Abstract
The invention discloses a preparation method for a water-based desulfurizing agent for high-sulfur crude oil, which belongs to the technical field of crude oil desulfurization in the petroleum industry. The high sulfur crude oil water-based desulfurizing agent is mainly composed of s-triazine and a derivative thereof, and alcohol amine, and assists with a buffering agent, an osmotic agent, an antifoaming agent, an antifreezing agent, and water. The content of s-triazine and its derivative account for 20-30%, the alcohol amine accounts for 5%-20%, the buffering agent accounts for 1-5%, the osmotic agent accounts for 1-2%, the antifoaming agent accounts for 0.01%-0.05%, the antifreeze agent accounts for 5-10%, and the balance is water. The method has the advantages of simple preparation process, high desulfurization activity of a working solution, large sulfur capacity, instantaneous desulfurization, irreversible desulfurization reaction, strong adaptability, and broad spectrum application.
Description
technical field [0001] The invention belongs to the technical field of petrochemical crude oil desulfurization, in particular to a water-based desulfurizer for high-sulfur crude oil and a preparation method thereof. technical background [0002] With the development of the economy, my country's energy demand continues to grow, and my country's crude oil exploitation shows a trend of high sulfur content. At the same time, the dependence on crude oil imports has reached about 60%. It has the characteristics of foul smell, high toxicity and strong corrosiveness, and its existence in crude oil has brought serious safety problems to oil field production and oil and gas gathering and transportation. Therefore, it is necessary to desulfurize crude oil and natural gas to meet relevant standards. [0003] According to the different physical characteristics of the desulfurization agent, it can be divided into dry method, wet method, biological desulfurization method, etc.; dry desulfu...
