The patented Elastec NeatSweep® is a precision dispersant application system that targets oil by funneling it into the Dispersant Application Zone (DAZ) where it is applied neat (undiluted). By adding an Elastec BoomVane™, this innovative system can also be operated with a single vessel. Read our Frequently Asked Questions.

A computerized monitoring system controls the rate of dispersant application, reducing waste. It senses the speed of the system through the water and self-adjusts the pumping rate. Oil enters the dispersant application zone (DAZ) at uniform thickness allowing more precise dosing and targeting.

The system includes two sections of AirMax boom, computerized oil spill dispersant pumping unit, dispersant application unit and mixing panel. This system allows the neat (full concentration) application of oil spill dispersant directly onto the oil. As the setup is more efficient, more oil can be treated with each deployment. Most importantly, the system operates at a safe distance from operators, reducing their exposure to wind-blown chemicals.

Independent tests at Ohmsett  confirm efficiency of up to 92%.

Oil Dispersant Application System Frequently Asked Questions

What is an oil spill dispersant?
“Dispersants” as they are known generically are low toxicity chemicals that are used to break up oil on the surface of the water and promote natural degradation. They are a tool used alongside mechanical recovery and in-situ burning.

When are dispersants used?
Dispersant is typically used in large scale incidents offshore when other means are limited. Responders will go through a net environmental benefit analysis.

Where is it used?
Dispersant is not typically used in shallow or inland waters.

How is it applied?
Dispersant has to be sprayed in the correct manner to ensure effectiveness. It may be sprayed from aircraft or ships.

Does dispersant usage have to be approved?
Yes. The use of oil dispersants is regulated in most countries. Not only does the use need to be approved, the chemical itself has to undergo testing for toxicity and effectiveness.

Products Available for Use During an Oil Spill 

Dispersant use approvals in the United States 

What dispersant spray systems does Elastec offer?
We have three different systems, Elaspray is a conventional pump and arm setup, with arms that are mounted to the side of a ship. The Neatsweep is more precise as oil is funneled to a channel where the oil dispersant is applied ( dosage automatically adjusts to the speed of the vessel ), and the Boom Vane Spray (BVS). The BVS system enables vessels to get closer to shore with a wider swath than arms.
