  • Patent number: 4430161
    Abstract: In a coking process, coal to be coked is preheated in a cascaded whirling bed drier into which the coal is charged from above and exposed to an indirect heat transfer while whirling in a coal-steam mixture. Hot gas applied to the heating pipes in respective cascades of the drier is branched off from the total amount of hot gases discharged from a dry cooler in which hot coke from the coke oven is cooled by recirculating cooler gas constituted by a partial gas stream discharged from the cascades of the drier and reunited with the other partial stream subject to a heat exchange for generating steam. Steam from the whirling beds is discharged from the cascaded drier, separated from the entrained dust particles, and then the excessive steam is drained in a branch conduit and the remaining steam is compressed and reintroduced into the lowermost whirling bed in the drier.

  • Patent number: 4418217
    Abstract: A process for the production of a mixed formal of polyglycol ethers having formulae selected from the group consisting of ##STR1## wherein R.sup.1 is a straight or branched chain alkyl having from 1 to 18 carbon atoms, and R.sup.2 is selected from the group consisting of hydrogen and straight or branched chain alkyl having from 1 to 17 carbon atoms, where the sum of the carbon atoms in R.sup.1 plus R.sup.2 is from 6 to 18, R.sup.3 is a member selected from the group consisting of monoalkylphenyl having from 14 to 26 carbon atoms, dialkylphenyl having from 14 to 26 carbon atoms, trialkylphenyl having from 14 to 26 carbon atoms, a straight or branched chain alkyl having from 8 to 22 carbon atoms, a straight or branched chain alkenyl having from 8 to 22 carbon atoms, and a radical having the formula ##STR2## wherein R.sup.1 and R.sup.2 have the above assigned values, and R.sup.

  • Patent number: 4370203
    Abstract: A cooling device for dry cooling of coke by a counterflow of gaseous cooling medium has a prechamber, a housing including upper and lower parts, a conduit for discharging a gaseous cooling medium, wherein the prechamber form with the housing an annular space of an increased cross-section in the region of the discharge conduit, the prechamber is connected with the housing by a plurality of mounting members distributed over the periphery of the prechamber, and two sliding joints are provided of which one sliding joint slidingly connects the upper wall with the lower wall, and the other sliding joint slidingly connects the prechamber with the upper wall.

  • Patent number: 4364777
    Abstract: An alkaline washing composition comprised of strongly alkaline reacting inorganic salts, optionally wetting agents and a defoaming effective amount of at least one mixed formal of an alkylpolyglycol ether having the formula:R.sub.1 --O--(CH.sub.2 CH.sub.2 O).sub.m --CH.sub.2 --(OCH.sub.2 CH.sub.2).sub.n --O--R.sub.2wherein R.sub.1 is a straight or branched chain alkyl or alkenyl with from 8 to 22 carbon atoms, R.sub.2 is a straight or branched chain alkyl with from 1 to 5 carbon atoms, m is a number from 2 to 30 and n is a number from 1 to 3; as well as the improvement in the process of washing rigid solid articles comprising contacting the soiled rigid solid articles with a strongly alkaline washing solution containing a defoaming effective amount of a defoaming agent, rinsing said rigid solid articles and recovering cleaned rigid solid articles, the improvement consisting of using said mixed formal as said defoaming agent.
