Japan, Sept. 16 -- RIPCORD ENERGY SOLUTIONS LLC has got intellectual property rights for 'REMOVAL OF HYDROGEN SULFIDE AND/OR MERCAPTAN FROM PETROLEUM OR PETROLEUM DERIVATIVE AND TREATMENT COMPOSITION FOR ACHIEVING REMOVAL.' Other related details are as follows:
Application Number: JP,2025-155223
Category (FI): C10G19/02,C10G27/06
Stage: PROBLEM TO BE SOLVED: To solve the problem that although, in a conventional method, it is shown that hydrogen sulfide in petroleum is reduced, a faster, more effective, more cost-efficient, and more environmentally friendly method is required for removing sulfur compounds including removing not only hydrogen sulfide but also mercaptans from crude oil and petroleum distillates.SOLUTION: An aqueous treatment composition for crude oil and/or petroleum distillates for removing sulfur compounds from crude oil and/or petroleum distillates, and a treatment method using the composition are disclosed. The composition comprises less than 0.5 mass% of a di- or tri-benzohydroxy compound, a strong base, less than 1 mass% of a divalent metal gluconate, and a balance of water, and has a pH of 9 or greater. The treatment method comprises adding the treatment composition to crude oil or petroleum distillates to form a mixture having 0.001-0.02 mass% of a di- or tri-benzohydroxy compound in petroleum and 0.001-0.03 mass% of a divalent metal gluconate in the petroleum, and mixing the components together.SELECTED DRAWING: Figure 1 (Grant)
