  • Patent number: 9889401
    Abstract: An apparatus and method for flow management and CO2-recovery from a CO2 containing hydrocarbon flow stream, such as a post CO2-stimulation flowback stream. The apparatus including a flow control zone, a gas separation zone, a pretreatment zone, and a CO2-capture zone. The CO2-capture zone is in fluid communication with the pretreatment zone to provide CO2-capture from a pretreated flowback gas stream and output a captured CO2-flow stream. The CO2-capture zone includes a flow splitter to direct a first portion of the pretreated flowback gas stream to a CO2-enricher to provide an enriched CO2-stream for mixing with a second portion of the pretreated flowback gas to form a mixed stream. The CO2-capture zone further includes at least one condenser to output the captured CO2-flow stream.

  • Patent number: 9694309
    Abstract: This disclosure teaches a composition and process which makes it possible to remove floating particulates or prevent the dissemination or particulates, by the misting of a solution that readily captures any particulate material in the air. More specifically, the present disclosure teaches the composition and use of aromatic compounds that are semi-volatile organic compounds (SVOCs) or slow evaporators in water-based carriers with surfactants as the misting/fogging agent for dust suppression. The particulate material is lowered to surfaces and removed by vacuuming, damp-wiping or using a dry cloth with a cationic charge (static cloth). This method can be achieved with neutral air pressure differentials in the work areas.

    Abstract: The invention relates to a process for separating off solid particles, in particular coke particles, from a water phase by means of gravity in a plant for generating hydrocarbons by cracking a hydrocarbonaceous feed, and also to a device for carrying out the process. In contrast to the prior art, the water phase is taken off predominantly from a point above the column bottom B via the outlet A. The first gravity separator 2 which is constructed as a multistage settling tank 2 is situated not beneath, but next to, the scrubbing water column 1. The bottom phase of the scrubbing water column 1 already acts as a part of the first gravity separator 2. Thus, via the outlet 5 in the column bottom B, a heavy water phase which is loaded with coke particles is already taken off and passed into the second gravity separator 3. This heavy water phase is further treated, together with the heavy water phase which is loaded with coke particles from the recesses 6 of the multistage settling tank 2.

  • Patent number: 8647413
    Abstract: A method for recovering carbon dioxide (CO2) from a gas stream is disclosed. The method includes the step of reacting CO2 in the gas stream with fine droplets of a liquid absorbent, so as to form a solid material in which the CO2 is bound. The solid material is then transported to a desorption site, where it is heated, to release substantially pure CO2 gas. The CO2 gas can then be collected and used or transported in any desired way. A related apparatus for recovering carbon dioxide (CO2) from a gas stream is also described herein.

  • Patent number: 8597433
    Abstract: A pickling process for descaling metal includes a two-stage filtering process to remove pickling liquor fog, mist, and/or vapors from a gas collected during the descaling process. The process includes a two-stage filtering arrangement that includes a first stage filter, which is arranged to remove a liquid phase of the pickling liquor from the gas, and a second stage filter, which is arranged to remove a gaseous phase of the pickling liquor the said gas. The recovered pickling liquor can advantageously be recycled for reuse because it is recovered in a relatively higher concentration that has heretofore been possible.

  • Patent number: 8580022
    Abstract: The portable air purification device provides extreme portability such that the device can be placed virtually anywhere desired. Should an area need the device, one person can easily transport as needed. Also important is the separability of the vacuum canister and filtration canister. Often it may be advantageous to place the vacuum canister strategically, and the filtration canister supplying purified air in another location. The device provides for such via the separate canisters and the transfer hose, which can be almost any length needed. The device uses liquid filtration media, solid filtration media, and a HEPA filter.

  • Patent number: 8574406
    Abstract: A fermentation liquid feed including water and a product alcohol and optionally CO2 is at least partially vaporized such that a vapor stream is produced. The vapor stream is contacted with an absorption liquid under suitable conditions wherein an amount of the product alcohol is absorbed. The portion of the vapor stream that is absorbed can include an amount of each of the water, the product alcohol and optionally the CO2. The temperature at the onset of the absorption of the vapor stream into the absorption liquid can be greater than the temperature at the onset of condensation of the vapor stream in the absence of the absorption liquid. The product alcohol can be separated from the absorption liquid whereby the absorption liquid is regenerated. The absorption liquid can include a water soluble organic molecule such as an amine.
