Revamping Gas Facilities for a Greener Future: Transforming Brownfields into CCS Hubs – The Kent Way

Brownfield modifications to convert existing gas production facilities for CCS operations

Speaker:

Christopher Jones has 13 years of experience in process engineering and currently is a Principal Process Engineer at Kent PLC. He underwent an accelerated Honours (First Class) program at university in chemical engineering and completed an internship in Germany. Chris has been exposed to a wide breadth of industry projects allowing him to apply unique design approaches when tackling challenges in traditional oil and gas and emerging new energy industries.

Abstract:

In recent years, traditional oil and gas operators have found novel means of extending the life of their assets and deferring onerous decommissioning costs by converting their facilities from gas production into carbon dioxide (CO2) injection. While the task of designing for CO2 may sound simple, CO2 injection works in counter-intuitive ways, with previously established heuristics derived from years of experience in gas condensate systems being quickly challenged as potentially dangerous. The world of designing CO2 systems is back-to-front compared with hydrocarbons; it isn’t simply a case of a change in flow direction.

Some of the design challenges explored in this presentation include: large density variability in CO2 systems where a small change in the ambient temperature can significantly impact the pressure of a shut-in system; optimal pressure ratings of the vents and drains systems and how previous safety margins may be unsafe; pipeline hydraulic modelling focussed on new areas outside of the traditional suite of analysis, such as assurance of the supercritical phase; understanding liquid water dropout; and what to modify in an existing gas-condensate production system.
