Down Hole Sulphur Removal and Recovery

Total and CrystaTech are developing a regenerable solvent based process to prevent the formation of sulphur deposition<br>during production in natural gas well bores or even in the surface circuits and facilities. While producing gas from certain<br>formations, solid sulphur has been observed to deposit on the well tubing which causes gas production to diminish and<br>ultimately stop. Such scenarios can result in production time losses ranging from one day for batch treatment to three days for<br>coiled tubing cleaning.
