The installation with Lanxess represents a significant step in the commercial use of the Shell Cansolv post-combustion CO2 capture system, as it is the first deployment of the system in the chemicals production industry.
“This is yet another key milestone for Shell Cansolv as it validates our competitive edge in the development, performance, and installation of tailored process solutions,” states Philippe Gauthier, President of Shell Cansolv.
The plant in Newcastle is designed to capture 170 metric tonnes of CO2 per day. Shell Cansolv’s CO2 capture technology will be used to remove carbon dioxide from the flue gas generated by burning natural gas. The system has been incorporated into a new facility that will combust locally sourced natural gas in conventional boilers to generate steam. The captured CO2 will be used as a feedstock for chemical production and will mean that Lanxess can avoid purchasing large volumes of CO2. Shell Cansolv has supplied Lanxess with its patented process, engineering services and its patented CO2 amine absorbent.
“The strategic impact of this project is one of great importance for us since we’re currently sourcing both steam and CO2 from other facilities. The innovative use of Shell Cansolv’s technology will not only provide valuable security of supply of CO2, but will also allow us to improve energy efficiency and plant economics,” states Dr. Carsten Gerdes, Managing Director at Lanxess CISA (Pty.) Ltd.
The CANSOLV CO2 Capture System employs a regenerable technology that captures up to 90% of CO2 emissions. It is highly flexible and offers cutting edge performance, including low parasitic energy consumption, fast kinetics and extremely low volatility. Shell Cansolv also offers the CANSOLV SO2 Scrubbing System for the removal of sulphur dioxide from industrial flue gases and its integrated SO2/CO2 system.
Engineering, construction and procurement of the Newcastle plant took less than a year and a half. The EPC services were performed by local engineering firm Process Plant Technology (PPTech), a company which has been active in the South African chemical industry since 1974. PPTech has embraced the Shell Cansolv technology and assembled a team of experienced engineers on this project to apply a modern and resourceful design process.
“We have grown as a company into this project through positive interaction with Shell Cansolv from commencement through to its conclusion. The resulting plant represents a huge achievement for the PPTech team and its historic start-up is a testament to the collaborative effort of all team members from LANXESS through to all the supplier organizations,” comments Mr. Dave Rogans, Director of PPTech.
Lanxess is a leading global producer of specialty chemicals. The Lanxess Newcastle plant is the world’s most modern chrome chemicals plant and employs advanced technologies in the production of sodium dichromate used in the production of leather tanning products to minimize raw material input and waste streams. At the same time, it is the world’s only facility for the electrolytic production of chromic acid that generates neither liquid nor solid waste products.
