Analysis for adaptability of reducing LPG C 2 content in absorbing-stabilizing system

According to the low yield of propylene existing in gas fractionation device due to higher C 2 content in LPG, the factors affecting on LPG quality in the absorbing-stabilizing system were analyzed. Some technics such as optimization of operating condition and energy-efficient process were adopted to intensify the separation effect, offering the advice with lower C 2 content (no more than 0.1%χ) in LPG, fulfilling the technological requirements of double-tower process for gas fractionation device.
