Chemically reactive membrane crystallisation reactor for CO2–NH3 absorption and ammonium bicarbonate crystallisation: Kinetics of heterogeneous crystal growth

Bavarella, Salvatore; Brookes, Adam; Moore, Andrew; Vale, Peter; Di Profio, Gianluca; Curcio, Efrem; Hart, Phil; Pidou, Marc; McAdam, Ewan J. (Elsevier, 2019-11-22)

The feasibility of gas-liquid hollow fibre membrane contactors for the chemical absorption of carbon dioxide (CO2) into ammonia (NH3), coupled with the crystallisation of ammonium bicarbonate has been demonstrated. In this ...
Chemically reactive membrane crystallisation reactor for CO₂ separation and ammonia recovery.

Bavarella, Salvatore (2018-10)

This thesis introduces an integrated system comprised of a thermal stripper and a hollow fibre membrane contactor (HFMC) for concentration of ammonia (NH₃ ) from wastewater and control of chemically mediated membrane ...
Data supporting: 'CO2 absorption into aqueous ammonia using membrane contactors: Role of solvent chemistry and pore size on solids formation for low energy solvent regeneration'

Bavarella, Salvatore; Luqmani, Ben; Thomas, Navya; Brookes, Adam; Moore, Andrew; Vale, Peter; Pidou, Marc; McAdam, Ewan (Cranfield University, 2022-10-13)

Solids formation can substantially reduce the energy penalty for ammonia solvent regeneration in carbon capture and storage (CCS), but has been demonstrated in the literature to be difficult to control. This study examines ...
Is chemically reactive membrane crystallisation faciliated by heterogeneous primary nucleation? Comparison with conventional gas-liquid crystallisation for ammonium bicarbonate precipitation in a CO2-NH3-H2O system

Bavarella, Salvatore; Hermassi, Mehrez; Brookes, Adam; Moore, A.; Vale, P.; Di Profio, G.; Curcio, E.; Hart, P.; Pidou, Marc; McAdam, Ewan (American Chemical Society, 2020-01-27)

In this study, membrane crystallisation is compared to conventional gas-liquid crystallisation for the precipitation of ammonium bicarbonate, to demonstrate the distinction in kinetic trajectory and illustrate the inherent ...
Recovery and concentration of ammonia from return liquor to promote enhanced CO2 absorption and simultaneous ammonium bicarbonate crystallisation during biogas upgrading in a hollow fibre membrane contactor

Bavarella, Salvatore; Hermassi, Mehrez; Brookes, Adam; Moore, A.; Vale, P.; Moon, I. S.; Pidou, Marc; McAdam, Ewan (Elsevier, 2020-01-27)

In this study, thermal desorption was developed to separate and concentrate ammonia from return liquor, for use as a chemical absorbent in biogas upgrading, providing process intensification and the production of crystalline ...
