Regarding logistics, should pressure be applied using a pump first or should heat exchange take place first?
Thread Content
The problems I encountered while working on the process started with simulations using Aspen, but it was found that the impact was minimal; so what about in actual engineering applications?
If it’s about cooling, then it definitely has to be cooled first before hitting
When heating, it is usually done by pumping first and then heating; you need to take into account the operating conditions of the pump
Heat transfer media cause significant damage to pumps and seals; it is generally transported in cold conditions. Cold media have high viscosity; in some cases, it is so high that they cannot be transported, forcing transportation to be carried out while they are still warm
Not necessarily; many bottom pumps draw the fluid out before it is heat-exchanged and cooled.
Under normal circumstances, the fluid first flows into the pump; after pressure is increased, it enters the heat exchanger, where the flow rate is increased to boost the heat exchange efficiency. Special cases will be considered separately
Based on the conditions at the site, the feed material is usually pressurized first before heat exchange takes place; heating it first can have an adverse effect on the stage pumps. However, the situation is not necessarily the same; some hot reaction products, due to low pressure, need to be pressurized using pumps through subsequent process equipment before they can be transported. Analyze each case on its own merits
Agree with what was said above; it can’t be generalized – each case needs to be considered individually
It depends on the conditions: jelly is tastier when it’s cold, while eggs are tastier when they’re hot.
This metaphor is quite vivid,,,
Specific processes require specific handling; it’s not possible to apply a one-size-fits-all approach!
