This invention discloses method and apparatus for separating butane and butylene. The method comprises: (1) pretreating the raw materials; (2) extraction-rectifying the heavy fractions separated from step 1; (3) extraction-rectifying the light-heavy fractions separated from step 1; (4) separating the heavy fractions and the extractant in a degasification column. The apparatus comprises a raw material pretreatment rectification column, a heavy fraction extraction rectification column, a light-heavy fraction extraction rectification column, and a degasification column. The method can effectively increase the yields and purities of the fractions separated from C4 raw materials, lower the consumption of the extractant, and effectively reduce the foaming in the extraction rectification columns. Besides, the operation is stable. When used to separate butane and butylene from C4 raw materials in oil refinery plant, the method can realize high yield and purity of butylene product, low consumption ...

The invention discloses a rotational inertia adjustable inertia friction welding counterweight disc, and provides an adjustable inertia disc device for an inertia friction welding machine, which comprises an inertia disc, a guide rail, a counterweight block, a ball screw, an inner ring and an outer ring. The inertia disc is not easy to disassemble due to overweight, so that the inertia disc serves as a fixed inertia disc; the guide rail is arranged on the inertia disc and is marked with accurate scales; the balancing weight is supported by the guide rail and serves as a main part for adjusting rotational inertia, and accurate movement and control of the position of the balancing weight are achieved through the ball screw. The outer ring is arranged at the outer ends of the balance weight disc and the guide rail and plays a role in protection, and the inner ring is installed on the balance weight disc and plays a role in supporting and protection. The guide rail, the balancing weight, the ...
