Process Engineering Considerations for CO2 Transport in Pipelines: CO2 Properties, Design Practices, and Re-use of Existing Oil and Gas Pipelines
Includes a Live Event on 05/26/2022 at 1:00 PM (EDT)
This presentation will cover several aspects of CO2 transport via pipeline. The presentation will start with a high-level comparison of natural gas transport vs. CO2 transport in pipelines, highlighting key similarities and differences that may impact the processing requirements upstream of the pipeline and the design of the pipeline itself. This comparison will serve to frame the remainder of the presentation which will focus on specific aspects of CO2 transport in pipelines. The first aspect of CO2 transport that will be covered is pre-conditioning of CO2 prior to transport, including a brief review of common impurities and processing options. This will be followed by a review of CO2 properties and phase behavior as they relate to transport of CO2 via pipelines. This review will include discussion of “typical” CO2 transport conditions, impacts of impurities on CO2 phase behavior, and any specific risks or challenges associated with transporting CO2 via pipeline. A general overview of pipeline design considerations (from process engineering perspective) will also be covered in the presentation. Specific examples, case studies, or operating scenarios may be reviewed to substantiate points in the preceding topic areas. Finally, the presentation will close with a discussion of the potential to re-use existing natural gas pipelines for CO2 transport.

Dr. Darshan Sachde
Dr. Darshan Sachde is a Senior Process Engineer with Trimeric Corporation. Dr. Sachde has over 10 years of experience as a chemical process engineer, approaching six years with Trimeric. In addition to broad process engineering experience in oil refining, gas treating, sulfur processing, polymer processing, and semiconductors, he has a depth of experience in CO2 capture and sequestration (CCS). Specifically, he has supported CCS projects from early-phase concept development through FEED engineering, covering technical aspects including a variety CO2 capture technology, CO2 compression and purification, and CO2 transport by pipeline and other means (e.g., trucks). Recent relevant work includes supporting the University of Texas Bureau of Economic Geology (UT BEG) in evaluating re-use of existing oil and gas infrastructure in the Gulf of Mexico for CO2 transport and supporting several commercial clients in the evaluation of CO2 source to sink project evaluation and development.
Dr. Sachde obtained his B.S. and PhD in Chemical Engineering from the University of Texas at Austin with his doctoral work focused on process development and simulation of amine scrubbing processes. He currently resides in the Austin, Texas area.
