The process of ammonia evaporation from latex tailings using a bubble column fitted with a mixing agitator.

Abstract

OCR 09WP 18 / 11 / 2567 This process involves evaporating ammonia or ammonium laurate from the latex residue. The process of placing latex wastewater containing ammonia or ammonium laurate into a bubble column equipped with an agitator. Air is then fed into the bottom of the bubble column, causing small air bubbles to rise to the top. In a bubble column, as air bubbles float within it, ammonia or ammonium laurate evaporates. It enters the air bubbles and floats out of the bubble column, reducing the amount of ammonia in the latex. Then, the process is repeated. Add formic acid or sulfuric acid to reduce the amount of latex foam at the top of the bubble column.

Claims

OCR 09WP 18 / 11 / 2567 1. The ammonia evaporation process in latex tailings using a bubble column fitted with a mixing agitator consists of: The steps are as follows: A. Load the latex containing ammonia or ammonium laurate into the installed bubble column. Diffusers and agitators, where the agitator speed creates flow in the bubble column within a certain range. Laminar flow: In this step, the latex tailings are packed into a bubble column with an agitator for mixing. Spinning B. Air is fed into the latex wastewater contained in the bubble column, where a rotating agitator is used to mix it. Small air bubbles, the size of which depends on the diameter of the diffuser hole. The air bubbles have a diameter between 0.01 millimeters and 5 millimeters. In this step, air bubbles will float in a bubble column containing the latex sludge, with a rotating mixing blade. C. Add formic acid or sulfuric acid when latex foam accumulates on the top of the bubble column. This step yields latex without latex foam, packed in a bubble column with a rotating mixing impeller. live 2. Ammonia evaporation process in latex tailings using a bubble column fitted with a mixing agitator, as per claim 1. Where the impeller can be selected from paddle type, turbine type, and other types of impellers. Propeller, anchor-type agitator, or helical ribbon agitator.
