Coke breeze is a carbonaceous backfill widely used to enhance the performances of impressed current groundbeds. Petroleum coke undergoes a thermal treatment process called “calcination” where it is heated at high temperatures in special ovens where most of the volatiles and the residual hydrocarbons are eliminated leaving a highpurity granular carbon.
Five Coke Breeze Backfills. Asbury 218L Backfill is an industry standard calcined petroleum coke. It is a perfect choice in situations where backfill must be top loaded. The density and angular nature of Asbury 218L allow it to settle quickly into position.
Petroleum coke breeze can be used in both conventional and deep anode grounded to lower the resistancetoearth and improve operating performance. The backfill has excellent pumping qualities and can be either mixed with water or installed as dry petroleum coke breeze, which is calcined to remove hydrocarbons and moisture.
A particularly attractive feedstock, petroleum coke (petcoke) is the solid carbon byproduct of the oil refining process. Asbury is a worldwide reliable source for both green and calcined petroleum coke (CPC) products. These highquality, nongraphitic carbons can be found in applications ranging from foundry products and wear moderators for PTFE compounds, to reducing agents and drilling ...
Sep 15, 2017· The materials include coke breeze, natural graphite and calcined petroleum coke. The purpose of carbonaceous backfill is to reduce the groundbed resistance and surface for the oxidation reaction. This prolongs the life of the anode.
Made from petroleum coke breeze, which is calcined to remove hydrocarbons and moisture, the backfill possesses a high fixed carbon content and an uncompact resistivity of ohmcm. Alcoke is processed on site and is available in three product grades ideal for different installation methods.

Loresco SC3® surface modified calcined petroleum backfill is designed specifically for demanding anode systems which mandate a low resistivity medium. SC3® is extremely pure and complies with regulations governing buried products.
LORESCO SC3® COKE BACKFILL Application Loresco SC3® surface modified calcined petroleum backfill is designed specifically for demanding anode systems which mandate a low resistivity medium. SC3® is extremely pure and complies with regulations governing buried products.
Welcome to the website of LORESCO® INTERNATIONAL, manufacturers of carbon backfill products for the cathodic protection and electrical grounding industries. This site contains information about our company and products, as well as a few tools designed to make your job a little easier.
Backfill should be petroleum coke calcined (heat treated) to remove all other petroleum products, other than carbon, and should be supplied in granular form. Lime in a proportion of 10% by weight of coke breeze should be added to the product. The proposed material should have the properties of Table
Cathodic protection (CP) anode beds are typically installed using carbonaceous backfill materials such as coal coke breeze, calcined petroleum coke breeze, or graphite carbonaceous backfills help reduce the contact resistance of the individual anodes in the anode bed by increasing the size of the anode.
Calcined. Calcined petroleum coke (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.
MATERIAL SAFETY DATA SHEET MSDS No.: 200C1 Calcined Petroleum Coke Revision No.: 4 Date: 11/04/04 Page 5 of 7 RCS COMPANIES PHYSICAL CHEMICAL PROPERTIES – SECTION 9 PRODUCT: Calcined Petroleum Coke General Information: Appearance Grey to black solid, may be in the form of a dust Odor Odorless
The final calcined product contains only a trace of volatile matter, and % sulfur, depending on the petroleum base used to make the coke. Calcined and green petroleum cokes are inherently low in ash constituents. The fixed carbon content of most calcined petroleum coke products ranges from approximately %.
The calcined petroleum coke breeze backfill around the anode makes the anode current be exhausted from the greatly increased surface, thus to reduce the anode resistance and consumption, thereby achieving cathodic protection, and greatly reducing the corrosion rate of the metal pipelines and components embedded in soils.
BACKFILL MATERIAL DATA CONSTRUCTION TYPE A general purpose coke breeze is for use in shallow horizontal and vertical ground beds (code CCBFGPCB) For deep well applications a special calcined petroleum coke breeze is available (code CCBFSCPCB). BACKFILL MATERIAL’S CODE CCBFGPCB CCBFSCPCB MATERIAL TYPE Assorted coke breeze
For deep well applications a special calcined petroleum coke breeze is available. Corrocont backfill coke mixes easily with water and provide homogenous environment for impressed current anodes deep or shallow and can substantially lower ground resistance by twenty, thirty, or even forty percent.
Types of materials use include coke breeze, calcined petroleum coke and natural graphite. The dual purpose of the carbonaceous backfill is to reduce the groundbed resistance by increasing the effective size of the anode and to provide a surface on which oxidation reactions could occur. The latter function prolongs anode life.
