Problems with atmospheric and vacuum distillation
Thread Content
What is the difference between reduced vacuum pressure and negative pressure in a heating furnace? What are the specific differences?
What difference are you referring to? The negative pressure in a heating furnace is created by the furnace’s natural suction force; it is a naturally occurring phenomenon. On the other hand, the vacuum level in a vacuum tower is achieved through the use of vacuum pumps or steam ejectors to create negative pressure, which is a forcefully induced condition! Atmospheric pressure minus absolute pressure equals vacuum level, while absolute pressure minus atmospheric pressure equals gauge pressure!
