system_loss_arencibia_scfm, xv_623_scfm_netof_cust_loss, system_loss_cust_scfm

Apply category to gas loss:

• xv_623_scfm_netof_cust_loss is residual xv_623 loss that we aren’t otherwise bucketing in another loss category
• system_loss_arencibia_scfm is arencibia-faulted system loss
• system_loss_cust_scfm is customer-faulted system loss

Flow through xv_1109a_scfm, xv_1109b_scfm, xv_802_scf and xv_721_scfm is determined to be venting through xv_623 if the pressure in HXR_600 is above the xv_623 pressure set point, and therefore xv_623 will be open during that time period.

formula

• xv_623_scfm_netof_cust_loss = xv_623_scfm - (xv_1109a_scfm + xv_1109b_scfm + xv_802_scfm + xv_721_scfm if PT601 >= XV623SPH)
• system_loss_arencibia_scfm = xv_623_scfm_netof_cust_loss + sv_205_out_scfm_atm + sv_1207_scfm + xv_1005_scfm + xv_523_out_scfm + sv_725_scfm + denitro_purge_scfm - xv_208_scfm
• system_loss_cust_scfm = xv_806_scfm + (xv_1109a_scfm + xv_1109b_scfm + xv_802_scfm + xv_721_scfm if PDT603ALT <= 10 OR PT601 >= XV623SPH)

special case:

When ARS16005 and PT603 < 5:

• system_loss_arencibia_scfm = sv_205_out_scfm_atm + sv_1207_scfm + xv_1005_scfm + xv_523_out_scfm + sv_725_scfm + denitro_purge_scfm
• system_loss_cust_scfm = system_loss_cust_scfm + xv_623_scfm_netof_cust_loss
