NPE uses several technologies in its processes.
These technologies have been reviewed by numerous third parties including independent engineers and the U.S. Departments of Agriculture, Energy and Defense. In all cases, the technologies met or exceeded all test and operational criteria, and in many cases were judged to be superior to other similar technologies. Key design features are as follows:
STEP 1: First, incoming Municipal Solid Waste (MSW) is separated and processed. The Mixed Waste Processing Facility will be fully automated and will maximize the recyclable separation (see Feed Stocks and Mixed Waste Processing);
STEP 2: Next, food wastes, organics, textiles and non-recyclable paper and plastics are gasified (see Manufacturing Steps). Through NPE’s gasification platform, the technology has the unique ability to process a diverse range of feedstocks;
Due to the thermal and carbon capacity of the fluidized bed in NPE’s steam reformer, the system easily absorbs fluctuations in varied feedstocks and moisture, generating stable and consistent syngas;
Syngas clean-up starts within the steam reformer by means of process conditions and reactions: complex contaminants are reduced to forms easily removed in downstream processes;
STEP 3: Contaminants are removed from the syngas. The gasification island is fully integrated with novel new downstream processes that remove contaminants down to a parts per billion level (again, see Manufacturing Steps);
STEP 4: A highly efficient fixed bed Fischer-Tropsch (FT) reactor is used to convert syngas into FT syncrude, which then goes through a fuel upgrading process to produce renewable, sulfur-free diesel transportation fuel (again, see Manufacturing Steps).
