Embodiment 1

[0030] Put 80 tons of butyl-octyl alcohol waste oil into the rectification reactor, heat it up to 80°C-120°C with steam, fractionate it according to the boiling point of different substances under normal pressure, and send the fractionated fraction to the intermediate tank; among them, the mixed alcohol 11 tons, 13 tons of heavy oil, and gas containing hydrocarbons will be emitted at the same time, and sent to the incinerator for incineration. From the mixed alcohol, 9 tons of n-butanol and 4 tons of isobutanol are obtained, and the heavy oil is mainly C8-C12 alkanes, which can be used as boiler fuel.

[0031] Then add 10 tons of turpentine, 25 tons of octanol and 11 tons of sodium hydroxide to the rectification reaction kettle to participate in the compounding, and control the reaction temperature at about 100°C, keep the normal pressure and constant temperature for 5 to 6 hours, and get the semi-finished product;

[0032] Then send the reaction semi-finished product in the r...

Embodiment 2

[0035] Put 85 tons of 2-PH waste oil into the rectification reactor, heat it with steam to 80°C~120°C, fractionate according to the boiling point of different substances under negative pressure (-0.095KPa), and send the fractionated fraction to the intermediate tank; 11.5 tons of mixed alcohol and 13.2 tons of heavy oil will be obtained by fractional distillation. At the same time, gas containing hydrocarbons will be discharged and sent to the incinerator for incineration.

[0036] Then add 11 tons of turpentine, 28 tons of octanol and 10 tons of sodium hydroxide to the rectification reaction kettle to participate in the compounding, and control the reaction temperature at about 100°C, keep the normal pressure and constant temperature for 5 to 6 hours, and get the semi-finished product;

[0037] Then send the reaction semi-finished product in the rectification reaction kettle to the semi-finished product separation tank, adjust the pH to 7-8 with 30% sodium hydroxide solution, ...

Abstract

The invention provides a resourceful treatment method for butanol-octanol waste oil and 2-PH waste oil, which can effectively recover useful compositions in the waste oil to produce an ore flotation agent and obtain a product with high added value, and has good economical benefit. In the method, the butanol-octanol waste oil is fractionized under normal pressure or pressure reduction to obtain mixed alcohol and heavy oil, and then auxiliary materials such as octanol are added to compound to obtain a flotation agent product. Industrial waste gas produced during wastewater esterification and fractionization processes is cleaned and then is sent into the prior incinerator for incineration treatment along with waste residues produced by neutralization and separation after the compounding, and heat energy in flue gas is recovered to produce steam for a production device for use. A production technology does not produce production sewage.

Description

technical field [0001] The invention relates to a method for treating butyl-octyl alcohol waste oil and 2PH waste oil, which is used for resource recovery and utilization through resource treatment, and belongs to the technical field of chemical industry. Background technique: [0002] At present, the butanol-octyl alcohol waste oil and 2-PH waste oil produced by chemical enterprises are waste materials for production units, and it is difficult to dispose of them by themselves. Many companies use incineration to dispose of waste oil, which not only wastes energy, but also causes certain pollution. Contents of the invention [0003] Aiming at the above-mentioned technical situation, the present invention provides a resource recovery treatment method of butyl octanol waste oil and 2-PH waste oil, which can effectively recycle useful components in waste oil to produce ore flotation agent, and obtain high value-added products. It has very good economic benefits. [0004] The...
