Product quality correction for ethoxylation unit
Thread Content
I need help from experts: 1. How can one determine the amount of ethylene oxide that needs to be added to adjust non-ionic surfactants based on their cloud point? 2. How to determine the amount of acetic acid required for neutralization based on the pH value? For example, if the total volume of the reactor is 28 tons and the amount of potassium hydroxide catalyst used is 57.14 kg, with a desired pH of 7.1 (the target range being 5–6), how much acetic acid with a concentration of 99.9% should be added?
The cloud point is related to the properties of the raw materials and the number of ethylene oxide additions, and can be determined through empirical experience. The pH value is related to acid-base neutralization, and it can be calculated using knowledge from junior high school chemistry.
Are there any experts available to answer questions? More specifics are needed
