Energy consumption calculation for atmospheric and vacuum distillation units
Thread Content
How to use the data obtained from AspenPlus to calculate the energy consumption of a atmospheric and vacuum distillation unit? Has anyone done it?
The general energy consumption of a separation unit is related to the heat required for cooling or heating at the top and bottom of the tower; adding that in should give us the answer
It can’t be that simple, right! Consumption of steam and cooling water, etc., should also be taken into account
Energy consumption generally refers to the usage of steam, electricity, circulating water, low-temperature water, etc. Depending on the actual conditions, the cold and hot medium sources for the heat exchangers at the top and bottom of the tower are determined, as well as the media used in other heat exchangers; pumps and compressors typically rely on electricity. Once the medium is specified, calculating again will reveal the consumption of steam, circulating water, etc. If you need to know the corresponding reference oil value, just do the conversion by yourself
But how are steam and circulating water converted into standard oil?
There are standards; check the standards for the corresponding conversions
