Determination of the heat exchange area of the heat exchanger
Thread Content
According to the process, how is the heat exchange area of the heat exchanger determined? Or in other words, how to verify whether the heat exchange area of the heat exchanger provided by the design institute is appropriate? The process medium is propane; the inlet temperature of the distillation tower condenser is 58 degrees, while the outlet temperature is 30 degrees...... The cooling medium is circulating water, with an inlet temperature of around 30 degrees.
The design institute determines the effective heat exchange area of the heat exchanger based on material balance and energy balance. Equipment design generally involves selecting materials and calculating the appropriate type of heat exchanger based on factors such as fluid flow rate, temperature, effective heat exchange area, and the properties of the fluid. Once a preliminary selection has been made, a detailed structural design is carried out in accordance with relevant specific equipment standards, followed by adjustments to the heat exchanger. After the final design is completed, a design institute will determine whether it meets the process requirements.
Moderator, I guess the original poster posted this because they had objections to the design review process, not because they wanted to ask about the design institute’s workflow. Just based on what the poster described, there’s a problem: in a distillation tower, the propane gas is at 58 degrees, and it needs to be condensed to 30 degrees, yet the cooling source is circulating water at around 30 degrees, so this is definitely not feasible. Is the poster asking whether a two-stage condensation system is being used, with a low-temperature water condenser at the rear end?
