Description

Analysis for continuous hydrocarbon monitoring and meteorological data at the two stations in the Three Creeks area showed that elevated hydrocarbon concentrations were associated with low wind speed, likely promoted by nocturnal gravitational drainage flow. In addition with higher concentrations of THC may be promoted by lower mixing height, elevated NMHC concentrations were more likely to be measured during the warmer months, when evaporation losses are more likely.

Description

Alberta Environment conducted two air sampling surveys in the vicinity of heavy oil cold flow tanks near Bonnyville, Alberta. The surveys were initiated by public concern with odours and potential health effects. Heavy oil extracted using the cold-flow technique is heated in onsite storage tanks to reduce viscosity. Lowering the viscosity of the oil allows the product to be pumped from the onsite storage to tank trucks for treating and upgrading. The onsite storage tanks may not have vapour recovery systems installed and water vapour and volatalized hydrocarbons can be released from the theif hatch at the top of the tank. These tanks are 7-10 meters in height.
