Title: Recovery of regenerating gas for adsorber - used to remove water from natural and refinery gases
Inventor: SCHMIDT HANS DR ING
IPC: B01D53/04
Filed: 1991-03-12
Abstract: A process is claimed for the recovery of regenerating gas for an adsorber as part of a prod. stream contg. light hydrocarbons under crude gas pressure. The prod. stream comes from an sepn. plant for moisture, under-pressure hydrocarbon-contg. crude gas streams, which are dried before sepn. by adsorbers. the recovery is possible by keeping a low water content of the product gas stream. The novelty is that the regenerating gas used to regenerate the adsorber charged with water is sealed before regeneration to crude gas pressure, and after regeneration, is either mixed with the prod. gas stream, or, on exceeding the max. permitted water content of the product gas stream, is mixed with moist crude gas before adsorption. Pref. a gas contg. light hydrocarbons, precipitating in the sepn. plant, is used as the regenerating gas. USE/ADVANTAGE - The process is used to regenerate adsorbers used to remove water from natural and refinery gases. Operational costs and energy used are reduce

Title: Drawing unit monitor esp. useful for mfg. synthetic yarns - has sensor for at least one electromotor for drafting force to be calculated from slip and or pole wheel angle
Inventor: KIEHL WERNER DR
IPC: G01L3/00
Filed: 1991-04-25
Abstract: To monitor the drafting force exerted by the drawing unit for spinners, a sensor (3) registers the rotation of at least one electro-motor (1) where the sliver is drawn between two separate rotation units with their own motors. The difference in the frequency and/or phase between the sensor signal (120) and the nominal frequency signal (110) at the associated frequency converter (2) is established to give the slip and/or the pole wheel angle of the electro-motor to provide the drawing force exerted. Pref. the pole wheel angle or the slip or the calculated drafting force is used as a control value for the electro-motor (1) supplied by a frequency converter, and the drawing action is stopped if the drafting force lies outside preset tolerances, and a signal is generated if the measurements are above or below the nominal value. For test purposes, the drawing unit is operated without material and a signal is generated if the measured parameters are exceeded and, if within limits, the theoretical drafting force is used as a reference value when working with sliver material. The running time of the drafting force, while the spinner is operating, is set to monitor the drawing operation. ADVANTAGE - Pref. the method gives a simple and accurate measurement of the drafting forces at the drawing unit.
