    Abstract: In one aspect, the invention is directed to a method for determining the concentration of anionic polymers or oligomers in industrial water comprising combining a buffer solution and a cationic dye solution, measuring absorbance of the buffer-dye admixture at selected wavelength(s) and determining the polymer or oligomer concentration from the previously determined absorbance values. In alternate embodiments of the invention, the buffer solution may be a multifunctional buffer solution and may be comprised of multiple buffers, masking agents. and/or stabilizing agents and combinations thereof. Other embodiments provide that multiple dyes may be employed.

    Abstract: In addition to ash and coke, the gasification residue contains alkaline earth metal sulfide and alkaline earth metal oxide because desulfuring agents have been supplied to the gasifier. At temperatures from 5.degree. to 80.degree. C. the gasification residue is mixed with an acid-containing aqueous solution so that a gas which is rich in H.sub.2 S is produced. Ash, coke, and alkaline earth metal salt are supplied to a flotation zone, in which coke is separated. A solid residue which contains ash and alkaline earth metal salt is withdrawn from the flotation zone. Carbonic acid or dilute sulfuric acid is preferably used as an acid.

    Abstract: A method for operating a battery of coke ovens capable of accomplishing an increase in production and a decrease in the quantity of heat required for carbonization. The battery of cove ovens include a plurality of carbonization chambers to which a series of working numbers indicating the order of unit oven workings are assigned. An operation step is repeatedly practiced which includes a working step of carrying out the unit oven workings in the order of working numbers with respect to the carbonization chambers without providing a working interrupting time between the unit oven workings and an interruption step of interrupting the unit oven working until the the carbonization chamber of the coke oven which has been first subject to the unit oven working reaches a time at which discharge from the carbonization chamber is made possible.
