| titleOfInvention | The method of butanol and octanol waste liquid back end hydrogenation recycling butanol and octanol |
| abstract | The separation method of butanol and octanol waste liquid back end hydrogenation recycling butanol and octanol disclosed by the invention belongs to the technical field of octyl alconyl, in order to solve the problems, such as that utilization rate of the existing technology is not high or energy consumption is high, it proposes and a kind of the aldehyde in butanol and octanol waste liquid is first hydrogenated to alcohol, using distillation process, obtain butanol and octanol products, specific steps include dehydration, separating butanol, recycle butanol, separate miscellaneous oil, separate octanol, de- octanol, the butyraldehyde that separates of tower top will be dehydrated to add hydrogen and the octenal that miscellaneous oily tower top separates is added hydrogen and first passes through each plus after hydrogen and takes off light process, it is returned to during separating butanol and separation octanol etc. respectively again, the utilization rate of butanol and octanol waste liquid can be significantly increased, greatly improve utility value, increase economic benefit.The present invention can reduce the difficulty of rectification cell, reduce separation costs by adding the process of hydrogen to reduce the complicated composition degree of material. |
