FIELD: petroleum processing.
SUBSTANCE: invention relates to neutralization of acid sludge in electromagnetic apparatuses using alternate electromagnetic field energy and operated at frequency 50 Hz, electromagnetic field intensity 450 A/cm, and electromagnetic field induction 0.3 Te without addition of neutralization agent.
EFFECT: abruptly reduced acid number, conductivity of stock, and increased specific resistance reflecting neutralization of acid sludge.
