Overview
The CCS toolbox has been created to provide a selection of calculators to assist in framing some of the key issues around CCS which occur at the beginning of a project. Specifically:
- CO2 Properties
- Pressures and Temperatures on a phase diagram
- Pressure and Temperatures on a hydrate diagram
- CO2 properties at different pressures and temperatures
- Joule-Thomson cooling effects
- Metallurgy selection
The toolbox is not intended to replace rigorous engineering design, but rather to provide a quick and easy check on a number of parameters that are useful to understand whether framing the project or assisting in detailed design.
CO2 Properties
The CO2 properties table is a static table of key CO2 properties for reference purposes. A toggle switch has been provided to switch between metric (deg. C and bar) and Imperial (deg. F and psi) where applicable.
Phase Envelope
Plotting key pressure and temperature points on a phase envelope can give insight into the potential challenges that may be encountered in the wellbore. In particular where in the system there may be a phase change, for example between the arrival P&T and the required wellhead P&T – with potential for Joule -Thomson cooling. Simply enter the pressures and temperatures for each of the points in the input grid and the graph will update automatically. The graph can be shared be using the share button at the top-right of the screen.
Hydrate Envelope
Similar in functionality to the Phase Envelope, the hydrate envelope plots the points against a hydrate curve to help identify
CO2 Properties (Density and Viscosity)
The impact of phase change in CO2 results in a significant change in the properties.
Joule-Thomson Cooling
The impact of Joule-Thomson cooling as a result of the rapid pressure drop in CO2
