Abstract

1452377 Fractional distillation with vapour compression BRITISH PETROLEUM CO Ltd 27 Feb 1975 [10 April 1974] 15913/74 Heading B1B [Also in Division C5] Fractional distillation is carried out by withdrawing an overhead vapour fraction from a column, compressing said fraction with increase in temperature whilst maintaining it in the vapour phase, exchanging the latent heat of condensation of the pressurised fraction with a distillation column stream, driving the compressor with a turbine using a vapour e.g. steam as motive fluid, exchanging the latent heat of condensation of the motive fluid exhaust vapour with a distillation column stream and recovering one or more streams as product from the distillation column. The separation of isoparaffins from naphtha is described.
