Conradson carbon residue - Wikipedia
Conradson carbon residue, commonly known as "Concarbon" or "CCR", is a laboratory test used to provide an indication of the coke-forming tendencies of an oil. Quantitatively, the test measures the amount of carbonaceous residue remaining after the oil's evaporation and pyrolysis .
NOTE 1—The term carbon residue is used throughout this test method to designate the carbonaceous residue formed after evaporation and pyrolysis of a petroleum product under the conditions specified in this test method. The residue is not composed entirely of carbon, but is a coke which can be further changed by pyrolysis. The term carbon ...
D189 Standard Test Method for Conradson Carbon Residue of …
2024年5月7日 · 1.1 This test method covers the determination of the amount of carbon residue (Note 1) left after evaporation and pyrolysis of an oil, and is intended to provide some indication of relative coke-forming propensities. This test method is generally applicable to relatively nonvolatile petroleum products which partially decompose on distillation ...

2023年8月19日 · The Conradson Carbon Residue (CCR) test is a method used to determine the amount of carbon residue left behind when a sample of crude oil is distilled at high temperatures. The test provides an indication of the coke-forming capacity of petroleum fraction or crude oil .
Carbon Residue Estimation and Control in Vacuum Towers — …
2017年6月27日 · Ramsbottom Carbon Residue (RCR), Conradson Carbon Residue (CCR), Micro Carbon Residue (MCR) are the most commonly used indexes for estimation of carbon residue. Conradson Carbon Residue is commonly called as Concarbon or CCR is analyzed in the laboratory which provides a coke forming tendency of the oil.
Delayed Coking | FSC 432: Petroleum Refining - John A. Dutton e ...
These variables are selected based on feed properties such as the characterization factor, asphaltene content, and Conradson Carbon Residue (CCR) to ensure that coking in tubular heaters is minimized, and liquid product yield is maximized.
Estimation of Properties of Crude Oil Residual Fractions Using ...
2007年3月1日 · Knowledge of certain properties of a crude oil such as saturates, aromatics, resins, and asphaltenes (SARA) contents, Conradson carbon residue (CCR), ultimate analysis (CHNS), density, and molecular weight (MW) is useful for the characterization of the oil.
Carbon residue and coking - LEARN OIL ANALYSIS
2022年7月27日 · There are a few methods for measuring carbon residue. The classic two are Conradson and Ramsbottom methods, but both have largely been replaced by the newer and less messy for lab staff microcarbon method. The microcarbon method gives comparable data to the conradson method too which means there is no step change in data when switching.
Ramsbottom carbon residue - Wikipedia
Ramsbottom carbon residue (RCR) is well known in the petroleum industry as a method to calculate the carbon residue of a fuel. The carbon residue value is considered by some to give an approximate indication of the combustibility and deposit forming tendencies of the fuel.

2019年7月3日 · Micro Carbon Residue (MCR) is measured by the Conradson carbon (CCR or ConCarbon) method ASTM D189. MCR is a measurement of hydrocarbon mixtures’ tendency to leave carbon deposits (coke) when burned as fuel or subjected to intense heat in a processing unit such as a catalytic cracker.
