Modified Boyle method

The Boyle method (see A5.13) can be used to estimate the diameter required for a dump system. It will usually be safe to assume liquid-only flow if dumping occurs well before the maximum rate (the original Boyle method). Alternatively, the conservative assumption that a homogeneous two-phase mixture (rather than liquid alone) enters the dump system from the reactor could be made (the modified Boyle method). 

In the original Boyle method1181, it was recommended that the relief system capacity be calculated on the basis of non-flashing liquid flow, and a safety factor of 3 applied to the result. The modified Boyle method1161 uses a relief system capacity calculated on the basis of two-phase flow. The modified Boyle method is therefore ... 

ETAAS is primarily used for samples that have been pre-concentrated and separated from major ions (see Section 12.1.2). In the literature, various techniques have been described by Boyle and Edmond (1977) Smith and Windom (1980) Sturgeon et al. (1981), Bruland et al. (1985) Hartmann et al. (1989) or Van Geen and Boyle (1990). The method ontlined here is a procedure modified from Danielsson et al. (1978) and Bruland et al. (1979). It pro-...
