Abstract Syngas scrubbing is a crucial unit operation in the dry coal powder gasification process and plays an essential role in ensuring the stable operation of the gasification furnace. Fluent software was used to simulate the flow situation inside the syngas scrubbing tower basing on the principles of fluid mechanics. This study analyzed the internal velocity field, pressure field, component distribution and other changes with the process operation parameters as well as equipment structure, and then optimized the internal structure and operation parameters of the syngas scrubbing tower. The simulation results indicated that excessive syngas downward velocity could cause bubble formation, which may enter the cooling water pump and affect its normal operation. The inlet gas phenomenon of the cooling pump could be significantly improved by adjusting the liquid level height of the scrubbing tower or adding baffles.
