What is Medusa Diamond and fast crash Syndrome and what is being done about it?
Medusa Diamond syndrome is when gorgeous perfectly formed crystals turn to chalk over night or the "sauce" fast crashes into gravel while trying to initially precipitate out and grow the crystal. Techniques that formerly worked perfectly, no longer work.
Lots of effort trying to discover what was happening, as well as finger pointing, but it was narrowed down to something in the LPG, either present in virgin product, or a buildup of mono and sesquiterpenes from recycle.
Analysis of a chromatography column used to clean up the LPG revealed that the oxgenate and nitrogen layers in the column were enriched, and an analysis of the media suggested that the culprits were the Methanol and Diethanolamine used to remove CO2 and sulfur compounds from the sour crude now being released from national reserves.
Two methods have been investigated to remediate the problem, the first column chromatography and the second Liquid Liquid Extraction (LLE). While the debate as to exact cause remains active, both methods take out whatever it is creating the problem.
The following link outlines those systems and our current remediation status:
