Embodiment 1
[0014] Preparation of A pretreatment agent: Put 6g of dodecylbenzenesulfonic acid and 6g of 90% ethylene glycol solution into a container, stir and mix thoroughly to obtain the pretreatment agent.
[0015] B Pretreatment effect: Add 1000 grams of untreated waste liquid from the bottom of the coal-to-ethylene glycol rectification tower to a 2000ml beaker. It has been determined that the total content of ethylene glycol and diethylene glycol in the waste liquid is 82.66%, of which ethylene glycol Alcohol 40.23%, diethylene glycol 42.43%. Slowly add 12 grams of the pretreatment agent dropwise into the waste liquid at the bottom of the coal-to-ethylene glycol rectification tower under stirring and fully stir for ten minutes. The prepared sample remained unchanged for 480 hours, and the untreated sample began to aggregate from the surface after being placed for 10 minutes, and all aggregated into one within 2 hours. 1012 grams of the sample treated with the pretreatment agent was ...
Embodiment 2
[0017] A Preparation of pretreatment agent: Take 8.4g of hydroxyethylidene diphosphoric acid and 8.4g of 90% ethylene glycol solution into a container, stir and mix thoroughly to obtain the pretreatment agent.
[0018] B Pretreatment effect: Add 600 grams of untreated waste liquid from the bottom of the coal-to-ethylene glycol rectification tower to a 1000ml beaker. It has been determined that the total content of ethylene glycol and diethylene glycol in the waste liquid is 75.17%, of which ethylene glycol Alcohol 38.39%, diethylene glycol 36.78%. Slowly add 9 grams of the pretreatment agent dropwise to the waste liquid at the bottom of the coal-to-ethylene glycol rectification tower under stirring and fully stir for 30 minutes. The prepared sample remained unchanged for 1080 hours, and the untreated sample began to aggregate from the surface after being placed for 10 minutes, and all aggregated into one within 2 hours. 609 grams of the sample treated with the pretreatment ag...
Embodiment 3
[0020] A Preparation of pretreatment agent: Put 5.1g of dodecylsulfonic acid and 5.1g of 90% ethylene glycol solution into a container, stir and mix thoroughly to obtain the pretreatment agent. ,
[0021] B Pretreatment effect: Add 300 grams of untreated waste liquid from the bottom of the coal-to-ethylene glycol rectification tower to a 500ml beaker. It has been determined that the total content of ethylene glycol and diethylene glycol in the waste liquid is 80.51%, of which ethylene glycol Alcohol 39.85%, diethylene glycol 40.66%. Slowly add 3.5 grams of the pretreatment agent dropwise into the waste liquid at the bottom of the coal-to-ethylene glycol rectification tower under stirring and fully stir for 45 minutes. The prepared sample remained unchanged for 1500 hours, and the untreated sample began to aggregate from the surface after being placed for 10 minutes, and all aggregated into one within 2 hours. 303.5 grams of the sample treated with the pretreatment agent was ...
