    摘要: Hydrocarbon liquid products are filtered and removed from a three phase hydrocarbon synthesis slurry comprising gas bubbles and particulate catalyst solids in a hydrocarbon liquid, by circulating the slurry through a gas disengaging downcomer immersed in the slurry to a filtration zone external or internal of the reactor, and then back into the slurry in the reactor. The gas disengagement densifies the slurry which is passed across the filtration surface under high flow conditions, to reduce solids build up on the filter as filter cake. Circulation through the filtration zone occurs by gravity and hydrostatics due to slurry density differences. The downcomer may also be a gas and solids reducing downcomer.

    摘要: A method and system for long-term flow assurance is provided. Data is periodically acquired from multiple transportation systems each having a transportation structure such as a pipeline, and a transported material such as hydrocarbons or oil and gas. The data is stored in a central location. A global predictive flow model is maintained based on the data acquired from the multiple transportation systems. A data set of a transportation system of the multiple transportation systems is analyzed via the global predictive flow model to determine a flow assurance issue of the transportation system.
