flash evaporator Articles

A new spray-type flash evaporator is suggested for the application of saline water desalination. The flash evaporator is 1000 mm in height and 1200 mm in diameter, with a water injection arrangement inside. The evaporator design is based on experiments conducted at vacuum pressures between 10 and 18 mm of Hg, and at saline feed water temperatures between 26?C and 32?C. The saline water is ...

CIRUS is a 40 MWth, light water cooled research reactor located at Trombay, Mumbai. The reactor was shut down in 1997 for refurbishment and restarted in 2003. At Bhabha Atomic Research Centre R&D activities on desalination have led to development of desalination technologies based on Multistage Flash (MSF) evaporation, Reverse Osmosis (RO) and Low Temperature Evaporation (LTE). Based on LTE, a 30 ...

A desalination plant of 100 m? per day capacity utilising the thermocline across the ocean depth was commissioned in Kavaratti Island, India during May 2005 and it is operational till date. The flash evaporation of warm surface seawater is followed by the condensation of vapour utilising deep-sea cold water. The plant draws water from 330 m depth at 12?C. A 1 MLD capacity floating plant was ...

Hydrogen can be produced by decomposing water, through thermochemical cycles, in an environmentally benign manner using nuclear energy. The copper-chlorine (Cu-Cl) cycle is one of the most promising low-temperature thermochemical cycles and involves five main steps: HCl (g) production; oxygen production; copper (Cu) production; drying; hydrogen production. In this study, energy and exergy ...

The energy and exergy balance methods were performed on two advanced transcritical CO2 air conditioning cycles presented in the literature. In addition to the basic transcritical CO2 air conditioning cycle which has five main components, compressor, gas cooler, evaporator, expansion valve and internal heat exchanger, two advanced cycles are investigated; both have two-stage compressor (low stage ...

Open cooling towers are susceptible to freezing due to their inherent nature of operation, heat rejection by evaporation. As a result, ice formation becomes a subject of management, not elimination. Several design considerations should be made to minimize the time and effort spent on ice management. Take a look at our latest e-flash,  ...

Seawater desalination has been the cornerstone of the Middle East's water supply strategy since the mid-1950s, and most of the installed desalination capacity is still provided by multistage flash evaporators. But, desalination is changing. In fact, the term "desalination" is no longer limited to seawater applications; desalination technologies are now routinely employed to desalinate brackish ...
