Does anyone know what equipment is used to dehydrate petroleum asphalt? ? ?

1. High-efficiency centrifuge 2. Oven, or muffle furnace. I guessed it. Hehe, would you like to see other people’s correct answers?

It can be equipped with a small thermal oil heating system. Many asphalt dehydrations use this system, which is very practical.

If you want to dehydrate asphalt in the laboratory, you can only slowly heat and stir. The only way is not to cause asphalt to overflow until all the foam is gone.

Under normal circumstances, it is normal for petroleum asphalt to contain a small amount of water. When doing experiments, by stirring while heating, the foam can be eliminated before making samples. If there is a lot of water, it is a problem with the upstream device. It may be that the heat exchanger of the device is leaking, or for other reasons, water has leaked into the asphalt. At this time, it is necessary to contact the upstream device to find out the cause.

There is water in asphalt. As a person who has been producing asphalt in a refining and chemical company for almost 20 years, I have rarely heard of it. . . It may also be caused by the leakage of the water cooler behind the heat exchanger (but the temperature is also above 150 degrees, and even in large tanks it is above 130 degrees. . . ) (There is another reason. It is probably due to the management of the large tank, and the coil leaked in. . . ) Bitumen is generally the bottom oil remaining in the vacuum tower at the suitable extraction temperature of naphthenic crude oil. . . At a temperature of 360-390, the moisture is generally gone, right? However, there is a product called water-emulsified asphalt in road asphalt. . . That is artificially using asphalt to tell the emulsifier to add emulsifiers and stabilizers to form a mixture in a liquid-liquid or liquid-solid state that can be stored for a period of time. . . If the asphalt contains water for whatever reason, you can use vacuum distillation to steam out the water. . . For other methods, I think heating it directly to about 230 degrees under normal pressure can evaporate a small amount of water. . . :lol This post was last edited by wangsc on 2009-2-26 14:41 ]

Can you tell me where I can buy this equipment? ? ? Thanks

I agree with the 5th floor, asphalt is delivered to over 160 degrees here! ! How could there be water! ! :handshake

The possibility of installing asphalt with water should be very small. The pressure of asphalt in the heat exchanger is higher than that of deoxygenated water. Even if the heat exchanger of the installation leaks, the asphalt will leak into the water and the water will not leak out.； The possibility of coil leakage in the tank farm is relatively high.
