The problem of inaccurate feed flow rate in hydrogenation reaction
Thread Content
The feed flow rate of the hydrocracking reaction where I work has never been allowed to be measured. The design is an orifice plate, two pairs of pressure points, and four transmitters. In order to avoid false flow signals, a high-pressure plunger pump has been added to the pressure pipe. However, during use, the four flow displays all indicate different directions, and often one or more points are broken, causing the automatic control valve that controls the flow to always be in manual mode. How can I solve this problem?
You can choose a flow meter that can measure high viscosity.
The application of mass flow meters to crude oil measurement may not necessarily solve the problem. I don’t know if ABB’s mass flow meters have such a mass flow meter for large viscosity media. We use an oval gear flowmeter, which is quite stable during use. :handshake
I am operating in high pressure hydrogenation with a pressure of 13.2mpa and a feed of 248t/h. I wonder if I can use an oval gear flowmeter?
