Understanding cooling towers

NEED

Very high cost of cooling water e.g. RS. 2 to 6 /m3 of treated water doesn%u2019t permit plant operators to operate in an open loop cycle in the cooling water circuit. Hence, the closed loop cycle is selected in almost all process plants all over the world.

In a closed loop cycle, the power consumption required for cooling the water (in cooling tower fans only while considering pumping cost as almost same in both the cases) varies from 0.02 to 0.04 kWh/m3 of water so, the cost of cooling of water ranges from RS. 0.02 to 0.20/m3 in Indian conditions. This is almost 100 times lesser than the cost of cooling water in a once through cycle. That%u2019s why it is customary to use cooling towers in any chemical process industry, especially in hot climatic conditions.

Ammonia: Steps Ahead
technologist | 28 Jun, 2007, 23:06 | Technology | (186 Reads)
Steam reforming of hydrocarbons for ammonia production was introduced in 1930. Since then, the technology has experienced revolutionary changes in its energy consumption patterns. Ranging from an early level of 20 Gcal/tonne (79.4 MBtu/tonne) to about 7 Gcal/tonne (27.8 MBtu/tonne) in the last decade of the 20th century. The energy intensive nature of the process is the key driving force for improving the technology and reducing the overall cost of manufacturing.
Looking further ahead, we'll review some potentially significant developments and concepts that may impact the manner in which ammonia is produced. Some of these manufacturing routes are being tested or employed at a few plants around the world, but have yet to be fully developed into commercial processes. We'll also review more traditional approaches to ammonia manufacturing along the way.

World Environment Day - Some Pledges
technologist | 05 Jun, 2007, 23:20 | General | (146 Reads)
My Company’s Message on World Environment Day

1. I will boil only the water I need, rather than filling the kettle every time.
If you boil a full kettle three times a day you’ll raise carbon dioxide emissions by 52kg a year. It takes two trees to absorb that amount. If you only boil the water you need each time, you’ll save energy and reduce your carbon dioxide emissions by more than 7kg a year.

· Carbon dioxide is a greenhouse gas, which contributes to climate change. We need to reduce the amount of carbon dioxide we release to limit the effects of climate change.

· Although trees can be planted to absorb some of this carbon dioxide, we really need to use up less energy in the first place.
2. I will replace two light bulbs in my house with energy saving versions.
Over one year, it would take 13 trees to absorb the 40kg of carbon dioxide you would have emitted into the air.

· The release of carbon dioxide into the atmosphere, caused by the burning of fossil fuels, contributes to climate change. We are experiencing more floods and droughts, and wildlife and plants are also affected.

· Countries that have ratified the Kyoto Protocol must reduce their carbon dioxide emissions.

· Reducing the amount of electricity we use will mean that less fuel is burned for the generators that supply it. Doing this will also save you money.
