Embodiment

[0041] The following non-limiting examples are included purely by way of illustration of the presently disclosed subject matter. The following example is using ASPEN Results of steady-state computer simulations performed for versions 2006.5 and V8.2.

[0042] Example 1 - Parameters within an exemplary system

[0043] provided the basis figure 1 system 100 . The parameters of the system 100 are shown in Table 1.

[0044] Table 1

[0045]

[0046]

[0047] The reboiler duty and condenser duty values ​​in Table 1 measure the energy input to the second distillation column 102 (main distillation column). These values ​​demonstrate that systems and methods in accordance with the presently disclosed subject matter can be energy efficient.

Embodiment 2

[0048] Embodiment 2 - the method for purifying 1,3-butadiene

[0049] according to figure 1 A crude 1,3-butadiene stream of 15750 kg / h is fed into the system 100 . The crude 1,3-butadiene stream had the composition shown in Table 2.

[0050] Table 2

[0051]

[0052]

[0053] Crude 1,3-butadiene was supplied in liquid form to the twelfth theoretical plate of the first distillation column 101 having 30 theoretical plates via the 1,3-butadiene feed line 107 . The top vapor stream of the first distillation column 101 is fed into the seventeenth theoretical stage of the second distillation column 102 via the third interconnection 105 . The bottoms stream of the first distillation column 101 is fed into the forty-sixth theoretical plate of the second distillation column 102 via the fourth interconnection 106 . A part of the liquid reflux from the second distillation column 102 is taken from the seventeenth theoretical stage and fed to the first theoretical stage of the fi...

Abstract

Systems for purifying 1,3-butadiene are provided. An exemplary system includes a first distillation column, a second distillation column, and interconnections between the first and second distillationcolumns. A first interconnection can feed a liquid stream from the second distillation column to the first, while a second interconnection can feed a gas stream from the second distillation column tothe first. Processes for purifying 1,3-butadiene are also provided.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to US Provisional Application No. 62 / 245,333, filed October 23, 2015. The contents of the cited applications are incorporated by reference into this application. technical field [0003] The presently disclosed subject matter relates to methods and systems for purifying 1,3-butadiene. Background technique [0004] 1,3-Butadiene is a very valuable hydrocarbon. Also known as buta-1,3-diene, erythrene, and vinylethylene, it is the simplest 1,3-diene compound. 1,3-Butadiene can be used as a monomeric starting material for the preparation of various polymers, including synthetic rubber. 1,3-Butadiene can be used as a raw material in the production of adiponitrile. 1,3-Butadiene can also be used as a substrate in certain Diels-Alder reactions. [0005] 1,3-Butadiene can be obtained from different sources, including the dehydrogenation of n-butane and the reaction of ethanol. ...
