Summary:Systems and methods for processing C3 and C4 hydrocarbon mixtures are disclosed. The C3 and C4 hydrocarbon mixture is separated to remove propane from the C4 hydrocarbons. The resulting C4 hydrocarbons are then treated in an isomerization unit to produce additional isobutane. Isobutane from the isomerization unit effluent is dehydrogenated in a dehydrogenation unit to produce isobutene. And reacting the obtained isobutene with alkanol to generate alkyl tert-butyl ether. 公开了用于处理C3和C4烃混合物的系统和方法。分离C3和C4烃混合物，以从C4烃中除去丙烷。然后将所得的C4烃在异构化装置中处理以生成另外的异丁烷。异构化装置流出物的异丁烷在脱氢装置中脱氢以生成异丁烯。所得的异丁烯与烷醇反应生成烷基叔丁基醚。
