CO2 Interface Transport Interface Storage

Awarded: NOK 16.7 mill.

CO2 Capture and Storage (CCS) technology requires methods for transport of captured carbon dioxide to a storage facility. In most cases this will involve pipeline transport of liquid CO2, generally across long distances. In design of CCS, CO2 transport is the necessary link between two important interfaces: capture-transport and transport-storage. Fundamental R&D on the interfaces between capture and transport and between transport and storage is vital for a safe and cost efficient design of CCS systems. Current interface design is conservative, mainly due to lack of knowledge and references. This project aims at increasing knowledge and providing a small scale reference. The aim of this R&D project proposal is to experimentally verify and model CO2 trans port on: - depressurization of pipelines (horizontal transport) - effect of impurities, from capture to reservoir - transient multi-phase flow (horizontal transport) - heat transfer in pipelines (horizontal transport) - density, pressure, and temperature profiles in wells (vertical transport) - vertical and horizontal transport in natural gas well streams with very high CO2 concentrations (>60 mol%) The phase behavior of CO2 is significantly different from oil, natural gas and water due to the location of its critical and triple point, e.g. dry ice will form during a sudden pressure relief to atmospheric conditions. This puts requirements on design, operation, start-up, shut-down and maintenance, especially for long offshore pipelines (which are to be e xpected in Norway). Fundamental R&D on CCS chains has not yet reached the level of maturity as oil and gas chains. This project will contribute to reduce this gap of knowledge. Furthermore, it is envisaged that the rigs from this R&D projects will be used for experimental verification and modeling of high CO2 natural gas well streams at the end of this project for increasing the usefulness of the investments, and reuse of the constructed experimental rigs.
