Abstract
A treatment composition for being added to petroleum based liquids for reducing total sulfur content in the petroleum based liquids, comprising: sodium sulfide and at least one hydroxide compound. A dosage of the treatment composition may be added to liquids containing sulfur, including crude oil and distillates of crude oil and then allowed to react with such liquids over a period of time, e.g., hours or days. By such reaction total sulfur content of the liquids may be reduced by more than 50%.
Claims8
A treatment composition for being added to petroleum based liquids for reducing total sulfur content in the petroleum based liquids, comprising:
- sodium sulfide, water and at least one hydroxide compound.
A treatment process for reducing total sulfur content in a petroleum based liquid, comprising steps of:
- dissolving sodium sulfide and at least one hydroxide compound in water to form an aqueous solution;
- adding the aqueous solution to the petroleum based liquid, wherein a dosage amount of sodium sulfide is 0.01 to 5.0 g per liter of the petroleum based liquid and a total dosage amount of the at least one hydroxide compound is in a range of 0.01 to 5.0 g per liter of the petroleum based liquid;
- of dispersing the aqueous solution into the petroleum based liquid;
- and allowing the sodium sulfide and the at least one hydroxide compound to react with the petroleum based liquid.
