Substances that could travel with condensate
1- Gases
SO2 – SO3 – H2S
2- Solid sulfur particles

Raw material can be
- Sulfur lumps pastilles produced from coke (petroleum refinery)
- pastilles produced from natural gas purification

Detection of solid particles
Experiment (1) Mix water at 80 deg C with molten sulfur lumps
Experiment (2) Mix water at room temperature with molten sulfur lumps
Experiment (3) Mix water at 80 deg C with sulfur pastilles
Results: - No change noticed in PH or TDS as the sulfur is insoluble. Turbidity unknown
- The sulfur solidifies instantly into lumps and very small particles
Below are pictures from experiment (1)

Notes:
-
Sulfur used is lumbs
-
The vessel in both cases was partially closed
-
Condensate has a light red color while feed water is clear with the following properties
T: 25 deg c
TDS: 0-15
PH: 7-7.5
