Abstract

A flare system including a flare stack and a modular flare unit connected in parallel with the flare stack. The modular flare unit includes a frame, at least two energy conversion modules detachably supported by the frame, a fuel manifold, an air manifold, an exhaust manifold, and an electric generator. Each energy conversion module includes a combustion chamber configured to receive a flow of residue gas through the fuel inlet for combustion in the chamber at (or close to) atmospheric pressure, and a Stirling engine configured to convert heat from the combustion chamber into mechanical energy. The electric generator is connected to generate electric power from the mechanical energy.
