Problems solved by technology

Oily wastewater discharged into urban ditches will cause adverse effects on ditches, ancillary equipment and urban sewage treatment plants
[0005] In order to solve the problem of oily wastewater treatment in the process of petroleum refining, most of them use demulsifiers first, and then purify the water quality. The reaction time of the process is long, which affects the treatment rate of oily wastewater generated in the process of petroleum refining, and then affects the production. Life Efficiency, Great Inconvenience

Embodiment 1

[0020] A water purifying agent for petroleum refining waste water, in parts by mass, comprising the following substances:

[0021] 3 parts of propanol, 10 parts of isopropanol, 15 parts of sodium pentylnaphthalene sulfonate, 5 parts of sodium dodecylbenzene sulfonate, 50 parts of deionized water, 2 parts of methyl benzotriazole solution, triethylene Tetramine 1 part.

[0022] This kind of petroleum refinery waste water purifying agent is made by the following steps:

[0023] (1) Put propanol and isopropanol into the reaction kettle, stir evenly and heat up to 40-70°C;

[0024] (2) Add sodium pentylnaphthalenesulfonate to material (1), then add sodium dodecylbenzenesulfonate, and stir until dissolved;

[0025] (3) Add deionized water to material (2) and stir evenly, then add tolutriazole solution and stir evenly, finally add triethylenetetramine and stir for 20-40min;

[0026] (4) Cool the material (3) to normal temperature and then discharge, measure and pack the finished p...

Embodiment 2

[0029] A water purifying agent for petroleum refining waste water, in parts by mass, comprising the following substances:

[0030] 5 parts of propanol, 15 parts of isopropanol, 20 parts of sodium pentylnaphthalene sulfonate, 10 parts of sodium dodecylbenzene sulfonate, 60 parts of deionized water, 4 parts of methyl benzotriazole solution, triethylene Tetramine 2 parts.

Abstract

The invention discloses an oil refining waste water purifying agent, which comprises the following components in parts by weight: 3 to 10 parts of propyl alcohol, 10 to 20 parts of isopropyl alcohol, 15 to 25 parts of sodium amyl naphthalene sulfonate, 5 to 15 parts of sodium dodecyl benzene sulfonate, 50 to 70 parts of deionized water, 2 to 5 parts of a TTA solution, and 1 to 3 parts of triethylenetetramine. The water purifying agent has the advantages that raw materials are readily available, the ratio is scientific, and the product performance is excellent, and is mainly used for treating oily waste water generated by oil refining; and the scale is thoroughly dissolved, the infiltration capacity is strong, and the water resource environment is effectively protected.

Description

technical field [0001] The invention belongs to a water purifying agent, in particular to a water purifying agent for petroleum refining waste water, and belongs to the technical field of chemistry and chemical engineering. Background technique [0002] Oily wastewater comes from a wide variety of sources. In addition to a large amount of oily wastewater discharged from oil extraction and processing industries, there are solid fuel thermal processing, wool washing wastewater in the textile industry, tanning wastewater in light industry, railway and transportation industries, slaughtering and food processing, and turning processes in the machinery industry. Emulsion in etc. Among them, the oily wastewater discharged from the petroleum industry and solid fuel thermal processing industry is the main source. [0003] The oily wastewater in the petroleum industry mainly comes from the processes of petroleum exploitation, petroleum refining and petrochemical industry. The waste...
