Separator - Pressure vessels - Quiri
To avoid bringing a liquid phase to a compressor, or extracting a condensed part of a gas mixture, different types of separators are directly integrated into our exchangers or pressure tanks.

Technical specifications :

In various gas treatment or steam conditioning processes, the flows circulating at the inlet or outlet of heat exchangers are sometimes loaded with liquid or solid particles. As an example, a common application consists in carrying out a first dehumidification step at the outlet of an air cooler. Indeed, by cooling atmospheric air (characterized by its relative humidity), a condensation of part of the vapour contained takes place. This condensed steam can be found in the form of droplets or mist depending on the flow regimes (separate phase, intermittent, dispersed,...) and the separation device must be able to collect the liquid phase on one side and allow the gas to continue its journey through the process. The separation can be done by devices such as cyclone or coalescing mats. In other situations, if we take the case of a steam or refrigerant in a thermodynamic cycle, it is necessary to avoid dragging a liquid phase towards a compressor or a turbine. In these cases the separators can be of the coalescing mat or baffle type. In all these applications, the pressure drop must be controlled for reasons of the overall performance of the installation.
