Offshore Rig Flare-up Control System Highlighted
configured as a double-flow machine and provides the inlet flow capacity of a compressor much larger in size. In high pressure service on each module, the DATUM I compressors incorporate Dresser-Rand proprietary rotary separator technology within the compressor body to remove liquids from the incoming gas stream which eliminates the need for conventional external separation equipment. The DATUM I compressor is part of the DATUM ICS (Integrated Compression System) which integrates rotary separator technology, together with a high-speed, close-coupled, gas-cooled motor; magnetic bearing rotor system; dedicated

of hydrocarbons in water. The HydroCO2 and HydroCH4 products utilize a flat hydrophobic membrane that forms a semi permeable phase boundary between full ocean depth pressures and the interior of the instrument. Dissolved gasses in the water pass into an equilibrated internal headspace in the form of a gas stream. Concentration of CO2 or CH4 in the gas stream is quantified using an industry standard non-dispersive infrared detector (NDIR-detector) and the principle of absorption spectrometry (1). To overcome the temperature dependency of the NDIR sensors, the detector is temperature stabilized and
