APPARATUS AND METHOD FOR DETERMINING AND CONTROLLING THE HYDROGEN-TO-CARBON RATIO OF A PYROLYSIS PRODUCT LIQUID FRACTION

摘要

A PROCESS AND APPARATUS FOR DETERMINING THE HYDROGEN-TO-CARBON RATIO OF THE LIQUID FRACTION OF A PYROLYSIS PRODUCT BY DETERMINING THE HYDROGEN-TO-CARBON RATIO OF THE PYROLYSIS PRODUCT GAS FRACTION AND SUBTRACTING THE THUS DETERMINED VALUE FROM THE DETERMINED HYDROGEN-TO-CARBON OF THE HYDROCARBON FEED TO THE PYROLYSIS FURNACE. THE DETERMINED VALUE FOR THE HYDROGEN-TO-CARBON RATIO OF THE LIQUID FRACTION IS USED AS A MEASURE OF CRACKING SEVERITY AND IN THE CONTROL OF THE PYROLYSIS FURNACE IN RESPONSE TO DIFFERENCES BETWEEN THE DESIRED AND ACTUAL HYDROGEN-TO-CARBON RATIO OF THE LIQUID FRACTION.
