“…Although S-wave and P-wave velocities respond differently to temperature, composition and density, elevated temperatures lower both P-and S-wave velocities as discussed by Lebedev and Nolet (2003). Temperature effects are probably greater than compositional effects for the lithosphere and other possible causes for lowered seismic velocities such as partial melting, and presence of small amounts of volatiles such as water, or CO 2 which can be significant in many SE Asia hydrocarbon basins and may have a mantle origin (Imbus et al, 1998). All would point to a weakened continental lithosphere, or perhaps a partly absent lithospheric mantle.…”

“…Elevated nitrogen in near-surface sediments can be from the high-temperature breakdown of selected terrestrial dominated organic matter. Stable carbon and nitrogen isotopes can be used to help determine the non-hydrocarbon gas origin [22].…”

“…For example, calcium carbonate will decompose with high temperature from regional and contact metamorphism into calcium oxide and carbon dioxide when heated: CaCO 3 →CaO + CO 2 . The following papers have more details on the origin of carbon dioxide from the thermal breakdown of carbonates in sedimentary basins: Giggenbach [23], Imbus et al [22], and Wycherley et al [24].…”

Evaluation of Near-Surface Gases in Marine Sediments to Assess Subsurface Petroleum Gas Generation and Entrapment

Gases contained within near-surface marine sediments can be derived from multiple sources: shallow microbial activity, thermal cracking of organic matter and inorganic materials, or magmatic-mantle degassing. Each origin will display a distinctive hydrocarbon and non-hydrocarbon composition as well as compound-specific isotope signature and thus the interpretation of origin should be relatively straightforward. Unfortunately, this is not always the case due to in situ microbial alteration, non-equilibrium phase partitioning, mixing, and fractionation related to the gas extraction method. Sediment gases can reside in the interstitial spaces, bound to mineral or organic surfaces and/or entrapped in carbonate inclusions. The interstitial sediment gases are contained within the sediment pore space, either dissolved in the pore waters (solute) or as free (vapour) gas. The bound gases are believed to be attached to organic and/or mineral surfaces, entrapped in structured water or entrapped in authigenic carbonate inclusions. The purpose of this paper is to provide a review of the gas types found within shallow marine sediments and examine issues related to gas sampling and extraction. In addition, the paper will discuss how to recognise mixing, alteration and fractionation issues to best interpret the seabed geochemical results and determine gas origin to assess subsurface petroleum gas generation and entrapment.

“…2 37, 38. For the overall process, data about raw materials, battery limit processes, and CO 2 content were obtained from existing natural gas or oil wells, and provided a satisfactory basis of design 39–44. For the separation, relevant information on adsorption, desorption, and operation conditions was obtained from laboratory data and from previously published contributions 36, 45–47.…”

Preliminary Design of a Vacuum Pressure Swing Adsorption Process for Natural Gas Upgrading Based on Amino‐Functionalized MIL‐53

et al. 2015

A preliminary study based on a conceptual process design methodology that includes a technical evaluation and an economic study has been carried out for the use of the metal-organic framework NH 2 -MIL-53(Al) as adsorbent for the separation of carbon dioxide from methane. Among the alternatives considered, a vacuum pressure swing adsorption was chosen in the detailed design phase. The combination of a design with columns in parallel and the possibility of recirculating some of the streams ensures a high degree of separation and a final product with high quality without compromising the operation costs. A comparison with the state-of-the-art technology, amine scrubbing, and with a process based on membranes demonstrates that the proposed process is competitive as a result of its low operation costs and the energy demand.
