This book discusses recent developments and future directions in the field of
membrane separation systems. It describes research needed to bring energy-saving
membrane separation processes to technical and commercial readiness for
commercial acceptance within the next 5 to 20 years. The assessment was conducted
by a group of six internationally known membrane separations experts
who examined the worldwide status of research in the seven major membrane
areas. This encompassed four mature technology areas: reverse osmosis, microfiltration,
ultrafiltration, and electrodialysis; two developing areas: gas separation
and pervaporation; and one emerging technology: facilitated transport.
Membrane based separation technology, a relative newcomer on the separation
scene, has demonstrated the potential of saving enormous amounts of energy
in the processing industries if substituted for conventional separation systems.
It has been estimated that over 1 quad annually, out of 2.6, can possibly be
saved in liquid-to-gas separations, alone, if membrane separation systems gain
wider acceptance. In recent years great strides have been made in the field and
even greater future energy savings should be available when these systems are
substituted for such conventional separation techniques as distillation, evaporation,
filtration, sedimentation, and absorption.
The book pays particular attention to identifying currently emerging innovative
processes, and to further improvements which could gain even wider acceptance
for the more mature membrane technologies. In all, 38 priority research
areas were selected and ranked in order of priority, according to their relevance,
likelihood of success, and overall impact. Rationale was presented for all the
final selections; and the study was peer reviewed by an additional ten experts.
The topics that were pointed out as having the greatest research emphasis are
pervaporation for organic-organic separations; gas separations; microfiltration;
an oxidant-resistant reverse osmosis membrane; and a fouling-resistant ultrafiltration
membrane.
