[0196] Determination of Saturation Capacity and Refining Capacity
[0197] Freundlich isotherm constant, K f and 1 / n, are fitting constants indicating the degree of interaction between the adsorbate and the adsorbent. In this example, the filter is designed to remove diesel hydrocarbons from water. In a typical experiment, the adsorption properties of various materials were determined as follows. Different masses (50 mg-500 mg) of each material were challenged with 20 mL of B5 diesel fuel in water dispersion (typically 1000-2500 ppm hydrocarbon content). The samples were equilibrated overnight and the equilibrium hydrocarbon concentration of each sample was determined using GC-MS (gas chromatography-mass spectrometry) relative to n-hexadecane (C16) standards. The data are processed using a linearized form of the empirical Freundlich isotherm expression:

example A
[0213] The adsorption properties of high capacity carbon (Silcarbon K48) and refined carbon (NoritGCN 1240) were determined by running isotherm experiments as described previously. The isotherm parameters for the 2500 ppm B5 in water diesel fuel dispersion challenge are presented in Table 1. The target cleanliness for this example is 2 ppm.
[0214] As observed, the Silcarbon K48 carbon has a higher saturation capacity while the Norit GCN 1240 carbon has a higher loading capacity when an outlet hydrocarbon concentration of 2 ppm is targeted. Therefore, a hydrocarbon-in-water purification system comprising a Silcarbon K48 high capacity section followed by a Norit GCN 1240 finishing section will have a longer life than an equivalent mass system comprising only Norit GCN 1240 finishing carbon.
[0215] By splitting the absorbent bed into two sections, where the first section uses high capacity material and the second section uses refined material, we can increase the life of the...
example B
[0218]A filter containing 357g of Chemviron Carbsorb 28FB will purify 112L of water before breaking through the 2ppm target concentration. By splitting the filter into two equal mass segments of Norit ROW 0.8 Supra (high capacity carbon) and Carbsorb 28FB (refined carbon), the life of the filter is increased to 148L of water. Further refining the system found that the best life in the multi-batch model was 90% by weight high capacity carbon and 10% by weight refined carbon. These ratios may vary for different specific adsorbents. At this ratio, the filter will clean 167L before breaking 2ppm. This is a 49% increase in hydrocarbon absorbent filter life.
