Embodiment 1～6

[0026] This group of embodiment adopts actual crude oil sample, example Liaohe high acid value heavy crude oil, specific gravity 0.92 g / cm 3 , colloid 13%, Ca content 46.3ppm; Dagang crude oil (calcium content 104ppm); Shengli Oilfield (calcium content 33.67ppm); Luning pipeline oil (calcium content 26.42ppm), Iranian dirty oil (calcium content 69.7ppm), Iranian residual oil (calcium content 241.1ppm).

[0027] Mix deionized water, 10ppm BP2040 demulsifier (produced by Henan Luoyang Mengjin Petrochemical Anticorrosion Material Factory), different concentrations of chelating agents, precipitants and different concentrations of polyethylene glycol, with 70 grams of crude oil with different calcium contents, and mix them at 60 °C , Under 1000 volts / centimeter electric field effect 6 minutes, separate crude oil and water then, measure the calcium content in the crude oil after taking off, wherein chelating agent is 8-hydroxyquinoline among the embodiment 1~6, and its result is lis...

Embodiment 7

[0036] By each step and condition of embodiment 1, just do not add demulsifier, its result decalcification rate is 88.6%.

Embodiment 8

[0038] According to the steps and conditions of Example 1, only the demulsifier is changed into ethylene glycol methyl ether, and the chelating agent is changed into 2,3,6,7-4 methyl-8 hydroxyquinoline, and the decalcification rate of the result is 89.1 %.

Abstract

A composition for removing metals from masrolar D contains chelating agent, precipitant, optional surfactant and demulsifier, and at least one of mono-alcohol or biol polymer, quaternary ammonium salt, quaternary phosphonium salt and crown ether.

Description

technical field [0001] The present invention relates to compositions for demetalling hydrocarbon oils. Background technique [0002] In recent years, with the development of oil extraction technology, a large amount of heavy crude oil has been extracted. The metal content in these crude oils, especially the content of some alkaline earth metals such as Ca has increased greatly, and their influence on crude oil processing has been paid more and more attention by people. Studies have shown that the increase of Ca content in raw oil will significantly reduce the molecular sieve and matrix area of ​​the catalyst, which will directly affect the activity of the catalyst. In recent years, some refineries refining high-Ca crude oil have experienced poisoning and deactivation of catalytic cracking catalysts, which not only greatly reduces the yield of light oil, but also affects the quality of downstream residual oil, greatly affecting the refinery's crude o...
