“…It has also been found that H 2 impurity can substantially reduce the density at temperatures in the vicinity of the CO 2 critical point 207 and this must be accounted for in determining pipeline capacity and compressor duty. 208 Seevam et al , 209 have simulated the effects of impurities on the pressure drop and temperature profiles along pipelines. For one scenario involving a 3 mol% H 2 impurity, the maximum distance between compressor stations was found to decrease from 300 km to 105 km.…”

“…So far, CCUS transportation infrastructure framework usually consists of pipelines, in addition to compressors and booster pumps. Okezue and Kuvshinov [16] introduced a tool that assists in the selection and sizing of centrifugal compressors and booster pumps to be installed on a supercritical carbon dioxide transport pipeline. A quasi-dimensional model that studies the effect of various impurities on the performance of a centrifugal machine handling supercritical CO 2 of varying purity was introduced in this regard.…”

Carbon integration aims to identify appropriate CO2 capture, allocation, and utilization options, given a number of emission sources and sinks. Numerous CO2-using processes capture and convert emitted CO2 streams into more useful forms. The transportation of captured CO2, which poses a major design challenge, especially across short distances. This paper investigates new CO2 transportation design aspects by introducing pipeline merging techniques into carbon integration network design. For this, several tradeoffs, mainly between compression and pipeline costs, for merged pipeline infrastructure scenarios have been studied. A modified model is introduced and applied in this work. It is found that savings on pipeline costs are greatly affected by compression/pumping levels. A case study using two different pipe merging techniques was applied and tested. Backward branching was reported to yield more cost savings in the resulting carbon network infrastructure. Moreover, both the source and sink pressures were found to greatly impact the overall cost of the carbon integration network attained via merged infrastructure. It was found that compression costs consistently decreased with increasing source pressure, unlike the pumping and pipeline costs.
