We have an unused pressure vessel available and we’re looking to use it as a buffer tank to pump process recovered water and also pump out of the vessel to another process. The vessel has an exiting pressure relief and vacuum relief valve. Given it’s a pressure vessel with no vent I think it’ll get harder to pump water into as the air compresses and also a risk of low pressure when pumping out. Will I need to convert the tank to an atmospheric tank

The temperature sensor in the air compressor kept tripping and breakdown. We had replaced it 2 weeks ago. The type of environment is dusty and am currently on a lookout for a permanent solution. Really would appreciate any help.

Hello, I am a final year chemical engineering student, I have a module about bioprocess engineering. one of the experiment that we did is measurement of kla in an aerated stirred tank. for the kla value when I calculated it and when I plotted the linear graph I got a negative value, and I am wondering is that legit or kla value shouldn't have any negative values? Thanks in advance.
