UDL Uniform Density Loading

When loading cracking furnaces, it is crucial that every tube is loaded with exactly the same amount at the same speed and that a virtually consistent density is achieved.

If the reactor is loaded using the conventional sock-loading method, hot spots will develop in certain circumstances due to an unequal gas flow rate, following which tears in the tubes may occur due to overheating. The degree of efficiency is also not optimum due to the widely differing density of the individual pipes. In the case of sock loading, the loss of pressure is approx. +/- ≤ 10%. Furthermore, prior to the works, the exact measured amount of catalyst must be prepared which means loading the catalyst into socks so that each tube can be identically loaded.

Our UDL uniform density loading technology - which we use in either its manual or automatic version - is easier, faster and better. The reactor loading carried out by using UDL manual loading guarantees a consistent and good loading result.

For the even more efficient and consistent automatic loading of all tubes, we recommend using UDL automatic. You save up to 20% more time and the loss of pressure is just +/- ≤ 3%.
