Biogas Plant Safety
It is immensely important that biogas plants are operated safely, given the highly complex process engineering involved and the fact that highly flammable gases are produced and stored. However, if the appropriate protective measures are taken, hazards in and around biogas plants can be limited and reduced to the extent that the potential threats are manageable and the plant is operated in the intended manner.
The first step for safety management is to identify hazards. In a biogas plant, following hazards are common:
Hazardous substances, such as chemicals (acid, caustic, iron sponge etc.), biogas(especially H2S);
Biological agents, such as sewage sludge, manure, animal wastes may cause hazard to human health;
Hazards from electrical equipment;
Explosion and fire hazards;
From the hazards identified, technical, organisational and personal protective measures are designed to minimise the risks.
We will explore the hazards from biogas and explosion in more detail, and introduce the commonly required technical controls at several key plant areas.
