This paper gives an overview of electron beam dry scrubbing (EBDS) to remove SOx and NOx from flue gases of coal-fired power plants. It also describes the e-SCRUB program, a program currently underway to commercialize this process with an integrated pulsed electron beam. The electron beam, together with injected water and ammonia, causes chemical reactions which convert the SOx and NOx into commercial grade agricultural fertilizer, a usable byproduct. The e-SCRUB facility is a test bed to demonstrate the feasibility and performance of a repetitive, reliable pulsed electron beam generator operating at average power levels of up to 1 MW. This facility contains the electron beam generator and all the auxiliary and support systems required by the machine, including a computer driven central experiment control system, a 100,000 SCFM flowing dry nitrogen load which simulates the characteristics of a power plant flue, and a 2 MVA dedicated electrical service to power the machine. The e-SCRUB electron beam machine is designed to produce an 800 kV pulsed electron beam with a repetition rate of 667 pps. The energy per pulse deposited into the flue gas is approximately 750 J. The pulsed power system converts the utility power input to a 667 pps, 800 kV pulse train which powers the electron gun. The functional units of the pulsed power system will be discussed in the paper, along with some preliminary experimental results.
