pH of the methanol washing system
Thread Content
What is an appropriate pH value for controlling the methanol washing system? How to control and adjust?
It’s better to have a slightly alkaline environment; specifically, caustic soda should be added to the methanol-water separation tower
Some say to use the ammonia content in the system to control the pH value. How is this method monitored?
How are the indicators for controlling the amount of caustic soda added controlled? Thank you!
It is controlled by the pH of the wastewater, usually between 8 and 10
Some marine enthusiasts say that the pH value can be controlled using the system’s ammonia level – is that true?
