D. Nemec et al., Gravimetric method for the determination of liquid holdup in pressurized trickle-bed reactors, IND ENG RES, 40(15), 2001, pp. 3418-3422
A gravimetric method for the determination of liquid holdup was successfull
y employed in a high-pressure-operated trickle-bed reactor. The method has
proven to be a reliable, fast, and relatively simple way of measuring liqui
d holdups under high pressures, despite opposite indications of previous wo
rks done in this field. A detailed description of the apparatus and measuri
ng procedure is given.
