Test scenario
ECI used the following protocol to test the efficacy of Recover in a laboratory environment.
A sample of sludge was taken from a 350,000 BBL crude oil storage tank, with 12,000 BBLs of sludge in a firm (milkshake) consistency at the bottom of the tank.
Control sample
To the first beaker, a measured 200ml of the collected sludge, plus 400ml of crude oil from the same storage tank was added as diluting fluid.
This control sample was used to observe any solubilization (reduction) of the sludge just from contact with the crude
(without Recover).
Test sample
To the second, identical beaker, a measured 200ml of the collected sludge, plus 400ml of crude oil from the same storage tank was added as diluting fluid (same as the Control sample).
4ml of Recover was added to the Test sample.
Daily mixing for 4 days
Both the Control and Test samples were mixed twice daily for 30 seconds (once in the morning, once in the evening) over the first 4 days of the test.
