This Reaction Engineering International (REI) project will develop a better understanding of ash deposition onto refractory and metal surfaces associated with the syngas cooler used in integrated gasification combined cycle (IGCC) plants that incorporate a two-stage gasifier. Plugging and fouling of syngas coolers will be evaluated and specific mitigation methods validated. The successful completion of this project will result in improved availability and reliability of the syngas cooler and thereby improve the availability of the overall IGCC plant.

This REI project is focused on developing a better understanding of syngas cooler plugging and fouling principles, in order to formulate concepts for mitigation of these problems to improve gasification plant availability and reliability. Improvements in availability and reliability of the syngas cooler would directly reduce the cost of electricity in integrated gasification combined cycle plants and costs of other products from syngas. Specifically, REI is conducting experiments and CFD modeling to develop designs for deposit removal, with the most promising concepts to be validated during field testing.
