Abstract: The invention relates to an arrangement with a mounting support for a motor vehicle front end, wherein the arrangement has two supporting elements for supporting a panel/fascia element, wherein the supporting elements are each arranged on one side of the motor vehicle relative to the vehicle center in the transverse direction of the vehicle, wherein the supporting elements are fixed to the mounting support and each extend over a portion of the mounting support in the vehicle transverse direction, wherein the supporting elements project forward relative the mounting support in the vehicle longitudinal direction, wherein a panel/fascia element, which is an external skin element of the front of the motor vehicle and extends predominantly in the vehicle transverse direction, can be supported on at least one of the supporting elements.

Abstract: The process of concentrating a dilute sulfuric acid in a three-stage vacuum evaporation plant includes feeding an entry dilute sulfuric acid to a first evaporation stage of a vacuum evaporation plant to form an overhead vapor (6), withdrawing a finally concentrated sulfuric acid from the third evaporation stage (3), using steam or the overhead vapor (6) of the first evaporation stage as a heating fluid in the three-stage vacuum evaporation plant, maintaining the entry dilute sulfuric acid under a pressure of 0.4 to 0.7 bar and at a temperature of 80.degree. to 120.degree. C. in the first evaporation stage (1), maintaining the partially concentrated sulfuric acid under a pressure of 0.02 to 0.06 bar and at a temperature of 50.degree. to 90.degree. C. in the second evaporation stage (2), maintaining the further concentrated sulfuric acid under a pressure of 0.02 to 0.06 bar and at a temperature of 80.degree. to 120.degree. C.

Abstract: A process for decreasing the tendency to form deposits in plants for evaporating spent sulfite liquors used to produce woodpulp. In the process, the liquors are treated with polyacrylic acids having a low molecular weight. In order to prevent virtually any deposition and to increase the evaporation rate, an aqueous solution of polyacrylic acid having a low molecular weight is added to the spent sulfite liquor in an entrance stage of the multiple-effect sulfite liquor in an entrance stage of the multiple-effect evaporating system and an aqueous solution of a copolymer of sulfonated styrene and maleic anhydride or an aqueous solution of a polyacrylic acid having a low molecular weight is added to the spent sulfite liquor in at least one succeeding stage of the multiple-effect evaporating system.
