I'm currently looking at an offshore gas field with processing to feed lean gas to an onshore LNG facility. The offshore facility carries out dehydration and HC dewpointing to achieve the required pipeline water and dewpoint specifications.
There is a potential issue with BTEX arriving at the LNG facility, and I'm trying to quantify the ppm levels into the plant. What I'm unsure of is how much confidence I can have in what HYSYS is telling me. As we are down to PPM levels, can I trust the partitioning of BTEX into the condensate stream offshore? Or should I be considering some margin? Are there alternative ways or norms/standards for estimating BTEX carryover?
Any help much appreciated.
Thanks
