Abstract
Disclosed is a method for reducing methane emission from slurry produced in a livestock farm. The method comprising the steps of guiding unheated slurry from the livestock farm to a slurry heat exchanger, raising the temperature of the unheated slurry in the slurry heat exchanger to at least 65⁰ Celsius, guiding the at least 65⁰ Celsius hot slurry to an intermediate slurry tank, raising the temperature of the heated slurry to at least 75⁰ Celsius in the intermediate slurry tank, guiding the at least 75⁰ Celsius hot slurry through the slurry heat exchanger to exchange heat with the unheated slurry to raise the temperature of the unheated slurry to the at least 65⁰ Celsius and to cool the at least 75⁰ Celsius hot slurry to at least below 40⁰ Celsius, and guiding the at least below 40⁰ Celsius cold slurry to a slurry reservoir. Furthermore, a slurry treatment plant for reducing methane emission from slurry is disclosed.
