Salt water is pumped through a very fine membrane which does not allow the salt to pass through (osmosis). Only part of the water is "desalinated". The rest, with all the salt, is usually pumped back into the ocean, at some distance away from the plant.
Cost of course depends on capacity and desalination method. Shoaiba Desalination Plant, Saudi Arabia, uses MSF Flash technology with a total output capcity of 128 million gallons per day. Cost 1.6 billion $US.
Multi-stage Flash (MSF) Desalination
to create vacuum for decreasing the boiling point. it works the base of converging-diverging procedure.
Light Diesel Oil is used initially to ignite the coal in the boilers
Power generation plants typically require mechanical and electrical engineers as a majority of the workforce; however there are a few areas that a chemical engineer can get involved in. Any treatment processes within the plant, such as air, water, etc. can be done by a chemical engineer. If the power plant produces chemical wastes, such as tritium in a nuclear power plant, this isotope has to be removed in a process containing distillation columns and other chemical engineering processes, making chemical engineers ideal for this position. Some chemical engineers can work within risk assessment and can do work to determine risks within the plant and how best to prevent them.
a pumping plant because a desalination plant costs alot and they produce brine
It is due to the amount of energy needed to run a desalination plant, as well as the fines that have to be paid due to the amount of air pollution a desalination plant gives out.
how to design a desalination plant of 2000 tonnes per day production of distillate ,the desalination type of evaporation multi stage ,,with material balance,?
Desalination has very high energy requirements and since most countries with desalination plants do not have nuclear power, it results in the burning of lots of more coal. Additionally, the methods by which salt is removed from water create a resulting "salt-slurry" which is ejected as waste in to the original saltwater body. This salt-slurry makes the area around the desalination plant poisonous for the local sea-life.However, in almost every case, the positives of desalination outweigh these negatives.
The government of Saudi Arabia has just authorized the construction of a new seawater desalination plant.
