                    As shown in Figure 14 below, the waste H 2 SO 4  will be
                shipped by tank trucks from F15A or F15B, and transferred it to
                waste H 2 SO 4  storage tank area. Then waste H 2 SO 4  is pumped
                to Process area for purification. The final H 2 SO 4  product will
                be loaded to tank truck in product filling area and sent back to
                F15A or F15B for use.
