SYSTEM, METHOD, AND APPARATUS FOR AMELIORATING DEPOSITS IN SELECTIVE CATALYTIC REDUCTION SYSTEMS FOR THE REDUCTION OF NITROGEN OXIDE EMISSIONS IN STEAM METHANE REFORMERS

摘要

A system, method, and apparatus for ameliorating deposits in selective catalytic reduction systems for the reduction of nitrogen oxide emissions in steam methane reformers. The system includes positioning a dual stage refractory particulate (RP) filter placed in an upstream airflow from a Selective Catalytic Reduction System (SCRS). The first stage is formed of a perforated steel plate with a second stage formed of a wire mesh screen. The system may employ air cannons to clean each of the first stage and the second stages.
