Title: Process for separating off SO2 and NOx and return of residues to the coal waiting for combustion
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1986-10-18
Abstract: The invention relates to a process for the simultaneous scrubbing of SO2 and NOx and simultaneous establishment of the necessary stoichiometric ratio of SO2 to NOx and destruction of excess NH3 in flue gas. In order to arrange the ratio of SO2 to NOx advantageously for the simultaneous technique and, at the same time, to remove NH3 from the flue gas and from the scrubbing circulation and thus to obtain a waste water-free wet flue gas desulphurisation process, according to the invention it is proposed that the scrubbing liquid volume is fed to a delay vessel for improving the reduction of Fe(III) to Fe(II), this vessel at the same time being designed as a sink-separator for CaSO3/CaSO4 and a predetermined, desired mixture, comprising CaSO3/CaSO4 and scrubbing solution being added under control to the firing chamber, if necessary also together with the fuel, that is to say for establishing a required SO2/NOx ratio with simultaneous destruction of NH3 and reduction of NOx.

Patent DE-3831855-A1 (DE)
Inventor: DOBO MIKLOS DIPL CHEM DR
IPC: B65H75/24
Filed: 1988-09-20
Abstract: When metal strips are wound and unwound, use is made of expanding winding spindles (1) with a cover (4) to prevent the hard winding spindle sections (6) from damaging fragile metal strips (3). Since the maximum yield strength of the elastomeric spindle cover is often exceeded as the winding spindles (1) expand, resulting in permanent deformation, the cover (4) may remain expanded and become undesirably detached with the coil (3) from the winding spindle (1). To prevent the winding spindle cover (4) from being stressed beyond its yield strength, a slit (5) is made in it, running approximately spirally from one end of the winding spindle cover (4) to the other.
