Title (EN) GAS-TIGHT CENTRIFUGE FOR VOC SEPARATION
(FR) CENTRIFUGEUSE ÉTANCHE AUX GAZ DESTINÉ À SÉPARER COMPOSÉS ORGANIQUES VOLATILS
Abstract:
(EN) Gas-tight decanter centrifuge process for separation of volatile organic compounds from drilling fluid. A method is described for removing low gravity solids from a mixture of recovered oil based drilling fluid and low gravity solids and diluent. A gas-tight decanter centrifuge that is designed and constructed for this purpose in a gas-tight manor so to ensure vapour cannot escape the decanting process, and foreign oxygen cannot enter the process under normal operating conditions.
(FR) L'invention concerne un procédé centrifuge de décantation étanche aux gaz destiné à séparer des composés organiques volatils d'un fluide de forage. L'invention concerne un procédé destiné à éliminer des solides de faible gravité d'un mélange de fluide de forage à base d'huile récupéré et de solides de faible gravité et d'un diluant. Une centrifugeuse de décantation étanche aux gaz est conçue et est construite à cet effet de sorte à être étanche aux gaz, afin de s'assurer que des vapeurs ne peuvent pas s'échapper du procédé de décantation, et que de l'oxygène étranger ne peut pas entrer dans le processus dans les conditions de fonctionnement normales.
