Abstract:

A method of remediating pesticides from an agricultural oil includes mixing a reaction solvent, a reducing agent, and an agricultural oil into a reaction mixture in a reaction vessel, controlling the temperature of the reaction mixture, producing a pre-neutralization mixture including a separation solvent, transferring the pre-neutralization mixture into a neutralization reactor that contains a neutralization agent, mixing the pre-neutralization mixture with the neutralization agent and allowing separation into an aqueous layer and a separation solvent layer, draining the aqueous layer, and distilling the separation solvent in the separation solvent layer from the remediated agricultural oils. A system has a reactor vessel, the reactor vessel having one or more inlets to allow a reducing agent, the agricultural oil, the separation solvent, and other additives as needed to produce a reaction mixture, a temperature control unit to control a temperature of the reaction mixture at a predetermined temperature for a predetermined time, a neutralization vessel fluidically connected to the reactor vessel to receive the reaction mixture from the reactor vessel, the neutralization vessel having an inlet to allow a neutralization agent to be introduced into the neutralization vessel to produce a neutralized reaction mixture, and a valve arranged at a bottom of the neutralization vessel to allow an aqueous phase of the reaction mixture to be drained from the neutralization vessel.
