摘要
裂解制乙烯和催化裂化生成的Ｃ３液化气量均较大，进行化工利用有很好的经济效益。用主辅精馏塔对Ｃ３液化气进行分离，回收出丙烯，剩下的丙烷则作为裂解制乙烯的原料是适宜的回收方案，具有投资省和节能等特点。
Utilizing a large
quantity of liquefied petroleum gas (C 3 LPG) by chemical technology will bring a considerable
economic benefit to the enterprise. Propylene is retrieved after separating C 3 LPG by the primary
and auxiliary distillation columns. Propane of the tower bottoms is used as cracking stock for
producing ethylene .It is a suitable recovery program, especially for saving the investment and the
energy.
