The present disclosure relates to an apparatus for preparing an oligomer, including: a reactor receiving a monomer stream and performing an oligomerization reaction to prepare a reaction product; a product discharge line for transferring a reaction product stream discharged from the reactor; and a bubble catcher provided in any area of the product discharge line to remove bubbles contained in the reaction product stream.

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.

The present invention generally relates to systems and methods for the separation and removal of carbon dioxide from a liquid, for example, seawater. The systems include an extraction system that collects carbon dioxide from the seawater through a medium, and removes carbon dioxide from the medium; the extraction systems comprising a reactor and a membrane. Alternatively, the extraction system includes a reactor, a membrane and a catalyst.

A process for the reduction of flaring/venting gases during completions operations on an oil/gas well, said process comprising providing a well in need of completion; providing a system to capture oil and gas generated by the well; the system including a primary separator to separate an incoming well stream into a plurality of streams wherein a first stream is sent to a pipeline and a second stream is sent for further processing. The process further includes flowing and collecting a third stream of gas in a gas pressure vessel; compressing the collected gas in the vessel until parameters of compressed gas are compressed to provide a constant feed to the pipeline; and transferring the compressed gas to the gas pipeline wherein the process reduces the amount of gas flared and/or vented during operation by over 80%.

A multi-waste processing system includes a processing chamber. The processing chamber includes one or more heaters and a piston, and the processing chamber is configured to evaporate liquid waste and compact solid waste input. A condenser is operably connected to the processing chamber. The condenser is configured to condense water from the evaporated liquid waste output from the processing chamber. A gas and water separator is operably connected to the condenser. The gas and water separator is configured to separate water from the evaporated liquid waste output from the processing chamber. A recirculation pathway connects the gas and water separator to the processing chamber to recirculate gas from the gas and water separator to the processing chamber. The piston is actuated to keep the one or more heaters in close proximity to the solid waste and the liquid waste in the processing chamber.

A desalination system that can comprise an inlet, an optional preheating stage, multiple evaporation chambers and optional demisters, product condensers, a waste outlet, one or more product outlets, a nested configuration that facilitates heat transfer and recovery and a control system. The control system can permit operation of the purification system continuously with minimal user intervention or cleaning. The desalination system can operate with any number of pre-treatment methods for descaling, and with degassing systems to eliminate or reduce hydrocarbons and dissolved gases. The system is capable of removing, from a contaminated water sample, a plurality of contaminant types including microbiological contaminants, radiological contaminants, metals, and salts.

The present invention relates to vapour-solids separations, and in particular provides a process for the separation of a stream comprising vapour and a stream comprising solids from a stream comprising vapour and solids using a separation vessel, said separation vessel having: a. a first inlet for the stream to be separated, b. a liquid outlet, c. a vapour outlet, d. a demister located on the vapour outlet, and e. a second inlet by which liquid can be passed to the demister said process comprising (i) passing the stream comprising vapour and solids through the first inlet and in to the separation vessel, (ii) recovering from the vapour outlet a vapour stream which comprises vapour from the stream comprising vapour and solids and which vapour stream has passed through the demister in the separation vessel, (iii) passing to the separation vessel, via the second inlet, a first liquid stream which contacts the vapour stream in the demister, and (iv) recovering from the liquid outlet a second liquid stream which comprising the solids from the stream comprising vapour and solids, and liquid from the first liquid stream.

A system for the pyrolysis of a pyrolysis feedstock utilizes a pyrolysis reactor for producing pyrolysis products from the pyrolysis feedstock to be pyrolyzed. An eductor condenser unit in fluid communication with the pyrolysis reactor is used to condense pyrolysis gases. The eductor condenser unit has an eductor assembly having an eductor body that defines a first flow path with a venturi restriction disposed therein for receiving a pressurized coolant fluid and a second flow path for receiving pyrolysis gases from the pyrolysis reactor The second flow path intersects the first flow path so that the received pyrolysis gases are combined with the coolant fluid. The eductor body has a discharge to allow the combined coolant fluid and pyrolysis gases to be discharged together from the eductor. A mixing chamber in fluid communication with the discharge of the eductor to facilitates mixing of the combined coolant fluid and pyrolysis gases, wherein at least a portion of the pyrolysis gases are condensed within the mixing chamber.
