| titleOfInvention | Procedure and apparatus for separating and purifying conjugated dienes |
| abstract | A method of separation and purification of conjugated dienes, which includes: a step of obtaining a first bottom product by extracting a mixture of hydrocarbons that includes a conjugated ethylene in an environment in the presence of a polymerization inhibitor that includes at least one of a nitrite and a di-lower alkylhydroxylamine defined by chemical formula 1: wherein R1 and R2 are linear, branched or cyclic alkyl groups having between 1 and 10 carbon atoms, respectively, in an extractive distillation column; a step of obtaining a second bottom product by distilling said first bottom product in a diffusion column; a step of recovering said second bottom product and supplying said extractive distillation column; a step of measuring the concentration of a polymerization inhibitor included in said second background product; and a control step for controlling the concentration of the polymerization inhibitor included in said second background product by modifying a supplied amount of the polymerization inhibitor to said extractive distillation column according to said measured concentration of the polymerization inhibitor. |
