Tuesday, October 2 7:30 - 9:00 PMDilbit. Crude. Refined.
Pipelines are very much in the news and the word “dilbit” is brought up as a special concern. Is this true? What is dilbit? We have been given many descriptions of this material and warned of its deleterious effect on our infrastructure and our planet. The talk will explain what dilbit is and how it resembles and differs from crude oil. Why is dilbit important enough to build expensive pipelines and set off vicious political battles?
Speaker: Joe Boivin
Joe Boivin is retired from the oil industry after 45 years of work in the chemical and corrosion aspects of oil and gas production and transmission. He has previously presented a talk to CALL on pipelines. He is the co-cordinator of the Science and Environment lecture series.

Active cloud seeding is being carried out on a routine basis to minimize this threat. This talk will give an overview of the history of hail suppression, describe current activities and assess the impact of the current program using Alberta case studies. Anyone who owns a vehicle, boat, house, business establishment or any other form of physical property in this part of Alberta will find this presentation interesting.

He received graduate degrees at the University of Alberta and the University of Wyoming based on hail storm research, radar analysis of hail storms and controlled cloud seeding experiments. He has worked actively in this area for more than 40 years in Canada and abroad and is the author of numerous scientific and technical publications that cover all aspects of hail suppression and precipitation enhancement.
