- Abstract
The article presents the effect of sulfur-containing gaseous pollutants on the operation of a polymer membrane. Preliminary experimental results of the separation process of a nitrogen-hydrogen sulfide mixture simulating the impurities are presented. A nitrogen gas mixture with 100 ppm H2S was used. UBE's UMS-A5 membrane module was used for the study. The obtained results of the separation process illustrate the effect of the action of a specific pollutant on the permeation properties of the tested membrane. Changes in the concentration of hydrogen sulfide in the retentate stream were determined in relation to the time of long-term studies. The research was carried out in several stages. After the measurement process of hydrogen sulfide separation was completed, a long-term process of rinsing the membrane was carried out until it was completely cleaned of sulfur compound contamination. The results of the conducted research suggest a negative effect of sulfur compounds on the transport properties of the polymer membrane. The authors intend to continue research in this area to expand the information on the above-mentioned phenomenon to protect polymer membranes and their transport properties. The results obtained may be helpful for the development of H2S fouling management strategies that will later protect and improve the membrane's durability. This may include using special protective coatings or adding special additives to the material to increase its resistance to H2S. In this way, it can be ensured that the gas separation process will be reliable and efficient, even under H2S contamination conditions.
