Gasification slag rheology in titanium-rich, iron and calcium-aluminosilicate glasses

The Texaco Gasification Process (TGP) employs a high temperature, high pressure stagging gasifier to produce synthesis gas for power, hydrogen, and chemicals. During gasification most of the ash collects on the refractory wall to form a molten glass or slag. The viscosity of the slag plays a key role in determining operating conditions. Insufficient operating temperatures can cause erratic slag flow from the unit, while excessive operating temperatures can result in rapid refractory wear. Waste streams that are high in titanium (e.g. plastics and tires where TiO{sub 2} is used as a pigment) are being tested for gasification by Texaco. Texaco has developed a process to liquify both used plastics and tires with heated oil to produce a pumpable feed referred to as plastic-oil or tire-oil. Other major elements found with the titanium in these feeds include calcium, aluminum, iron, silicon, and zinc. The zinc sublimes during gasification, leaving behind a titanium-rich calcium-aluminosilicate glass with various amounts of iron.
