15 percent of the numerical value rounded to two significant digits for example if the specification describes a specific temperature of 62 u00b0 f such a description provides literal support for a broad numerical range of 25 u00b0 f to 99 u00b0 f 62 u00b0 f u2212 37 u00b0 f an intermediate numerical range of 43 u00b0 f to 81 u00b0 f 62 u00b0 f u2212 19 u00b0 f and a narrow numerical range of 53 u00b0 f to 71 u00b0 f 62 u00b0 f u2212 9 u00b0 f these broad intermediate and narrow numerical ranges should be applied not only to the specific values but should also be applied to differences between these specific values thus if the specification describes a first pressure of 110 psia and a second pressure of 48 psia a difference of 62 psi the broad intermediate and narrow ranges for the pressure difference between these two streams would be 25 to 99 psi 43 to 81 psi and 53 to 71 psi respectively one embodiment of the present invention is illustrated in fig1 and 2 the present invention provides a process for recovering a portion of oxidation solvent a portion of oxidation catalyst and removing a portion of.
