Selection criteria and laboratory evaluation of oil spill sorbents.: En46-4/76-5E-PDF

"Twenty different types of oil spill sorbents were studied in terms of desirable performance and operational criteria. Initially, a preliminary laboratory evaluation of the oil pick-up capacity of several oil sorbents was performed using a Canadian western crude oil. Capacities were then correlated with sorbent prices to give oil sorption costs. Methods employed during this first evaluation were then applied in a subsequent laboratory evaluation in which sorbent capacities were determined both in oil-only and oil/water environments. During the course of these evaluations, maximum sorbent capacity was correlated and compared with the viscosity of the oil recovered. Simulated field tests in outdoor tanks were also conducted in which crude oil and No. 2 fuel oil were spilled in order to determine both the oil pick-up capacity and the oil/water ratios of the sorbents under study. Of those sorptive materials examined, the synthetic polymeric sorbents exhibited the highest oil pick-up capacities and oil/water ratios"--Abstract.
