Example Embodiment

[0021] Example 1:

[0022] Such as figure 1 As shown, a process for environmentally friendly treatment of industrial residues and waste tar from the production of acetylenic alcohol products includes the following steps:

[0023] S1. Take industrial residues and waste tar from the production of methylbutynol and dimethylhexynediol products in a condensation storage tank, and add a condensation agent. The amount of condensation agent added is 0.01% of the total weight of the industrial residue and waste tar. Mix well and let stand at constant temperature for more than 30 days;

[0024] S2. Add adjusting stabilizer. The amount of adjusting stabilizer added is 0.01% of the total weight of industrial residues and waste tar. The distillation temperature is controlled to 0℃~200℃, and the distillation pressure is 0MPa~-0.85MPa. Perform distillation and collect different temperatures. Point fractions, get liquid crude acetylenic alcohol products, solid acetylenic alcohol crude products and ...

Abstract

The invention discloses a technique for environmentally friendly treating industrial residue and waste tar from production of alkynol products. The technique comprises: first, adding a condensing agent to the residue and waste tar from the production of alkynol products, mixing well, allowing the mixture to stand at a constant temperature for 30 days and longer, adding an adjusting stabilizer, carrying out distilling, collecting fractions with different temperatures, cooling and crystallizing the fractions with the different temperatures, and separating a liquid phase and crystal solid alkynolproducts; dewatering the liquid phase, and carrying out distilling to obtain a solvent or liquid material with a low boiling point, liquid alkynol products with a medium boiling point, and a heavy component material with a high boiling point; adding water to dissolve the solid alkynol products, stirring, carrying out distilling, removing part of water, and cooling and recrystallizing to obtain the solid alkynol products with water, and drying to obtain the fine solid alkynol products. The technique has the advantages that the technique is energy efficient and environmentally friendly, waste is turned into wealth, residue and residual liquid are efficiently recycled, recycling of industrial materials is improved, and no residue is discharged so that environmental pollution is relieved.

Description

technical field [0001] The invention relates to the technical field of processing chemical residues and waste tar, in particular to an environmentally friendly and harmless process for treating industrial residues and waste tar produced in the production of acetylenic alcohol products. Background technique [0002] In the production process of acetylenic alcohol products, a large amount of residue and waste tar will be produced, and the residue and waste tar will contain a large amount of raw materials such as intermediates of acetylenic alcohol products. At present, the industrial residues and waste tar produced are all incinerated, which not only causes economic losses, but also pollutes the environment. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention provides an environmentally friendly and harmless process for the industrial residue and waste tar produced by the production of acetylenic alcohol products...
