Inventor: LE ROY-DELAGE SYLVAINE
IPC: C04B28/00
Filed: 2004-05-14
Abstract: La présente invention a trait à un système de ciment auto-adaptatif comportant du ciment, de l'eau et au moins un additif qui réagit ou se dilate au contact du pétrole ou du gaz. On a identifié divers produits chimiques comprenant du caoutchouc alkylstyrène, du polynorbonène, des résines telles que des copolymères vinylacryliques et la terre à diatomées. Ces additifs ont pour effet de rendre le ciment autorégénérant dans le cas d'une défaillance physique ou d'endommagement tels que des déformations de type microanneaux. La propriété d'autorégénération est produite par le contact avec des fluides hydrocarbonés souterrains, le mécanisme de réparation potentiel est ainsi activé si ou quand c'est nécessaire dans le cas d'un début de perte d'isolement de zone. Dans un autre mode de réalisation, la dilatation est induite de manière délibérée par le pompage d'un fluide hydrocarboné dans le voisinage du ciment séché.

Title: Reactivation of lime-based sorbents by co2 shocking
Inventor: SALVADOR CARLOS
IPC: B01J20/04
Filed: 2003-11-14
Abstract: The present invention discloses a method and an apparatus for reactivating lime-based sorbents and increasing the carbon dioxide-capture capacity of the sorbent in the combustion of carbon-containing fuels. The method of the present invention seeks to increase the carbon dioxide capture capacity of lime-based sorbents by applying concentrated or 100% carbon dioxide directly to a lime-based sorbent. Optionally, the lime-based sorbent may be pretreated using a hydration process after each process of carbon dioxide separation. The regenerated sorbent is carbonated in a presence of concentrated carbon dioxide and elevated temperatures. The invention is useful in reducing the need to add additional sorbent to maintain the carbonation/calcination cycle. The regenerative potential of the sorbent as manifested by the present invention leads to increased carbon dioxide-capture capacity of the sorbent.
