Memory techniques for each heat exchanger in the atmospheric and vacuum distillation unit
Thread Content
I’m a complete beginner when it comes to atmospheric and vacuum distillation units. There are many side streams in such units, as well as a large number of heat exchangers. After studying for some time, I still can’t remember which heat exchangers are associated with each side stream. I’m asking the more experienced colleagues for any quick memory aids or techniques they might have; I really appreciate any help!
Try to assign numbers to each oil line – Constant 1, Constant 2, Constant 3, Constant 4, and Constant Bottom – and see how many digits the identification numbers of your heat exchangers have. If only the last digit differs, then record just that last digit. For example, the identification number for the heat exchanger that the Constant 1 line passes through, from the tower outlet to the tower inlet, is a sequence of digits. After practicing for a while, you’ll remember the specifics. This is just a trick used at the very beginning of learning; it’s based on experience: lol
At that time, I simply recorded different tag numbers: one set for the side lines and another set for the crude oil, and then I compared the two sets, which made everything clear.
