Ramsbottom Carbon Residue Apparatus

The Ramsbottom Carbon Residue Apparatus is used to determine the carbon residue of an oil and other non volatile petroleum products, left after evaporation and pyrolysis according to ASTM D524. 

This measurement is vital in understanding the deposit-forming tendencies of fuels and lubricating oils.

Product Overview

The Ramsbottom Carbon Residue Apparatus is a thermostatically controlled coking furnace for five samples. The cast iron block type furnace rapidly reaches the standard test temperature of 550°C and controls with ±1°C stability.

Microprocessor temperature control:

  • with digital display
  • overtemperature cut-off
  • °C/°F switchable digital setpoint and display.
  • Heavily insulated stainless steel cabinet with three layer refractory top provides excellent heat retention.
  • Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options.
  • Conforms to ASTM D524 and related specifications
 

The operator and equipment are both protected by an overtemperature control circuit which automatically interrupts power to the unit should block temperature exceed the programmed cut-off point.

The apparatus is used to determine the ‘carbon residue’ remaining after evaporation and pyrolysis of the sample oil in the Ramsbottom furnace. It can also be used to provide an indication of the deposit forming tendencies of fuels.

About the Ramsbottom Carbon Residue Apparatus

The Ramsbottom Carbon Residue instrument is a thermostatically controlled coking furnace for five samples.

The cast iron block type furnace rapidly reaches the standard test temperature of 550°C and this is controlled with ±1°C stability.

The instrument has in-built safety features that protect both the operator and equipment: this overtemperature control circuit automatically interrupts power to the unit if the block temperature exceeds the programmed cut-off point.

The heavily insulated stainless steel cabinet has a three layer refractory top which provides excellent heat retention and so reduces power costs.
