • Between 6 and 8.5 the H2S concentration decreases.
  • Between 8.5 and 11 no H2S is present in the water.
  • Above 11 S־־ concentration increases.
  • Between 4 and 8.5 the HS־ increases.
  • Between 8.5 and 11.5 the HS־ is at the maximum concentration.
  • Above 11.5 the HS־ concentration decreases.
  • At neutral pH (7) only H2S and HS־ are present.

The measurement principle is based on a variation of HENRY’s law :
the weight of any gas dissolved in a definite volume of liquid is proportional to the partial pressure the gas exerts above the liquid at a constant temperature.

The benefits of this technology can be summarised as follows:
The H2S sensor is immerged in the water. The sensor is equipped with a propriarity membrane. Due to the partial pressure effect, the membrane is only pervious to gases. No liquids, ions or solids can penetrate the sensing part.
The sensor contains a buffer solution with a redox catalyst and 3 electrodes. A defined polarization voltage is applied to the electrodes in order to give a well defined concentration ratio of the oxidized/reduced redox catalyst. The H2S reacts, first chemically in presence of the redox catalyst to form a reaction product. Then, the electrochemical oxidation of the reaction product takes place at the measuring electrode.

Due to the polarization voltage effect, the system can adjust the concentration ratio. The resulting current is proportional to the dissolved molecular amount of H2S present in the sample.
The pH pressure and temperature sensors are also immerged in
