20130167568 | APPARATUS AND METHOD FOR MEASURING CONCENTRATION OF LIQUID-STATE REFRIGERANT OF NONAZEOTROPE REFRIGERANT MIXTURE, AND ABSORPTION TYPE, 1-STAGE COMPRESSING-ABSORBING TYPE AND 2-STAGE COMPRESSING-ABSORBING TYPE HEAT PUMP INCLUDING THE APPARATUS - An apparatus and method for measuring concentration of a liquid-state refrigerant of a nonazeotrope refrigerant mixture. A container is disposed in such a way that a liquid-state refrigerant mixture of the nonazeotrope refrigerant mixture in a saturated state is temporarily stored with set quality. By measuring temperature and pressure of the liquid-state refrigerant mixture, concentration of the liquid-state refrigerant can be calculated from a database regarding a relationship between a saturation vapor pressure, temperature, quality, and concentration of the previously-stored nonazeotrope refrigerant mixture in the saturated state. Thus, a configuration for measuring the concentration of the liquid-state refrigerant-absorbent mixture includes a container, a temperature sensor and a pressure sensor and thus is very simple and the cost for the configuration can be reduced. In addition, the container can be easily mounted on existing equipment without disturbance of a flow. | 07-04-2013 |
20130167581 | DEHUMIDIFIER FOR A COMPRESSOR, 1-STAGE COMPRESSING-ABSORBING TYPE HEAT PUMP SYSTEM AND 2-STAGE COMPRESSING-ABSORBING TYPE HEAT PUMP SYSTEM - A dehumidifier for a compressor, including: a plurality of dehumidifying members that absorb moisture; and a flow passage controlling valve module that enables a low-temperature vapor refrigerant to alternately flow into the plurality of dehumidifying members and enables the low-temperature refrigerant to flow into a compressor in a state where moisture contained in the low-temperature refrigerant is absorbed and is removed, enables a high-temperature vapor refrigerant ejected from the compressor to alternately flow into the dehumidifying members and regenerates the dehumidifying members. Thus, since a liquid-state absorbent contained in a refrigerant flowing into the compressor is removed by the dehumidifier, damage caused by liquid compression and corrosion of the compressor can be reduced. In addition, the structure of the dehumidifier is simple, and an additional external heating source is not required. | 07-04-2013 |

20130206575 | PRODUCTION OF HIGH PURITY BUTENE-1 FROM C4 OLEFINS/PARAFFINS MIXED GAS - A hybrid process comprising an adsorption process and a distillation process for the separation of butene-1 from a C4 hydrocarbon mixture gas including butene-1, trans-2-butene, cis-2-butene, normal butane, isobutane, etc. is provided. The hybrid process comprises introducing a gaseous C4 mixture into the adsorption tower loaded with adsorbents which adsorb olefins selectively to discharge C4 paraffins to the outlet of the tower, desorbing C4 olefins selectively adsorbed in the adsortion tower to produce high purity C4 olefins mixture gas in which isobutane and normal butane was removed, and separating the high C4 olefins mixture gas (a mixture of butene-1, trans-2-butene, cis-2-butene, and a trace amount of C4 paraffins) via distinction to obtain high purity butene-1 including a trace amount of isobutane in the top of the distillation tower and obtain a mixture gas including trans-2-butene, cis-2-butene and a trace amount of normal butane in the bottom of the tower. | 08-15-2013 |
20130207033 | Method for Preparing Carbon Dioxide Absorbent Based on Natural Biomass and Carbon Dioxide Absorbent Based on Natural Biomass Prepared by the Same - A method for preparing a carbon dioxide absorbent based on natural biomass, and a carbon dioxide absorbent based on natural biomass that is prepared by the method. The method utilizes alkali metal or alkaline earth metal components, such as Ca, Ma and K, inherent to a natural plant biomass material. The method can provide a carbon dioxide absorbent with improved performance in an environmentally friendly manner at greatly reduced cost. | 08-15-2013 |
20130213793 | SEPARATION OF OLEFINS FROM OLEFINS/PARAFFINS MIXED GAS - A method and apparatus for the separation of C4 olefins (butene-1, trans-2-butene, cis-2-butene, etc.) and C4 paraffins (normal butane, isobutane, etc) from a C4 hydrocarbon mixed gas including butene-1, trans-2-butene, cis-2-butene, normal butane, isobutane, etc. is provided. The apparatus includes several adsorption towers loaded with an adsorbent which selectively adsorb olefins and two distillation towers for the separation of the mixture gases of olefins/desorbents and paraffins/desorbents respectively. The basic operating process of the adsorption tower comprises an adsorption step of selectively adsorbing C4 olefin from the feeding mixture, a C4 olefin rinse step of removing a small amount of C4 paraffins adsorbed together with C4 olefins, and a desorption step of desorbing C4 olefins by using a desorbent, and further comprises pressure equalization step, concurrent depressurization step, and accumulation pressure step to increase the yield and concentration of olefins depending on the operation pressure of the adsorption tower. | 08-22-2013 |
