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...

[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...

Abstract

The invention discloses a mineral oil waste treatment process: (1) processing of chemical agents: heating to 400 DEG C with a demulsifier, polyacrylamide, cassava acetylated distarch adipate starch and sodium silicate to dissolve and react for 1 h so as to form a transparent liquid, and barreling for later use; (2) putting mineral oil waste into a heating tank, adding a medicament according to the ratio of 1 ton of the mineral oil waste to 0.5% of the medicament, heating to about 80 DEG C and fully stirring, demulsifying and decomposing the mineral oil waste, precipitating for 2 h, extracting crude oil, extruding wastewater and impurities by a filter press, filtering out moisture, and forming powdery solids from the impurities. Oil and impurities processed by the technology are all tested through a professional testing agency and all reach the discharge standard of national requirements.

Description

technical field [0001] The invention relates to an environmental protection treatment process for mineral oil waste, belonging to the technical field of environmental protection. Background technique [0002] According to the state's control of environmental pollution, vigorously promote environmental protection awareness, implement energy conservation and emission reduction policies, improve health levels, and enable people to have a fresh living environment. Reducing emissions and saving energy is the top priority at present, and must be paid attention to and put into action. [0003] Formation of mineral oil waste: [0004] Various oil fields and oil production plants across the country produce a large amount of mineral oil waste in the process of drilling and production and in the process of petroleum refining. Mineral oil waste mainly includes oil sludge, organic mud, oil sand, and sewage. %, impurity about 40%, sewage about 20%, ash about 10%. [0005] Hazards of mi...
