Project Background
Tesoro Refining and Marketing Company (Tesoro) has implemented major modifications to their coking facility at the Golden Eagle Refinery located at Martinez, California, an essential part of which is the coke handling system for loading coke product into trucks for transport to market.
Roberts & Schaefer Company provided engineering and procurement services for the coke handling system. The system incorporates two switchback conveyors, with a transfer station at the switchback. The conveyors receive coke from a feeder/breaker and deliver the product to either of two twin bolted steel loadout silos situated above dual drive-through loading lanes.
The entire facility is enclosed for dust control. In order to circumvent the ventilation problems associated with steam, dust and visibility inside a conventional enclosed conveyor gallery, the conveyors are enclosed locally with light gauge material around the carry and return belts leaving the walkways open for maintenance and ventilation. An automated wash-down system enables cleaning of the enclosed conveyors with spray nozzles located inside the enclosure and pipe drainage to sump pumps.
The two loadout lanes (one below each silo) are fully automated. RF readers and weigh scales communicate with a PLC to control the silo discharge slide gates for loading trucks within plus/minus 200 lbs. The trucks exit the enclosed loading lanes through an automatic wash station to remove latent dust prior to entering the State road system.
