How should the energy consumption of atmospheric and vacuum distillation columns be considered?
Thread Content
Everyone, has anyone ever conducted an energy consumption analysis of atmospheric and vacuum distillation units? Especially when conducting an energy consumption analysis of atmospheric pressure columns, how is this taken into account?
Are there any relevant materials on the analysis of energy consumption in towers?
1. Sinopec has a small software for calculating baseline energy consumption; you might want to take a look at it! 2. Regarding the energy consumption of the atmospheric pressure tower, you can conduct an energy balance for it and then perform an exergy analysis! 3. There seems to be a book titled \"Methods for Energy Saving in Chemical Processes\", which specifically covers the calculation methods and analysis related to the three energy consumption stages in atmospheric and vacuum distillation units!
Excuse me, someone upstairs: where can I obtain Sinopec’s benchmark energy consumption software? Thank you!
The operating energy consumption and design energy consumption of atmospheric pressure columns are concrete manifestations of the various aspects related to the energy consumption of distillation columns that are taught in universities. . . The atmospheric pressure tower is a vapor-liquid two-phase feed steam stripping distillation tower; its energy consumption arises from the amount of steam used and the cooling load at the top of the tower. . . Less steam injection means less water cooling. . . Energy consumption can be reduced. . . . :lol Last edited by wangsc on 2009-2-25 11:51 ]
A proper feed plate, reflux ratio, and appropriate operating pressure can all help reduce energy consumption; therefore, the design of the tower needs to be optimized
Would you like to obtain Sinopec’s benchmark energy consumption software? I have it; I learned it before, but I don’t know how to send it to you
Sinopec’s benchmark energy consumption software is flawed, as it presets a benchmark based on a specific unit within Sinopec – for example, catalytic cracking is based on a catalytic unit operated by Shanghai Petrochemical. But when it comes to a specific set of devices or one’s own devices, the differences are enormous. I recently learned to use the ASPEN software, and I think it’s quite good because it relies on basic data for calculations and provides suggestions for optimization. But you need to put in real effort to learn it*.
Thank you for all your suggestions; I plan to conduct an analysis based on energy balance.
