Questor is an international environmental oilfield services provider founded in late 1994 and headquartered in Calgary, Alberta, Canada with a field office located in Grande Prairie, Alberta. The Company is focused on clean air technologies with activities in Canada, the United States, Europe and Asia. Questor designs and manufactures high combustion efficiency waste gas incinerators for sale or for use on a rental basis and also provides combustion-related oilfield services. The Company`s proprietary incinerator technology destroys noxious or toxic hydrocarbon gases which enables regulatory compliance, environmental protection, public confidence and reduced operating costs for customers. Questor is recognized for its particular expertise in the combustion of sour gas (H2S). The technology creates an opportunity to utilize the heat generated from efficient combustion which can be been used for water vapourization, process heat and power generation, through ClearPower Solutions (a subsidiary of Questor). While Questor`s current customer base operates primarily in the crude oil and natural gas industry, the Company`s combustion technology is applicable to other industries such as landfills, water and sewage treatment, tire recycling and agriculture.
