Process and apparatus for the separation of hydrocarbons with simultaneous production of acetylene
Abstract
Abstract A PROCESS AND APPARATUS FOR SEPARATING ACETYLENE-RICH GASEOUS MIXTURE CONSISTING ESSENTIALLY OF C1-TO C5-HYDROCARBONS AND INERT GASES. THE MIXTURE IS PASSED THROUGH A PLURALITY OF PRELIMINARY COOLING STAGES OF DECREASING TEMPERATURE TO CONDENSE OUT THE HIGHER HYDROCARBONS AND FRACTIONS OF ACETYLENE AT EACH STAGE. THE MAJOR PORTION OF THE C2-HYDROCARBONS, INCLUDING THE REMAINING ACETYLENE, IS CONDENSED OUT IN A LOW TEMPERATURE COOLING STAGE. THE CONDENSATES ARE FURTHER SEPARATED IN SEPARATING AND LOW TEMPERATURE SCRUBBING STEPS TO PRODUCE ACETYLENEFREE AND ACETYLENE-ENRICHED FRACTIONS. ENGINE EXPANSION OF THE METHANE AND INERT GASES AND THROTTLE EXPANSION OF A LIQUID FRACTION IS UTILIZED TO PRODUCE A PORTION OF THE REFRIGERATION REQUIRED FOR THE SEPARATION PROCESSES.
