A paper published in 'Energy & Fuels' describes more in detail the possibilities offered by POG and iPOG™
The POG has been further developed into user-friendly freeware, the Interactive Process Optimization Guidance (iPOG™), that calculates Hg emission rates from coal-fired utility plants burning any single coal or coal blend. The software requires the entry of data on coal properties, burning conditions and flue-gas cleaning configuration and conditions. With this information, the iPOG™ calculates Hg emission reductions that can be achieved with different coal pretreatments (washing and blending); with the most common pollution controls, including systems with only particle collection devices and with various combinations of pollution controls (ESP/FGD and SCR/ESP/FGD); and with Hg specific controls such as injection of conventional carbon sorbents, brominated carbon sorbents, and oxidising agents. The iPOG™ also calculates the Hg captured in the bottom and fly ashes, depending on the coal characteristics and combustion conditions (no plant emits 100% of the mercury in coal).
