The MERLIN separator for gas analysis systems is an innovative, patented separation technology that separates liquids and particles from a gas. It preconditions gas samples and protects on-line gas analyzers by preventing the transfer of liquids and solid particles.
The design of this separator ensures optimum separation even at low flow rates (1 liter/min), and the geometry and surface quality of the separator head prevent the formation of fine liquid droplets that could find their way back to the analyzer.
Without the use of a filter cartridge (sintered stainless steel or textile), the MERLIN gas separator effectively separates condensate films (oil vapors) and particles (up to 10 microns) from the gas stream by centrifugal force. The difference in density between a gas and solid or liquid particles enables centrifugal separation. The components are carried along the wall and exit the separator via the bypass. The treated gas sample exits at the top of the separator to the analyzer.
Unlike traditional filtration systems, which require frequent replacement of filter elements, MERLIN considerably reduces maintenance costs. There's no risk of clogging, and no spare parts to change.
Today, this separator is successfully used in a wide range of applications, such as H2S measurement in fuel gases, oxygen measurement in ethylene oxide units, scrubbers, syngas, removal of oily mists in gas chromatography, and condensate protection for paramagnetic oxygen analyzers.
