Method of removing iron contaminants from liquid streams during the manufacture and/or purification of aromatic acids |
| abstract |
The present invention relates to the control or removal of the amount of dissolved iron that may or may be present in the liquid process stream in the production of aromatic carboxylic acids. The invention also relates to the control or removal of dissolved iron contaminants present in the liquid stream during the preparation of the crude aromatic acid. The present invention relates to the control or removal of dissolved iron contaminants present in the liquid stream during the purification of crude aromatic acids. The invention also relates to reducing the formation of iron oxides on the equipment surface used during the preparation of crude aromatic acids and / or during the purification of crude aromatic acids. |
