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 ...
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 ...
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 ...
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 ...
A thermo–economic optimisation analysis is presented yielding simple algebraic formulae for estimating the optimum number of desalination stages, condensing unit and brine heater size with operating temperatures for distilled water production. The P1–P2 method is used in the present study, together with the thermo–economic analyses of desalination equipments.Keywords: thermoeconomics, ...
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 ...
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 ...
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 ...
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 ...
This report describes how treatment of landfill leachate by means of forced circulation vacuum evaporation provided: an environmental benefit from use of biogas as power supply a big saving in disposal cost due to waste volume reduction a return on investment of less than two years Introduction Solid Waste Management in Greece has been remarkably upgraded during the last fifteen years, ...
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 ...
As demand for fresh water increases, communities look to the sea and to previously unusable aquifers With the world’s population consuming water in record amounts and water scarcity causing a host of geopolitical and humanitarian problems, technology can be harnessed to help meet the demand. One increasingly important solution to freshwater scarcity is treating saline water through a ...
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, ...
The Facility Eagle-Picher Industries has an 8-acre hazardous waste surface impoundment pond at its Electro-Optics Division plant in Quapaw, Oklahoma. The Problem By the time Eagle-Picher contacted Aqua-Chem ICD, the impoundment pond had been in use for more than 20 years and contained more than 5 million gallons. Environmental regulation required the plant to install a double liner in the ...
