WebTable 1 summarizes the sources used for LHV calculation as they are reported with a letter in the last column of Table 2. If the flow name in the source shows some differences in comparison with the name of the impact factor, a clarification is added representing the name of the flow selected in the sources. Table 1: Sources for LHV calculation WebThe Process. Waste streams are collected from different refining and chemical plant processes and sent to the flare stack for destruction. US EPA code 40 CFR 60.18 states that for optimum destruction efficiency in the flare, the waste stream must have a minimum lower heating value (LHV) of between 200-300 BTU/SCF. plot of movie babel
