Embodiment 1

[0048] Taking Minusanxian Qingrun as raw material, the agricultural spray oil is prepared through rectification-clay refining-air stripping, the steps are as follows,

[0049] (1) Distillation unit

[0050] Process description of A rectification unit: The hydrogenated light distillate oil is precisely cut using a three-tower process. The specific process is: the raw material enters the rectification tower I to cut light components after heat exchange, and adopts decompression operation to control the pressure at the top of the tower at -90KPa (G). Distillation tower I top reflux controls rectification tower I top temperature 237 ℃, and the other way is sent out as light components after being cooled. Control the initial boiling point of the bottom distillate ≮354℃, as the raw material of the rectification tower II.

[0051] Rectification column II adopts decompression operation, and the control tower top pressure is at -90KPa (G). The tower top oil is divided into two paths...

Embodiment 2

[0062] The analysis data of the sample obtained after rectification-clay refining-air stripping with Jiansixian Qingrun as the raw material is shown in Table 3. The preparation method is the same as in Example 1.

Abstract

The invention discloses a green environmental-protection agricultural spraying oil and a preparation method thereof. According to the present invention, the light and wet hydrogenation distillate in the Jinan refinery heavy base oil bright oil project process is used as a raw material, and further precision fractionation-white clay refining-steam stripping treatment is performed to produce the environmental-protection agricultural spraying oil product, wherein the environmental-protection agricultural spraying oil meets the green environmental protection requirement, can meet the FDA certification requirement, and has advantages of high saturated hydrocarbon content, colorlessness, excellent light stability, excellent thermal stability, extremely low sulfur nitrogen content, no aromatic hydrocarbon, no harmful solvent, narrow distillation range, and good effect.

Description

technical field [0001] The invention relates to a green and environment-friendly agricultural spray oil and a preparation method thereof, belonging to the technical field of petrochemical products. Background technique [0002] Spray fertilization is one of the most common and efficient methods of topdressing in modern agriculture. The spray method is to mix the preparation containing oil, emulsifier and active ingredients of pesticides with a certain amount of water to prepare a uniform emulsion liquid, and use a sprayer to make the liquid form tiny droplets and spray it on the surface of the crops. Due to the high coverage density of the mist droplets, and the spreadability and adhesion of the EC are good, it is not easy to be leached by rainwater, the residual effect is long, and the chances of pests and diseases contacting the pesticide increase, so the control effect is better. [0003] In recent years, ultra-low-volume spraying technology has been popularized and appl...
