Quick Summary

In petroleum refining, "off-sites" are crucial facilities that support the main processing units. These include tankage for storage, flare systems for safety, utilities, and environmental treatment units.12

Utilities are essential and comparable to those needed for a small city. Refineries generate steam for process units, requiring water treatment, boilers, and extensive piping. Many also produce electricity and provide clean air for processes. Significant amounts of cooling water are also necessary for condensing hydrocarbon vapors.2

Environmental treatment is vital for managing water used in operations. This water must be purified of hydrocarbons and chemicals before disposal. Process units that release hydrocarbons, gases, or solids are monitored to meet environmental standards. Proper disposal of spent catalysts is also a key environmental consideration.1
