Embodiment 1
[0026] Preparation of tapioca acetylated distarch adipate starch:
[0027] Weigh a certain amount of adipic anhydride and 20mL acetic anhydride and put them in a stoppered Erlenmeyer flask, dissolve them evenly in a water bath at 60°C, weigh 500g of tapioca starch (water content 12-14%) and dissolve them in pure water. Make starch milk with a concentration of 40%, raise the temperature to 30°C, adjust the pH of the starch milk to 8.0-8.5 with 3.0% sodium hydroxide solution, and add the above-mentioned medicines dropwise within a certain period of time at room temperature until the pH remains unchanged , adjust the pH of the system to about 5.0-5.5 with dilute hydrochloric acid (10%), terminate the reaction, vacuum filter, dehydrate, wash with water three times, and dry at normal temperature to obtain cassava acetylated distarch adipate starch.
Embodiment 2
[0029] A mineral oil waste treatment process:
[0030] (1) Processing chemicals: According to the weight fraction, use 50 parts of SPX-8603 demulsifier, 35 parts of polyacrylamide, and 8 parts of sodium silicate to heat to 400 degrees to dissolve and react for 1 hour to form a transparent liquid and pack it into a barrel for later use ;
[0031] (2) First put the mineral oil waste into the heating tank, add 0.5% of each ton of mineral oil waste into the medicament and heat it to about 80 degrees and stir fully to make the mineral oil waste demulsify, decompose, and precipitate 2 The crude oil, waste water and impurities are squeezed out through the filter press in an hour, and the water is filtered out, and the impurities form powdery solids.
[0032] Comparison of parameters before and after mineral oil waste treatment:
[0033] The oil and impurities processed by this technology have been tested by professional inspection agencies, and all of them have reached the emission...
Embodiment 3
[0039] A mineral oil waste treatment process:
[0040] (1) Processing chemicals: According to the weight fraction, use 50 parts of ZSP9201 demulsifier, 35 parts of polyacrylamide, and 8 parts of sodium silicate to heat to 400 degrees to dissolve and react for 1 hour to form a transparent liquid and pack it into a barrel for later use;
[0041] (2) First put the mineral oil waste into the heating tank, add 0.5% of each ton of mineral oil waste into the medicament and heat it to about 80 degrees and stir fully to make the mineral oil waste demulsify, decompose, and precipitate 2 The crude oil, waste water and impurities are squeezed out through the filter press in an hour, and the water is filtered out, and the impurities form powdery solids.
[0042] Comparison of parameters before and after mineral oil waste treatment:
[0043] The oil and impurities processed by this technology have been tested by professional inspection agencies, and all of them have reached the emission st...
