Tube bundle, 900 mm nominal diameter of a
floating head condenser installed at Shell Petroleum Refinery
|
| The
barometric condenser
is employed as a reliable and economical means of condensing steam from
evaporators, vacuum crystallizers, calandria pans, vacuum systems and
many
other equipment.

There
are two kinds of barometric condensers: countercurrent spray type in which
steam flows upward against the water flow and parallel jet one in which
vapor flow in the same direction as water.
The former requires low water
flow rate and less pressure.
The second needs higher water pressure and higher flow
rate, but requires no pump for the air.

The
outstanding feature of the barometric condenser is that the cooling water
may be discharged through the tail pipe by gravity, without a pump.
It is a not flooding low cost device, easy to install, that
requires little space and low maintenance.
|
Surface
condensers
are used when vapors condensed should not enter into the cooling water
circuit, in order to recover them and avoid contamination of the cooling
water system.
Surface
cooling condensers
are normally used as pre, inter and post-condenses in vacuum systems of
oil refineries.
They may be fixed or
floating head according to the service. |
