Abstract: Un acheminement par routage à la source efficient et scalable peut être effectué dans des réseaux multi-domaines par substitution d'identifiants de chemins pour des listes de sauts intra-domaines dans des listes de sauts de routage à la source. Les identifiants de chemins sont ensuite remplacés par les listes de sauts intra-domaines correspondantes au niveau des nuds d'extrémité d'entrée de chaque domaine correspondant. Les identifiants de chemins ne définissent pas de sauts individuels le long d'un segment de chemin intra-domaine et sont par conséquent généralement plus courts que les listes de sauts intra-domaines. Afin de faciliter les techniques d'acheminement par routage à la source dans des réseaux multi-domaines, des tables de routage dans les noeuds d'extrémité des domaines correspondants sont mises à jour pour associer les identifiants de chemins aux listes de sauts intra-domaines correspondantes lors d'un calcul de chemin inter-domaine (ou immédiatement après ce calcul) .

Abstract: A method of recovering purified partly-hydrolyzed cellulose particles from a composition comprising agglomerated partly-hydrolyzed cellulose particles and an acid, using electrodialysis. The invention addresses the problem of reducing the acid to very low levels while avoiding the high capital and operating costs, high water usage and large filtration surface area or dilution time requirements of the prior art processes. Following dilution, concentration by centrifuging or settling, and/or dialysis of the composition, the composition is treated in an electrodialysis cell to remove ions, such as free sulfate from sulfuric acid. The method may include having an anion exchange resin in the feed compartment of the electrodialysis cell, adding a base to the receiving solution in the electrodialysis cell, and a second step of electrodialysis of the purified partly-hydrolyzed cellulose particles.

Title: Steam foam methods for steam-assisted gravity drainage
Inventor: SANDERS AARON
IPC: E21B21/14
Filed: 2015-07-31
Granted: 2022-08-30
Abstract: Methods for making efficient use of steam in a steam-assisted gravity drainage (SAGD) process for recovering heavy oils from tar sands and similar petroleum deposits are disclosed. The methods utilize a surfactant to generate steam foam in ways that maximize efficient use of steam. In some aspects, steam foam is used in water layers or gas caps that reside above steam chambers to prevent steam loss from the chambers.  The predominant use of relatively dry steam in SAGD processes makes it challenging to find ways to introduce surfactants and generate steam foam. Decreasing the mobility of the steam by converting at least some of it to foam allows the wellbore and steam chambers above the injection site to be more fully developed, provides for more effective heat transfer to the heavy oil and rock, improves production, and allows recovery of the heavy oil with a minimum amount of steam usage.
