Petcoke is the coke that, in particular, derives from a final crackingprocess\u2014a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains\u2014that takes place in units termed coker units. (Other types of coke are derived from coal.) Stated succinctly, coke is the \u201ccarbonization product of high-boiling hydrocarbon fractions obtained in petroleum processing (heavy residues).\u201d Petcoke is also produced in the production of synthetic crude oil (syncrude) from bitumen extracted from Canada\u2019s oil sands and from Venezuela\u2019s Orinoco oil sands.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5cfa316 elementor-widget elementor-widget-button\" data-id=\"5cfa316\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"#\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-text\">Request A Quote<\/span>\n\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-69744ad7 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"69744ad7\" data-element_type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-210ac271\" data-id=\"210ac271\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-3234d1c3 elementor-widget elementor-widget-text-editor\" data-id=\"3234d1c3\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span class=\"x-el x-el-span c1-86 c1-87 c1-b c1-c c1-d c1-e c1-f c1-g\">In petroleum coker units, residual oils from other distillation processes used in petroleum refining are treated at a high temperature and pressure leaving the petcoke after driving off gases and volatiles, and separating off remaining light and heavy oils. These processes are termed \u201ccoking processes\u201d, and most typically employ chemical engineering plant operations for the specific process of delayed coking.<\/span><\/p><p><span class=\"x-el x-el-span c1-86 c1-87 c1-b c1-c c1-d c1-e c1-f c1-g\">This coke can either be fuel grade (high in sulfur and metals) or anode grade (low in sulfur and metals). The raw coke directly out of the coker is often referred to as green coke. In this context, \u201cgreen\u201d means unprocessed. The further processing of green coke by calcining in a rotary kiln removes residual volatile hydrocarbons from the coke. The calcined petroleum coke can be further processed in an anode baking oven to produce anode coke of the desired shape and physical properties. The anodes are mainly used in the aluminium and steel industry.<\/span><\/p><p><span class=\"x-el x-el-span c1-86 c1-87 c1-b c1-c c1-d c1-e c1-f c1-g\">Petcoke is over 90% carbon and emits 5% to 10% more carbon dioxide (CO2) than coal on a per-unit-of-energy basis when it is burned. As petcoke has a higher energy content, petcoke emits between 30 and 80 percent more CO2 than coal per unit of weight. The difference between coal and coke in CO2 production per unit of energy produced depends upon the moisture in the coal, which increases the CO2 per unit of energy \u2013 heat of combustion) and on the volatile hydrocarbons in coal and coke, which decrease the CO2 per unit of energy.\u00a0<\/span><\/p><p><span class=\"x-el x-el-span c1-86 c1-87 c1-b c1-c c1-d c1-e c1-f c1-g\">There are at least four basic types of petroleum coke, namely, needle coke, honeycomb coke, sponge coke and shot coke. Different types of petroleum coke have different microstructures due to differences in operating variables and nature of feedstock. Significant differences are also to be observed in the properties of the different types of coke, particularly ash and volatile matter contents.<\/span><\/p><p><span class=\"x-el x-el-span c1-86 c1-87 c1-b c1-c c1-d c1-e c1-f c1-g\">Needle coke, also called acicular coke, is a highly crystalline petroleum coke used in the production of electrodes for the steel and aluminium industries and is particularly valuable because the electrodes must be replaced regularly. Needle coke is produced exclusively from either FCC decant oil or coal tar pitch.<\/span><\/p><p><span class=\"x-el x-el-span c1-86 c1-87 c1-b c1-c c1-d c1-e c1-f c1-g\">Honeycomb coke is an intermediate coke, with ellipsoidal pores that are uniformly distributed. Compared to needle coke, honeycomb coke has a lower coefficient of thermal expansion and a lower electrical conductivity.\u00a0<\/span><\/p><p><span class=\"x-el x-el-span c1-86 c1-87 c1-b c1-c c1-d c1-e c1-f c1-g\"><strong class=\"x-el x-el-span c1-3a c1-3b c1-b c1-9v c1-1k c1-1e c1-9w\">Fuel-grade coke<\/strong>\u00a0is classified as either sponge coke or shot coke morphology. While oil refiners have been producing coke for over 100 years, the mechanisms that cause sponge coke or shot coke to form are not well understood and cannot be accurately predicted. In general, lower temperatures and higher pressures promote sponge coke formation. Additionally, the amount of heptane insolubles present and the fraction of light components in the coker feed contribute.<\/span><\/p><p><span class=\"x-el x-el-span c1-86 c1-87 c1-b c1-c c1-d c1-e c1-f c1-g\">While its high heat and low ash content make it a decent fuel for power generation in coal-fired boilers, petroleum coke is high in sulfur and low in volatile content, and this poses environmental (and technical) problems with its combustion. Its gross calorific value (HHV) is nearly 8000 Kcal\/kg which is twice the value of average coal used in electricity generation. A common choice of sulfur recovering unit for burning petroleum coke is the SNOX Flue gas desulfurisation technology, which is based on the well-known WSA Process. Fluidized bed combustion is commonly used to burn petroleum coke. Gasification is increasingly used with this feedstock (often using gasifiers placed in the refineries themselves).\u00a0<\/span><\/p><p><span class=\"x-el x-el-span c1-86 c1-87 c1-b c1-c c1-d c1-e c1-f c1-g\"><strong class=\"x-el x-el-span c1-3a c1-3b c1-b c1-9v c1-1k c1-1e c1-9w\">Calcined petroleum coke<\/strong>\u00a0(CPC) is the product from calcining petroleum coke. This coke is the product of the coker unit in a crude oil refinery. The calcined petroleum coke is used to make anodes for the aluminium, steel and titanium smelting industry. The green coke must have sufficiently low metal content to be used as anode material. Green coke with this low metal content is called anode-grade coke. When green coke has excessive metal content, it is not calcined and is used as fuel-grade coke in furnaces.\u00a0<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Petroleum Coke Petroleum coke, abbreviated\u00a0coke\u00a0or\u00a0petc &hellip;<\/p>\n<p class=\"read-more\"> <a class=\"\" href=\"https:\/\/hkg-petroleum.com\/index.php\/products\/petroleum-coke\/\"> <span class=\"screen-reader-text\">Petroleum Coke<\/span> \u67e5\u770b\u5168\u6587 &raquo;<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":778,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"no-sidebar","site-content-layout":"page-builder","ast-global-header-display":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"disabled","ast-breadcrumbs-content":"","ast-featured-img":"disabled","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","footnotes":""},"class_list":["post-798","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/hkg-petroleum.com\/index.php\/wp-json\/wp\/v2\/pages\/798","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hkg-petroleum.com\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/hkg-petroleum.com\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/hkg-petroleum.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/hkg-petroleum.com\/index.php\/wp-json\/wp\/v2\/comments?post=798"}],"version-history":[{"count":4,"href":"https:\/\/hkg-petroleum.com\/index.php\/wp-json\/wp\/v2\/pages\/798\/revisions"}],"predecessor-version":[{"id":1000,"href":"https:\/\/hkg-petroleum.com\/index.php\/wp-json\/wp\/v2\/pages\/798\/revisions\/1000"}],"up":[{"embeddable":true,"href":"https:\/\/hkg-petroleum.com\/index.php\/wp-json\/wp\/v2\/pages\/778"}],"wp:attachment":[{"href":"https:\/\/hkg-petroleum.com\/index.php\/wp-json\/wp\/v2\/media?parent=798"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
