ABSTRACT:
An elongated tube having a tube wall permeable to a gas and impermeable to a liquid is used to transfer a gas from one side of the tube wall to the other. For some purposes, such as fertilization, anhydrous ammonia is introduced into such a tube with the tube being disposed in soil at or below root level of the plants. The amount of ammonia dispensed through the tube wall is a function of the pressure of the ammonia. The ammonia may also be carried in the tube using water in which it is dissolved forming ammonium hydroxide. The same type of tube when disposed above a fermenting aqueous sugar in a fermentation vat will collect carbon dioxide resulting in enhanced fermentation. The tube may be connected to an exhaust fan. The same type of tube may be disposed in a sanitary land fill with water circulating through the tube to collect water gas formed by the decomposition of the waste material.
