While working in an industrial setting, there are bound to different types of chemicals and processes giving different odour. Some of this odour can be quite harmful to those working there and can endanger their lives. Not only do some of these odours carry poisonous gases, but they also have the power to have physical and mental consequences on the health of the workers.
Odours are, anyway, not a pleasant and welcoming smell. Even in our own houses, we get annoyed when we get the whiff of an odour from somewhere and immediately put room fresheners and sprays to eliminate the smell. However, in an industrial setting, you cannot eliminate the odour of such chemicals through a mere freshener or spray. So instead, industrial environments make use of odour scrubber, both biological and chemical.
These odour scrubbers are used to remove poisonous gases like chlorine, hydrochloric acid, and sulfur dioxide emitted by the chemical plants installed in industrial settings. This article will tell you how the odour scrubbers are operated to remove the odour and poisonous gases.
Operation Of Odour Scrubber
These wet odour scrubbers are applied by spraying on an incoming harmful gas stream with the help of a scrubbing solution that contains a neutralizing chemical that eliminated the harmful gas. How effective the scrubber is in eliminating the dangerous gas depends on the quantity and concentration of the neutralizing scrubbing chemical, which keeps reducing as the process goes on. Hence, to ensure that the odour scrubber effectively does its job, it is imperative to check the concentration of the scrubbing chemical and maintain it. This can be effectively achieved by keeping a check on the pH and conductivity of the scrubber.
To control and maintain the scrubbing chemical’s concentration, the following methods can be employed:
- Batch Scrubbing: This type of Scrubbing usually begins with a heavy concentration of the scrubbing chemical, which is allowed to reach near the stage of depletion, followed by blowdown. After that, it is replenished with a fresher scrubbing chemical.
- Continuous Scrubbing: in the case of constant Scrubbing, the concentration of the scrubbing chemical in the odour scrubber will depend upon the gases on which it is being applied and how they are being controlled.
Control Of Ph
Measurement of Ph is imperative when deciding to bring an odour scrubber that will be used for continuous Scrubbing. Excess of basic scrubbing chemicals is required in the odour scrubber for scrubbing acidic gases like hydrochloric acid. In such cases, pH control can be put to use to control Scrubbing and ensure that there are very few consequences resulting from the scrubber by-products.
This control, known as the conductivity control, is best suited for batch scrubbing, as explained above. In batch scrubbing, the conductivity control is used to measure the concentration and alert the operator the check the attention.
In the case of continuous Scrubbing, control conductivity is usually used to start a blowdown to eliminate the chances of high dissolved solids build up.
We believe, now you have been quite familiar with the uses of Odour Scrubbers. Once you purchase odour scrubbers, you can be assured that the items will reduce odours from the onion and meat cooking processes that you do at your place quite often.
These scrubbers help in reducing the pollutants from any stored wastewater. Moreover, the best part about these chemicals is that they help reduce nitrogen-related compounds from the environment. Considering these vital factors, consider
