Résumé

Control valves are frequently used in chemical and petrochemical plants to control medium mixtures that comprise a gas/vapour phase as well as a liquid phase as they enter the valve. The IEC 60534-2-1 Standard is primarily applied to calculate the required valve flow capacity for single-phase media in the form of gases or liquids. However, this standard does not apply to multiphase flow. A standardized sizing model does not exist even in literature. As a consequence, plant operators and manufacturers employ various published methods according to their own experience, which may lead to considerably different results depending on the operating and medium data involved. This article proposes a new approach - the HNE-DS method - to size control valves that handle multiphase mixtures consisting of gases/vapours and liquids.
