*U.S. Department of Energy “W.A. Parish Post-Combustion CO2 Capture and Sequestration Project Final Environmental Impact Statement Volume I” (Feb, 2013), DOE/EIS-0473

Client : Casale SA / Metafrax

Location: Perm, Russia

Capacity: 1,200 TPD

Feed Gas: Methanol Plant Reformer

Process : KM CDR ProcessTM

Solvent: KS-1TM Solvent

Use of CO2: Urea (Melamine) Production

Start Up: 2021



Background & Motivation

KM CDR ProcessTM using KS-1TM is a fully commercial proven, however further reduction of CO2 capturing cost is desirable to make more CCS or CCUS projects realize.

Advanced KM CDR Process is developed as MHI’s next-generation process following after KM CDR ProcessTM technology

CAPEX: 30% reduction compared to conventional KM CDR processTM

OPEX: Lower utility consumptions (no OPEX-CAPEX tradeoffs) by new KS-21TM solvent

Commercialization is starting from new projects in the engineering stage


Feature of Next-generation CO2 capture process

Improvement from new technology & lessons learned

• DCC and Absorber are the major cost centers (>30% of CAPEX)• Reduce height of DCC by integrating DeSOx & Quenching section and

New packing • Reduce height of Absorber by optimization based on actual operation• Reduce Regenerator diameter by 10% by selecting New packing

Technology risks are significantly reduced after large-scale unit experience

Configuration

Flue gas quencher

Intercooled absorber

Multipul water wash

MHI energy saving system

Potential solvents were carefully studied and a few components were selected in terms of reaction speed, VLE, corrosiveness, thermal stability, Oxidative stability, Volatility, and manufacturing cost.

A few solvent and optimized combination of component were tested by 1st and 2nd

campaigns.


New solvent development & Features

Thermal stability• Reduce thermal degradation and allow higher stripping T and P, reducing compression

work

Oxidative stability• Potentially more tolerant to impurities • Reduce amine oxidation and HSS formation rate

Volatility• Reduce amine loss from emission and cost of water wash system• Steam consumption savings outweigh cost increases due to higher solvent circulation

Full-Scale FEED Study for Retrofitting the Prairie State Generating Station with an 816

MWe Capture Plant Using Mitsubishi Heavy Industries of America Post-Combustion CO2

Capture Technology – The Board of Trustees of the University of Illinois (Champaign,

IL) will complete a FEED study for the installation of a carbon capture system at the Prairie

State Generating Company’s (PSGC) Energy Campus in Marissa, Illinois. The project will

be based upon the Advanced KM CDR Process™ carbon dioxide (CO2) capture

technology from Mitsubishi Heavy Industries. The project team that successfully

completed the Petra Nova capture plant in Thompsons, Texas has been reassembled to

benefit from lessons learned. The Advanced KM CDR Process is an amine-based

capture system that uses the KS-21 solvent. If successful, the project would provide

valuable insight into lowering the cost of carbon capture systems.
