Hi, I'm working in a refinery.
These days, I'm studying about Steam Cracking.
In steam cracker, there is a heat exchanger called transfer line exchanger, which is different from S/T Heat exchanger.
It's design makes effluent and water/steam flow the same upper side.
I'm wondering why they use transfer line exchanger instead of conventional S/T heat exchanger.
I guess it's because there are just straight tubes in exchanger, so it's good not to make cokes or pressure drops.
(or it could take shorter time to cool effluent than in S/T heat exchanger...)
Are they only reasons for using transfer line exchanger? or other main reasons for that?
