和文要約和文要約等以下本編抜粋:1. 研究開発の内容及び成果等 (1) 2012年度の実証試験スケジュールの精査 2012年度のプラントの定修時期等から実証試験スケジュールの精査を行なった。その結果、表1のようなスケジュールとした。実証試験装置の建設を4月から、試験の開始が10月からとなる。なお、実証試験の開始時期に変更はない。 (2) 熱交換器の検討 膜分離モジュール内では気体状態のIPAからわずかに水が脱水された後、それぞれ回収タンクに回収されるが、回収タンクに導入するため液化が必要となる。
英文要約We reviewed the demonstration examination schedule from periodic repair in 2012.
As a result, we decided to start the construction of demonstration experimental equipment from April.
The gas phase IPA is dehydrated by the inorganic nanoporous membrane. Afterwards, the dehydrated water is collected in recovery tank. Therefore, it is necessary to condense the dehydrated water. Because the water of the membrane separation module exit is about 150 degrees Celsius, and 4 - 6Kpa, it is necessary to cool off with a heat exchanger.
Therefore, we examined possibility of cooling with water by a calculation. We calculated a saturated steam pressure to temperature. It is necessary to cool off to 30 degrees Celsius to let dehydrated water liquefy in 4 - 6kPa. It is usually difficult to cool off 150 degrees Celsius dehydrated water to 30 degrees Celsius by water because water temperature is around 30 degrees Celsius. Therefore, we decided to install a chiller. On the other hand, we found it is able to condense IPA by water. However, pipes of exchanger is over 2 meters. Because the setting point of the demonstration experimental equipment is limited, we decided to utilize a chiller for cooling the dehydrated water.
It is planned to change various membrane separation modules each 200-400 hours in this project. When we installed membrane separation modules vertical, the height of a membrane module is over 1.5 meter. We decided to install the membrane separation module horizontal because the high place work for exchanging membrane modules in the factory become complicated. If we adopt coupler as a pipe fitting of a membrane separation module, we can simplify to exchange the membrane modules. However, we apprehend the performance of membrane become lower by occurring slight pressure drop. We canceled using a coupler. Therefore, we arranged setting position. In other words, we install a membrane separation module in the front to change membrane modules easily. And we will install other device in the back position.
We based on each examination items and devised flow diagram of the demonstration experimental equipment. Chiyoda indicated that we can reduce much energy by changing azeotrope tower to pressurization stripper. Water content changes from about 12% to 35% by changing tower specification. In the light of the demonstration experiment using higher water content IPA, we decided to put water line beside IPA lines for feed stock.
