The actual production range for the softening point of asphalt products is specified by our factory as 88–92°C.

Our factory produces **10,000 tons of tar annually, using a continuous distillation process with a atmospheric-pressure, single-tower tubular furnace. Recent customer requirements call for the softening point of the asphalt to be maintained between 88–92°C, but it is difficult to achieve such a precise range in actual production. Actually, the softening point of asphalt is kept within a certain range.
The key is to consider the customer’s requirements; any softening point will do
Quality depends on human adjustment; adjusting the softening point is relatively simple
It depends on what type of asphalt your factory plans to produce. Asphalt is classified into low-temperature asphalt, medium-temperature asphalt, and high-temperature asphalt; low-temperature and medium-temperature asphalt are further divided into Type 1 and Type 2. The soft asphalt produced here belongs to the medium-temperature category; there is also high-temperature asphalt, which is also known as modified asphalt. Based on the softening point range you mentioned, it should belong to Type 2 medium-temperature asphalt. Low-temperature asphalt is 35-75. Medium-temperature asphalt is 75-95. High-temperature asphalt stone 95-120. In actual production, the softening point must be controlled according to the customer’s requirements. As for the temperature range you mentioned, it’s not impossible to achieve. It can be achieved as long as the production process and the temperature of the distillation tower are under control. Always remember that the softening point is related to the components in asphalt. As long as the amount of light components decreases, the softening point will naturally increase.
3# qingsheng raw materials, superheated steam, the oil temperature in the second stage, and the processing volume all affect the softening point of asphalt; the key issue is the lag in the analysis results, so making adjustments is not simple
It’s actually not that difficult either; the more stable the production, the better the quality can be guaranteed.
The medium-temperature asphalt produced by our factory has a softening point controlled at 90–92 degrees according to customer requirements, and this is fairly easy to achieve: it is simple to accomplish as long as the feed rate remains stable, the pressures at the top and bottom of the tower are stable, and the oil temperature at the outlet of the tubular furnace is stable. Give it a try
What everyone mentioned upstairs is an ideal scenario that can be achieved; the original poster just needs to keep these influencing factors under control
It’s not the ideal situation, but rather what happens in practice
As long as the instruments in your factory are accurate, the testing is precise, and the operations are stable, it’s quite easy to control the asphalt softening point.
In practice, things may not turn out that way; if operations were that perfect, then the asphalt’s softening point would also be stable
