Standard combined feed/effluent heat exchanger
Alfa Laval Packinox for catalytic reforming
Alfa Laval Packinox supplied the first Standard Combined
Feed/Effluent Heat Exchanger to a Catalytic Reforming Unit in
1982. Over a decade later, a report from the client congratulated
Alfa Laval Packinox on the heat exchanger’s constant
good performance and minimum maintenance requirements.
In one piece of equipment, Alfa Laval Packinox large welded
plate heat exchangers offer the superior efficiency of plate
exchangers together with the resistance to high temperatures
and pressures generally associated with Shell & Tubes.
Moreover, the compact design of a single Alfa Laval Packinox
can replace several tubulars, thus enhancing the impact on
capex and opex by cutting installation costs and pressure
drop consumption.
Alfa Laval Packinox heat exchangers improve the overall economics
of greenfield units, and also serve as a low cost retrofitting
basis for debottlenecking existing units as Alfa Laval
Packinox allows higher duty with lower pressure drop. No
other change to the unit’s existing equipment (compressors,
heaters, etc.) is needed to obtain higher throughput and/or
higher H2 production.
As a result of general satisfaction with the performance of
Alfa Laval Packinox Standard Combined Feed/Effluent Heat
Exchangers in catalytic reforming, Alfa Laval Packinox is now
considered the industry standard for CRUs and is specified
by the main process licensors for both semi-regenerative and
CCR units.
Typical process conditions:
Flow: 5 000 to 70 000 bpd (with one exchanger)
Temperatures: from 80°C (cold end) to 530°C (hot end)
Hot approach: as low as 30°C or less
Operating pressure: 7 to 45 bars depending on process
ÄP in exchanger: 2 to 0.7 bar
