Automated Micro Carbon Residue Tester ACR-M3

ACR-M3 is a tester to be used for the determination of the amount of carbon residue formed after evaporation and pyrolysis of petroleum material under certain conditions and is intended to provide some indication of the relative coke forming tendency of such materials.

A weighed quantity of sample is placed in a glass vial and heated to 500℃ under an inert (nitrogen) atmosphere in a controlled manner for a specific time. The sample undergoes coking reactions and volatiles formed are swept away by reported as a percent of the original sample as “carbon residue (micro).” Micro Method offers advantages of better control of test conditions, smaller samples, and less operator attention compared to Conradson Carbon Residue test to which it is equivalent. Up to twelve samples may be run simultaneously including a control sample.

SMALL SAMPLE: Test can be run with a small quantity of sample (0.15 to 1.5g for small vials, 3.0g for medium vials and 5.0g for large vials, depending on carbon residue content).

EASY OPERATION: Test automatically proceeds exactly as prescribed by simply pushing the START switch. Pressure controller (2nd stage regulator) and solenoid valve supply constant pressure. No fine tuning is required after test starts. The buzzer sounds intermittently for 10 seconds when the process is finished.

Equipo automatico para determinacion de residuo de carbon micro ACR-M3

EL ACR-M3 es un equipo usado para la determinacion de la cantidad de residuo de carbon formado despues de la evaporacion y pirolisis de un derivado de petroleo bajo algunas condiciones controladas, esto permite medir la tendencia a la formacion de coque en tales materiales en concordancia con el metodo ASTM D4530.

Inicialmente, la muestra es destilada siguiendo un procedimiento similar al metodo ASTM D86 pero es interrumpido para tomar el corte final mas pesado, una muestra de este corte es introducida y pesada en una vial de vidrio para ser calentada a 500 °C en una atmosfera de nitrogeno. La muestra es por lo tanto sometida a un proceso de coquizado y los volatiles formados son barridos por el nitrogeno. Finalmente por diferencia de peso es posible obtener el resultado de residuo de carbon. Este metodo representa una alternativa automatica mucho mas facil y segura en comparacion con la clasica tecnica Conradson.
