FIELD: chemistry.
SUBSTANCE: method comprises the following steps: a) cooling the olefin stream in a quench system to obtain a first fraction containing olefin and a second fraction containing condensed water and entrained solid matter, wherein the quench system includes a surface structure and at least a part of the surface structure is in contact with the condensed water; b) injecting an anti-clogging agent containing a water-soluble ionic material into the quench system in an amount required to maintain a zeta potential of the entrained solid particles in the second fraction and an effective zeta potential of the surface of the quench system in contact with the condensed water both in a positive range or both in a negative range, and c) separating at least a portion of the second fraction from the first fraction.
EFFECT: use of the present method reduces clogging of olefin streams.
