3. Application: FGD、PTA、 Oil&Gas 、Chemical&Petrochemical 、 Water Treatment
FGD
PTA
In the reaction process of TA section, there is acetic acid corrosion, and many equipment are lined with titanium materials. In PTA section, because catalyst palladium and products are sensitive to metal ions such as Cu²﹢、Cr²﹢、N﹢、Fe³﹢, these metal ions have toxic effects on palladium and reduce product quality. Therefore, titanium is also selected as the material. Titanium clad steel plate, titanium clad stainless steel plate are selected according to the requirements of process and cost Manufacture of PA-PTA equipment with titanium clad stainless steel clad steel three-layer clad plate.
The selection of composite plates for PA-PTA equipment is as follows:
