| titleOfInvention | A kind of method that by-product hydrochloric acid recycles in ADC foaming agents producing process |
| abstract | The invention discloses the method that by-product hydrochloric acid in a kind of ADC foaming agents producing process recycles, the pre-treatment step S2 of pre-treatment step S1, by-product hydrochloric acid including thick hydrazine hydrate, the primary neutralisation treatment step S3 of hydrazine hydrate solution, the desalination processing step S4 of two level hydrazine hydrate solution, biruea forming steps S5, ADC foaming agent forming steps S6.The by-product hydrochloric acid of step S6 outputs is recycled, hydrogen chloride gas is formed after step S2 processing, is passed through in step s3 in hydrazine hydrate solution, to remove substantial amounts of sodium carbonate in hydrazine hydrate solution, form and by-product hydrochloric acid is recycled.The present invention has handled the whereabouts problem of by-product hydrochloric acid, it is avoided to pollute the environment, and processing is realized to the sodium carbonate in hydrazine hydrate solution, and the main discarded object sodium chloride of formation can drain into salt pan, and the producing process of ADC foaming agents is more environmentally friendly.The treatment process of hydrogen chloride is simple in the present invention, and consume energy low, remarkable in economical benefits. |
