In-brief analysis

September 17, 2024

The heat content of dry natural gas delivered in Texas, which uses the largest volume of natural gas in the United States, was among the lowest nationwide in 2023, averaging 1,018 British thermal units per cubic foot (Btu/cf), or 1.7% below the national average (1,036 Btu/cf), according to our Natural Gas Monthly.

The heat content of natural gas is an indicator of its composition and quality and can vary greatly depending on the geology of the producing basin. Wet natural gas is composed primarily of methane, which has a heat content value of 1,010 Btu/cf, as well as other hydrocarbon gases, mainly ethane and propane. Ethane has a heat content of 1,770 Btu/cf, and propane has a heat content of 2,516 Btu/cf. When there is more ethane and propane, the average heat

Synopsis

The Analysis Program supports research in analysis. Areas of current activity include complex, harmonic, and real analysis; dynamical systems and ergodic theory; functional analysis; mathematical physics; operator theory and operator algebras; partial differential equations and calculus of variations.

Conferences

Proposals to the Analysis Program for conferences or workshops must be submitted through the program solicitation “Conferences and Workshops in the Mathematical Sciences” (link below).  Principal Investigators should carefully read the solicitation to obtain important information regarding the substance of proposals for conferences, workshops, and similar activities.

To facilitate timely notification of the availability of support, proposals for conferences, workshops, and similar activities should be submitted 8 months in advance of the start date of the proposed event.
