Columbia Southern MEE 6501 Unit VII Advance air Quality U6 Proposal

As a continuation of our course project due in Unit VII (A Permit by Rule (PBR) Evaluation for Painting Operation Facility), complete the next section—VOC Content Minus Water and Exempt Solvents—of your proposal by following the instructions carefully, and then submit your continued draft of your evaluation document into Blackboard for grading. Columbia Southern MEE 6501 Unit VII Advance air Quality U6 Proposal

  1. Closely read the required reading assignment from the textbook as well as the unit lesson in the study guide.
  2. Open your proposal draft from Unit V, and make any improvements to your draft, using your professor’s feedback from the Unit V Mini Project.
  3. Open the Unit VI Study Guide, read the Unit VI Lesson, and then review the calculations demonstrated and explained regarding VOC content minus water and exempt solvent calculations for our scenario. Be sure to use the scenario data instead of the data used in the study guide examples.
  4. Make your Unit VI work the fifth level 1 heading titled “VOC Content Minus Water and Exempt Solvents.” Describe the environmental, health, and safety (EHS) implications of the work system while pulling from the textbook as well as any other relevant sources that are presented in the unit lesson in the study guide. In your description of the EHS implications of the system, be sure to discuss the methods for sampling, quantitatively analyzing, and evaluating air quality.
  5. Perform and present (not hand-written, but neatly typed) the calculations for the following in this section of your project: (a) gallons of water in one gallon of coating, (b) gallons of exempt solvent (ES) in one gallon of coating, and (c) pounds of VOC in one gallon of coating (less the water and ES) per day. Determine if the work system is still going to need any administrative controls to keep it is compliance with the state requirements.

  6. In your abstract section (page 2 of the document), write one or two sentences that reflect your work for this unit. Remember that we are adding one sentence per unit to reflect our work as we go, with the final abstract length being about 8 to 10 sentences long.

Your narrative and calculations for operational air emission rates must be presented in at least 200 words (minimum). You are required to use at least one outside source, which may be your textbook. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying APA citations.

MEE 6501- General Consideration for Operation Sample Paper

Operational Air Emission Rates

Operational air emission rates refer to the frequency at which air pollutants are let out into the atmosphere in a measured period either daily, monthly or yearly in safe and controlled quantities (Omstedt, 1988). These air polluting substances are released through various activities and forms such as in our case the Painting Operation Facility which releases volatile organic compounds (VOC) through the painting process. Columbia Southern MEE 6501 Unit VII Advance air Quality U6 Proposal

The operational air emission rates are calculated by taking into account the Exempt Solvent (ES) content in the volatile organic compound (VOC). The indication of the amount of exempt solvent content enables one to calculate and compare with the maximum allowable hourly to annual safety emission rates (Code, 2009).

To calculate the VOC operational air emission rate of the Painting Operation Facility we shall make the following assumptions:

  1. A day takes 2 vehicles to be painted, both taking 5hours per day and in a week the facility operates 4 days
  2. The interior lining takes 10 gallons of paint per vehicle while the vehicle lining application takes 2 gallons per vehicle.

Calculation:

The maximum emission rate is calculated as = coating VOC content * max. hourly rate of used gallons

  • Daily gallons used for Interior lining = 10 x 2 vehicles = 20 gallons/day
  • Hourly gallons used for Interior lining = 20/5 = 4 gallons/hr
  • Daily gallons for Vehicle lining application = 2 x 2 vehicles = 4 gallons/day
  • Hourly gallons for Vehicle lining application = 4/5 = 0.8 gallons/hr

The coating content for internal VOC content by volume is 10/12 = 0.8333

Vehicle lining application VOC content by volume is 2/12 = 0.1667

Hence: Columbia Southern MEE 6501 Unit VII Advance air Quality U6 Proposal

The maximum emission rate of VOC content for the interior lining

=4*0.8333 = 3.3332gallons/hour

While the maximum emission rate of VOC content for vehicle lining

= 0.8*0.8333 = 0.66664 gallons/hour

The Potential to Emit on the other hand indicates the maximum limit an air-polluting source is allowed to emit in it is operational and/or physical model. This is usually calculated by estimating the hourly emission rate of the source while in continuous operation for 8760 hours per year (Wang, 2004).

Hence in our case, the PTE is calculated as:

PTE for interior lining = 3.3332gallons/hour x 8760 = 29198.832 gallons/year

PTE for vehicle lining application = 0.66664 gallons/hour x 8760 = 5839.7664 gallons/year

Operational Face and Filter Velocities

Volatile organic compounds (VOC) are gaseous air polluting products from various solid or liquid substances. VOCs are harmful and they adversely affect our environment, health, and safety in either short-term or long-term periods. In workplaces, the VOCs can be emitted from paints, varnishes, cleaning and disinfecting products among other sources. Columbia Southern MEE 6501 Unit VII Advance air Quality U6 Proposal

The health implications of VOCs include ear, nose and throat irritations, headaches and nausea, damage to the liver, kidney or the nervous system as well as cancer. Environmental effects of VOCs include the formation of GHG (greenhouse gases), acidic rain and damage of the ozone layer that leads to climate change hence affecting the safety and protection of the ecological wildlife and the future generation (Godish et al., 2014).
