A system and method for removing organic carboxylates from a mono ethylene glycol ('MEG') stream includes a reaction vessel; means for cooling and diluting the MEG stream being routed to the reaction vessel; means for acidifying the cooled and diluted MEG stream during its residence time within the reaction vessel; and means for removing an acetic-rich overhead stream from the reaction vessel. The acidification of the cooled and diluted MEG stream occurs under a vacuum. The reaction vessel may be located downstream of a calcium removal vessel and receive a filtered bottom stream from that vessel, or it may be a single reaction vessel that cycles between a calcium removal mode and an acetate removal mode, with the pressure of the single vessel being greater during the calcium removal mode than during the acetate removal mode.

System and process for removal of organic carboxylates from mono ethylene glycol (MEG) water streams by acidification and vaporization under vacuum

A MEG recovery process is described, in which a MEG stream is processed by performing a divalent treatment to reduce dissolved divalent cations in the portion of the stream; performing a sulfate treatment to reduce dissolved sulfate ions in the stream, the sulfate treatment comprising adding an underdose of one or more calcium halides, one or more lower calcium carboxylates, or a mixture thereof to a treatment stream; and precipitating calcium sulfate from the treatment stream; performing a solids removal treatment to reduce solids in the stream; and returning the treated stream, depleted in divalent cations, sulfate ions, and solids, to the MEG recovery process.

Removal of sulfate from meg streams using calcium chloride

Monoethylene glycol (MEG) may be reclaimed by a process that includes contacting a MEG-water-salt stream with a heat transfer fluid and then flash separating the MEG and water in the flash separator vessel where the pressure is higher than 0.3 barA (0.03 MPa), the temperature is in the range of above 120&#xb0; C. to about 250&#xb0; C., and the residence time of the MEG and water ranges from about 1 second to about 10 minutes, and then removing the MEG and water in an overhead of the flash separator vessel and removing the salt from the flash separator vessel. In some embodiments it is expected that the temperature of the process may range from above 165&#xb0; C. to about 250&#xb0; C. and/or that the pressure may be atmospheric.

Short contact, elevated temperature MEG reclamation

A system and method to vaporize a process or feed water stream does so in a liquid pool zone of a vessel as the stream comes into contact with a heating medium that is less volatile than the process stream. To keep the pool hot, the heating medium can be recirculated through a heater of a pump-around loop or a heater can be placed in the liquid pool. As the process stream is vaporized, any solids present in the process stream come out of the process stream and move into the heating medium. These solids may be further removed from the heating medium in the pool or in the pump-around loop. The vaporized process stream can be further condensed. Any heat recovered can be used to pre-heat the process stream or used in the pump around loop's heater in case of mechanical vapor recovery.

System and method to vaporize a process stream by mixing the stream with a heating medium

A system and process for the removal of divalent ions from a MEG-water stream are presented. The system includes a chemical treatment tank that receives the MEG-water stream, means for precipitating the calcium, magnesium, and hydroxide ions that are contained in the MEG-water stream, means for discharging the MEG-water stream from the chemical treatment tank, and means for recycling the discharged MEG-water stream back to the chemical treatment tank or routing it to a solids removal system. The means for precipitating the calcium, magnesium, and sulfate ions may be employed simultaneously or sequentially.

System and process for removal of organic carboxylates from mono ethylene glycol (MEG) water streams by acidification and vaporation under vacuum

A MEG stream having a first pH level is contacted with a CO-rich gas stream to yield a MEG product having a second different and lower pH level. The system and method can be readily incorporated into a slipstream MEG recovery package, with a source of the MEG stream being a MEG regeneration section of the package. The CO-rich gas could be a vented COstream from the MEG reclamation section of the package. Unlike hydrochloric and acetic acid overdosing, COoverdosing of the lean MEG stream does not lead to rapid acidification of the MEG product to be stored or injected.

System and method for pH control of lean MEG product from MEG regeneration and reclamation packages

A lean MEG stream having a first pH level is contacted with a CO-rich gas stream to yield a lean MEG product having a second different and lower pH level preferably in a range of 6.5 to 7.0. The system and method can be readily incorporated into a slipstream MEG recovery package, with a source of the lean MEG stream being a MEG regeneration section of the package. The CO-rich gas could be a vented COstream from the MEG reclamation section of the package. Unlike hydrochloric and acetic acid overdosing, COoverdosing of the lean MEG stream does not lead to rapid acidification of the lean MEG product to be stored or injected.

Process for the production of olefins

A process for the production of an olefin from a hydrocarbon by autothermal cracking, which process comprises: partially combusting the hydrocarbon and an oxygen-containing gas in the presence of a catalyst, wherein the stoichiometric ratio of hydrocarbon to oxygen is 5 to 16 times the stoichiometric ratio of hydrocarbon to oxygen required for complete combustion of the hydrocarbon to carbon dioxide and water, characterised in that the catalyst comprises palladium and at least one further metal being a Group IIIA, Group IVA, VA, a transition metal or a lanthanide.
