Abstract
A floatable liquid hydrocarbon skimmer system for monitoring possible leaks in hazardous liquid tanks incorporates a vertically disposed tubular housing having an upper end with passages to admit liquid and provides a lower collection chamber for recovered hydrocarbon liquid. The housing has a hydrocarbon liquid-water separator associated with the chamber which has a capillarial filter which will pass only the hydrocarbon liquid through to the collection housing, while being impervious to the passage of water. A wick is in contact with the filter to draw the hydrocarbon liquid to the filter, and a valved outlet passage associated with the collection chamber permits emptying of the collected hydrocarbon liquid back to the tank.
