All About Air Pollution Control Systems



Air pollution is affecting human lives in multiple ways. With long-term health effects such as respiratory diseases, lung cancer, heart diseases, air pollution can also beget long-term damage to organs such as kidneys, nerves, and liver.

To deal with all such disastrous effects of air pollution, there’s a lot to learn for preserving human health and conserving our planet's habitat. According to WHO, there are around 7 million premature deaths every year due to industrial and household air pollution. Such facts are a sign for industries to maintain and install robust air pollution control systems in their plants or facilities to reduce the risk of pollution hazards. These steps can help in bringing down the emission levels of perilous exhausts, reduce the free outflow of particulate and vaporous pollutants in the atmosphere. 

Elements of air pollution control system

Systems for controlling air pollution can be installed in multiple ways by different industries, as per their preference. Let us understand what elements does a commonly installed primary corrosion-resistant ventilation system comprises of the following:

Duct System

An arrangement to supply, return, and exhaust air to and from the facility. The duct system is made up of hoses and tubes only. They’re efficient in maintaining indoor air quality and also filter out most pollutants from the exhausts. It’s one of the most critical and conventional systems employed by industries and is available in a variety of materials. However, polypropylene and polyvinyl chloride are the most preferred ones, as they can withstand even the corrosive air streams.

Fume & exhaust hoods

To maintain higher indoor air quality, fume and indoor hoods are durable ventilation alternatives. Fume hoods help limit the amount of exposure the plant’s staff have to toxic gases, vapors, and chemical fumes. Whereas, exhaust hoods assists in capturing emitted toxins. They’re also mostly made up of polypropylene and polyvinyl chloride.

Exhaust blowers and fans

Plants aiming at eliminating harmful vapours, particulate matter, smoke, and unwanted odours tend to employ exhaust fans or blowers either on the roof or inside the industrial unit. These units ventilate horizontally or vertically by a direct-driven, belt-driven, or inline fan. The fans are made up of thermoplastic materials which are used in galvanizing and electroplating processes. 

Wet scrubbers
These scrubbers are utilized to clean the air emitting from the facility. They are large control units that are specifically employed for eradicating dangerous air pollutants. One of the most common types is wet-packed tower scrubber, which is used in industries to continuously re-circulate the scrubbing solution to shed odorous acids and vapours.

When installing an air pollution control system, you must initially assess the generation patterns of the dust and fumes of the plant. The majority of air pollutants can be eliminated by efficiently making a few tweaks to plant machinery. But, if the plant emits an immensely noxious gas, then proper care must be taken to effectively capture, extract, and dispose or recycle the air.

What are Bi-Drum Boilers? How Do They Work?

Image
Bi-drum boilers are used for purposes of power generation and as process steam generators. This type of boiler is used up to 100MW for generating power. Bi-drum boilers are non-reheat units which are getting wiped out due to high heat rate of the plant. These boilers are used for generating high steam pressure which is used for power generation owing to their ability to accommodate high load of fluctuation and respond to load changes with more agility compared a single drum boiler. The two drums in the bi-drum boiler are connected using a large number of convective heat transfer tubes known as bank tubes or boiler bank tubes. These tubes are about one thousand in number. The bank tubes and the drum at the bottom that contains water will have a water level that will be up to the normal working level of water in the upper drum. The water availability in the bi-drum boiler makes it very adoptable for large load changes. Flue gases enter the bank tubes which are placed towards t...

How Do Electrostatic Precipitators Work?

Image
Reducing air pollutants is vital for human health and the health of the environment. Poor air quality has harmful effects on human health, particularly the respiratory and cardiovascular systems. Pollutants also damage plants and buildings, and smoke or haze can reduce visibility. Industries are largely responsible for causing pollution. They are also the ones who have access to a number of pollution control devices that absorb, filter, dilute, and disperse pollutants. One such device for pollution control is the electrostatic precipitator. This device works by removing particles and smoke from a gas stream using an electrostatic charge. Dust particles travel past wires that have a high direct current (DC) voltage applied, which ionises the surrounding gas. This corona discharge causes the particles to pick up a small electrostatic charge, without impeding the gas flow. Originally designed for recovery of valuable industrial-process materials, electrostatic precipitators are used a...

Quick overview of the Import & Export of Chemicals in India

Image
The chemical industry in India offers building blocks and essential raw materials for numerous industries such as paints, paper, textiles, pharmaceuticals, agrochemicals, soap, and detergents, etc. Let’s go through a few statistics of the chemical industry: The chemical industry in India is ranked 4th in Asia and 6th in the world. The global chemical industry is expected to be worth $4.7 trillion. The chemical companies in India contributes 3.4% to the global chemical industry. As of 2018, the chemical industry (including pharmaceuticals and fertilizers) stood at $163 billion. The Chemical sector in India is expected to grow at 9% per annum to reach $304 Bn by FY 2025. The expansion is anticipated to be pushed by rising demand in end-use segments for Specialty Chemicals and also for petrochemical intermediates. In 2015-16, the Chemical and Chemical Products sector accounted for 2.39percent of the GVA, compared to 2.23percent in 2014-15.18 Note: With India possessing a l...
