Reactor corrosion and salt deposition problems severely restrict the
industrialization of supercritical water oxidation. Transpiring wall
reactor can effectively weaken these two problems through a protective
water film formed on its internal surface. In this work, the effects of
key structural parameters on water film properties of transpiring wall
reactor were explored by numerical simulation, and established models
were validated by comparing simulation and experimental values. The
results show that transpiration water layer, transpiring wall porosity
and inner diameter hardly affected organic matter degradation.
Increasing transpiration water layer and transpiring wall porosity
reduced reactor center temperatures in the middle and lower zones of the
reactor. Increasing transpiration water layer, transpiring wall porosity
and inner diameter decreased water film temperatures but increased water
film coverage rates. Increasing reactor length affected slightly on the
volume of the upper supercritical oxidation zone but enlarged the
subcritical zone.01 Mar 2021Submitted to AIChE Journal 03 Mar 2021Submission Checks Completed
