INHIBITING NAPHTHENATE SOLIDS AND EMULSIONS IN CRUDE OIL

NAPHTHENIC ACID SOLIDS AND/OR EMULSIONS CAN BE INHIBITED BY INTRODUCING AN ADDICTIVE TO CRUDE OIL PRIOR TO OR CONCURRENT WITH THE DEPROTONATION OF THE NAPHTHENIC ACIDS PRESENT IN THE CRUDE OIL. THE ADDITIVES MAY BE SURFACTANTS AND CAN BE QUATERNARY AMMONIUM COMPOUNDS, QUATERNARY PHOSPHONIUM COMPOUND...

Summary:NAPHTHENIC ACID SOLIDS AND/OR EMULSIONS CAN BE INHIBITED BY INTRODUCING AN ADDICTIVE TO CRUDE OIL PRIOR TO OR CONCURRENT WITH THE DEPROTONATION OF THE NAPHTHENIC ACIDS PRESENT IN THE CRUDE OIL. THE ADDITIVES MAY BE SURFACTANTS AND CAN BE QUATERNARY AMMONIUM COMPOUNDS, QUATERNARY PHOSPHONIUM COMPOUNDS, AND MIXTURES OF BOTH. THE ADDITIVES MAY ALSO BE LINER COMPOUNDS HAVING AT LEAST TWO CARBOXYLIC ACID OR ACRYLIC ACID FUNCTIONAL MOIETIES.
