Apparatuses to remove entrapped air and debris from bitumen are provided. The apparatuses include a tank comprising a first and second compartment with a separating surface therebetween. Bitumen froth can be received in the first compartment and can flow from the first compartment to the second compartment via the separating surface along a first portion of the flow path. The debris is separated from the bitumen in the first compartment and eliminated through a disposal aperture to form intermediate bitumen. The intermediate bitumen then travels along a second portion of the flow path to the second compartment where it is heated to allow entrapped air to escape and form processed bitumen, prior to exiting from the apparatus. The apparatus is particularly suitable for removing entrapped air and debris from bitumen mined from bituminous sands. Related processes for operating the apparatuses are also provided.

The acid gas removal system for removing acidic gases from gaseous hydrocarbons (10) removes sour gases, such as hydrogen sulfide (H.sub.2S) and carbon dioxide (CO.sub.2), from an input gaseous stream. The system (10) includes a contactor (12) for contacting the input gaseous stream with an absorption liquid solvent (ALS), and a stripper (24) for recycling the absorption liquid solvent (ALS) and removing acidic gases (AG) therefrom, but with the addition of a pair of plate-plate heat exchangers (22, 26). The first heat exchanger (22) heats the used absorption liquid solvent (UALS) output from the contactor (12) prior to injection into the stripper (24). The used absorption liquid solvent (UALS) is heated via heat exchange with the acidic gases (AG) output from the stripper (24). The second heat exchanger (26) cools the recycled absorption liquid solvent (RALS) before injection back into the contactor (12).

An apparatus for capturing CO.sub.2 from flue gas includes (a) an absorber, (b) a stripper, (c) a heat exchanger, (d) an amine absorbent circulating through the absorber, the stripper and the heat exchanger, (e) a water washing unit downstream from the flue gas outlet of the absorber, and (f) an electrochemical cell. The electrochemical cell is connected to the water washing unit and is adapted to adsorb and decompose nitrosamine compounds present in liquid separated by the water washing unit.

A method for revamping a CO2 removal section for removing carbon dioxide from a hydrogen-containing synthesis gas, wherein the CO2 removal section comprises an absorption section (2) wherein carbon dioxide is transferred to an absorbing solution and a stripping tower (3) for regeneration of the CO2-loaded solution, said stripping tower comprising an upper zone (4) where a first gaseous CO2 stream (10) and a partially regenerated semi-lean solution (11) are produced, and a lower zone (5) acting as a stripping zone where a second gaseous CO2 stream (12) and a lean regenerated solution are produced, the second CO2 stream (12) being a substantially pure stream containing less hydrogen and impurities than the first CO2 stream, and wherein the method of revamping provides the installation of sealing means (16) inside the stripping tower (3), arranged to isolate said second gaseous CO2 stream (12) from the first stream (10), so that the second stream (12) can be exported separately.

The present disclosure provides for a separations system for separating ethylene, 2-methylbutane and at least one unsubstituted (C6-C12) hydrocarbon in a multi-component condensate mixture. The separations system includes a feed conduit in fluid communication with a source of the multi-component condensate mixture, a stripper column in fluid communication with the feed conduit, where the stripper column separates the multi-component condensate mixture into a heavies component mixture with at least one unsubstituted (C6-C12) hydrocarbon, and a top mixture having a medium component (s) that include at least the 2-methylbutane and a light component (s) that include at least the ethylene. The separations system further includes a flash drum that separates the top mixture into the medium component (s) and the light component (s). The separations system does not include a distillation column disposed between the source of the multi-component condensate mixture and the flash drum.

An improved system for separating gas from a process stream by providing a stripping unit at the overhead stream of a fractionation column to selectively and effectively remove the gas using a stripping fluid without providing a dedicated light-ends separations unit. The stripper unit may be connected to the reflux drum at the overhead stream. The system for separating gas further achieves greater thermodynamic efficiency by means of a split column design using mechanical vapor recompression with the reboiler and condenser integrated in a falling-film evaporator- or thermosiphon-type vapo-condenser.

According to embodiment, a carbon dioxide capturing system cools a regenerator discharge gas discharged from a regenerator 5 containing carbon dioxide by a cooling unit 8, and then sends the gas to a cleaner 9. The cleaner 9 receives condensed water generated from the regenerator discharge gas cooled by the cooler 9, and a gaseous cooled regenerator discharge gas, and cleans the cooled regenerator discharge gas by a cleaning liquid. The cleaner 9 has a first liquid reservoir 9b configured to store the condensed water, and a second liquid reservoir 9c configured to store the cleaning liquid having cleaned the cooled regenerator discharge gas.

Method for removal of oxygen from seawater includes leading a stream of seawater and a pressurized stripping gas to a first mixer, mixing the seawater with stripping gas, leading the combined stream to a first gas/liquid inline separator, separating the stream into a liquid rich and a gas rich phase, leading the liquid stream and a stripping gas stream to a second mixer, mixing the liquid stream with the gas stream, leading the combined stream to a second stage inline separator, separating the combined stream into a liquid- and gas-rich phases, mixing the gas stream with a fresh water stream, leading this combined stream to a first stage scrubber, removing a portion of the salt entrained in the combined stream from the scrubber, and leading the salt depleted gas stream from the first scrubber via a heat exchanger or electrical preheater together with a fuel stream to a catalytic deoxidizer.

The present invention relates to an oil refining equipment comprising a stripping column with packing and the column has a height to diameter ratio from 0.1 to 10, from 0.5 to 5, from 1 to 4.9, from 1.4 to 4.5, from 1.6 to 2.8. It is used for degrading, decomposing or breaking down oxidation products of triglycerides, diglycerides, monoglycerides and/or fatty acids. A process for refining edible oils is described as well.
