Which of the following can be used for controlling Gaseous Air Pollutant?

Which of the following can be used for controlling Gaseous Air Pollutant? Correct Answer Absorption

The correct answer is Absorption.

 Key Points

  • Absorption is a physical or chemical process of removing a pollutant from a gas phase media by dissolving the pollutant into a solvent media.
  • Absorption involves the transfer of a gaseous pollutant from the air into a contacting liquid, such as water.
  • The most common form of absorption is wet scrubbing.
  • A wet scrubber is the generic name of a control device that uses the process of absorption to separate the pollutant from a gas stream.

 Important Points

  • Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials.
  • Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities.
  • An electrostatic precipitator (ESP) is a filterless device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.

In the graph below, the concentration of a particular pollutant in a lake is plotted over (alternate) days of a month in winter (average temperature 10 °C) and a month in summer (average temperature 30 °C) Consider the following statements based on the data shown above: i) Over the given months, the difference between the maximum and the minimum pollutant concentrations is the same in both winter and summer. ii) There are at least four days in the winter month such that the pollutant concentration on those days are within 1 ppm of the pollutant concentrations on the corresponding days in the winter month. Which one of the following options is correct?
A pollutant P degrades according to first order kinetics. An aqueous stream containing P at 2 kmole/m3 and volumetric flow rate 1 m3/h requires a mixed flow reactor of volume V to bring down the pollutant level to 0.5 kmole/m3. The inlet concentration of the pollutant is now doubled and the volumetric flow rate is tripled. If the pollutant level is to be brought down to the same level of 0.5 kmole/m3, the volume of the mixed flow reactor should be increased by a factor of
In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: Air conditioning is the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments.  B: Electric refrigerant-based AC units range from small units that can cool a small bedroom, which can be carried by a single adult, to massive units installed on the roof of office towers that can cool an entire building. C: Air conditioners often use a fan to distribute the conditioned air to an enclosed space such as a building or a car to improve thermal comfort and indoor air quality.  D: This process is most commonly used to achieve a more comfortable interior environment, typically for humans and other animals.
