Crucial factors for successful analyzer implementation include selecting the best available process analyzer technologies, a good understanding of the process conditions and performance requirements, and suitable-designed sample conditioning and validation systems. The performance is determined by the combined strength of all the components. Our experienced engineering, production, testing and service team is committed to collaborate with our clients and partners, to implement analyzer systems with the required functionality at the lowest possible cost of ownership. Founded in 1978, we provide complete process analyzer solutions based on our customers need. A few of our online analyzer solutions, are highlighted below.

LNG analysis and sampling solutions

For LNG custody transfer it is now common practice to determine the composition and gross calorific value of delivered LNG by direct online analysis plus indirect lab analysis methods. The handling of the LNG before analyzing can have significant effect on the representivity of the sample. A sample which is not representative results in incorrect measurement which can have a significant financial impact. Hobré Instruments successfully supplied systems for these extreme conditions. This project scope was realized by:

  • Take-off probe and vaporizer
  • Automatic and spot sampling system
  • Wobbe index analyzer
  • Process gas chromatograph
  • Sample conditioning system
