Spill-SOS: Self-Pumping Siphon-Capillary Oil Recovery

“…As such, it presents a possibility to enable an automatic unattended approach for fluid transport, including oil transport. Previously, siphon-based devices have been proposed for various applications, such as irrigation and spillway. − However, few studies are reported on utilizing siphon action for oil recovery, not to mention the optimization and improvement of the siphon action for the oil recovery performance. Moreover, the previous siphon devices applied for fluid transport still suffer from two significant issues (Figure S1b), which deteriorate the performance in practical applications: (i) Poor stability and inability to self-restart.…”

Graphene petal foams with hierarchical micro- and nano-channels for ultrafast spontaneous and continuous oil recovery

“…Recently, the siphon effect, relying only on gravitational potential energy difference to continuously transport liquids, 11,12 has been utilized for various applications such as irrigation, oil recovery, and spillway. [13][14][15][16][17][18] As compared to conventional pump-assisted oil contamination cleanup methods, 19,20 siphon action may provide a spontaneous, continuous, low-cost, and green route with signicantly reduced costs. However, low oil transport rate due to many factors such as high viscosity of oil, and physical/chemical properties of channels restricts further development of siphon-assisted oil recovery.…”
