Embodiment 1

[0024] The composite demetallizer consists of:

[0025] (a) using toluenesulfonic acid as the metal removal agent, its consumption is 4 times of the weight of calcium in the hydrocarbon oil;

[0026] (b) a mixture of glycolic acid and fructose acid is used as an auxiliary agent, wherein the consumption of glycolic acid is 2 times of the weight of calcium in the hydrocarbon oil, and the consumption of fructose acid is 0.8 times of the weight of calcium in the hydrocarbon oil;

[0027] (c) 30 ppm BP2040 demulsifier by weight of hydrocarbon oil.

[0028] The method for removing metal from hydrocarbon oil by using the above-mentioned composite demetallizer is as follows:

[0029] The crude oil from Africa with a calcium content of 280ppm was used as the raw material hydrocarbon oil. After fully mixing 70g of the crude oil, 15g of distilled water, and the above-mentioned composite demetallization agent (during the operation, the demetallization agent, auxiliary agent, water, and ...

Embodiment 2

[0031] The difference from Example 1 is that the raw material hydrocarbon oil is a mixed crude oil from Africa with a calcium content of 75 ppm.

Embodiment 3

[0033] The composite demetallizer consists of:

[0034] (a) using benzenesulfonic acid as the metal removal agent, its consumption is 0.8 times of the weight of calcium in the hydrocarbon oil;

[0035] (b) using lactic acid as an auxiliary agent, its consumption is 4 times of the weight of calcium in the hydrocarbon oil;

[0036] (c) 20 ppm of TP9603 demulsifier by weight of hydrocarbon oil.

[0037] The method for removing metal from hydrocarbon oil by using the above-mentioned composite demetallizer is as follows:

[0038] Dagang crude oil with a calcium content of 64ppm was used as the raw material hydrocarbon oil. After fully mixing 80g of the crude oil, 10g of distilled water, and the above-mentioned composite demetallization agent (during the operation, the demetallization agent, auxiliary agent, water, and demulsifier can be added to the crude oil separately or simultaneously, and can be added in any order), Pour into a conical glass desalination tube, keep the tempe...

Abstract

The invention discloses a complex demetalation agent used for hydrocarbon ils. The comprised components and their weight are as follows: (a) demetalation agent with its weight 0.2- 10 times of that of calcium in hydrocarbon ils, said demetalation is alkylbenzene sulfonate; (b) adjuvant with its weight 0.2- 10 times of that of calcium in hydrocarbon ils, said adjuvant is one or combination of levulinate, glycolic acid, lactic acid, disodium editate, complexon, gluconic acid, tartaric acid or citric acid; (c) demulsifying agent with its weight being 2- 100 ppm of hydrocarbon ils. The invention aslo discloses a method for remove metal from hydrocarbon ils by using said demetalation, which is can be used in demulsifying agent process in oil field or on normal electric desalting device. The invention is characterized by easy get raw material, simple operation, high demetalation rate, and wide suitability for raw hydrocarbon ils.

Description

technical field [0001] The invention relates to a preparation for processing hydrocarbon oil and a processing method for hydrocarbon oil, in particular to a composite demetallizing agent for hydrocarbon oil and a method for removing metal. Background technique [0002] Crude oil is mainly composed of different hydrocarbon compounds and their derivatives, which also contains some metal elements. For crude oil extracted from different oil fields, different oil regions and different oil wells, there are certain differences in the types, contents and occurrence states of metal elements contained in them. In addition, as crude oil resources are exploited in large quantities, more and more heavy oils are extracted, and the content of metals in some heavy oils, such as calcium, magnesium, iron, etc., has increased significantly, so the crude oil processing belt More adverse effects came. Studies have shown that the increase of calcium, magnesium and iron content in crude oil will...
