Hello everyone,
I’m currently working on the commissioning of a cold water supply system for a production plant. The system includes duplicated pumps with a tank to ensure a continuous supply of cold water.
I’ve been reviewing the P&ID and the overall design of the installation, and I’ve...
Hello everyone,
I’m working on a project involving the centrifugation of APIs where solvents are used. The centrifugation room is equipped with a ventilation system that provides 10 air changes per hour.
I have two motors that I plan to use for the centrifuge's hydraulic and cooling systems...
Hi all,
I have the following AHU system. I undestand that I have a Feedback control to control the Clean Room and a Feedforward control to control any exterior disturbance.
But there is a third TT at the outlet of AHU that I dont know what it used for... Any help / idea?
Hello to all,
I have a small question. I have a proces as show in the pic:
We pressurise an expansion tank with Nitrogen to 300 mbarg. The vent outlet of the tank has a control valve at 400 mbarg because it is 1.5 m below the thermal oil process piping (1.5 m oil column is 0.100 mbarg).
I...
Hello to all,
We are calculating PSV for two phase scenario and we have noticed that the mass quality fraction (x0) is too low, about 0.0006, that mean that from 100 kg/h 99.9994 kg/h are liquid and only 0.0006 kg/h are vapor.

For example, I must install a fan with a dust filter (point 3) in this branched pipe system.
The pressure drop from point 1 to 3 is bigger than the point 2 to 3. Both are open to the atmosphere.
For calculate the mmWG I have to reach I will sum the pressure drop from 1 to 3, the pressure...
Dear all,
We know the HEM method to sizing the valve but we have no idea how to size a valve that arrive fluid in two phase... for example, there is a fire and the reactor jacket is heating... so the fluid is vaporizing and arrive in two phase to the PSV...
I want to ask if there is any...
