Abstract

Abstract- Water is the
most important chemical component on earth. Seawater distillation processes
have a considerable promise as a technique suitable for producing large scale
quantities of potable water from the seawater. It involves a broad range of
technologies that yield access to marginal sources of water such as seawater,
brackish ground- and surface water, and wastewater. Given the reduction in
access to fresh water in recent decades and the uncertainty in availability
effected by climate change, desalination is critical for ensuring the future of
humanity. Multieffect distillation employs the same principles of multi-stage
flash distillation but contrary to it, it occurs in a series of vessels
(effects) and uses the principles of evaporation and condensation at reduced
ambient pressure. A dual-purpose desalination plant is a process that produces
both power and desalted water with the optimum use of thermal energy in
producing the two products. It offers a considerable saving in energy usage.
The present paper focuses on the modelling and thermodynamic analysis of the "Multi-Effect
Distillation" (MED) desalination installed in combined cycle power plant.
The expected performance characteristics of the designed MED desalination plant
are determined.

Performance Analysis of Combined Cycle Power Plant with Multi-Effect Distillation (MED) Desalination Process

Abstract

Water is the most important
substance on earth. Seawater distillation processes have a considerable
technique suitable for producing large scale quantities of potable water.  This process involves a wide range of
technologies that yield access to different sources of water such as seawater,
ground and surface water, and wastewater. Because of the reduction in access to
fresh water in recent decades and the uncertainty in availability effected by
climate change, desalination is the critical process that ensure the future of
humanity for fresh water requirement. Multi effect distillation process employs
the same principles with multi-stage flash distillation but in contrasts, it
occurs in a series of vessels (effects) and uses the principles of evaporation
and condensation at reduced ambient pressure. A dual-purpose desalination plant
has a process that produces both power and fresh water using optimum thermal
energy. It offers a considerable saving in energy usage. This paper focuses on
the modelling and thermodynamic analysis of the "Multi-Effect
Distillation" (MED) desalination installed in combined cycle power plant
and moreover the expected performance characteristics of the designed MED
desalination plant has been determined.
