Abstract: A device for drying medium flow (8), in particular an air flow, includes a device housing (2), in which at least first and second drying agents (4, 6) are received. The first and second drying agents have a high moisture absorption capacity in the case of low and high moisture values of the medium flow (8), respectively. The amount of the respective drying agent (4, 6) can be selectively set depending on the actual moisture present in the medium flow (8).

Abstract: The invention relates to a device for drying a medium flow (8), in particular an air flow, comprising a device housing (2), in which at least one first and at least one further drying agent (4, 6) are received, having high moisture absorption capacity in the case of low or high moisture values of the medium flow (8), and wherein the amount of the respective drying agent (4, 6) can be selectively set depending on the actual moisture present in the medium flow (8).

Abstract: A process for inhibiting a liquid hydrocarbon from foaming involving: (a) providing a liquid hydrocarbon; (b) providing a defoamer additive containing: (i) an ester corresponding to formula (I) R1—COO—R2??(I) wherein R1 and R2 are, independent of each other, saturated or unsaturated, linear or branched alkyl radicals having from about 6 to 16 carbon atoms, as a defoamer; and (ii) optionally, a co-defoamer selected from the group consisting of a non-alkoxylated ester of a polyol having from about 2 to 6 carbon atoms, and from about 2 to 4 OH groups, a saturated or unsaturated, linear or branched fatty acid having from about 8 to 24 carbon atoms, and mixtures thereof; and (c) adding a foam-inhibiting effective amount of (b) to (a).

Abstract: The invention relates to a method for defoaming liquid hydrocarbons, whereby these vinyl alkylether polymerizates of general formula (I), in which R represents a saturated or unsaturated, straight or branched alkyl radical with 2 to 18 C atoms, and n represents a number >1, are added in quantities ranging from 1 to 2000 ppm.
