Abstract :
Producer gas is the mixture of combustible (H2, CO, CH4) and non-combustible gases (CO2, N2) along with Tar, SPM, water vapor, mineral vapor etc. A number of methods has been designed and developed and successfully implemented for removal of Tar and SPM from producer gas, however these methods are uneconomical. Apart from that most of the developed technologies, for improving the quality of producer gas, removes only Tar and SPM from producer gas. The present research work deals with the cleaning as well as conditioning of producer gas. A Chemical hydroxide dosing based technology was developed and tested successfully. Study reveals that sodium hydroxide chemicals at 30% concentration and dosing with producer gas can increase the energy content of producer gas up to 11% by absorbing the non-combustible gases (CO2). In addition to that heating of hydroxide solution and increasing of residence time of producer gas with hydroxide solution, not only increases the cleaning efficiency (90% and 87%) of Tar & SPM present in producer gas, it also conditioned the producer gas by absorbing the CO2 at a tune of 17%, respectively.
