Application: ECOMERICAT treating systems removes phenols from phenolic caustics by neutralization in conjunction with solvent washing using a FIBER-FILM Contactor.
Description: An ECOMERICAT system contacts the spent caustic with a slipstream of sweetened gasoline containing CO2 whereby neutralizing the spent caustic, springing the phenols, absorbing the phenols into the sweetened gasoline yielding neutral brine with minimal phenolic content.
• Minimizes spent caustic disposal cost
• Reduces the phenol content of spent caustic and increases the phenol content of sweetened gasoline thus adding value
• Operates over a wide pH range
• Simple to operate
• No corrosion problems due to the buffering effect of CO2.
