How to safely discharge ammonia-containing methanol?
Thread Content
As the title suggests, the cumulative ammonia level in the system has been high recently, and we have been compensating for this by reducing the cooling capacity of the acidic gas cryocooler in order to raise the temperature back up. The temperature cannot be too high; once it is, the nitrogen oxide levels measured by the system’s on-line sulfur recovery monitoring device will exceed the allowed limits. Ammonia-containing methanol is recovered through sulfur release combustion, which results in significant waste. How can ammonia-containing methanol be safely discharged from the return tank at the top of the thermal regeneration tower, so that it can be replaced with fresh methanol? Please share any good ideas you have.
It is discharged from the bottoms of V05 and V06 at the top of the thermal regeneration tower; in particular, the bottom of V05 is where the most ammonia accumulates. After being discharged into underground tanks, it is sent to a company to be taken in, and the waste alcohol is sold
I mean, how to install it safely? The rubber hoses need to be connected and led inside the vehicle. Sulfur is quite heavy; isn’t that dangerous?
We all use underground trough pumps to directly pump it into the methanol tankers. Before starting the pump, secure the outlet hose inside the tank truck, close the lid of the tank truck used to store methanol, set up warning barriers around the tank truck, and then start the pump.
Thank you. Then do you test for ammonia in methanol? To what extent should it be ranked? How often is it scheduled, and what is the volume of low-iodine wash gas?
We discharge it into the fusel oil tank, pump it out with a fusel oil pump, and load it onto the vehicle using a flexible hose. The flavor must be strong; it’s necessary to get in touch with the buyer
The excess can be drained to an underground tank through the return pump’s drain line, and fresh methanol can then be added to the system. The outlet temperature in the conversion system can be reduced, and the amount of ammonia wash water used can be increased in order to lower the ammonia content inside the low-methanol section. A high ammonia content there can cause various problems over time; it can easily lead to blockages in the concentration line as well as accelerated equipment corrosion
