Process H2S and Sulphur measurement
Process H2S and Sulphur Measurement
Solutions for measurements from low ppb levels up to percent levels of H2S/Sulphur in gasses and liquids are available with design based on a long experience. Our solutions include a range of measurement technologies, in combination with suitable sample handling and calibration/validation systems.
H2S is a dipole molecule, and in the low ppb and ppm levels it is easily absorbed by the sample wetted parts in the sample handling system. Carry over of products from the process line into the sample line could occur with all the consequences of wrong H2S measurement.
As a result of the above, a correct design of the sample handling system is key to the success of the analyzing system. Our solutions are designed for your specific process conditions and based on more than 25 years of experience in this field.
Key features of our systems are:
- Sample take-off assemblies removing the liquid and particle carry over products from gas streams as close as possible to the process. Special Multiphobic filters are developed to retain any process and particle liquid carry over to the sample lines , sampling system, and analyser,
- Selected sample wetted parts to minimise absorption of the low levels H2S,
- For liquid applications we offer low maintenance free particle and water removal systems,
- Analytical method is selected to meet your application requirements taking into account: Matrix and Phase diagram of your process stream, response time and accuracy, maintenance and availability,
- Validation and calibration facilities,
- Protective cabinets and shelters to meet your environmental/ambient condition,
- Analysers from selected manufactures with proven products and support.
Our applications include:
- Low ppb and ppm for catalyst protection to improve catalyst life and efficiencies,
- Pipeline and corrosion protection (natural gas and crude oil),
- Crude oil and Natural Gas production,
- Monitoring of H2S removal systems (scavenger, amine, caustic, solid absorber),
- Olefin and polymer production,
- CO2,
- LPG and LNG,
- Petroleum products, gasoline, kerosene, diesel, fuel oil,
- Emission reduction (Fuel-gas, Flare-Gas, Fuel-oil),
- A recent project covers the supply of H2S analysers on a 210.000 barrels/day crude oil production platform. These analysers are used in a SIL2 rated system to protect the export pipeline against H2S levels above 11 ppmWt.
Our services include: application reviews, designs, construction, testing, start-up, training and routine maintenance work.
We have partnerships with world leading companies in Process Analysis.
