Modeling Tip
TANKS in AERMOD
Emissions from tanks can be successfully modeled in the US EPA AERMOD model, but the approach taken to defining the source will depend on the type of tank. In this modeling tip, we will consider two different kinds of tanks; fixed roof and floating roof tanks.
Fixed Roof Tanks
Fixed roof tanks, as the name suggests, have roofs which are fixed at the top and do not move depending on the contents of the tank. There will be a vent on the roof, typically in the center, from which built up vapors can escape.
Floating Roof Tanks
Floating roof tanks have roofs which move with the level of the stored liquid to stop the build up of vapors. These kinds of tanks are typically used for the storage of liquids with low flash points. Emissions typically escape from around the sides of the roof.
It is also possible to have internal floating roof tanks, which have a floating roof covered by a fixed roof. Emissions from these tanks are often captured rather than released into the atmosphere, but if they are modeled they can be modeled as fixed roof tanks.
Modeling Tanks
For both tank types, building downwash may be a concern. For this reason, it is necessary to create a circular building to represent the tank structure and a point source or point sources to represent the release of emissions. BPIP, the AERMOD model’s building downwash processor, only calculates building downwash for point sources, making other source types ineffective in this scenario.
As the vertical momentum and flow rate of tank emissions are generally small, small values for the exit velocity and stack diameter should be chosen. An ambient release temperature should also be specified.
The placement of the point sources is dependent on the tank type, as is illustrated in the diagram below:
Exit Velocity |

EPA Sets First National Limits to Reduce Mercury and Other Toxic Emissions from Cement Plants
WASHINGTON (August 9, 2010) - The U.S. Environmental Protection Agency (EPA) is issuing final rules that will protect Americans’ health by cutting emissions of mercury, particle pollution and other harmful pollutants from Portland cement manufacturing, the third-largest source of mercury air emissions in the United States. The rules are expected to yield $7 to $19 in public health benefits for every dollar in costs. Mercury can damage children’s developing brains, and particle pollution is linked to a wide variety of serious health effects, including aggravated asthma, irregular heartbeat, heart attacks, and premature death in people with heart and lung disease.
Program Lightens Greenhouse Gas Emissions
ALBERTA (August 9, 2010) - A new commercial lighting incentive program will give business owners some bright ideas to boost energy efficiency. Under a $4 million pilot program, Albertans who operate restaurants, offices, warehouses and other businesses are eligible for a provincial rebate of between $37,500 and $375,000, depending on the building type, when energy-efficient lighting is installed in their businesses.
The initiative takes effect immediately and will provide a range of rebates, depending on the type of retrofits. All participants must undertake a pre-retrofit assessment and demonstrate the potential for energy savings to be eligible for rebates.
Third Round of Climate Talks Begin in Bonn
(August 4, 2010) - The third round of UN climate change negotiations this year kicked off on Monday with representatives from 178 governments meeting in Bonn, Germany. The Bonn UN Climate Change Conference (2 to 6 August) is designed to prepare the outcomes of the UN Climate Change Conference in Cancún in November and December.
"Governments have a responsibility this year to take the next essential step in the battle against climate change," said UNFCCC Executive Secretary Christiana Figueres. "How governments achieve the next essential step is up to them. But it’s politically possible. In Cancún, the job of governments is to turn the politically possible into the politically irreversible," she said.
Stricter Rules on Industrial Emissions
(July 7, 2010) - Clearer rules and cleaner air are among the aims of the Industrial Emissions Directive approved by the European Parliament on Wednesday. Stricter limits will apply for air pollution for example, although Member States will have some flexibility to extend deadlines for power plants or waive the rules for other installations in special cases.
The Industrial Emissions Directive aims to improve health and environment protection, while making the rules clearer and easier to implement. It updates and merges seven pieces of existing legislation, including directives on large combustion plants and Integrated Pollution Prevention and Control (IPPC), the latter covering around 52,000 industrial and agricultural installations with a high pollution potential, from refineries to pig farms.
