I want to use Syngas coming out of the gasifier in a gas engine. Therefore Tar and Water vapour must be removed as much as possible. Syngas temp. is 450 C and Pressure is 1 atm.
Please, answer if you have some inputs or papers to solve this. Thanks.
You can do it using a filter in the gas-passage way and reheating the syngas before utilizing it.
Hi there,
You need to design and set up a syngas cleaning system, which removes tar through various thermal (high temperature cracking), chemical (solvents) or physical methods (scrubbers).
Typically, the fuel gas mixture is passed through wash bottles contain tar removing solvents such as isopropyl alcohol. Thermal cracking is done at high temperatures above the tar dew point temperature. Hope this helps...
Best regards,

Hello Anand,
I let you some information of OLGA technology developed in Netherlands:

Thanks everyone. If you can provide with specifics it would help. Since the application for Syngas will be in an IC engine,, using thermal crackling is not cost effective. Also reheating will also consume more energy as anyway gas will stored in the tank via compresser at around 6-7 atm. So anyway it will cool down. Plus in IC engine application hot gas would not help.
Andrea Lache M Thanks for OLGA papers. I went through it.. Actually I need more detailed process for my research thesis. So that I can provide with scrubber inlet and outlet temp and Gas inlet and outlet temp. Any lead on that?
Thanks in advance.
You need to define the composition of your gas, the permanent gases - CO, CO2, CH4, H2, CxH2x, CxH2x+2, up to x=6, dust levels, tars and any other trace contaminants.
To give you an idea, I've simplified producer gas cleaning to a hot gas filter to remove dust and some tars; then cool the gases in a shell and tube heat exchanger, dropping out the water and phenolics and some trace tars and then a final fabric filter to remove any trace aerosols.. The best alternative to the fabric filter is to use a wet-walled electrostatic precipitator to remove 99.99wt% of the tar aerosols and deliver clean producer gas to gas engines. I've done this on several projects.
