Which of the following fluid is used in web scrubbers? Explanation: Apart from lime, K2CO3, a slurry of MnO and MgO and water can be used in Web scrubber.

Which chemical is used in wet scrubber?

Caustic solution (sodium hydroxide, NaOH) is the most common scrubbing liquid used for acid-gas control (e.g., HCl, SO 2, or both), though sodium carbonate (Na 2CO 3) and calcium hydroxide (slaked lime, Ca[OH] 2) are also used.

What is used for scrubber?

Scrubbers are one of the primary devices that control gaseous emissions, especially acid gases. Scrubbers can also be used for heat recovery from hot gases by flue-gas condensation. They are also used for the high flows in solar, PV, or LED processes.

What are wet scrubbers used for?

Wet scrubbers are a special device used to remove a variety of pollutants from exhaust gas from furnaces or other devices. These devices use a scrubbing liquid to remove the pollutants. The exhaust gas is moved through the scrubbing liquid (usually through a chamber) and the liquid is misted through the gas.

What is a scrubbing solution?

A colloquial term for a skin cleanser for the removal of debris, dirt, microorganisms, oils, and scales from the skin of a patient before incision or instrumentation.

What removes dry scrubbers?

Dry scrubbing systems are used to remove acid gases (such as SO2 and HCl) primarily from combustion sources. Dry scrubbing systems consist of two main sections or devices: the scrubber and the scrubber media. Dry scrubbers spray very fine absorbents into a vessel where they combine with flue gases.

Which of the following equipment is installed to minimize pollution?

Electrostatic precipitators device that removes suspended dust particles from a gas or exhaust by applying a high-voltage electrostatic charge and collecting the particles on charged plates and used to reduce air pollution due to smoke in power plants.

How does a wet gas scrubber work?

In wet scrubbing processes, liquid or solid particles are removed from a gas stream by transferring them to a liquid. The liquid most commonly used is water. A wet scrubber’s particulate collection efficiency is directly related to the amount of energy expended in contacting the gas stream with the scrubber liquid.

How does a wet air scrubber work?

Wet scrubbers work by absorbing pollutants with water or a water-based solvent. In the wet scrubber, the contaminated gas enters at the bottom and passes upward through the packed bed and downward-flowing solvent sprays.

What are fabric filters?

A fabric filter, sometimes referred to as a baghouse, utilizes fabric filtration to remove particles from the contaminated gas stream by depositing the particles on fabric material.

How does gas scrubber work?

The Gas Scrubber removes traces of liquid droplets from gas streams to protect downstream equipment from damage and failure. It is typically used upstream of gas treating equipment that contains dry desiccants or mechanical equipment such as compressors.

How do you make a air pollution catcher?

  1. To make two air pollution catchers, you will need: …
  2. Mark the location you plan to hang your catcher on each plate. …
  3. Next, carefully apply a thin coat of petroleum jelly to one side of each paper plate.
  4. Place catchers in different locations outside your home, like one in the front yard and the other in the back yard.

How do you scrub chlorine gas?

Sodium hydroxide (caustic soda) is normally used in the absorption of chlorine containing gases. When chlorine reacts with the caustic salt is formed.

How does a bag filter work?

The Bag Filter separates dust from the exhaust gas by collecting them with the filter media. The dust is accumulated on the surface of filter media. And the filter media is cleaned by reverse airflow called backwashing (pulse-jet). The Bag Filter has a selection of filter media.

What is a bag filter system?

A baghouse, also known as a baghouse filter, bag filter, or fabric filter is an air pollution control device and dust collector that removes particulates or gas released from commercial processes out of the air.

How do you scrub biogas?

Biogas Scrubbing begins with the capture of biogas as a result of anaerobic digestion. Hydrogen Sulfide (H2S) is then removed by injecting atmospheric air into the scrubber tank, which allows bacteria to naturally oxidise the compound to sulfate and elemental sulfur.

How do you clean up an oil spill science project?

Drop a small amount of oil onto the water. The oil will float on top of the water. Even if you shake the container ( cover it first ) the oil and water will separate again. Use a cotton bud to move the oil around surface of the water.

How do you make a model for science?

What Makes a Good Scientific Model?
  1. based on reliable observations.
  2. able to explain the characteristics of the observations used to formulate it.
  3. predictive.
  4. able to explain phenomena that were not used to develop the model.
  5. able to be refined when new, credible, conflicting observations arise.
