So…what’s new? I finally got around to updating my blog- so see my latest posts about my trips to Xi’an and Beijing! It’s been over a month since my last update that wasn’t really an update so I figured I would also write a quick summary of springtime in Wuxi. I turned 22 at the end of February. It was quite calm compared to my 21st birthday in New Orleans (hah) but I had a blast regardless. I hired a Chinese tutor! I got really sick the first week of March. I went to KTV with my friends.

中国化工产品指南
一种三氯氢硅加压提纯方法及其装置，将待提纯的三氯氢硅、四氯化硅、氯硅烷混合液输入提纯塔的加料口，混合液经提纯塔下流至蒸馏釜，蒸馏釜压力为0.15MPa 1.5MPa、温度为70 200 从蒸馏釜出来的蒸汽进入提纯塔中进行热量与成分的交换与分离，提纯塔内的操作温度为40 150 ，沸点低的三氯氢硅组分在汽相中富集，沸点高的四氯化硅组分在液相中富集，经过多次汽化、冷凝，最终在汽相中得到三氯氢硅汽化组分，然后进入塔顶水冷凝器，经循环水冷却、冷凝成三氯氢硅液体。 本发明可使同样塔径的提纯塔产量提高 50 减少了冷冻所需的设备投资和设备运行费用，塔顶水冷凝器的换热效率提高约15 ，大大降低了能耗。
