Project Description

The objective of this Pratt & Whitney Rocketdyne project is to develop fuel feed technology for high-pressure gasifiers that will result in significantly lower-cost coal gasification plant construction and/or operation for power production with carbon capture. Aerojet Rocketdyne will conduct dry solids pump (DSP) feed system test operations at 400 tons per day (up to 600 tons per day [tpd]), collect and analyze the resultant data, and develop and update the models needed to prepare a conceptual design of a 1000 tpd DSP operation. This project will provide researchers with the test data, analytical models, and operational experience needed to confidently design a 1000 tpd high-pressure DSP system.

Project Benefits

This project will develop a high-pressure dry feed pump for gasification processes to enable feeding of low-rank coal by constructing, operating, and testing a pre-commercial-scale prototype (600 tons per day at a pressure gradient of 1,000 psi). Novel dry feed technologies have the potential to significantly improve the efficiency of gasification in two ways; enabling slurry-fed gasifiers to run effectively on low rank coal, and enabling dry-fed gasifiers to run at high pressure. This would increase the efficiency of the gasifier and reduce plant capital, maintenance, and operating costs, resulting in less than half the life-cycle cost (capital and operating combined) of the state-of-the-art dry solids lock hopper feed system, and is also expected to perform with at least twice the mechanical efficiency of conventional feed systems.
