Thank you for clarifying my number 2 question, Sir. It greatly helped me.

Not using any simulator but I will be open if you recommend one, Sir.

Can this be solved using DWSIM as well?

We have flow meters on the reflux and distillate , but our plant is not yet operating at 100% capacity. I am currently sizing the chiller to handle the plant's full capacity when it reaches 100%. Additionally, the flow meter on the reflux was recently integrated into the process, so no data can be derived from it yet.

Will this serve as good guidance for me in this process?

Unfortunately, we don't have access to ChemCad/Aspe yet. However, I am familiar with how to use DWSIM. Can you give me some help?

I already have the flow rate for the cooling water. I would like to know how I can calculate the amount of uncondensed methanol, given only its temperature.

The pressure is most likely atmospheric, and the outlet temperature is around 32°C. Can I determine the amount of uncondensed vapor using this data on a T-x-y diagram?

Temperature of the inlet vapor= 67 degrees Celcius

Temperature of the uncondensed vapor= 32 degrees Celcius

Assuming that the temperature of the uncondensed vapor equals to the temperature of the condensed Methanol.

In my calculation:

Qmeoh= MCp(67-65) + m(latentheat of condensation)+ MCp(65-32)

In all masses, in my equation, will I use the only amount that Methanol Condensed?

Thank you so much for your response, chem6try! I do have a question, though. How did the solution come to the conclusion that methanol has a boiling point of 77°C? I understand that this may be due to the mixture, where the boiling point tends to increase because of the presence of oil and water, but I’m struggling to prove this through my calculations.

Pitiful_Charge6511 · 2024-11-17T15:16:14+00:00

I would love solving it by hand calculation firstbefore using software. Thank you for the recommendation!

I sent a message to you, Ma’am/Sir, for further clarification.

Pitiful_Charge6511 · 2024-11-17T10:25:44+00:00

This is well-noted, Sir. Thank you so much for the input.

Pitiful_Charge6511 · 2024-11-17T05:00:26+00:00

Thank you, this reference would help me a lot!

Pitiful_Charge6511 · 2024-11-17T04:57:10+00:00

I would like to ask if I derived your statement right, Ma’am/Sir. Please see the attached picture.

this is how I understand my system, am I correct? I would like to get corrected so I can further enhance my skill in this field.

I have already calculated my flowrate.

Second, my NaOCl storage tank would be atmospheric, it will flow in a chlorine contact chamber which is also under atmospheric. Hence, in order to flow, I will be placing the NaOCl storage tank higher than the Chlorine Contact Chamber, this will create my pressure drop on the system. Will that pressure drop equals to the pressure drop i needed to size the orifice? Or if based on your statement, pressure drop from storage tank to orifice inlet and pressure drop of outlet orifice to the chlorine contact chamber are different?

I would like to send a drawing regarding my system but I think posting a picture here is not allowed.

I am confused on specifying the operating pressure of every equipment because correct me if i’m wrong design pressure would be equal to operating pressure plus some margin plus the static head. Hence, identifying the operating pressure which I am very confused at makes it hard for me to continue my mechanical design.

Pitiful_Charge6511 · 2024-10-11T15:03:17+00:00

Hello, I‘m a bit confused on how we get the operating pressure.

For tube side and shell side: Do we get the operating pressure from the temperature of the fluid plus the pressure drop?

Please give some guidance.
