... Abstract Controlled Freeze Zone™ is an efficient single-step cryogenic distillation process for the removal of carbon dioxide, hydrogen sulfide and other impurities from natural gas. Rather than avoiding the freezing of CO 2 at cryogenic temperatures, the solidification is allowed to take...

... as the main option to discard the captured CO 2 more sustainable option are emerging where CO 2 is used as a feedstock. A number of options for CO 2 utilization are evaluated, and one of the most promising options, biofixation of CO 2 by microalgae, is discussed in detail. One of the main aspects...

... Sumatra, Indonesia. The plant is designed to process 93 MMSCFD of sour natural gas, reducing CO 2 from 38% to 4% mole and H 2 S from 350 ppmv to 4 ppmv. Singa plant becomes the unique hybrid configuration for AGRU as it consists of Membrane Unit and Amine Unit operating in parallel. Each unit is designed...

... gaseous streams and solvents at elevated pressures is relevant for a number of applications. This includes processes like pre-combustion capture, with the main focus on the separation of CO 2 and H 2 mixtures, and natural gas treatment, where CO 2 is removed from CH 4 . A comparison is made between...

.... 33 , p. 359 – 377 . Abstract Cyclic steam EOR pilot project has been deployed in sandstone reservoir type, heavy oil field of Petroleum Development Oman, South Operation, and recently within August to October 2011 showing an interesting CO 2 increase from 1% to the level of 25% mol in gas...

... technology using CO 2 tracer was implemented as a pilot project in eleven gas lifted wells offshore fields Dubai. The results show that this method is very effective for the quick and reliable determination of lift gas entry points in the well. The method can detect the operating lift depth, detect multiple...

... a workover program converting gas producers to CO 2 injections. Because the oil in place had the potential to equal that of the remaining oil in the reservoir, the optimal approach would require a solution that prevented sacrificing hole size. Solid expandable tubular systems installed in more than 25 wells...
