A heat exchanger maker based in the United Kingdom supplied a corrugated shell-and-tube heat exchanger for a compressor installation that maintains natural gas supply pressure to a gas turbine at a Manchester, England, paper mill.
HRS Heat Exchangers Ltd., London, a heat transfer specialist
for process industries, has supplied Gas Compressors Ltd., Kent, England, with
an HRS K37 multi-tube corrugated shell-and-tube heat exchanger for a compressor
installation that maintains natural gas supply pressure to a gas turbine at a
Manchester, England, paper mill.
The 13' long heat exchanger cools the
gas supply after compression, which is required to maintain feed pressure to
the turbine in periods of high demand to ensure uninterrupted operation. The
heat exchanger condenses out any water vapor present in the gas composition.
The corrugated design achieves the
required heat transfer to reduce the gas temperature from 194°F (90°C) to 113°F
(45°C) with a very low pressure loss. The corrugated tube enables the heat
exchanger to be considerably smaller than a comparable smooth-tube unit,
according to the company
“This is a very demanding
application,” says Priya Murray, HRS’s technical manager. “Good heat transfer
is normally only achieved by high gas velocity and a corresponding high
pressure loss that reduces the efficiency of the whole installation. Our
corrugated tube design reduces pressure loss to deliver the efficiency required
and occupies less space.”
