753 - Pilot Scale Fluidised Bed Pressurised Gasifier

Tender description

The Energy & Bioproducts Research Institute (EBRI) at Aston University is seeking to acquire a small-scale fluidised bed pressurised gasifier for the conversion of solid biomass feedstocks into syngas and solids (ash and char). This system will form part of their integral research programme looking at low carbon hydrogen production. To meet the institute requirements, the gasifier must meet the following criteria: • This unit is to work independently and with some flexibility in terms of processing capacity and other operational parameters (pressure, feedrate, and temperature). • Processing capacity between 20-200 g/h and capable of operating at pressures between atmospheric and up to 10 bars. The reactor should be able to process different feedstocks (coal, petcoke, biomass, etc), therefore a suitable and flexible feeding system should be in place. • The system should be able to switch between pyrolysis and gasification modes (i.e. work at different temperatures and fluidising agents). • The operating temperatures should be minimum 850 °C, with flexible heating rate and temperature accuracy of ±1 °C. • The system should have all the suitable control systems in place to monitor the hydrodynamics of the reactor during operation. • The unit should have in place a cyclone for separation of gas and solids, a heat exchanger for gas cooling and high temperature filters suitable to work in the pressure range for removal of finer particles. Suitable relief valves, pressure control valve, gas detection and automatic shutdown valves should be in place and described. The full project specific requirements and equipment specification can be found within the project question set on Aston University’s e-tendering portal ProContract under Section 11 – Project Specific Requirements.
