METHOD OF DEMERCAPTANIZATION OF PETROLEUM, PETROLEUM DERIVATIVES, AND GAS CONDENSATE Russian patent published in 1997 - IPC

Abstract RU 2087520 C1

FIELD: petroleum processing. SUBSTANCE: process is assisted by oxidative mixture consisting of nitric acid and organic substances forming salts with nitric acid (amines, amides, ethers, alcohols) in molar ratio 1:(0.5-2.0), which is added to raw material at the rate of 0.05-1.0 mol nitric acid per 1 mol mercaptan sulfur. Process is carried out at 0-90 C. Demercaptanization degree attains 30-100%. Process is suitable to be applied directly at oil field to treat crude oil and gas condensate. EFFECT: increased (to required standards) deodorization of oil materials. 2 tbl
