| Summary Integrated Synthesis Loop (ISL) Technology blends unique ammonia synthesis process engineering with conventional Makeup Synthesis Gas prepared from conventional Steam-Hydrocarbon Reforming and synthesis gas purification processes. The ISL Process works in Synthesis Loops which include multi-stage refrigeration compressors to condense product ammonia, by fully optimizing Refrigeration System loads to minimize plant energy consumption. The ISL retrofit has controls to shift loads of the synthesis and refrigeration compressors to achieve maximum capacity and efficiency advantages. The ISL retrofit works with all Ammonia Converter technologies, including reactors with internal heat-exchange between catalyst beds, ultra-high activity catalysts including rare earth elements and mechanical designs using radial bed flow, axial-radial flow or cross flow arrangements. Plants with greater ammonia conversion in the Ammonia Converter achieve higher energy saving when retrofit with the ISL Process. Only proven technologies are used in the ISL Process. The ISL Process is reliable and accommodates rapid plant start-up and is easy to understand and operate. ISL Ultra Process installations can increase production capacity. Following retrofit of the ISL Process, further increased plant capacity projects may be completed with lower capital spending. |
