What is the most appropriate value for reducing the top ph control?
Thread Content
Recent observations have shown that when the pH value during degumming is below 6.5, the degummed liquid becomes significantly turbid and shows strong emulsification; the situation improves markedly when the pH is between 7 and 8, while the degumming effect is even better when the pH is between 8 and 9. So, what is the optimal pH value to maintain? The anti-corrosion guidelines specify that the pH value of organic ammonia neutralizers should be between 6 and 8; the company is quite rigid in its approach, considering any value above 8 to indicate a deviation from the standard.
The setting of these parameters is generally a matter of trade-offs. As you mentioned, a dehydration level of 7-8 yields good results; but although the performance improves at higher levels, does it increase the corrosion on the equipment itself?
For this topic, I’ll help you with oil pretreatment instead; it’s closer to the process you described in your problem.
Control according to the company’s specified indicators upon launch, and accordingly reduce the amount of additives used.
