Devices and methods for quickly removing unwanted water from tanks

The present invention includes iterations of devices for absorbing water and hydrocarbons that accumulate in hydrocarbon handling and dispensing systems, fuel tanks, sumps, and other oil and hydrocarbon storage tanks, at gas stations and other locations such as ports, commercial trucking facilities, government installations, military bases, privately owned and commercial shipping vessels, and privately maintained fueling locations including trucking facilities, etc. Specialized versions of the devices can also clean up petroleum slicks on water surfaces-known as "sheen" or petroleum-contaminated water (PCW"), and other contaminants. The present invention can stop "phase separation". Once they have absorbed water, most versions of the device can also be disposed of easily and economically compared to alternative disposal methods due to their extremely light weight and because they can be dehydrated before disposal.
