The Revamp consisted of a grass roots 30 MBPD Vacuum Distillation Unit (VDU).\u00a0 This unit received gas oil feed from two existing Crude Distillation Units (CDU). An important feature of this revamp was the recovery of heat from the VDU products into the CDU feed.\u00a0 Crossing battery limits for heat integration is an uncommon innovation but resulted in additional lift for the upstream Crude Units which had been previously constrained.<\/p>\n<p><strong>New Low Sulfur Vacuum Gas Oil (LSVGO) Product<\/strong><\/p>\n<p>As a result of the new heat integration, additional lift was available in the CDUs enabling the units to improve the diesel recovery from gas oil directly in the CDUs.\u00a0 The CDU gas oil was then processed further in the downstream VDU to recover all the remaining diesel from gas oil and produce a new, Low Sulfur Vacuum Gas Oil (LSVGO) product, further increasing the profitability of the refinery.[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/4&#8243;][vc_column_text]<i class=\"fa fa-clipboard\" aria-hidden=\"true\"><\/i> <strong>Scope of Work<\/strong><\/p>\n<p>Process \/ Chemical<\/p>\n<p><i class=\"fa fa-calendar\" aria-hidden=\"true\"><\/i> <strong>Schedule<\/strong><\/p>\n<p>2006-2007<\/p>\n<p><i class=\"fa fa-industry\" aria-hidden=\"true\"><\/i> <strong>Market<\/strong><\/p>\n<p>Refining, Oil &amp; Gas<\/p>\n<p><i class=\"fa fa-map-marker\"><\/i> <strong>Location<\/strong><\/p>\n<p>Louisiana[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_section][vc_row][vc_column width=&#8221;3\/4&#8243;][vc_single_image source=&#8221;featured_image&#8221; img_size=&#8221;large&#8221;][vc_column_text]Declining Diesel Recovery As a result of increased bottoms yield in their supply of crude (purchased crude becoming progressively heavier), the client\u2019s diesel recovery from gas oil progressively declined, resulting in incremental diesel being downgraded to 6 Oil. \u00a0Heat Recovery Feature Polaris provided a Revamp that allowed the refinery to efficiently recover [&hellip;]<\/p>\n","protected":false},"featured_media":0,"menu_order":2,"template":"","class_list":["post-1064","project","type-project","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/polarisepc.com\/index.php\/wp-json\/wp\/v2\/project\/1064","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/polarisepc.com\/index.php\/wp-json\/wp\/v2\/project"}],"about":[{"href":"https:\/\/polarisepc.com\/index.php\/wp-json\/wp\/v2\/types\/project"}],"wp:attachment":[{"href":"https:\/\/polarisepc.com\/index.php\/wp-json\/wp\/v2\/media?parent=1064"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
