Proposed device contains liquid nitrogen evaporator with heater, compressor for nitrogen gas, heater of gaseous nitrogen by ambient air heat, turbine or stage of turbines operating on heated nitrogen, pipelines connecting design members. Pipeline from evaporator to compressor is made heat-insulated, and pipeline from compressor to turbine or stage of turbines, non-heat insulated. Heater for heating compressed nitrogen by heat of ambient air is made in form of two parallel alternately connected heaters with coils for condensing water in form of dew or ice periodically melted by electric heaters. For additional cooling of gaseous nitrogen getting out of turning or turbine stage cooler is provided made in form of coil dipped in liquid nitrogen. Method of producing electric energy and fresh water conclude consists in the following operations: evaporated nitrogen at temperature of 85-100 K is first subjected to 50-20 fold compression, and its temperature is raised to temperature lower than ambient temperature and then temperature of gaseous nitrogen is raised by heat of ambient air in heaters at constant pressure to temperature of ambient medium air. Condensation of steam from air in form of dew or ice is provided, ice being periodically melted by electric heaters. Then gaseous nitrogen is directed to turbine or stage of turbines to provide rotation of electric generator and generation of energy, and cooled gas is directed into coil arranged in liquid nitrogen to reduce temperature of initial state at constant initial pressure.

Abstract: Изобретение относится к сахарной промышленности. Способ заключается в следующем. Кристаллы сахара заводят в количестве 8-9 шт. на 1 мм длины поверхности пробного стекла. Осуществляют их наращивание до достижения в утфеле 91-91,5% сухих веществ и отбирают утфель из вакуум-аппарата в количестве 35-40% от общей массы. После центрифугирования отобранной части утфеля кристаллы сахара промывают горячей водой с отделением оттека. Оставшийся в вакуум-аппарате утфель раскачивают сиропом до 88-89% сухих веществ и проводят повторное наращивание кристаллов путем подачи в вакуум-аппарат сиропа. Возврат оттека отобранной части утфеля в вакуум-аппарат осуществляют после окончания подачи сиропа. Уваривание оставшейся в вакуум-аппарате части утфеля до готовности проводят до 92-92,5% сухих веществ. Изобретение обеспечивает повышение выхода сахара-песка стандартного качества из утфеля первой кристаллизации при уменьшении длительности его уваривания.

Granted: 2003-12-20
Abstract: FIELD: inorganic chemistry, chemical technology. SUBSTANCE: invention relates to method for preparing phosphoric acid with low content of impurities used in production of phosphates with technical and food grading. Method involves liquid extraction with tributyl phosphate and the following separation of aqueous and organic phases and re- extraction of phosphoric acid from organic phase with water. Extraction and re-extraction are carried out in pulsation columns by mixing aqueous and organic phases to form emulsion at air effect at temperature of extraction 30-50 C and temperature of re-extraction 40-80 C. The total water flow feeding to re-extraction stage is divided for two parts in the ratio V1 : V2 = 1 : (3-9); the first part of water is mixed with extract and after separation of phases an aqueous phase polluted with impurities is mixed with wet-process phosphoric acid in the volume ratio = 1 : (6-15) followed by transfer to the extraction stage with tributyl phosphate to the start of process and extract is fed to mixing with the second part of water for preparing the purified phosphoric acid. Method provides reducing content of impurities of metals in the purified acid by 2-4-fold, i. e. to enhance quality of the purified acid. EFFECT: improved treatment method. 6 cl, 1 tbl, 2 ex
