Pakistan’s First Water Desalination-&-Power Plant

-

On the same day (Feb 11, 2008) when South Bound Lyari Expressway was inaugurated, another important project of Pakistan reached its opening milestone. This one is called the DHA Desalination and Power Plant. It is the first project of its kind in Pakistan which desalinates water from the Arabian Sea for human consumption as well as provides Electrical Power to the KESC Grid.

The Capacity:

The capacity of the Power plant is 94 MW (Mega Watts) and that of the desalination plant is 3 MIGD (Million Imperial Gallons per Day). Electrical Power generated here is supplied to the 132 KV (kilo-volt) KESC grid whereas the Desalinated Water is supplied to CBC/DHA for local distribution.
The fuel for the Power Plant is Natural Gas which will be provided by the Sui Southern Gas Company Limited (SSGCL) via 20″ diameter pipeline. The Electrical Power is generated by two turbines. One is Gas fired with the generation capacity of 67MW. The other is Steam fired with the generation capacity of 27 MW.

Who Did What:

The project is carried out by DHA Cogen Limited (DCL). It is a Public Limited Company which was incorporated in the city of Karachi on January 19, 2003. The company is a joint venture between Defence Housing Authority, Karachi (DHA) and Sacoden Investments, Singapore (SI). The contract for building the Power Plant was given to Siemens AG Germany (SAG) who also supplied the two turbines used in the plant. The Desalination Plant is built by Alfa Level, Copenhagen, Denmark (ALC) and the civil works is carried out by Siemens Pakistan (SPK).

Oil mist detectors

There are two methods of oil mist detection, Obscuration and Light Scatter . The earlier forms of oil mist detector used an obscuration type detector, the most well known type being the early Graviners. Schaller use obscuration in their Visatron range of OMDs. Light scatter is a modern method of oil mist detection used by QMI and the Latest Graviner Mk6 OBSCURATION The older type of obscuration type of detector consists of two parallel tubes of equal size, each having a photoelectric cell at one end which generates an electric current directly proportional to the intensity of the light falling on its surface. Lenses are fitted to seal the ends of each tube but allow light to pass. Two identical beams of light from a common lamp are reflected by mirrors to pass along the tubes onto the cells which are then in electrical balance. The samples drawn from the crankcase are drawn in turn along the m

Crankcase relief valve testing

FLAME ARRESTORS AND SHIELDING The intention of the requirement to shield the valve discharge was to reduce the possible danger to personnel from flame emission. However explosion testing has shown that whilst a flame arrestor will work satisfactorily when shielding is not fitted, when shielding is fitted, the energy from the discharge is focussed in one direction, and there will be an emission of flames during an explosion. The fitting of shielding also reduces the effective outflow area of a valve. Since July 2002 it has been a Lloyds Register rule requirement to fit flame arrestors and to test the relief valve with any proposed shielding to be fitted to the valve when installed on the engine. A test procedure for new crankcase relief valves has been developed over the past four years by MAN B&W, The Physical Test Institute in the Czech Republic , Hoerbiger, and various classification socie
