Title (EN) COMPOSITION FOR CONTROLLING CLATHRATE HYDRATES AND A METHOD FOR CONTROLLING CLATHRATE HYDRATE FORMATION
(FR) DISPOSITIF PERMETTANT DE DEPOSER DES TUYAUX, DES CABLES, ETC., DANS DES FOSSES
Abstract:
(EN) Composition for controlling the formation, growth and/or agglomeration of clathrate hydrates, which comprises a Polymer A containing the repeating structural unit (1), wherein P1 is an atom on a macromolecular main chain; A1 is a direct bond or a spacer group, and R1 and R2 are selected from hydrogen; C1-6 alkyl; C3-7 cycloalkyl; C1-5 alkanoyl; or R1 and R2 together with the nitrogen atom to which they are attached form a C3-7 cyclic group, and having the number average molecular weight in the range from 400 to 7000 and having a cloud point greater than 50 °C for 1 wt.% solution in distilled water.
(FR) Elément permettant de déposer des tuyaux, des câbles ou des dispositifs similaires dans des fossés et des cavités creusés dans le sol, avant de les remplir avec du matériau de remplissage, et/ou de poser les fondations de murs en briques ou d'autres structures immergées. En utilisation, on place l'élément près du tuyau ou similaire durant la pose. L'élément comprend un manchon rempli d'un matériau de remplissage possédant des caractéristiques d'isolation. Le manchon est un sac allongé (20) fermé étanche, qui est rempli d'un matériau poudreux, fibreux ou granulaire, et qui en position non dépliée a la forme d'un coussin ou d'une couverture.
