The heat exchanger is a device that allows heat from one fluid (liquid or gas) to be
transferred to
a second fluid (another liquid or gas) without the two fluids mixing or coming into
direct contact.
In general, as the name of the heat exchanger is clear, heat exchangers are responsible
for
exchanging heat between two fluids. Heat exchangers have many applications in various
industries.
Heat exchangers are used in both cooling and heating processes. Heat exchangers can be
of parallel
flow, cross flow, or counter flow type. In parallel flow heat exchangers, two fluids
enter and exit
in the same direction. In cross-flow heat exchangers, two fluids are moving
perpendicularly to
each other. In counter-flow heat exchangers, two fluids are moving oppositely. Counter
flow heat
exchangers are more effective than other heat exchangers
One of the most used heat exchangers in the oil and gas industry is the
shell and tube.
It is one of the most widely used heat exchangers in various industries.
Shell and tube heat
exchangers consist of many small tubes inside a cylindrical shell. The tubes
are placed inside the
cylinder using a tube bundle, which can have fixed tube plates (permanently
fixed to the body).
These types of exchangers are suitable for high temperatures and pressures.
Two fluid flows with
different initial temperatures enter the exchanger; one passes inside the
tubes, and the other passes
through the shell (outside the tubes).
Heat transfer takes place between two fluids through the walls of the tubes.
An exchanger is called
a single-phase exchanger in which a fluid (liquid or gas) flows on both
sides (inside the shell and
tube).
