Abstract

VOCs do have effects and adverse implications to EHS, identifying this therefore does help in controlling and knowing how to prevent these issues. It is also important to know how to calculate face and filter velocities in the process of knowing how to reduce these effects.

Volatile organic compounds (VOCs) do have adverse effects to the Environmental, Health and Safety (EHS). Some of the environmental implications that VOCs have include pollution, pollution effects are usually said to be directly related with the same effects that the same do end up having and causing health issues (Hasan et al., 2017). Some of the VOCs that do have implications to the EHS include Sulphur dioxide (SO2), chloride (Cl2), nitrogen dioxide (NO2), Ammonia (NH3), Hydrogen fluoride (HF) and many others. When these compounds are released to the environment in a bad and careless way, then this may end up having huge implications to the EHS.

Pollution impacts that the VOCs have to the environment is the fact that when these compounds are released to the atmosphere, they in most cases end up leading to having acidic depositions which usually ends up bringing about acidic rain which have huge implications to both human and plants. Compound or chemicals such as fluoride (F) do have adverse effects to animal’s health in that, this usually ends up disrupting the metabolism of Calcium (Ca) in both the rumen ad the simple stomach (Antonelli et al., 2020). The volatile organic compounds (VOCs) also do have safety health related issues that they can and do cause to human beings, in as much as most VOCs are usually considered to be having specific health risks, there are certain common short term safety and health effects that all these VOCs do have they include, dizziness, eye irritation, headaches and even drowsiness. Long term effects include damage to the liver, loss of coordination and kidney damage.

The below are the calculations of the face velocity and filter velocity of the given scenaros.

Face velocity

Face velocity (in ft/min) = flow rate / intake area

4240 ft3/min / 28.26 ft2

=150.04 ft

Filter velocity

Filter velocity (in ft/min) = flow rate / total filter area

4240 ft3/min / 40.0 ft2

106.0 ft/min
