(EN) MIXED REFRIGERANT SYSTEM FOR NATURAL GAS PROCESSING
(FR) SYSTÈME DE RÉFRIGÉRANTS MIXTES POUR TRAITEMENT DE GAZ NATUREL
Abrégé
(EN)
A simplified mixed refrigerant system for natural gas processing which eliminates the need for storing, mixing and adjusting the individual hydrocarbon components of the refrigerant thereby rendering what are normally complex systems more practical for the natural gas liquid recovery industry.
(FR)
L'invention concerne un système de réfrigérants mixtes simplifié pour le traitement de gaz naturel qui élimine la nécessité de stocker, de mélanger et d'ajuster les composants d'hydrocarbures individuels du réfrigérant, rendant ainsi des systèmes normalement complexes plus pratiques pour l'industrie de récupération de liquide de gaz naturel.
