Sinclair Wyoming Refining Company

The Sinclair Refinery has become the most sophisticated refinery – and one of the largest – in the Rocky Mountain region. With gas oil hydrocracking, gas oil hydrotreating, delayed coking units, and the associated hydrogen generation and sulfur plant capacity, the refinery processes heavy sour crude into high-quality, low-sulfur gasoline and diesel fuels. We serve customers in Colorado, Idaho, Nebraska, Nevada, Oregon, Utah, Washington and Wyoming with a team continuously pursuing excellence in safety, environmental compliance, training and refinery utilization.
