Abstract
A technique is provided for producing a slurry of solid particulates and hydrocarbon production fluid for transport via a subsea flow line. The technique utilizes a cold flow system that cools production fluid to a temperature below the temperature at which hydrates and other substances precipitate from the production fluid and form solid particulates. An instrumentation and control system is used to receive and process data from sensors in the system. The instrumentation and control system then provides control signals to one or more components of the cold flow system to produce a slurry having solid particulates with desirable characteristics. In addition, a cooling gas may be used to facilitate sub-cooling of the production fluid. The cooling gas is compressed and cools the production fluid as the gas expands via Joule-Thompson expansion. Furthermore, a discharge pressure controller may be used to control flow through the cold flow system.
