Patent number: 5302210Abstract: A rapid deployment system for recovering oil from beachers includes an articulated vehicle for propelling and suspending a vacuum head above a beach or the like. A selected area of the beach is irrigated with sufficient quantities of water to saturate the selected area. Oil deposited on the beach is driven to the surface. A sufficient quantity and velocity of air moves over the surface beneath the vacuum head to develop a water column upon which resides a frothy foam mixture of air, water and oil which is drawn into the head. In the vacuum head, the velocity of the air flow is suddenly and significantly reduced above a fluid sump wherein entrained oil and water droplets fall into a sump for processing outside of the vacuum head. A metal auger can be provided within the vacuum head to pump oil from pools and separate entrained oil droplets from the high velocity air flow. A special terrain vehicle which propels and supports the vacuum head is modular and can be transported by helicopter with the entire system.Type: GrantFiled: April 7, 1992Date of Patent: April 12, 1994Assignee: Fraser Environmental Systems, Inc.Inventor: Gary R.

Water/surfactant process for recovering hydrocarbons from soil in the absence of emulsifying the oil
Patent number: 5252138Abstract: A water/surfactant process for removing oil from a soil that has been contaminated by an oil spill.
