The existing system was unable to meet design requirements, potentially due to solids deposition not considered in the initial design.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Analysis<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Papagari approached this problem with Datacor Fathom\u2019s Settling Slurry (SSL) add-on module to consider the additional hydraulic effects of slurry flow, including identifying if any areas had deposition concerns.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A model was built and validated against plant data by adjusting pipe resistances. Non-standard frictional losses, such as those through heat exchangers, were modeled using resistance curves from Pressure Loss vs. Flowrate information. The model also accommodated temperature-dependent fluid properties as the fluid was heated and cooled through heat exchangers (Figure 1).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Solution<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The model identified several slurry deposition areas (Figure 2) which were later confirmed by observation during a system turnaround. This deposition caused higher system losses which reduced the slurry recirculation rate and caused reliability issues.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Papagari suggested replacing a problematic 8-inch pipe with a reducer tee to maintain high fluid velocity. Along with this, other modifications on pump suction and discharge piping were suggested to reduce friction and increase circulation through pump.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These changes increased reliability by avoiding deposition and simultaneously increased recirculation rate by 15%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The piping changes were so effective that an up-sized replacement pump to further drive flow was canceled, a capital cost savings of $435K. The improved reliability and reduced shutdowns further added approximately $247K in savings per year.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/flumen.clients.cake.fm\/wp-content\/uploads\/2026\/07\/CS_Fathom_LyondellBasell_26_01.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Read the article<\/a><\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"LyondellBasell engineer, Rajitha Papagari, performed a reduced downtime and maintenance costs reliability study on a polymer slurry cooling system used to maintain a stable temperature in a reactor, critical to maintaining product quality.
