Forced draught burners -- Part 2: Oil burners
5.1 Residual fuel oils can contain H2S in the liquid phase, and this can result in hazardous vapor phase levels of H2S in storage tank headspaces. The vapor phase levels can vary significantly according to the headspace volume, fuel temperature, and agitation. Measurement of H2S levels in the liquid phase provides a useful indication of the residual fuel oil’s propensity to form high vapor phase levels, and lower levels in the residual fuel oil will directly reduce risk of H2S exposure. It is critical, however, that anyone involved in handling fuel oil, such as vessel owners and operators, continue to maintain appropriate safety practices designed to protect the crew, tank farm operators and others who can be exposed to H2S. 5.1.1 The measurement of H2S in the liquid phase is appropriate for product quality control, while the measurement of H2S in the vapor phase is appropriate for health and safety purposes. 5.2 This test method was developed so refiners, fuel terminal operators and independent testing laboratory personnel can analytically measure the amount of H2S in the liquid phase of residual fuel oils. Note 1: Test Method D6021 is one of three test methods for quantitatively measuring H2S in residual fuels: 1) Test Method D5705 is a simple field test method for determining H2S levels in the vapor phase. 2) Test Method D7621 is a rapid test method to determine H2S levels in the liquid phase. 5.3 H2S concentrations in the liquid and vapor phase attempt to reach equilibrium in a static system. However, this equilibrium and the related liquid and vapor concentrations can vary greatly depending on temperature and the chemical composition of the liquid phase. A concentration of 1 mg/kg (μg/g) (ppmw) of H2S in the liquid phase of a residual fuel can typically generate an actual gas concentration of >508201;μL/L(ppmv) to 100 μL/L(ppmv) of H2S in the vapor phase, but the equilibrium of the vapor phase is disrupted the moment a vent or access point is opened to collect a sample. Note 2: Because of the reactivity, absorptivity, and volatility of H2S any measurement method only provides an H2S concentration at a given moment in time. 1.1 This test method cover......
