AIChE Annual Meeting
Friday, November 2, 2018 - 8:25am to 8:50am
We present here outcomes from our ongoing program to help avoid cryogenic solids formation in LNG production. A new software tool called ThermoFAST has been developed and endorsed by GPA Midstream to replace the Kohn-Luks Solids Solubility Program. High-pressure visual cells operating at cryogenic temperatures have been constructed and used to produce new solid-liquid equilibrium data to further validate and extend ThermoFAST. These tools have been used to explore phenomena of retrograde solidification in LNG systems, which may lead to novel methods of mitigating inadvertent solids formation in operating plants. Finally, our efforts to develop a more robust sensor capable of directly assessing heavy hydrocarbon freeze-out risk will be described.
