Bulgaria Solid Particle Type Temperature-Resistant Salt-Resistant Polyacrylamide for Petroleum Mining Wastewater Treatment

Jan 26, 2022 · Enhanced oil recovery (EOR) acquires global interest in the petroleum industry. Several technologies are implemented to retrieve the residual oil after conventional flooding treatment. One of these prospering technologies is the chemical EOR through polymeric nanocomposites flooding, where nanotechnology acquires incremental attention in the field of …

To navigate the front matter of this eBook by page number, you will need to use the volume number and the page number, separated by a hyphen. For example, to go to page v of volume 1, type “1-v” in the Go box at the bottom of the screen and click "Go." To go to page v of volume 2, type “2-v”… and so forth. Encyclopedia of Polymer ...

May 01, 2021 · Core-shell microspheres of graphitized carbon consisting of a solid carbonaceous core surrounded by a porous Cr-Ni-Fe shell are produced in ultra-high temperature ethane steam crackers. Considerable volumes of these microspheres are suspended in quench water and are directed to oceans while they have not been detected as pollutants so far.

all types of constructed wetlands for wastewater and runoff. It is to be used in conjunction with an accompanying volume that provides informa-tion specific to a particular type of wastewater or runoff. The other volumes in the series are Volume 2: Domestic Wastewater, Volume 3: Agricultural Wastewater, Volume 4: Coal Mine

Much interest is directed at the chemical structure of hydraulic fracturing (HF) additives in unconventional gas exploitation. To bridge the gap between existing alphabetical disclosures by function/CAS number and emerging scientific contributions on fate and toxicity, we review the structural properties which motivate HF applications, and which determine environmental fate …
