Abstract: PURPOSE:An electrical desalting auxiliary for crude petroleum exhibiting good water recovery and desalting when added in a small amt., which comprises a specified polyoxyalkylenealkylphenol-formaldehyde condensate contg. a polyoxyethylene chain in the molecule. CONSTITUTION:An electrical desalting auxiliary comprising a polyoxyalkylenealkylphenol-formaldehyde condensate of average MW of 1,400-2,800 calculated excluding the polyoxyalkylene chain, contg. 45-70wt% polyoxyethylene chain in the molecule and having an 8-12C alkyl group. The polyoxyalkylenealkylphenol-formaldehyde condensate to be used has formula I (wherein R is 8-12C alkyl; R1 is 3-5C alkylene; each of m1, m2 and m3 >=0; each of x, n1, n2 and n3 >=1). It is important that the alkylphenol-formaldehyde condensate which is removed from the polyoxyalkylene chain in the chemical structure of the formula I, namely the portion of formula II has an MW of 1,400-2,800, otherwise the performance remarkably deteriorates.

Abstract: PURPOSE:To obtain a highly efficient oil-water separating agent having a specified HLB value, by adding ethylene oxide to a mixture of a fatty acid triglyceride and polyhydric alcohol. CONSTITUTION:0.1-5mol of a plyhydric alcohol, e.g. glycerol, butanetriol, pentanetriol, hexanetriol, sorbitol, mannitol, xylitol or dulcitol, is used for 1mol of a fatty acid triglyceride, while 2-100mol of ethylene oxide is used for 1mol of the sum of the fatty acid triglyceride and the polyhydric alcohol. The obtained oil-water separating agent is added, as such or diluted with an organic solvent, to a crude oil emulsion at a rate of 0.001-0.05wt% in general. The oil- water separating agent is effective for any kind of crude oil emulsion and facilitate oil-water separation remarkably.
