LNG sampling white paper

EffecTech’s Dr Joey Walker had a paper featured in the July edition of LNG Industry. The paper, entitled Expanding the Degrees of Freedom looks at how to improve and optimise existing sampling systems for LNG inspection.

EffecTech, which already offers performance evaluations for natural gas instruments to ensure confidence in measurement, has focused on how to improve and optimise existing sampling systems using a combination of thermodynamic modelling and Monte-Carlo simulations, as part of the development of a sampling system inspection service for LNG customers.
