摘要： A method of blending delayed coker feedstocks to produce a coke that is easier to remove from a coker drum. A first feedstock is selected having less than about 250 wppm dispersed metals content and greater than about 5.24 API gravity. A second delayed coker feedstock is blended with said first resid feedstock so that the total dispersed metals content of the blend will be greater than about 250 wppm and the API gravity will be less than about 5.24.

摘要： A method of transporting a mixed phase fluid in a conduit. A hydrate and/or wax film is permitted to deposit on an inner wall of the conduit in a conversion zone, the conversion zone being less than a length of the conduit. A quantity of heat is applied to the conduit in the conversion zone until the hydrate and/or wax deposited on the inner wall in the conversion zone separates therefrom, thereby inhibiting the continual formation of hydrates and/or wax on the inner wall. The separated hydrates and/or wax are flowed in the mixed phase fluid.

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.

摘要： A system for removing acid gases from a raw gas stream the system includes a cryogenic distillation tower. The tower receives and separates the raw gas stream into an overhead methane stream and a bottom liquefied acid gas stream. Refrigeration equipment downstream of the cryogenic distillation tower cools the overhead methane stream and returns a portion of the overhead methane stream to the cryogenic distillation tower as liquid reflux. The system also may include a first molecular sieve bed upstream of the distillation tower and a second molecular sieve bed downstream of the distillation tower. The first molecular sieve bed adsorbs water while the second molecular sieve bed adsorbs additional acid gases from the cooled overhead methane stream.
