  • Publication number: 20200299222
    Abstract: The invention relates to a method for hydrogenation of a phthalate compound. According to the method, the generation of by-products may be inhibited during hydrogenation, and thus, catalytic activity may be improved and catalyst life may be prolonged, thereby increasing the efficiency and economical feasibility of commercial processes. And, since the hydrogenation product prepared by the method has high purity and low acid value, it has excellent quality as a plasticizer, and thus, can be used for various products.

  • Publication number: 20200031199
    Abstract: A PTC heater includes PTC heater parts in which heater rods and radiation fins are alternately arranged. A frame is formed along a circumference to support the PTC heater parts. IGBT elements are installed on the frame and selectively apply a battery current to each of the heater rods to adjust the heat generation amount of the heater rods. A control module is installed on the frame and controls the IGBT elements to adjust the heat generation amount of the heater rods according to a target temperature value. A heat sink is installed on the frame, is connected with the IGBT elements for heat-exchange, is formed to pass the PTC heater parts in the horizontal direction and radiate heat of the IGBT elements through the flowing air inside the air conditioning case.

  • Publication number: 20160121261
    Abstract: A carbon dioxide separation device has an absorption tower for receiving exhaust gas and configured to cause carbon dioxide, included in the exhaust gas, and an absorbent to react with each other. The separation device has a pressure reduction and phase separation unit to depressurize the CO2-rich-solution, and cause heat exchange between a lean solution and the CO2-rich-solution and separate a phase of the CO2-rich-solution into gas and liquid. In the separation device lean solution flows into the pressure reduction and phase separation unit, and the CO2-rich-solution undergoes a phase separation into gas and liquid due to heat of the lean solution, and then, flows into the stripping tower.
