Dispersants are widely used to stabilize various industrial and artisanal products, such as paints, ferrofluids, and salad dressings. The plasticizers or superplasticizers , used to improve the workability of pastes like concrete and clay , are typically dispersants.
Oil dispersant mechanism of action. An oil dispersant is a mixture of emulsifiers and solvents that helps break oil into small droplets following an oil spill.Small droplets are easier to disperse throughout a water volume, and small droplets may be more readily biodegraded by microbes in the water.
Besides their use as dispersants lignosulfonates are also good binders. They are used as binders in well-paper, particle boards, linoleum flooring, coal briquettes, and roads. They also form a constituent of the paste used to coat the lead-antimony-calcium or lead-antimony-selenium grids in a Lead-acid battery.
Chemical dispersants are used in oil spills to mitigate the effects of the spill and promote the degradation of oil particles. The dispersants effectively isolate pools on oil sitting on the surface of the water into smaller droplets that disperse into the water, which lowers the overall concentration of oil in the water to prevent any further ...
During a Senate hearing on the use of dispersants, Senator Lisa Murkowski asked EPA administrator Lisa P. Jackson whether Corexit use should be banned, stating she didn't want dispersants to be "the Agent Orange of this oil spill". [67] [68] [69] According to a NALCO manual obtained by GAP, Corexit 9527 is an “eye and skin irritant. Repeated ...
These low range water reducing dispersants are commonly manufactured from lignosulfonates, a by-product from the paper industry. High range superplasticizers (dispersants) have generally been manufactured from sulfonated naphthalene condensate, although polycarboxylic ethers represent more modern alternatives. Both of these high range water ...
Dispersit is unique among U.S. Environmental Protection Agency-rated dispersants in being the only one rated as 100% effective against South Louisiana crude oil, and it is among the least toxic, according to EPA tests. [4]
In the petroleum industry, 2-butoxyethanol is a component of fracturing fluids, drilling stabilizers, and oil slick dispersants for both water-based and oil-based hydraulic fracturing. [ 11 ] [ clarification needed ] When liquid is pumped into the well, the fracturing fluids are pumped under extreme pressure, so 2-butoxyethanol is used to ...
