hi,
I have two different boilers, namely B 6203 and B 1104. B 6203 is a dual burner system, can use fuel oil or natural gas, while B 1104 is can only fuel oil. Fuel oil used on those two boilers is the same, a marine fuel oil (MFO) with viscocity 15,21 cst (on 100 degree Celcius).
When used...
hi,
I have a problem with the pH of cooling tower at ammnonium sulfate (ZA) plant. The normal operation is 7.3-7.8. The make up water is 7.8. Starting from december 25th, the pH is decreasing until 6. There is an online pH analyzer that monitoring pH and a sulfuric acid pump that will work if...
Hi,
Can we calculate the cycle number of boiler based on conductivity?
If I calculate it based on Silika content, the cylce number of my boiler with P 35 kg/cm2 only 6. SiO2 inlet 0.1 ppm, silica in boiler water 0.6 ppm. the maximum silica permitted in boiler water is 10 ppm. I think that the...
hi..
I have a CO2 stripping tower in my ammonia plant.there is a quench water pipe taken from the middle of the tower (at about 60 m from the ground) that will be pumped and cooled by PHE and then back to the top of the tower.
The temperature of the quench water out of tower is about 102 C(it's...
hi..
do anybody knows the heat of reaction released from this reaction at 298 K:
NH3 (l) + H2O (l) --> NH4OH
I know that NH4OH is not a stable condition,will be decomposized and NH3 n H2O are formed.I am trying to calculate from the heat of formation (Hf) every component but i got some problem...
