How to control parameters for producing asphalt through atmospheric and vacuum distillation?

The parameter control for producing asphalt relies mainly on the negative pressure difference between the vaporization sections at the top and bottom of the tower; the smaller this difference, the better. It is also desirable for there to be a larger difference between the feed temperature and the temperature at the bottom of the tower. If the steam flow used for venting at the bottom of the tower is too low, the light components cannot rise to the upper levels, while if the flow is too high, it affects the vacuum level in the vaporization sections. Operators who are able to adjust the parameters for asphalt production must have sufficient experience, and this is also one of the criteria used to assess the skill level of such operators. Due to differences in the processing capacity of the plants and the properties of the crude oil, it is not possible to provide exact figures. To obtain qualified products, it is necessary to rely on trial and error during production. I have a set of guidelines that can help with this process; if you need them, please send an email to mpcchuanp@163.com so that I can respond to you

Which parameters weren’t clarified? Our factory specializes in producing asphalt – does it refer to the manufacturing process?
