  • METHODS AND COMPOSITIONS FOR SCAVENGING SULFIDES AND CARBON DIOXIDE FROM PETROLEUM AND NATURAL GAS
    Publication number: 20190322948
    Abstract: An aromatic imine blend includes an aromatic imine and a de-foaming agent, surfactant, amine, hydrotrope, alcohol, amino acid, ether, alkalinity stabilizer, or a combination thereof. A process of removing carbon dioxide or a sulfide from oil, water, or natural gas includes supplying an oil, water, or natural gas stream and contacting the oil, water, or natural gas stream with an aromatic amine blend. The aromatic imine blend includes an aromatic imine and a de-foaming agent, surfactant, amine, hydrotrope, alcohol, amino acid, ether, alkalinity stabilizer, or a combination thereof.
