Description
図1に示された構造の分離壁型蒸留塔にIPAを含むフィードを供給し、精製工程を進行した。上記で分離壁型蒸留塔の段数は、フィードの組成による蒸留曲線によって算出された理論段数として適用した。フィードとしては、IPA 97.5wt%〜98.5wt%を含み、含水量が0.5wt%〜1.0wt%(5,000ppm〜10,000ppm)であり、その他エチルアルコールなどを含む不純物を0.3wt%〜1.0wt%含むフィードを使用した。図1のように、上記フィードを蒸留塔の上部供給領域に導入し、精製工程を進行した。導入時に、流量は、6,250Kg/hr程度に維持し、フィードの温度は、約90℃程度に維持した。正常状態で、蒸留塔の上部運転圧力が1.1Kg/cm2程度であり、上部運転温度が約73℃程度になり、下部運転温度が108℃程度になるように維持しながら精製を進行した。精製されたIPAを含む生成物は、分離壁型蒸留塔の下部流出領域に収得した。
フィードとして含水量が0.25wt%(2,500ppm)であるフィードを使用したことを除いて、実施例1と同一の方式で精製を進行した。
分離壁型蒸留塔の上部運転温度を40℃にしたことを除いて、実施例1と同一の方式で精製を進行した。
分離壁型蒸留塔の上部運転温度を140℃にしたことを除いて、実施例1と同一の方式で精製を進行した。
分離壁型蒸留塔の上部運転温度を35℃にしたことを除いて、実施例1と同一の方式で精製を進行した。
分離壁型蒸留塔の上部運転温度を150℃にしたことを除いて、実施例1と同一方式で精製を進行した。
分離壁型蒸留塔の下部運転温度を85℃にしたことを除いて、実施例1と同一の方式で精製を進行した。この場合、消耗する熱量自体は低く現われたが、凝縮器に使用される冷却水の温度が非常に低くなり、したがって、工程の設計条件を変更しなければならない問題が発生した。
分離壁型蒸留塔の下部運転温度を180℃にしたことを除いて、実施例1と同一の方式で精製を進行した。
フィードとして含水量が1.1wt%(11,000ppm)であるフィードを使用したことを除いて、実施例1と同一の方式で精製を進行した。
