Sentence examples for biogas injection from inspiring English sources

Recommendations to enhance mixing effectiveness are given: (i) a lower gas mixing input power can be used in the digester modelled within this work without a significant change in mixing quality, and (ii) biogas injection should be periodically switched between different nozzle series placed at different distances from the centre.

For 1 L of wastewater treated after ammonia stripping, the pH can be neutralized to about 7 from greater than 11 through biogas injection at 1 L/min for less than 30 min, and continuous injection does not decrease the pH.

In this study, ammonia stripping was optimized for pretreating anaerobic digestion effluent from an anaerobic digestion plant, and the possibility of using CO2 stripping and biogas injection for adjusting the pH of the effluent before and after the ammonia stripping process was also investigated.

Additional mixing by biogas injection at the bottom.

Options like biogas upgrading and injection into the natural gas grid would allow making use of existing infrastructure that can serve as a storage system for biogas, comparable to the concepts for power to gas (P2G) [65].

It appears that the more the electricity is expensive, the longer the operation time of the methanation process must be to be competitive with injection of methane from biogas.

After pretreatment in the oil separator tank, 55.6% of waste oil in raw POME could be recovered and sold and anaerobically digested through 2 AnaEG reactors followed by a dissolved air flotation (DAF); average COD reduced to about 3587 mg/L, and biogas production was 27.65 times POME injection which was used to generate electricity.

The model for the waste-to-energy project is OptimaBio's three-farm project in North Carolina that collects biogas streams at a common refinery for injection into a local natural gas pipeline.

A more recent method becoming increasingly popular is to upgrade biogas, resulting in pure methane for gas grid injection, provision of a low-pressure gas supply to the community or for use as a vehicle fuel.

Biogas has traditionally been used either for thermal or electric power purposes, or even for injection into the natural gas grid after cleaned of impurities.

For injection of bio-methane into the gas distribution network it is necessary to remove CO2 from the biogas so that a richer CH4 stream is injected to satisfy gas network requirements.
