Ignition Method Development And First Field Demonstration Of In Situ Smouldering Remediation, Grant C. Scholes Sep 2013

Ignition Method Development And First Field Demonstration Of In Situ Smouldering Remediation, Grant C. Scholes

Electronic Thesis and Dissertation Repository

Self-sustaining Treatment for Active Remediation (STAR), a smouldering combustion-based technology for remediating sites contaminated by industrial liquids, has been extensively studied in the laboratory. The technology had not been demonstrated at a real site. Moreover, the ignition method (based on heat conduction) for the process used in the laboratory was not appropriate for field deployment and an alternative was required. This work first presents the development of a new ignition method for smouldering combustion. This ignition technique (based on heat convection) was proven effective via laboratory tests, and then applied and improved through two field tests. These field tests, conducted …

Smouldering Combustion For Soil Remediation: Two-Dimensional Experiments And Modelling, Tanzeer Hasan

Electronic Thesis and Dissertation Repository

Sustaining Treatment for Active Remediation (STAR) is a novel technology for the remediation of soils contaminated with Non-Aqueous Phase liquids (NAPLs). STAR is based upon the concept of liquid smouldering, in which NAPLs embedded in a porous medium are progressively destroyed via an exothermic oxidation reaction which propagates in a self-sustaining manner through the contaminated material. The In Situ Smouldering Model (ISSM), developed to simulate the propagation of STAR as a function of NAPL content and local air velocity, was calibrated for a suite of one-dimensional experiments (MacPhee et al., 2010). However, STAR application at field sites involves propagation of …
