To obtain much higher glycol purities
Drizo™ regenerates the glycol by solvent stripping instead of the conventional gas stripping. Solvent stripping allows to obtain much higher glycol purities than gas stripping (up to 99.998 wt% instead of the typical 99.95 wt%) and consequently allows to get much larger water dew point depressions: up to 100 °C and even higher in some cases. The solvent required by the Drizo™ process is usually obtained from the BTEX present in the natural gas itself and in most cases the process will even produce some liquid hydrocarbons.
Drizo™, more than 60 references to date
With more than 60 references to date, Drizo™ has proved to be the best available glycol dehydration process. This is not only because of its higher dehydration efficiency, but Drizo™ is also an environmentally friendly process with minimized BTEX/CO2 emissions. Furthermore thanks to the minimal number of additional equipments specifically required by Drizo™ compared to conventional glycol units, the process has easily been implemented on existing glycol units, at minimal cost and with no shutdown time.
