Description

Through experiments, the relevant data of the sludge pyrolysis treatment process under different working conditions are collected and distributed, and the input and output of materials and energy in each process are quantified, and the environmental pollutant emissions are quantified. Users of this data set should consider the specific application of this process as it relates to municipal sludge with a moisture content of 80%. When modeling lifecycle impacts, take into account the energy consumption and emissions associated with the pyrolysis at 450°C. The data is representative for the given conditions and should not be extrapolated to sludge with different characteristics or treatment processes without proper adjustments.

Technology

The rated power of the tube furnace in the pyrolysis link is 4 kW, the no-load power is 1.4 kW, nitrogen is introduced for 2~3 minutes before the reaction to ensure an oxygen-free environment, the nitrogen flow rate is 30 ml/min, the heating rate of the tube furnace is 80 °C/min, and the final temperature of pyrolysis is maintained for 10min.
