摘要

Abstract

Using catalytic oxidative absorption for H

S removal is of great interest due to its distinct advantages. However

traditional scrubbing process faces a great limitation in the confined space. Therefore

there is an urgent demand to develop high-efficiency process intensification technology for such a system. In this article

S absorption experimental research was conducted in a rotating packed bed (RPB) reactor with ferric chelate absorbent and a mixture of N

and H

which was used to simulate natural gas. The effects of absorbent pH value

gas-liquid ratio

gravity level of RPB

absorption temperature and character of the packing on the desulfurization efficiency were investigated. The results showed that H

S removal efficiency could reach above 99.6% under the most of the experimental condition and above 99.9% under the optimal condition. A long-time continuous experiment was conducted to investigate the stability of the whole process combining absorption and regeneration. The result showed that the process could well real

ize simultaneous desulfurization and absorbent regeneration

and the H

S removal efficiency kept relatively stable in thewhole duration of 72 h. It can be clearly seen that high gravity technology desulfurization process

which is simple

high-efficiency

and space intensive

has a good prospect for industrial application of H

S removal in confined space.
