Calgren Dairy Fuels Biogas Plant Piping
Pixley, CA
|
The Calgren Dairy Fuels Biogas Plant collects manure-derived digester gas from local dairies. The biogas is conveyed through an underground piping network to the plant site where it is desulfurized, compressed and used as fuel for an onsite gas turbine and duct burner. Some of the gas is rendered pipeline quality by removing the CO2, further compressed and injected in the local utility pipeline. Electrical design services included the development of a self-regulating heat trace system for several pipelines.
PID was responsible for the piping design, layout, stress analysis and development of construction drawings for the piping installation. The plant came on stream in mid-2018.
