REFINERY
The refining process, which seeks to extract maximum value from the resources within the system, is designed to minimize the potential for waste due to spills. Extensive drainage and water treatment systems are integral to both environmental protection and the efficient use of petroleum resources. Most refineries also have associated marine terminals, transfer stations and storage facilities equipped with a range of spill-prevention technologies.
Gravity Oil/Water Separators
are the primary means of recovering any oil spilled within the refinery system. These simple but highly effective devices collect wastewater in a tank that allows any oil, which is generally lighter than water, to float the surface. A baffle directs the oily top layer out of the tank toward one outflow pipe while a weir constructed behind the baffle collects the clean water for removal by another.
Overfill Sensors
attached inside the roof of a storage or transfer tank identify when the desired level of product has been achieved within the tank, triggering an automatic shut-off valve to prevent overfilling.
Self-adjusting Cargo Connections
at marine terminals prevent spills by compensating for the movement of the ship on the water. The connector arms can swing both vertically and horizontally, eliminating potential stress on the connection point.
