METHOD AND DEVICE FOR FORMATION AND TRANSPORTATION OF GAS HYDRATES IN HYDROCARBON GAS AND/OR CONDENSATE PIPELINES.

摘要

The present invention relates to a method and system for treatment of a flow of fluid hydrocarbons containing water. The flow of hydrocarbons is introduced into a mixer (7) where it is mixed with liquid carbon dioxide (6) before the resulting mixture is cooled in a cooler (8) and conveyed to a reactor (9), in which all water present in the hydrocarbon flow will be in the form of hydrates, and said flow is conveyed to a pipeline (11) to be transported to its destination. The cooling system may comprise a choke or a mixer where the warm hydrocarbon flow is mixed with a cold flow of hydrocarbons.
