Summary: A novel method was used to quantify combustion slip from natural gas compressor engines at gathering and boosting stations in the U.S. The study found that methane emission rates were lower for lean-burn engines and higher for rich-burn engines, compared to existing emission factors. Modelled results suggest that unburned methane accounts for a significant portion of methane emissions from the natural gas sector in the U.S.

Summary: Energy, exergy, and economic analysis were conducted to evaluate regasification systems in FSRUs. The seawater regasification system was found to be the most efficient in terms of energy and exergy, while the open loop propane system was cost-effective for a certain range of LNG prices. There is a need to develop more efficient configurations to utilize the cold energy of LNG, as demonstrated by the excessive destroyed exergy in current systems.

Summary: Deficiencies of energy resources, air pollution, and climate change have led to threats to energy security and human health, thus natural gas is offered as one of the most widespread alternative fuels. The experimental study injects Compressed Natural Gas (CNG) into a diesel engine and measures the exhaust total exergy and 2nd law efficiency, showing that using CNG increases the efficiency and reduces the chemical exergy of emissions. The findings indicate that replacing 20% of diesel fuel with natural gas enhances the exhaust total exergy, with maximum variation at 1200 rpm, and decreases the chemical exergy by 11.7% when recovering excess CO and unburned hydrocarbon.

Summary: This paper proposes and studies a piston-type thermally-driven pump with a structure similar to a linear compressor, aiming to eliminate the high-quality energy consumption of existing pumps and replace mechanical pumps. The coupling mechanism of working fluid flow and element dimension is analyzed based on force analysis, and experimental data analysis is used to determine the pump operation stroke. Theoretical simulation is conducted to analyze the correlation mechanism of the piston assembly. The research shows that the thermally-driven pump can greatly reduce power consumption and has potential for industrial applications.
