Abstract: A three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields is provided, which is applied to quick degassing of a gas-liquid two-phase flow. The three-stage tubular T-shaped degassing device adopts a quick degassing technology combining a microbubble uniform mixed rotational axial flow field and a spiral runner conical spiral flow field with layered jet collision reversing depth degassing. A microbubble uniform mixer is configured to adjust gas-liquid two-phase flow containing big bubbles into microbubble uniform mixed axial flow. A microbubble cyclone is configured to adjust the microbubble uniform mixed axial flow into multiple strands of rotational axial flows containing microbubbles. A rotational axial flow degasser implements the horizontal type microbubble uniform mixed multiple strands rotational axial flow degassing operation to remove most microbubbles to form axial flow gas and axial flow liquid.

Abstract: A method for preparing a class of highly stabilized and soil-dispersible nanoparticles and using the nanoparticles as a remediation technology for immobilizing toxic metals at toxic metal contaminated sites. The method employs a composition containing select polysaccharides (starch or cellulose) as a stabilizer for the nanoparticles in a liquid carrier, and results in suspensions of nanoparticles of desired size and mobility in water, soils or sediments. The stabilizer can facilitate controlling the dispersibility of the nanoparticles in the liquid carrier. An effective amount of the composition is delivered to a contaminated site so that the nanoparticles can immobilize one or more toxic metals of the contaminated site.
