Title (EN) REGENERATION OF ACID GAS-CONTAINING TREATMENT FLUIDS
(FR) REGENERATION DE FLUIDES DE TRAITEMENT CONTENANT DES GAZ ACIDES
Abstract: front page image
(EN)An improved acid gas regeneration and injection process wherein the separated acid gas stream emerging from a regenerator is compressed and injected into subsurface reservoir, the improvement comprising conducting the acid gas separation in the regenerator under pressure that exceeds 50 psia and does not exceed 300 psia.
(FR)L'invention concerne un processus d'injection et de régénération de gaz acide, ledit flux gazeux acide séparé émergeant d'un régénérateur étant comprimé et injecté dans un réservoir de sous-surface. L'amélioration comprend la mise en place de la séparation du gaz acide dans la régénérateur sous pression qui dépasse 50 psia et ne dépasse pas 300 psia.
