“…To begin with, a survey of previous studies was made to help identify the full range of possible process flow schemes available for the liquefaction process. Based on a review of the studies mentioned in the introduction [6,7,10,[13][14][15][16][17], three were selected as the basis for further work that covered all of the principle flow scheme alternatives: Alabdulkarem et al [16], Seo, et al [10], and Ø i, et al [17]. From these three studies, four 'base' flow schemes were then selected.…”

“…The IPCC special report on CCS [1], for example, identifies shipping as the lowest cost option for distances over liquefaction of CO2 in more detail. Although the majority of work is focused on either open cycle CO2 processes or closed cycle NH3 refrigeration processes [6,7,10,13,14], others have also studied more novel approaches such as the use of absorption refrigeration [15], cascade refrigeration [16], and the application of turbo expanders [17]. Some have also compared a broad range of schemes.…”

“…Decarre et al [7] compared liquefaction at 7 bara and 15 bara, finding that transportation at 15 bara offers both lowest cost and lowest energy consumption. Seo et al, over the course of two papers [10] and [18], also studied the optimum liquefaction pressure conditions finding that the overall cost was lowest for 15 bara cases. More generally, both Seo et al [18], Alabdulkarem et al [16] and Jackson et al [13] found that the optimum liquefaction pressure for the transportation of CO2 by pipeline to be around 50 bara, which is well above the practical limits for ship based transport.…”

In CCS projects, the transportation of CO2 by ship can be an attractive alternative to transportation using a pipeline, particularly when the distance between source and disposal location is large. However, the energy consumption of the liquefaction process can be significant, making the selection of an energy-efficient design an important factor in the minimization of operating costs. Since the liquefaction process operates at low temperature, its energy consumption will vary with ambient temperature, which could be a factor that influences the trade-off point between pipelines and shipping in different geographic locations. A consistent set of data showing the relationship between energy consumption and cooling temperature is therefore potentially useful to CCS system modelling. This study compares the performance of a wide range of CO2 liquefaction schemes. It applies a methodical approach to the optimization of process operating parameters and studies performance across a range of operating temperatures. A set of data for the minimum energy consumption cases is presented. The main findings are that open-cycle CO2 processes often offer minimum energy consumption; NH3 based schemes often offer better performance at higher ambient temperatures; and that for the cooling temperature range 15 to 50 °C, the energy consumption for the best performing liquefaction process rises by around 40%.

Abstract:In this study, a techno-economic model was used to calculate the costs of CO2 transport and specify the major equipment required for transport in order to demonstrate and implement CO2 sequestration in the offshore sediments of South Korea. First, three different carbon capture and storage demonstration scenarios were set up involving the use of three CO2 capture plants and one offshore storage site. Each transport scenario considered both the pipeline transport and ship transport options. The temperature and pressure conditions of CO2 in each transport stage were determined from engineering and economic viewpoints, and the corresponding specifications and equipment costs were calculated. The transport costs for a 1 MtCO2/year transport rate were estimated to be US$33/tCO2 and US$28/tCO2 for a pipeline transport of ~530 km and ship transport of ~724 km, respectively. Through the economies of scale effect, the pipeline and ship transport costs for a transport rate of 3 MtCO2/year were reduced to approximately US$21/tCO2 and US$23/tCO2, respectively. A CO2 hub terminal did not significantly reduce the cost because of the short distance from the hub to the storage site and the small number of captured sources. OPEN ACCESSEnergies 2015, 8 2177

With the development of the third oil recovery in oil fields and CO2 capture, utilization and storage (CCUS) technology, CO2 injection has become an effective means to enhance oil recovery (EOR) and relieve the greenhouse gas effect. The CO2 pipeline transportation technology started relatively late in China, where the gas phase and liquid phase transportation are widely used methods. The CO2 hydrate formation in the process of transportation may reduce the valve, destroy the equipment and even cause pipeline ice blockage, but research in China on CO2 hydrate is not very extensive. In this paper, the CO2 hydrate formation conditions were simulated using HYSYS, and the simulation results were compared with the experimental results to verify the feasibility of the simulation method. Based on this, factors in the influence of gas impurities on CO2 hydrate formation are simulated, and the pipeline transportation process of CO2 hydrate formation are predicted. The results show that when there is a low amount of impurity content, the gaseous impurities such as CH4, N2, H2, O2, have little effect on CO2 hydrate formation in gaseous CO2 pipeline transport. Furthermore, environmental temperature has little effect on the changes in pipeline pressure along the transport route. However, with a change in environment temperature, temperature along the pipeline changes greatly. CO2 will change from a gas state to a liquid state in the pipeline when the ambient temperature is low. In the case of low ambient temperature, a thick insulation layer should be used, and heating of the pipeline may also be required. When the ambient temperature is higher than about 10℃ , there will be no hydrates formed in the pipeline.
