Sulzer GTC has a series of polyester technologies, which apply in case-specific situations. These all integrate together to improve process efficiency, solve specific problems, or make selective debottlenecks. GTC’s portfolio includes paraxylene and meta-xylene raw materials, DMT and PTA, and continuous melt phase polymerization for PET.
The technology addresses oxidation, distillation, esterification, crystallization, and waste-water treatment resulting in lower energy consumption, increased capacity, and yield improvements.
Our GT-CAR carboxylic acid recovery technology that combines liquid-liquid extraction technology with distillation to recover and concentrate carboxylic acids from wastewater.
Unlike traditional PTA purification methods, Sulzer GTC Technology’s GT-PTA family of processes has incorporated critical changes that place it as the forerunner of the next generation of PTA production.
Toluene methylation is an effective and economical solution to maximize PX yields by adding the methyl group from low-cost methanol to the aromatic ring. GT-TolAlk introduces a new way to derive PX while eliminating benzene production.
