Tiivistelmä (eng): | Evaporation is one of the oldest and most important unit operations in the industrial sector. As it is also the most energy consuming area in any industry, research and development and improvements is a continuous process over the years. As also one type of evaporator, will be appropriate only for limited applications, there are numerous variations based on the scope of application which is very wide. Variations can be in design, material of construction, size, modularity, process placement, operating mode, arrangements etc. Many literatures and information are available detailing these various types, design and applications. But very few information is available comprehensively explaining the precise use of evaporations in each process with inlet and outlet concentration values. The main objective of this thesis work is, compilation of brief technical information on evaporator application in major processes and calculation of evaporation load to produce specific quantity of the final product in these industries. As sea water desalination is one of the niche application area for evaporators which is still surviving in spite of fierce competition from other technologies, a brief report is also presented on its market scope. As mechanical vapour recompression evaporation systems are one of the most energy efficient types, a simulation report using Aspen Plus version 8, is also presented for MVR type sea water desalination plant of capacity 1000 cu.m/day with thermal analysis of sensible heat savings in the process loop. Various configurations were tried with and without sensible heat recovery heat exchangers. It was found that recovering the heat from outgoing distillate and concentrate with heat exchangers in parallel configuration was the most efficient in reduction of external energy consumption, which was steam in this case. |
