Use of pressurized wet gas lines to prevent fouling in purified terephthalic acid (PTA) filters and lines |
| abstract |
A process for recovering purified aromatic carboxylic acid, comprising: contacting hydrogen and raw aromatic carboxylic acid in the presence of a catalyst in a hydrogenation reactor to form a purified aromatic carboxylic acid; Crystallizing the purified aromatic carboxylic acid to form a solid / liquid mixture comprising purified aromatic carboxylic acid solids; Filtering the solid / liquid mixture in a rotary pressure filter device to remove liquid filtrate; Cleaning the solid / liquid mixture in the rotary pressure filter device with a cleaning fluid to form a cleaned solid / liquid mixture; And drying the washed solid / liquid mixture in the rotary pressure filter device with an inert gas to form a filter cake and a wet gas stream comprising purified aromatic carboxylic acid solids; Withdrawing the wet gas stream from the rotary pressure filter device while maintaining the wet gas stream at a pressure above ambient; And recovering the purified aromatic carboxylic acid solids from the filter cake. |
