Hi

I am looking for a suitable filter to treat 250 cu.m/hr of process media comprising of 85% heavy fuel oil and 15% gasoline.
The intent is to reduce ash content from inlet of 1000 ppm to outlet of 50 ppm.

I need to make a CAPEX and OPEX comparison for various filtration technologies

Appreciate recommendations

Regards

Bala

If the particle size and density is sufficient, centrifuges would probably be your most economical option considering the volume you need to handle.

But probably not the best forum for this specific question... this forum is for fuel engineering as it relates to automobiles.

@ TugboatEngg - Would not the capex be extremely high for centrifuge compared to autobackwash filters with a standby

Presume centrifuges will also have high power consumption as a operating cost vis-a-vis catridge replacement in a filter. Plus centrifuge would also have some maintenance requirements

The initial expense of purchasing na centrifuge is quite high but the operating costs are very low.

It takes a lot of power to force fluid through filters. A centrifuge is just spinning a bowl so their power requirements are actually quite low compared to throughput. There are centrifuges with automatic sludge discharge so maintenance is minimal.
