This
Volume covers the removal of dispersed liquid
droplets from gases under circumstances where
negligible quantities of insoluble solids are
present. The accent is on the use of demisters
for the chemical process industries although much
of the information is also relevant to gas oil
separators.

Volume
GC VII Part 1 Introduction.
This part gives a brief
description of the structure of the rest of the Manual
volume.
Volume
GC VII Part 2 State of the technology.
The operation and use of
different types of the demister are described. The devices
are grouped according to the collection mechanism employed
including gravity, inertia, centrifugal force, diffusion
and electrostatics. Devices described include gravity
separators, knitted mesh pads, wave plates, packed beds,
cyclones, candle demisters and wet electrostatic precipitators.
Multi-stage demisting installations, fouling, gas flow
distribution and liquid seals are covered. Also, practical
aspects of droplet formation are discussed.
Volume
GC VII Part 3 State of the science.
Models available for predicting
demister performance and operation are discussed. As
in Part 2, devices are grouped according to the collection
mechanism employed, and models for collection efficiency,
pressure drop and flooding and re-entrainment are included.
Also, models for droplet formation are described. The
use of computational fluid dynamics (CFD) for predicting
gas flows in demister vessels is also covered.
Volume
GC VII Part 4 Equipment
design and selection.
This part includes advice
on how to adequately define the demisting problem, select
possible solutions and size/design installations. It
is planned that this part will be expanded as design
procedures become available from the SPS demisting research
programmes.
