Patent ES-2217079-T3 (ES)
Inventor: BIRBAUMER HUGO
IPC: B66B1/04
Filed: 2001-12-06
Granted: 2004-11-01
Abstract: The hydraulic elevator system, with a passenger cabin (1), has a pump (13) to move hydraulic oil between the pressure store (17) and the hydraulic drive (2) in both directions. Electrically controlled ON/OFF valves (12,15) are on each side of the pump. A pressure switch (22) and a loading pressure sensor (31) act on a system (13,14,24,25) to prevent a rapid change in pressure before the cabin starts to move. When the cabin is at rest, the pressures between the pump and the flanking valve are varied so that any pressure difference is canceled, before the valves are opened.

Abstract: The present invention provides a novel process of recovering unreacted ammonia from a reactor effluent. This novel process includes at least the following steps: (1) quenching a reactor effluent containing ammonia with a first aqueous ammonium phosphate quench solution, wherein the pH of the solution is less than about 3.5, thereby absorbing ammonia to form a second aqueous ammonium phosphate solution richer in ammonium (NH4<+>) ions than the first solution but substantially free of dissolved CO2, (2) heating the second solution to an elevated temperature to reduce the amount of ammonium ions present to substantially the same level present in the first solution and thereby generate a vaporous stream containing ammonia, (3) recycling said vaporous stream containing ammonia to a reaction zone in a manner that minimizes the contamination of the reaction zone.

Abstract: A fusion heater (7) is placed in direct contact with the bottom of an internal vessel to heat it without using oil. The solvent is distilled at atmospheric pressure or under vacuum and is condensed for recovery by a plate exchanger cooled with water. A chamber for static cooling with ambient air is placed upstream of the exchanger to reduce the temperature drop across the exchanger A used solvent regenerator has an internal vessel (2A) which contains the solvent and an external vessel (2B) enclosing the internal vessel and containing insulation (4). The regenerator also includes a mixer and a means for injecting air or steam so that near the end of the distillation cycle the residues are mixed and/or air or steam is injected. There is a scraper at the bottom for solid residues to avoid fouling of the base and allowing powdered residues to form. The regenerator also has a chamber before the plate exchanger which allows a static cooling with ambient air and avoids too great a temperature drop which could deform the exchanger plates.
