摘要： The present invention relates to a method of recovering an absorption solvent in a butadiene production process through oxidative dehydrogenation, the method including: a) transferring a light gas discharged from an upper portion of an absorption tower to a wash column; and b) recovering the absorption solvent included in the light gas by a solvent circulating in the wash column. Since an absorption solvent may be prevented from being introduced into a reactor, or being discharged to an outside of a system, economic efficiency of a butadiene production process is improved.

摘要： There are provided a dividing wall distillation column for producing high-purity acrylic acid, and a fractional distillation method using the same. The dividing wall distillation column includes a condenser, a reboiler and a main column having a dividing wall. Here, the main column is divided into a column-top zone, an upper feed zone, an upper outflow zone, a lower feed zone, a lower outflow zone and a column-bottom zone. Also, a crude acrylic acid raw material (F) flows in a middle inflow plate NR1 in which the upper feed zone and the lower feed zone come in contact with each other, a low boiling point component (D) flows out from the column-top zone, a high boiling point component (B) flows out from the column-bottom zone, and a middle boiling point component (S) flows out through a middle outflow plate NR2 in which the upper outflow zone and the lower outflow zone come in contact with each other. In this case, the middle boiling point component is acrylic acid. Accordingly, since one distillation column can be used to realize the same effect as that obtained from the use of two distillation columns, the dividing wall distillation column can have an effect of reducing the costs of equipment to produce high-purity acrylic acid, as well as an energy-reducing effect, compared to a conventional process system.

摘要： The present invention relates to a method for recycling energy in a butadiene preparation process using oxidative dehydrogenation, comprising the steps of: a) producing electricity by supplying, to a turbine, a part or all of a gas product discharged from a solvent absorption column; b) allowing the gas product, which has passed through the turbine, to pass through one or more device units comprising a heat exchanger; and c) injecting, into a reactor, the gas product having passed through the device units comprising a heat exchanger. The economical efficiency of a butadiene preparation process is improved by lowering the amount of pure energy required in the butadiene preparation process using oxidative dehydrogenation.
