摘要： The quick response system and method for removing volatile compounds from contaminated water disclosed herein may comprise, at least, a preconditioning stage, a stripping stage, a condenser stage, a refrigeration stage, and a scrubber stage. The present invention relates to a portable system and method that can be deployed on an emergency or quick response basis to purify aqueous streams containing volatile organic compounds (VOC) and chlorinated hydrocarbons, collectively volatile compounds (VC), emitted from petroleum and chemical processing facilities. The system allows manufacturing facilities having internal cleanup issues to become compliant with environmental standards and guidelines quickly. Once the issue in the petroleum facility are fixed, this method can be demobilized and removed from the site in a short period of time.

摘要： Embodiments of the present invention are generally related to a system and method to remove hydrogen sulfide from sour water and sour oil. Particularly, hydrogen sulfide is removed from sour water and sour oil without the need for special chemicals, such as catalyst chemicals, scavenger chemicals, hydrocarbon sources, or a large-scale facility. The system and method in the present invention is particularly useful in exploratory oil and gas fields, where large facilities to remove hydrogen sulfide may be inaccessible. The present invention addresses the need for safe and cost-effective transport of the deadly neurotoxin. Particular embodiments involve a system and method that can be executed both on a small and large scale to sweeten sour water and sour oil.

摘要： A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. Fresh liquid to be concentrated is also introduced into the re-circulating circuit at a rate sufficient to offset the amount of liquid evaporated in the flow corridor.

摘要： Disclosed is a reverse flow multi-stage sedimentation rake-free thickening device relating to the field of slime water treatment. The device includes a feed assembly, a guide assembly, and a clean coal collection assembly. The guide assembly also includes a central tank body and coal slurry flows from the upper part of the central tank body to the inner side wall of the central tank body through the feed assembly and the medicament, and then flows to the middle of the central tank body through the guide assembly. After the reaction, the bubbles carry the fine coal slime and move up to the clean coal collection assembly. The clean coal collection assembly is located above the outlet of the guide assembly, and the clean coal collection assembly is sequentially provided with a central collection area, a defoaming area, and a diversion settlement area from the middle to the outside.

摘要： Described herein are methods for transporting and/or harvesting gas from bubbles, as well as associated articles and systems. In some embodiments, transporting and/or harvesting the gas from the bubbles can reduce or prevent the amount of foam that is present within a system. According to certain embodiments, a conduit comprising a porous wall portion can be at least partially submerged into a foam and/or a bubble-containing liquid. The porous wall portion of the conduit can be configured and/or arranged, according to certain embodiments, such that the porous wall portion provides a fluidic pathway through which gas from the bubbles within the liquid may be channeled to a gaseous environment in the interior portion of the conduit. The gas may be transported, according to certain embodiments, along the interior portion of the conduit into an external gaseous environment and/or harvested from the interior portion of the conduit.

摘要： A water container with an ozone diffuser is an apparatus that is used to diffuse ozone gas into water that is either flowing through the apparatus or is retained by the apparatus. The apparatus includes an aeration chamber, an ozone generator coupler, a distribution hub, a plurality of porous tubes, and a degassing unit. The ozone generator coupler allows the apparatus to connect with a pressurized supply of ozone gas. The aeration chamber is used to retain the water that is currently being aerated by the ozone gas. The distribution hub receives the ozone gas from the ozone generator coupler and distributes the ozone gas amongst the porous tubes. The ozone gas is then evenly inserted from the porous tubes into the water retained by the aeration chamber. The degassing unit is used to neutralize the excess ozone before exhausting the excess ozone into the apparatus's surroundings.

摘要： A gas dissolving system using double mixers to generate a higher gas concentration in liquid is disclosed. The gas dissolving system includes two gas mixers, a degassing device, pressure valves, a pressure sensor, and a pump. Liquid flows through mixers to entrain gas therein, and it thus contains dissolved gas and undissolved gas. The liquid subsequently flows into the degassing device so that undissolved gas is released to the outside environment, and dissolved gas remains in the liquid. The liquid with dissolved gas combines with raw liquid and is diluted so that it becomes liquid with a desired gas concentration as the output. A high gas concentration of liquid is obtained after more cycles of fluid flow through the mixers to dissolve gas without combining raw liquid.
