Gaoqiao has two coking units this was the larger / newer (2004 – 2 drum) unit that had the fire. Gaoqiao was one famous worldscale China refineries that first made switch from domestic sweet crude to sour imported crude (and anode to fuel coke – although some is still used as higher sulfur calcinable blend coke). Gaoqiao also had tank fire near two coking units back in May 9, 2010.
