The theme of the graduating design is “design of gas separation soda-washing tower” .Tower equipment is an very important operation unit in chemical industry and petroleum industry. Tower equipment is for mass transfer and thermal transfer by making gas and liquid amply contact each other. Such as the operation of rectification, absorbing, extraction and washing can be completed by tower equipment. The gas separation soda-washing tower is a part of the isomerizing equipment. The purpose of the tower is to absorb HCl by soda washing. It is also a Rasching ring (a causul packing ring) packed tower. Its medium is H2 and PAH, parameter is shown below:
Design temperature: 120℃
Design pressure: 1.18Mpa
Keywords: Soda washing tower, packed tower, Rasching ring
