SAROL DEF

Diesel Exhaust Fluid

Description

SAROL DEF (Diesel Exhaust Fluid) Urea Solutions are produced by combining pure liquid urea from the urea process with clean plant steam condensate to produce the desired concentration. The resulting DEF solution is free of any chemical additives such as formaldehyde.


Applications

DEF is marketed as ultra clean liquid fuel for catalytic abatement of nitrogen oxide emissions.

 • The decomposition of DEF into ammonia, carbon dioxide and steam provides a safe way to produce the ammonia fuel source.

There is no need to have containers of compressed liquid ammonia in remote locations that are difficult to secure.

DEF is effective in controlling the emission of nitrogen oxides from stationary sources such as power plants as well as from diesel powered cars, trucks, trains, ships and heavy equipment


Features & Benefits

•    Effective in controlling the emission of nitrogen oxides.

•    Non-toxic, non-hazardous and formaldehyde free.
