what reactants do u use?? check side & non required reactions in the reactor, reactants may contain some impurities that cause gas formation. foam comes from gases in liquids.
iron ions, in general, can be found as precipetated ions within 9 < PH < 1.8 under PH outside this range iron ions became soluble ... I do not know the material that flows through ur HEX but if u can manipulate PH.. this may help...
try to find good newsgroup(s), where people discuss such matters. Hydrocarbon processing journal issues some papers in each eddition, & issues manuals that assembles these papaers periodecaly.
Why d'nt u try to install a self-cleaner by ur self, find the suitable solvent for the material accumulate on strainer, install a suitable diameter pipe against the strainer...etc,of course the strainer cover should have a vent.
Asghar... have u contacted 'zigzag' valves (filter) vendor to assure thier capabilities??? they are used to settle the per min. moisture droplets in instrument air... I have experienced them...
I suggest u to install one of the following on the main line of fuel gas:
1- 'zigzag' valve if the pressure of gases is not high, the zigzag shape pull liquids down & allow vapors to go through.
2-a cheep method ( which I reccomend) is the using of Mesh (either iron mish or polyprobelen) they...
b4 flooding level rises ... as level rises ... as level increased (if the distillation tower has a side draw-off's) the properties of draw-off's differs (if petroleum industry the collours become darkers @the upper trays) & down trays become colder...
the main indication for level increasing is...
I understond that methane is mixed with water & traces of cupper... if this is the case I suggest the following:
1-separate the liq. phase mixture (water & methanol) from the solids either by using a cyclon or a suitable mesh.
2-separate the tow liq. phase can be separated either by using a...
u'll find detaled information & design in "bahra fluid engineering" publications...they have an old book named "proceedjngs of the 2nd symposium on jet pumps & ejectors and gas lift techniques" printed by cambridge in 1975...u'll find little information but good in perry's...
