preparation example Construction

[0029] The preparation method of the hydrocarbon oil iron remover of the present invention has no special requirements, as long as the components are uniformly mixed, the hydrocarbon oil iron remover can be obtained.

[0030] In the second aspect, the present invention also provides a method for removing iron from hydrocarbon oil, the method comprising: under the condition of electric desalting, contacting the hydrocarbon oil with a hydrocarbon oil iron remover to remove iron, the hydrocarbon oil iron remover is Hydrocarbon oil iron remover as mentioned above.

[0031] In the present invention, relative to 1 g of hydrocarbon oil, the amount of the hydrocarbon oil iron removal agent is preferably 10-1000 μg, more preferably 20-300 μg, and even more preferably 80-150 μg.

[0032] In the present invention, the electric desalination conditions preferably include: the electrostatic field temperature is 100-150° C., and the electric field strength is 200-2000 V / cm, more preferably 3...

Embodiment

[0036] The following examples will further illustrate the present invention, but do not limit the present invention thereby.

[0037] In the following examples and comparative examples:

[0038] Method for Determination of Iron Content in Oil Samples: GB / T 18608-2012

[0039] Iron removal rate=(original total iron content in hydrocarbon oil-iron content in oil sample to be tested after iron removal) / original total iron content in hydrocarbon oil×100%

preparation example 1

[0041] This preparation example is used to illustrate the hydrocarbon oil iron removal agent of the present invention.

[0042] With 5 parts by weight of citric acid, 15 parts by weight of YNE5211 (purchased from Nanjing Yinuoen Chemical Co., Ltd.), 30 parts by weight of O-isopropyl-N-ethylthiocarbamate, 12.5 parts by weight of Ethanol and 37.5 parts by weight of water were evenly mixed to obtain the hydrocarbon oil iron removing agent A1.

Abstract

The present invention relates to the field of hydrocarbon oil deferrization, and discloses a hydrocarbon oil deferrization agent, which comprises an organic acid, a polyether modified silicone oil, a thiamine ester and / or sulfurnitride ester, and a solvent. The invention further discloses a hydrocarbon oil deferrization method, which comprises that hydrocarbon oil contacts a hydrocarbon oil deferrization agent under an electrical desalting condition, wherein the hydrocarbon oil deferrization agent is the hydrocarbon oil deferrization agent of the present invention. According to the present invention, the hydrocarbon oil deferrization agent has the good removing effect for the iron in the hydrocarbon oil, is suitable for the high iron content hydrocarbon oil, can effectively remove the oil-soluble iron and the non-oil-soluble iron in the hydrocarbon oil, and cannot cause the local enrichment of the metal in the after-removing hydrocarbon; and the deferrization agent has characteristics of low consumption, good effect and simple use, can achieve the efficient iron removal while the desalting and the dehydrating are performed through the existing electric desalting process condition, and is easy to industrially promote and apply.

Description

technical field [0001] The invention relates to the field of hydrocarbon oil deironing, in particular to a hydrocarbon oil deironing agent and a method for using the hydrocarbon oil deironing agent to carry out hydrocarbon oil deironing. Background technique [0002] In recent years, with the development of unconventional energy sources such as tight oil and shale oil, and the continuous increase in the processing of low-quality crude oil and residual oil, the metal content in hydrocarbon oil has increased significantly, and the harm to subsequent processing and use has become increasingly prominent. Among them, iron has a greater poisonous effect on catalysts in catalytic cracking units and heavy oil hydrogenation units, which can cause catalysts to stick and accumulate, resulting in catalyst structure damage, deactivation, abnormal fluidization, and even permanent poisoning. Iron can also promote atmospheric and decompression Corrosion of the distillation tower top and con...
