Modelling Of Multi-Stage Flash Process for the Production of Potable Water from Seawater

Nowadays people are moving towards renewable source to ensure the sustainable development. Many new green technologies have been introduce in order to sustain the development had been done by human. There are a few method of desalination that is multi stage flash desalination, multiple effect distillation, and reverse osmosis. In this paper, we have discussed one of method to produce potable water from sea water, which is multistage flash desalination. The main focus in this paper is the modelling of multistage flash desalination process. This is because MSF is applied in real world compare to other type of desalination. Many papers had been published for MSF in the Middles East but none had been done for South East Asia. This paper is focused on environment in Malaysia, using the characteristic of the Malaysia seawater at different temperature, pressure and salinity. Moving on we have study the market price of water in Malaysia and the price for desalination water. After that we had develop the simulation of multistage flash desalination using mathematical method with the aid of Microsoft Excel, MATLAB. We started the modelling by developing a mathematical method. Next we set the parameters and run the modelling. The total distillate yield is 1653m3 /hr that are 16.53% of the initial water intake. In the final part we had discuss the thing that can be improve this model.
