Solution to the clogging problem in MTO quench towers / Author/Source: Sinochem New Network / Date: 2021-10-21 / Clicks: 14 Recently, Tianjin Ruide Sain New Materials Development Co., Ltd. developed a quench water detergent along with corresponding application solutions, which addressed the scaling issue in the water systems of Methanol-to-Olefins (MTO) plants using UOP processes. The scaling problem in the water system of MTO units has always been a challenge that hinders their long-term stable operation, while for the UOP process, the issue of cooling tower blockage is even more prominent. After the UOP process unit has been operating for a certain period of time, the circulation rate at the top or middle of the quench tower tends to decrease, and the blockage problem worsens, to the point where effective circulation can no longer be established, thereby affecting the normal operation of the unit. To address this issue, the company’s technical staff developed a series of quench water detergent products, which were applied in Jutai Energy’s MTO unit. After its application, the circulation rate in the middle section of the quench tower, where clogging was most severe, was increased from less than 50% of the designed value to the standard designed rate, thereby reducing the operating pressure on the plant and ensuring its stable operation.
The clogging problem in the MTO quench water and washing water systems can be alleviated to some extent by using chemicals, but this does not provide a permanent solution. The catalyst in the water cannot be removed, so it only provides a temporary solution rather than a permanent one. With the addition of chemicals, higher requirements are placed on water treatment.
Ask the person upstairs from Haiyou: Is the quench tower a plate tower? Can using anti-gambling wheels solve the problem?
Even with a herringbone tray, the blockage still exists. In my opinion, the core issue lies in removing the catalyst carried in the water in order to solve the problem fundamentally. Other methods can only slow things down; they cannot solve the problem at its root.
