Abstract

A desalting chemical composition comprising 59 to 90 wt% of a solvent, 0 to 15 wt% of a wetting agent, and 10 to 50% of a mixture consisted of three types of polymeric nonionic surfactant; in which the three types of polymeric nonionic surfactant are: (1) 5%~30% of ethoxylated alkylphenol-formaldehyde resin of the formula (formula) in which n is 6 to 16, m is 1 to 20, p is 3 to 30, and the HLB of the surfactant is 4 to 16; (2) 5%~15% of polyalkoxylated polyol of the formula (formula) in which m is 6 to 30, n is 5 to 40, p is 3 to 6, in which the polyol is selected from at least one of the following: glycerin, trimethylol propane, erythritol, pentaerythritol, xylitol, and mannitol, and the HLB of the surfactant is 3 to 15; (3) 5%~15% of pluronic polyoxypropylene polyoxyethylene ether of the formula (formula) in which m is 15 to 150, and n is 5 to 30, and the HLB of the surfactant is 2 to 12.
