The present invention relates to a tubular oil separator providing separation of respective fluid components mixed in fluids from oil wells, wherein the tubular oil separator A is arranged to mitigate problems related to turbulence and possible non-Newtonian fluid behaviors of fluid components mixed in the fluids from the oil wells in the oil separator. The invention further relates to a method of operating a separator. Moreover the invention relates to a system of multiple separators. Inventive aspects of the separator comprises an elongated outer, closed tubular section and an elongated, inner tubular section, which is closed in one end and open in another end, —where the inner tubular section is arranged inside the outer tubular section, —and where oil well substances are introduced into the open end of the inner tubular section via a tube feed section passing through the outer tubular section and into the inner tubular section, —and where the inner tubular section comprises multiple, elongated and parallel slots arranged in a longitudinal direction of the inner tubular section in a circumferential manner, —where the inclination of the separator facilitates separation of the oil well substances into lower density substances and higher density substances, —where the lower density substances by buoyancy drift upward through the slots and exit via an upper outlet in the outer tubular section and higher density substances sink downward through the slots and by gravitation exit via a lower outlet in the outer tubular section.

The present disclosure relates to an apparatus for gravity separation, which comprises a plurality of gravity separation modules. Each of the gravity separation modules comprises an inlet, a first outlet, a first conduit connecting the inlet and the first outlet, a second outlet located vertically different from the first outlet, a second conduit in communication with the second outlet, and a plurality of third conduits connecting the first conduits and the second conduits. The present disclosure also relates to a corresponding method for gravity separation.

A separator for an oil well produced fluid comprises a housing and a tube group arranged within the housing. The tube group includes a plurality of horizontal pipes in a layered arrangement along a vertical direction, and a plurality of vertical pipes which allows adjacent layers of the horizontal pipes to be in fluid communication with each other. The plurality of horizontal pipes shares an inlet pipe in communication with the outside of the housing, and each of the horizontal pipes has a respective outlet. The separator is configured in such a manner that the horizontal pipes in an upper layer, a middle layer, and a lower layer are respectively used as oil pipes, water pipes, and sediment pipes.

The current application is related to a process for separating volatile compounds from a reaction mixture comprising a polymer and said volatile compounds, comprising the steps of passing the reaction mixture through the inlet into the gravimetric vessel of the gravimetric separator of a separating device according to the present invention, withdrawing a first polymer-rich stream comprising mainly polymer through the first outlet of the gravimetric vessel, withdrawing a first polymer-lean stream comprising mainly volatile compounds through the second outlet of the gravimetric vessel, passing at least a part of the polymer-lean stream as a second polymer-lean stream through the first inlet into the flash vessel of the flash separator of the separating device according to the present invention, withdrawing a liquid stream through the first outlet of the flash vessel, and withdrawing a gaseous stream through the second outlet of the flash vessel.

A solvent extraction method for hydrometallurgical liquid-liquid extraction processes, in which method solution phases are separated from a dispersion while the dispersion flows horizontally in a settler from a feed end to a discharge end. The mass flow of the dispersion and solution phases is divided into a plurality of parallel and mutually separated plug flows flowing in the settler from the feed end to the discharge end. The settler (1) comprises a plurality of elongated settler sections (4) which are mutually separated and side by side in parallel to each other, Inc settler sections (4) extending from the feed end (2) to the discharge end (3), forming a plurality of mutually separated parallel plug flow channels.
