Discussion on the hydrogen circulation pump in diesel hydrotreating units
Thread Content
Our company has newly installed a 300,000-ton diesel hydrogenation unit; for the hydrogen circulation pump, a reciprocating type is being considered initially, whereas in the past our company has always used steam-driven centrifugal pumps. The circulation rate is controlled at 505 to regulate the hydrogen circulation volume. How to control the hydrogen circulation rate using a reciprocating machine? Is it stable? Could everyone discuss it? ?
Generally, large installations use centrifugal compressors, while smaller installations employ reciprocating compressors. Centrifugal compressors operate more reliably and usually do not require maintenance. However, centrifugal compressors have certain requirements regarding the molecular weight of the compressed medium and the minimum operating pressure, whereas reciprocating compressors do not have such requirements. For flow regulation in reciprocating compressors, a load regulator can be used; the settings are usually 100%, 50%, and 0. Three traffic volumes. Secondly, the method of using the exit to return to the inlet can be employed; both methods are available in our device.
Hello, Floor 2. You mentioned two methods – which one should be used during normal production? Could you be more specific? Just send the relevant materials to my email! Thank you so much! ! ! :Handshake: My email address is WYX3975794@126.COM.
