  • Publication number: 20240093101
    Abstract: Methods of crude oil stabilization may include separating crude oil in a bulk separator into a first light hydrocarbon stream, a first water stream, and a first bottoms stream; separating the first bottoms stream in an intermediate pressure separator into a second light hydrocarbon stream, a second water stream, and a second bottoms stream; separating the second bottoms stream in a separator into a third light hydrocarbon stream, a third water stream, and a third bottoms stream; introducing a stripping gas stream comprising methane into the separator; storing the third bottoms stream in a vessel comprising an outlet for a fourth light hydrocarbon stream; treating at least a portion of the first, second, third, and fourth light hydrocarbon streams in a vapor treatment process to form a final light hydrocarbon stream; and recycling at least a portion of the final light hydrocarbon stream to the separator.

  • Patent number: 10130897
    Abstract: A co-current contacting system is described herein. The co-current contacting system includes a co-current contactor located in-line within a pipe. The co-current contactor includes an annular support ring configured to maintain the co-current contactor within the pipe and a number of radial blades configured to allow a liquid stream to flow into the co-current contactor. The co-current contacts also includes a central gas entry cone configured to allow a gas stream to flow through a hollow section within the co-current contactor, wherein the co-current contactor provides for efficient incorporation of liquid droplets formed from the liquid stream into the gas stream. The co-current contacting system also includes a separation system configured to remove the liquid droplets from the gas stream.

  • Patent number: 9919237
    Abstract: Systems and methods are provided for reducing maldistribution of liquids and vapors in packed towers. An exemplary separation system includes a separation tower including at least two packed beds, and a vapor redistribution plate disposed between two sequentially disposed packed beds, wherein the vapor redistribution plate is configured to mix a vapor from a lower packed bed before introducing the vapor into an upper packed bed.

  • Patent number: 8899557
    Abstract: Provided are gas processing facilities for the separation of components in a gas stream and methods of using the same. The facility includes one or more co-current contactors. Each contactor includes a mass transfer vessel having a mixing section. The mixing section receives a gas stream and a liquid contacting stream. The mixing section mixes theses two streams and releases a two-phase flow. Each contactor also includes a separator that receives the two-phase fluid stream from the mass transfer vessel in-line, and then separates a vapor phase from a liquid phase. The separator has a gas-phase outlet configured to release the vapor phase as a treated gas stream, and a liquid-phase outlet configured to release the liquid phase as a loaded treating solution. The contactors may be used to remove water or other contaminant from a natural gas stream or other gas stream.

  • Publication number: 20110168019
    Abstract: A gas processing facility for the separation of fluids is provided. The facility includes co-current contactors placed in series. Each co-current contactor receives a gas stream that includes a non-absorbing gas such as a hydrocarbon gas or nitrogen. The gas stream also includes an acid gas or other contaminant. Each co-current contactor also receives a liquid solvent stream. The co-current contactors then each release a sweetened gas stream and a gas-treating solution. In one processing direction, the contactors are arranged to deliver progressively sweetened gas streams. In the opposite processing direction, the contactors are arranged to deliver progressively richer gas-treating solutions. In one aspect, the facility includes at least a first co-current contactor, a second co-current contactor and a final co-current contactor. However, any number of at least two co-current separators may be employed. Methods and processes for separating a gas stream are also provided.
