摘要

Sulfate process (SP) is an important and mature method to produce titanium dioxide (TiO_2) pigment. It accounts for most of the TiO_2 pigment production in China especially. However, a large amount of water is consumed and a large quantity of effluent is discharged, which may cause water resource waste and serious environmental pollution. Thus, water minimization has great benefits to environmental and industrial sustainability. Both freshwater consumption and wastewater discharge can be minimized by practicing water system integration. Water pinch analysis and group optimization method are chosen for water minimization under a titanium pigment plant event in China. Five schemes are analyzed and an applicable water reuse network is obtained.
