Industrial application of octanol upgrading and renovation in the butanol octanol plant
Based on the successful transformation of the butanol and octanol unit in the fertilizer plant of Jilin Petrochemical Company of China National Petroleum Corporation,and in response to the production bottleneck of low quality of n-isobutyraldehyde products and excessive octanol loss in the unit,the difficulties in the transformation of the isomer separation tower,octanol pre distillation tower,and heavy fraction separation tower were analyzed.Based on this,the use of ADV high-efficiency tray,ADV-TDD suspended downcomer technology,and SP-S high-performance packing was adopted,The one-time achievement of improving the quality of butyraldehyde and isobutyraldehyde products and reducing octanol consumption further enhances the core competitiveness of the device,providing important support and reference for improving the quality of butyraldehyde and isobutyraldehyde products in the butanol and octanol industry.
