Patent ID: 8142662

Claim:
A dehydrating system that removes water from a fluid to be processed comprising an organic component and that provides a product fluid comprising the organic component, the dehydration system comprising: at least two water separation membrane units in use arranged parallel to a direction of flow of the fluid to be processed; at least one spare water separation membrane unit installed parallel to the direction of flow of the fluid to be processed with respect to the at least two water separation membrane units; a monitoring means to monitor a concentration of the organic component of the product fluid for product fluid taken out of each of the at least two water separation membrane units; a monitoring device configured to monitor a temperature of the product fluid for product fluid taken out of each of the at least two water separation membrane units; and a control unit configured to replace operation of one of the at least two water separation membrane units with operation of one of the at least one spare water separation membrane unit to maintain properties of the product fluid depending on the concentration of the organic component of the product fluid as monitored by the monitoring means and the temperature of the product fluid as monitored by the monitoring device.
