Abstract
An on-line control and reaction process for pH adjustment and a control device for automatically adjusting pH value are provided. The process includes mixing a first enhancer and a second enhancer, optionally after diluting the first enhancer and/or the second enhancer with water, to form a mixture, setting a base pH value (δ1) and a target pH value (δ2), and adding pH adjuster into the mixture via a pH control unit and mixing to obtain a product with the target pH value. The pH control unit adjusts the adding of the pH adjuster by measuring or inputting certain parameters.
Claims11
An on-line control and reaction process for pH adjustment of a binary enhancer composition comprising a first enhancer and a second enhancer, the process comprising:
- 1) mixing the first enhancer and the second enhancer, optionally after diluting the first enhancer and/or the second enhancer with water, to form a mixture,
- 2) setting a base pH value (δ1) and a target pH value (δ2),
- 3) adding pH adjuster into the mixture via a pH control unit and mixing to obtain a product with the target pH value;
- wherein the pH control unit adjusts the adding of the pH adjuster by measuring or inputting the following parameters:
- a. the solid content ratio of the first enhancer in relation to the mixed product (r), said mixed product comprising the first enhancer and the second enhancer,
- b. the solid content of the first enhancer (α) and the solid content of the second enhancer (β),
- c. the pH value of the first enhancer (a) and the pH value of the second enhancer (b),
- d. the base pH value (δ1) and the target pH value (δ2) as provided in step 2),
- e. the flux of the product.
