Spray flash evaporator for low-temperature saline water desalination application

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 ...

Danfoss, Nordborg, Denmark - Case Study

ELTS 1500 Capacity of 1500 l/h This plant treats oil emulsion from the metal working industry. The feeding water has a content of oil of 5-10%. Through a 2 step evaporator the liquid is being reduced, resulting in a content of oil of 90-95%, which is high enough for being used as fuel. The 2 steps consist of one natural circulation evaporator and one flash evaporator. The heat for ...

Enhancement of the performance of the vapour compression plant

The objective of the present work is to study the performance of ejector vapour compression desalination plant with water spray on horizontal tube bundles. The effects of the operating conditions and the ejector geometry on the total distilled collected water are studied. The amount of evaporation rate due the flash evaporation is calculated by applying the mass and energy of the sprayed water ...

Experimental studies on a desalination plant using ocean temperature difference

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 ...

Energy and exergy analyses of the drying step of a copper-chlorine thermochemical cycle for hydrogen production

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 ...

Thermocline-driven desalination: the technology and its potential

Seawater desalination technology is emerging as freshwater requirements are alarmingly increasing all over the world. Conventional technologies such as reverse osmosis and multistage flash evaporation have their limitations, such as chemical treatment and scaling. Low-Temperature Thermal Desalination (LTTD) is an attractive technology with vast potential. It makes use of the ocean temperature ...

Operating experience of desalination unit coupled to primary coolant system of CIRUS

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 ...

Advances in desalination technology

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 ...

Case study - Tin plating wastewater treatment

The Client The Client is a steel industry based in the Middle East producing tinplates for food cans. Tinplates provide excellent corrosion resistance and are produced starting from cast iron by several steps. Cast iron is first rolled to get thickness in the range of 0.2 – 0.3 mm than it is electroplated from aqueous acid solutions at a temperature around 60°C. The plating bath ...

Selection and economical evaluation of solar desalination technologies via DesalSolar software

Worldwide projection indicated that in 2020 the situation of water resources in Iran reach to scarcity. Besides, global warming and energy crisis have forced countries to use renewable energy resources. Solar desalination technologies particularly in remote area of Iran could be a method to emancipate from this crisis. In this paper, all kind of desalination technologies were reviewed. Then, ...
