Total failure of the liquid level gauge in the diesel hydrogenation reactor
Thread Content
A diesel hydrogenation unit with an annual production capacity of 300,000 tons utilizes the patented medium-pressure hydrogenation technology based on fully liquid-phase reactors developed by DuPont in the United States. The reactor features four bed layers and four level gauges; radar level gauges and magnetic float level gauges are used together. Over time, however, the radar gauges break down, and the magnetic float gauges also start to malfunction from time to time. Do any experts have any good solutions to these problems? Reaction pressure: 8.9 MPa, temperature: 350
Your description of full-liquid-phase medium-pressure hydrogenation sounds too fancy; I don’t understand how it works
The reactor has four beds, each containing hydrogen, with the catalyst suspended in the oil
Adding a set of differential pressure measurement system provides an intuitive and reliable way to monitor the pressure in liquid-phase hydrogenation.
It is possible that impurities in the diesel and catalyst debris have jammed the float ball inside the magnetic flap. Isn’t your facility equipped with a raw material backwash system to remove impurities?
