Plume-RT is an on-line user interface developed by RWDI AIR Inc. that uses accepted regulatory dispersion models to predict current and future Sulphur dioxide (SO₂) concentrations associated with sour gas release events. Modelling uses current meteorological conditions and regional weather forecasts to predict ground-level SO₂ concentrations for the current hour and provides 24-hour forecasts over the modelling domain.

By using local meteorology, Plume-RT provides a realistic representation of the severity and distribution of the ground-level SO₂ touchdowns. Plume-RT is an effective tool for managing ground-level SO₂ touchdowns which vary in space, time and are not persistent.

These predictions aid decision-makers, field operators, and regulators to manage and mitigate risks associated with planned and accidental release events at well sites, gas plants and air sheds. Chemical releases may occur due to well test flaring, incineration, drilling, servicing, completion operations and workovers. Integration with a continuous emission management system enables Plume-RT to be utilized in a permanent facility for stack top temperature reduction applications, while ensuring that ambient air quality objectives are met.

Modelling results are available as a series of reports, graphs and animations that can be accessed quickly and remotely by a secure web site or by automatic email.

The Plume-RT solution provides the Oil & Gas Industry with a full life-cycle tool that can be used from drilling to well abandonment to assist with the air quality issues resulting from ignited sour gas.
