Description

Technical Field

[0001] This utility model belongs to the field of gas-liquid separation technology, specifically relating to a gas-liquid separation device for butanol and octanol tail gas butyraldehyde. Background Technology

[0002] The industrial production of butanol and octanol generates a large amount of tail gas, which contains a large amount of unreacted reactants such as propylene, propane, and butyraldehyde. These reactants can be recycled, such as butyraldehyde. In the existing technology, a gas-liquid separator is used to separate and recover the butyraldehyde and the gas, based on their different densities.

[0003] Existing butanol and octanol tail gas butyraldehyde gas-liquid separation devices still have some defects. Most of them do not have a filtration function and cannot remove dust in the tail gas, which makes them inconvenient to separate gas and liquid. In addition, during the gas-liquid separation, liquid will adhere to the surface of the separation plate, affecting the normal passage of gas and reducing the separation efficiency. To address this, we propose a butanol and octanol tail gas butyraldehyde gas-liquid separation device. Utility Model Content
