Trade press reports indicate that additional Midwest refiners may undertake coker installation projects in the coming years. Husky's refinery in Lima, Ohio, and NCRA's McPherson, Kansas, facility are said to be considering upgrades that would expand coking capacity, which could lead to further changes in average API gravity and refinery yields in the region.
