Abstract:

The difficulties in the operation of quench oil system in ethylene plant are analyzed in this article. The causes of polymer blockage in gasoline fractionator are summarized, and the process of polymer blockage is analyzed. It is proposed that the concentration of polymer components and the temperature in gasoline fractionator are the key factors influencing the polymer blockage. The reasons for the tiny coke powder in quench oil system are analyzed, the effective measures for removing coal powder are proposed, and the important parameters to be focused on during the operation of quench oil system are pointed out.
