Although the technology for response to oil spill incidents is far more effective and efficient than in previous decades, there continues to be a need to develop technologies that improve clean-up processes whilst ensuring that they are less costly to both marine life and the economy 4. Oil spills continue to have catastrophic effects on marine ecosystems around the world today 1, 2, 3. These results suggest that the HPCS is a promising material for oil/water separation and recovery under challenging conditions. This is an effective and economical recovery system, removing the need for consistent solvent washing and drying processes. For five cycles of oil adsorption/mechanical compression the HPCS was able to provide water filtrate with oil concentrations of under 15 ppm. More importantly, the HPCS material could be reused via a simple mechanical compression process, and the uptake capacity was retained over ten cycles. The system was able to strip crude oil from water emulsions of 1000 ppm to a negligible level of 2 ppm oil with minimal amounts of the HPCS material. The high surface area, porosity, hydrophobicity, and selectivity of oil over water made the hyper-crosslinked polymer coated sponge (HPCS) an ideal sorbent for efficient oil/water separation. A commercial melamine formaldehyde sponge was coated with an optimised superhydrophobic/superoleophilic hyper-crosslinked polymer and applied to the removal of crude oil from oil-in-water emulsions for the improvement of oil spill clean-up processes. The graphic curve will be updated as well.Developing materials with high efficiency for recovering oil to mitigate the environmental impact of oil spills has always been a challenging task. All other values will be re-calculated automatically. Just put your values (either imperial or metrical) in the appropriate fields below and press ENTER. The use of any of the calculators’ results is at the user’s sole risk. ![]() The calculator below is for informative purposes only. You can calculate pre-filled values of oil classified by ISO 3448 with grades VG22, VG32, VG46 or VG68 (at viscosity Index = 100) or enter specific values for any other oils. ![]() These data is enough to determine kinematic viscosity at any other values of temperature and as well Viscosity Index. the Viscosity Index (VI) by the formulas specified in ASTM D2270 (`Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100☌ 1`) or in ISO 2909 (`Standard Practice for Calculating Viscosity Index from Kinematic Viscosity at 40 and 100☌ 1`) or in ГОСТ 25371-2018 (`Нефтепродукты.the kinematic viscosity values, depends from temperature, calculated by the formulas specified in ASTM D341 – (‘Standard Practice for Viscosity-Temperature Charts for Liquid Petroleum Products’).The interpolation calculator provided below is used to determine: ![]()
