Diesel hydrogenation high-pressure heat exchanger
Thread Content
This type of heat exchanger is vertical and does not touch the ground; those I’ve seen before were of the threaded locking ring type, placed horizontally on the ground. What type is this heat exchanger when seen for the first time? (Pictures cannot be taken in the equipment area; please understand!) ）
Are you from that place? I heard that Zhenhai Refining & Chemical has a type of coiled heat exchanger that is vertical in design and replaces the high-pressure heat exchangers with threaded locking rings; it’s not very common
Check the PID and then the device description to see if it is a plate-type heat exchanger; it is likely vertical. Determine the temperature difference between the inlet and outlet It’s generally obvious; take a look at the manufacturer as well.
Coiled heat exchangers, with tubes arranged in a spiral pattern inside; they offer excellent heat exchange performance
Yes, for plate exchangers, if it’s a coiled-tube type, the manufacturer is likely Zhenhai; if it’s a plate exchanger, it’s probably Alfa Laval.
Coiled heat exchangers are still widely used today
