R&D themes and Progress 1. Consideration of testing apparatus for acidic solvents
We had often experienced some problems in the previous type of testing apparatus. In particular; Sudden stop due to the malfunctioning of permeate sensor, Initial solvent concentration change, Difficulty with permeated water draining due to the structure of condenser. So, we improved the permeate sensor (1-1), redesigned circulating system of the apparatus (1-2) and designed new structure of condenser (1-4). And more, in order to have acid-proof performance with the new testing apparatus, we adopted proper materials, for example, SUS316, perfluoroelastomer (FFKM) and PTFE for mounted devices and small parts(1-3, 1-5). 2. Design of testing apparatus for acidic solvents Based on the studies described above, we designed the acid-resistancy testing apparatus. We finished the design on July, 2017 and submitted the drawing and the specification to WASEDA Univ. who is co-contractor of this research. However, since the equipment assembling company was unfortunately bankrupted on September, 2017, we changed the company to another one. The delivery date will be the end of April, 2018. 3. Acceleration test to evaluate the life of zeolite membrane 3-1 Data collection to determine the acceleration factors of detorioration of membrane under water rich conditions We observed the time course of separation factor (alpha value) to judge the membrane life. “Water concentration” and “operation temperature” were taken as the acceleration factors. Further, we have tried to find a simple method to evaluate the membrane life. We have conducted immersion tests and have compared its data with those obtained from actual dewatering test by 24/7 running testing apparatus. 3-2 Data collection to determine the acceleration factors of the deterioration of membrane under acidic conditions We will start these tests from May, 2018 after the new apparatus designed in chapter 2 is installed. 4. Development of the methods to analyze inorganic membrane structure 4-1 Data Collection to determine the acceleration factor of deteriotratio of membrane under acidic conditions We will start to collect data from May, 2018 after the new apparatus, designed in chapter 2, is installed. 4-2 Comparison of membrane condition before and after the deterioration We will elucidate how membrane deterioration occurs by analyzing the membrane structure before and after the deterioration. We will try to establish the methods to analyze the structures properly.
