Would appreciate very much any feedback on overpressure protection design for hydrocarbon liquid cartridge filters and hydrocarbon-water liquid coalescers. I am working on a system which has a cartridge filter located upstream of the coalescer to filter out any solids to prevent plugging of the coalescing element. To prevent over pressuring during external fire how many PSVs (pressure safety valves) should be installed on each vessel - one (1) on each side of the filter cartridge and coalescing element or just one (1) upstream of the elements? It seems the safer design would be to install two (2) PSVs on each vessel. If only one (1) PSV located upstream of the filter or coalescing element is used the downstream section without the relief valve may be over pressured because of possibly high pressure drop thru the element. Also, there is a possibility of filter cartridge being plugged. Would like to know about some actual design and what is the industry practice. Thanks.
