After appropriate crushing of the calcined coke using both the jaw crusher and roll crusher the test volume of 100 g is measured after vibration and the bulk density is calculated 5 Significance and Use Vibrated bulk density VBD is an indicator of calcined petroleum coke porosity which affects its suitability for use in
Oxbow Calcining produces calcined petroleum coke CPC which is used to make anodes in aluminum smelters Raw material from petroleum coker units is devolatilized and densified in kilns to meet customer specifications [1] such as sulfur content trace metals air reactivity and density The smelter blends the CPC
Previous Work A literature review of prior studies on the impact of coke parameters on bulk density and the previous work in this project on modifying particle shape and packing of a range of filler materials through different crushing technologies have been summarised in previous papers [1 2 3] Laboratory impact type crushers Plant equivalents
3 1 Introduction Pursuant to section 74 of the Canadian Environmental Protection Act 1999 CEPA Canada 1999 the Minister of the Environment and the Minister of Health have conducted a screening assessment of two substances coke petroleum CAS RN Footnote 2 64741 79 3 and coke petroleum calcined CAS RN 64741 05 1 referred to collectively
s crushing and screening the Calcined Petroleum Coke CPC and / or Electrically Calcined Anthracite ECA to different fractions and milling and storing it separately Following this pre determined quantities of different fractions are weighed and transferred to a Sigma Mixer which is heated to about 1600C by therm c fluid The
The production of calcined petroleum coke involves the following key steps Raw Material Green petroleum coke is the primary raw material used for the production of calcined petroleum coke It is obtained as a byproduct of the oil refining process Drying Green petroleum coke is first dried to remove any moisture content
In addition green coke volatility levels can be qualitatively related to calcined coke quality; that is the lower the green coke volatile level the more anisotropic the coke Typically green premium cokes have volatile levels of less than 5% wgt green regular cokes have volatile levels of 6 8% wgt and green isotropic cokes have
Everything You Always wanted to Know about Petroleum Coke A Handbook Allis Mineral Systems Kennedy Van Saun 1993 Google Scholar Paul J Ellis and Christopher A Paul Tutorial Petroleum Coke Calcining and Uses of Calcined Petroleum Coke Prepared for the AIChE 2000 Spring National Meeting Atlanta GA March 5 9 2000
Petroleum coke PC one form of the category of fuels known as cokes is a final carbon rich solid by product material that results from oil refining [57] Calcined petroleum coke CPC is the product of calcining PC at temperatures greater than 1200 °C to remove the volatile matter and decrease the porosity of PC as much as possible [58
The draft screening assessment focuses on 2 substances referred to collectively as the Petroleum Coke Group under the Chemicals Management Plan CMP These substances are coke petroleum and coke petroleum calcined also referred to as green coke and calcined coke respectively
Calcining of petroleum coke is done in the rotary kiln The kiln components consist of shell tires carrying stations seals refractory and a drive train which includes girth gear pinion speed reducer and variable speed motor Crushing and Screening Solutions Catalogue 51 Pages Nordberg® C120 Jaw Crusher Brochure 3 Pages
