Description:

Repsol YPF’s La Pampilla refinery began using a Zimpro® wet air oxidation (WAO) system for the treatment of refinery spent caustic in 2005. The spent caustic comes from a variety of sources including caustic treatment of gasoline, kerosene, and LPG. Prior to installing a WAO system, the refinery was dependent on less satisfactory disposal options. The WAO system allows for on-site treatment without the production of odorous off-gas. System performance includes high chemical oxygen demand (COD) destruction and complete destruction of sulfides and mercaptans to below analytical detection limits. WAO transforms the material from an odorous and toxic feed to a readily biodegradable effluent that is free of noxious odors. The effluent is discharged to the sea.
