In processes of evaporation,
distillation or drying, steam is used at
different pressure and temperature levels.
Such processes are found in the chemical,
pulp/paper, fiber and several similar
industries. These industries use large
volumes of boiler generated steam, of which,
very little is recovered after use because
the pressure has been reduced to near
atmospheric conditions. As a result, this
"unusable" steam is vented to the
environment while fresh steam is generated.
A reversal of this cycle could be a
potential source of cost savings in an era
when the cost for generating energy is on
the rise and represents a major portion of
the cost of the raw materials. The
technology is available today to prevent
such loss of resources by recompressing the
low pressure steam to a usable pressure for
reinjection into the process stream. Mycom
has developed, designed and installed two
large MVR systems using screw compressors:
one for a brewery and the other for a
whiskey plant. This paper discusses the system aspects
that presented challenges to Mycom. The
economic benefits being realized will be
discussed.
