Processes for recovering a purified aromatic carboxylic acid include contacting a crude aromatic carboxylic acid with hydrogen 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 apparatus to remove a liquid filtrate, washing the solid/liquid mixture in the rotary pressure apparatus with a wash fluid to form a washed solid/liquid mixture, and drying the washed solid/liquid mixture in the rotary pressure apparatus with an inert gas to form a filter cake comprising purified aromatic carboxylic acid solids and a wet gas stream; withdrawing the wet gas stream from the rotary pressure filter apparatus while maintaining the wet gas stream at a pressure above ambient; and recovering the purified aromatic carboxylic acid solids from the filter cake.

A filtration device has a primary conveyer tank which is equipped with a first conveyer, a primary drum filter which rotates inside the primary conveyer tank, a secondary conveyer tank which is equipped with a second conveyer and a secondary drum filter which rotates inside the secondary conveyer tank. Liquid in the primary conveyer tank passes through a first opening to flow into the secondary conveyer tank. Clean liquid flowing into a first clean tank is supplied to a low-pressure-side supply system by a first pump. Super-clean liquid having been filtered by the secondary drum filter passes through a second opening to flow into a second clean tank, and then is supplied to a high-pressure-side supply system by a second pump.

A filtration device efficiently sizes removal of unnecessary substances adhering to and deposited on a filter medium of a filter element during filtration and backwashing (cleaning) from target (non-filtered) substances. The filter element captures substances in a fluid on one surface of a filter medium. The captured substances are separated from the filter medium during backwashing. A brush moves relative to the one surface of the filter medium and assists in separating the captured substances and sifting during the relative movement. The backwashing starts when a differential pressure between both surfaces of the filter medium exceeds a predetermined value, or the like while performing the filtration, and returns to filtration after the differential pressure is eliminated or after a predetermined time elapses. The brush sifts the unnecessary substances from the captured substances and passes the removal to the other surface side during the filtration.
