Desulfurization and CCU Project

2. 2
 JET is a subsidiary of JNG based in Ridgefield Park, NJ
 JNG has 80% market shares in ammonia-based desulfurization (EADS) with 400+ installed units
 Applications
• Flue gas desulfurization in power industry
• SRU tail gas and FCC flue gas treatment in Oil & Gas industry
 Ammonia-based desulfurization and carbon capture (ADSC) technology
Technology Overview

3.  Technology developed by JNG
 Ammonia is used as the absorbent to capture SOx and CO2 in the flue gas
 SOx is converted to ammonium sulfate (AS) and CO2 to ammonium bicarbonate (ABC)
 AS and ABC are saleable fertilizers
Ammonia-based Desulfurization & Carbon Capture (ADSC) Technology

4. 4
Carbon Capture: Challenges
Process Amine-based Ammonia-based
Advantages  Proven technology for CO2 capture  Up to twice the CO2 absorption capacity
 49 – 64% less regeneration heat
 80+% reduction in solvent makeup cost
 Negligible oxidative or thermal degradation
Disadvantages  Amine: High cost and sensitive to O2, SO2
 Regeneration: High energy consumption
 Ammonia slip due to high volatility of ammonia
 Requiring post-scrubbing - cost and wastewater issues

ADSC Technology: Features
 Residual ammonia in the flue gas after decarbonization is scrubbed with desulfurization
solution, which resolves the ammonia slip issue and simplifies the process
 SO2 and CO2 in the waste stream are converted to (NH4)2SO4 and NH4HCO3 fertilizers
 Carbon capture process is simplified and CAPEX/OPEX is reduced by at least 50% compared
to the amine-based process
 By-product NH4HCO3 can be sold or decomposed to CO2 (as a product or to be sequestrated)
and ammonia (for reuse)
 Synergistic multi-pollutant control makes coal cleaner and more economical than natural gas
