Investigation of hydrate formation and hydrate transportation with and without dispersant additives under multiphase flow conditions

摘要

Hydrates formation and hydrates transportation have been investigated for condensate and crude oil systems, with and without dispersant additives. Thests have been carried out in a multiplase pilot loop. Results obtained under different conditions (water cuts, flow regimes, ...) are presented. It is show that hydrate formation can depende on the fluid composition and the flow regime and that dispersant additives enable the flow to be maintained in the presence of hydrate. Phenomena observed during hydrate formation are also reported. This work has been carried out in the framework of JIP Eucharis.
