Abstract

L'invention concerne des procédés permettant d'éliminer les mercaptans de flux d'hydrocarbures, par exemple, du pétrole brut ou du gaz naturel. Ces procédés utilisent des sels métalliques basiques qui réagissent avec les mercaptans de façon à former des mercaptides. Lesdits sels métalliques sont dissous ou en suspension dans des liquides ioniques qui virtuellement ne possèdent pas de pression de vapeur. Une fois que les mercaptides sont adsorbés dans lesdits liquides ioniques, le flux d'hydrocarbures démercaptanisés peut être éliminé, par exemple, par distillation, décantation, ou séparation par gravité. Puis les mercaptides peuvent être oxydés, par exemple, par exposition à l'air afin de former des disulfides. Ces disulfides sont insolubles dans les liquides ioniques, et peuvent donc facilement être éliminés. L'hydroxyde de sodium est le sel préféré, et les liquides ioniques non réactifs à l'eau sont les liquides préférés. Le flux d'hydrocarbures contenant des mercaptans peut être en phase gazeuse ou en phase liquide. L'écoulement du flux d'hydrocarbures sur/à travers le liquide ionique peut, par exemple, s'effectuer dans le sens du courant, à contre-courant, ou par étapes dans des réservoirs avec agitation mécanique, l'écoulement à contre courant étant l'écoulement préféré.
