  • Patent number: 7026363
    Abstract: The present invention relates to the use of alkoxylated polyglycerols preparable by polycondensation of glycerol and subsequent alkoxylation for demulsifying water-oil emulsions, in particular in the production of crude oil from crude oil/water emulsions. The invention provides for the use of alkoxylated polyglycerols with a molecular weight of from 250 to 100,000 units which comprise 2 to 100 glycerol units whose free OH groups are alkoxylated with C2–C4-alkylene oxide groups or a mixture of such alkylene oxide groups so that the alkoxylated polyglycerol has a degree of alkoxylation of from 1 to 100 alkylene oxide units per free OH group. The alkoxylated polyglycerols of the present invention are employed for demulsifying oil/water emulsions in amounts of from 0.0001 to 5% by weight, based on the oil content of the emulsion to be demulsified.

  • Patent number: 6983612
    Abstract: The invention relates to a method for producing a phenothiazine granulate with a narrow particle size distribution. At least 98% pure phenothiazine in liquid form is pressed through a device provided with boreholes and a frequency is applied to said liquid phenothiazine. The liquid phenothiazine discharged through the boreholes enters a cooling medium having a temperature of between ?196 and +120° C. The drops of liquid phenothiazine thus produced are brought to a temperature below melting point and are optionally solidified in another post-cooling area. Optionally, fine-grain particles or coarse-grained particles thus formed can be subsequently removed by appropriate methods. The bulk density of the obtained phenothiazine granulates ranges more particularly from 720–780 kg/m3.
