Analysis for adaptability of reducing LPG C2 content in absorbing-stabilizing system
Fenglin Huang, Xueli Qu, Xuan Tang · 2011
According to the low yield of propylene existing in gas fractionation device due to higher C2content 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 C2content (no more than 0.1 %χ) in LPG, fulfilling the technological requirements of double tower process for gas fractionation device.
