IPC: C01B25/163
Filed: 1990-08-16
Abstract: In a continuous process for the preparation of phosphorous acid with simultaneous production of hydrochloric acid, a reaction zone is provided which is in open communication with a first scrubbing zone. A portion of the reaction product is recycled from the bottom of the reaction zone into the top of the scrubbing zone and phosphorous acid is removed from the circulation. Hydrogen chloride gas escaping from the top of the first scrubbing zone is brought into contact, in a cooled, second scrubbing zone, with an overstoichiometric amount of water. Hydrochloric acid is obtained which is passed as starting material into the reaction zone or into the top of the first scrubbing zone. The external cooling of the second scrubbing zone is controlled such that the temperature in the reaction zone is kept constant at a desired value between 90 DEG  and 130 DEG  C. without adding any external cooling or heating energy. Pure hydrochloric acid is recovered in an absorption zone.

Inventor: SPILGER GERHARD
IPC: H02H7/122
Filed: 1991-10-18
Abstract: Proposed is a method of avoiding overcurrents in a welding converter which generates, using power semiconductors, two-phase pulse-modulated a.c. power from a rectified mains a.c. power supply, the two-phase power being fed to the primary coil of a welding transformer. The method comprises the following steps: the power in at least one phase of the primary-coil circuit is measured by means of a sensor (20), the time differential of each measured signal is determined by differentiation with respect to time, and the time differential of the measured signal is compared with a predetermined maximum value.
