Chemical additives for improving oil spill control were studied. A state of art report, bibliography and evaluation were prepared. Drum and belt driven oil flow simulation tanks for oil control study were developed. Sixteen oils tested showed initial dropletting and entrainment for oil slicks on water at 0.3 to 0.6 knots, with no correlation between viscosity, density or interfacial tension. Most effective additives were non-toxic oil soluble hydrocarbon polymers, polyethylenes and ethylene-propylene copolymere, useful at low concentrations, raising initial entrainment speeds to 2 knots, short of 10 knot objective. Surface active agents did not inhibit dropletting or promote coalescence of oil or oily drops.

The interim technical report summarizes the state of the art of using chemical additives to improve the control of oil spills at increased current velocities of up to 10 knots. The report presents the current and prospective states of the art in the following areas of oil/water two-phase flow: (1) Reduction of oil/water interfacial drag; (2) oil slick gellation; (3) increase of oil/water interfacial stability; and, (4) promotion of oil droplet slick coalescence. An extensive bibliography is included with this report that contains most work conducted to date on the subjects of oil slick behavior, oil spill containment and removal, and modification by additives of oil properties.
