Vent Stacks are used to discharge gasses to the atmosphere at a safe and environmentally friendly elevation.
The required elevation and discharge velocity is dictated by a variety of design parameters.
These include the vent stack’s location and surrounding structures as well as the vent gas temperature,
constituents, allowable ground level concentrations, odor threshold, corrosion requirements and structural integrity.
Structural integrity should consider all possible live loads, earthquake and wind conditions.
