Abstract

Embodiments of the invention include a filtration system with a separation system including a primary process vessel with a main body enclosing an internal volume, and a removable end cap coupled to one of the ends of the main body. The primary process vessel includes fluid apertures enabling a fluid stream to enter or exit the inner volume. The separation system includes a filter support positioned in the inner volume, and a filter assembly coupled to the filter support. In some embodiments, the filtration system further includes a support frame, and the separation system is mounted on the support frame. In some embodiments, the separation system is fluidly coupled to another separation system. In some embodiments, the filter assembly includes a coalescing filter. In some further embodiments, the filter assembly includes a filter configured and arranged to filter hydrocarbons.

Dependent claims

A filtration system comprising at least one separation system, the separation system comprising:

a primary process vessel comprising a main body including first and second ends, the main body enclosing an internal volume;
at least one removable end cap coupled to at least one of the ends of the main body;
a first filter support and a second filter support positioned in the internal volume, the first filter support and the second filter support enclosing an interior volume positioned between the first filter support and the second filter support in the internal volume of the main body;
a first filter assembly coupled to the first filter support and a second filter assembly coupled to the second filter support, the first filter assembly and the second filter assembly arranged to place the internal volume in fluid communication with the interior volume;
at least one fluid inlet port arranged to enable one or more liquid emulsion stream having a continuous liquid phase and a discontinuous liquid phase to enter the internal volume of primary process vessel and contact the first filter assembly and the second filter assembly to generate a treated liquid stream where at least a portion of the continuous liquid phase is separated from the discontinuous liquid phase;
a first product fluid outlet port, wherein the first product fluid-outlet port is in a top portion of the primary process vessel and arranged to enable a first portion of the continuous liquid phase in the treated liquid stream to exit the primary process vessel;
a second product fluid outlet port, wherein the second product fluid outlet port is in a bottom portion of the primary process vessel and arranged to enable a first portion of the discontinuous liquid phase in treated liquid stream to exit the primary process vessel, and wherein the first product fluid outlet port and the second product fluid outlet port are arranged opposite each other on the first end of the primary process vessel;
a third product fluid outlet port, wherein the third product fluid outlet port is in the top portion of the primary process vessel and arranged to enable a second portion of the continuous liquid phase to exit the primary process vessel;
and
a fourth product fluid outlet port, wherein the fourth product fluid outlet port is in a bottom portion of the primary process vessel and arranged to enable a second portion of the discontinuous liquid phase to exit the primary process vessel, and wherein the third product fluid outlet port and the fourth product fluid outlet port are arranged opposite each other on the second end of the primary process vessel.
