In the light of waste prevention in the conventional acrylic acid (AA) removal process uses a water washing tower, we report on an experimental evidence of a proof-of-concept alternative process using TiO2 ceramic membrane contactors. Experimental results allow us to estimate the mass transfer coefficient of the proposed membrane system, being 0.003 m3/m2h. Based on this value, we perform a techno-economic assessment (TEA) for the acrylate production process using membrane contactors for AA removal. The acrylate production cost is estimated with a focus on downstream processing. The results are benchmarked with the process using a water washing tower for AA removal. 2-ethylhexyl acrylate (2-EHA) is taken as the model product with a yield of 20,000 ton/year. We find that for the membrane contactors to be cost competitive with the water washing tower, the AA mass transfer coefficient needs to increase to 0.005 m3/m2h, keeping the other parameters constant.
