Overcoming difficulties with caviar formation, desanding of converter I, Leuna, 1941
The life of a coal stall was in most cases limited by the grinding action of the solid components of the coal. The so-called caviar produced the greatest amount of difficulties. Its elimination was accomplished by the removal of the coarsest particle from the first converter, the converter 1 desanding. Before desanding was introduced, perforated thermocouple-protecting tubes and catalyst tubes almost ground through were found in almost every dismantling of the stalls. Small-scale and large-scale solutions to this problem were discussed. A sketch of desanding in converter I was given. Another sketch showed the pipe line of the HOLD from the converter to the pressure relief. A screen analysis of the converter I desanding and of the normal HOLD were made to determine the proportion of coarse and fine sludge. Curve A and curve B given on two graphs showed the percent distribution and the actual amount involved. Sheet 1 gave diagrams of the residue and damage by wear in converters 1 and 2 of stall 8. Sheet 4 showed a diagram of converter 1 with an inclined plane for desanding and sheet 8 gave the desanding results from a test on converter 1. The final conclusion drawn was that desanding of converter 1 completely eliminated the formation and settling of caviar in the coal stall converters. The desanding process was one in which about 10% of the sludge in the first converter was periodically withdrawn from the bottom of converter, often to be sent on to be combined with hot oil letdown for further processing. The desanding residue could be readily carbonized because the proportion of asphalt to solids was very good. 8 diagrams
