N2 - Product separation and purification is costly but crucial
step in chemical production concepts. Lots of information
is needed in designing these systems, this is not however
always available for first conceptual design. The main
focus in this project was on developing competence and
readiness to conduct reliably but rapidly conceptual
techno-economic assessments of (bio)chemical production
processes. The idea was to develop a rapid method and a
generic "short-cut" model for evaluation of different
alternative separation systems mainly for solid-liquid
and liquid-liquid systems, but also for gas-liquid and
gas-solid systems. The model was created with Balasr
simulation software linked with MS Excel. The description
of the model is presented in PowerPoint slides, ChemSep -
report slides. This document, instead, acts as a theory
source for the use of the model. In this document, the
classification of separation processes into heterogeneous
and homogeneous separation processes is presented,
different unit operations of separation are shortly
described and the possible application examples are
listed. Heterogeneous separation processes that are
described in detail include decantation, hydrocyclones,
settling, sedimentation, flotation, centrifugal
separation, filtration, wet scrubbers, leaching/washing
and solid drying. Homogeneous separation processes that
are described in detail include flash vaporization,
distillation, drying of solutions, evaporation,
crystallization and membrane technology. The operational
principles, equipment types, selection of appropriate
equipment and applications for each above mentioned
separation process are described. The theory of the
calculation of mass and energy balance in each unit
operation are excluded. It can easily be found in the
literature. Also, a short chapter of criteria affecting
the selection of a suitable separation process for the
mixture in question is presented.
