A Smorgasbord of measurements

Publications / Tech - May 1, 2018

Gas concentration measurements for process control, emissions monitoring and safety purposes are ubiquitous in refineries. The instrumentation is dominated by gas chromatographs, but over the past few years another technology has slowly found its way into many refineries: gas analysers based on tunable diode laser absorption spectroscopy (TDLAS).

This article is the first of a series of application studies for TDLAS analysers in refineries, which provides a short introduction to the underlying technology and a brief overview of refinery-related applications.
In the October 2018 issue of Hydrocarbon Engineering, the first of several application examples will be discussed in detail: the usage of TDLAS analysers for in-situ tail gas analysis in sulfur recovery units (SRUs).

NEO Monitors’ Hydrogen lineup

Hydrogen will become one of, if not the most important energy source in the coming decades. It isalso used in industry, for example as a feedstock for chlorine and ammonia production. NEO Monitors’ laser-based gas measurement technology offers the possibility of performing theconcentration measurement without physical contact with the gas. This combined with the advantages […]

New Opportunities in Mid-Infrared Emission Control

Tunable laser absorption spectroscopy (TLAS) has been well accepted as a preferred measurement technique for many industrial applications in recent years, especially for in situ applications. Previously, mainly near-infrared lasers have been used in TLAS sensors. The advent of compact mid-infrared light sources, like quantum cascade lasers and interband cascade lasers, has made it possible […]
