Air Pollution Control System

An air pollution control system plays a crucial role in reducing the risk of unexpected system failures and provides early warnings of potential issues, thereby avoiding unnecessary plant shutdowns and expensive regulatory penalties.

The first division between continents was made by ancient Greek navigators, who named them 'landmass, terra firma'.

Generally classified by convention rather than any strict criteria, nowadays seven regions are regarded as continents from a geopolitical point of view.

North America has five time zones and it is the only continent with every type of climate.

North America was named after the explorer Amerigo Vespucci and is also known as the 'New World'.

The world's largest sugar exporter among the seven continents - Cuba - also called the 'sugar bowl of the world' is located here.

Principles of APCS
Efficiency of filtering system
Transport air & entrained contaminant with adequate velocity
Capture contaminant with adequate velocity
Enclose source as completely as practicable
Function of APCS
Monitor the air or receive complaint
Verify source compliance
Verify Source Emission
Control Source
Develop Plan
Identify Problem

Benefits

Record keeping requirements help in management review & operating trends
Avoids unnecessary plant shutdown and costly enforcement
Lessens possibility of sudden system failure
Early indication of impending problem
Ensure continued performance of air pollution control system

Air Pollution Control System System

Australia is the world's smallest continent and is also known as an 'island continent' as it is surrounded by water on all sides.
It includes 14 countries and it is the least populated continent.

Its name comes from the Latin word 'australis' meaning 'southern' because it lies entirely on the south of the equator.

Function
Stack

To discharge/dispersed the clean air to the environment

Exhaust Fan

To create airflow in the system and supply required static pressure

Air Cleaner

To remove contaminants from the air stream

Ducts

To transport air and entrained contaminants within the system

Hood-To collect

receives or contain the emitted contaminants

Equipment

Of the seven continents of the world, Africa is the second largest.

Africa comprises 54 countries and it is the hottest continent.

The equator passes through the middle of Africa and it receives direct sunlight throughout the year.

The world gets 66% of its chocolate, 50% of the gold and 95% of the diamonds from Africa.

Types of Air Pollutants

Asia is the world's largest continent of the seven continents in size, as it covers one-third of the earth's surface.

It includes 50 countries, and it is the most populated continent, 60% of the total population of the Earth lives here.

The roots of pollutants

Europe is separated from Asia by the Ural mountains and the Caspian Sea.

It is surrounded by water on three sides: Mediterranean Sea in the south, Atlantic Ocean in the west, and the Arctic Ocean in the north.

Three-fourth of the world's potatoes grow in Europe.
