Title (EN) REMOVING ELEMENTAL SULFUR FROM HIGH TEMPERATURE,HIGH PRESSURE WELLS
(FR) EXTRACTION DU SOUFRE ELEMENTAIRE DE PUITS A TEMPERATURE ELEVEE A HAUTE PRESSION
Abstract: front page image
(EN)A relatively nonvolatile, high molecular weight sulfur solvent produced by activating a dialkyl disulfide oil by the addition of a relatively high molecular weight predominantly aliphatic amine (e.g., a N-alkyl-1,3-propane diamine) and optionally further increasing the molecular weight by the addition of elemental sulfur. Such a sulfur solvent is particularly useful in sustaining a liquid phase at bottomhole conditions for high temperature, high pressure sour gas.
(FR)Un solvant du soufre, relativement non volatile de poids moleculaire eleve est produit par activation d"une huile de bisulfure de dialkyle par addition d"une amine essentiellement aliphatique de poids moleculaire relativement eleve (p. ex. la diamine N-alkyle-1,3-propane) et eventuellement par augmentation supplementaire du poids moleculaire par addition de soufre elementaire. Un tel solvant du soufre est particulierement utile pour maintenir une phase liquide au fond d"un trou ou regnent des conditions inherentes a un gaz acide a temperature et a pression elevees.
