20100219128 | DEHYDRATION SYSTEM AND DEHYDRATION METHOD - A dehydration system has improved membrane performance. The dehydration system includes a dehydrating apparatus 1 comprising, in a dehydrating apparatus body, a water separation membrane module in which a water separation membrane having at least one flow path extending in the up and down direction to cause a liquid | 09-02-2010 |
20100258197 | METHOD FOR TRANSPORTING FLUID - There is provided a method for transporting a fluid, in which even if the fluid is transported for a long period of time, dehydration after transportation is not needed, and the transported fluid can be used immediately after transportation. Specifically, there is provided a method for transporting a fluid, comprising steps of: dehydrating some of the transportation fluid during transportation by using a dehydration system comprising a separation membrane through which water permeates, and returning the dehydrated fluid to the transportation fluid so as to keep water content in the transportation fluid in a fixed range. In one embodiment, the transportation fluid is a liquid, and the dehydration system comprises a heater for heating the liquid to a temperature in a range in which the liquid does not boil, and a membrane separation apparatus for dehydrating the heated liquid, wherein the membrane separation apparatus is a PV method apparatus comprising a primary side chamber extending in an up and down direction to introduce the liquid from a lower portion thereof and discharge it from an upper portion thereof, a separation membrane in contact with the primary side chamber to allow water in the liquid to permeate through as a gas, and a secondary side chamber being located on the opposite side to the primary side chamber with the separation membrane held therebetween and being under a pressure lower than that in the primary side chamber. | 10-14-2010 |
20100320148 | DEHYDRATING SYSTEM AND DEHYDRATING METHOD - A dehydrating system using multiple water separation membranes aims to prevent damage to the water separation membrane units and also to take appropriate measures against decrease in water permeation rate of the water separation membranes. Provided is a dehydrating system ( | 12-23-2010 |
20140051895 | DEHYDRATION METHOD - The present invention includes a dehydration method comprising the steps of providing a distilled process-target fluid to a water separation membrane device via a heat exchanger; separating the process-target fluid into a dehydrated product and water by using the water separation membrane device; detecting a temperature of any one of the water separation membrane device and the process-target fluid supplied to the water separation membrane device by using a temperature monitoring device; and controlling the temperature of the process-target fluid so that the temperature of the distilled process-target fluid being maintained at a temperature higher than the condensation temperature of the distillate by 5 to 10° C. by using a temperature adjustment device provided in the water separation membrane device. | 02-20-2014 |
