Marine Exhaust Gas Scrubbers

Corrosion Technical Series

Corrosion in Marine Exhaust Gas Cleaning Systems (Scrubbers)

April 13-14, 2021
9 a.m. - 1 p.m. CST each day (Lectures followed by Q&A)
Virtual (Zoom)

This two-day virtual short course focuses on guidance and current discussion of materials selection and corrosion of marine exhaust gas cleaning systems (EGCS or scrubbers). The marine industry is facing the challenge of adopting new technologies and/or operational practices to comply with stricter international, regional, national and local regulations introduced to reduce air emissions from ships. The adverse effects of exhaust gas emissions from internal combustion engines and boiler exhaust gases on human beings and sensitive ecosystems have been well documented by the scientific community.

Critical amongst these regulations are the measures to reduce sulfur oxide (SOx) emissions inherent to the relatively high sulfur content of marine fuels. Ship designers, owners and operators have a number of different routes to achieve SOx regulatory compliance:

  • Use low-sulfur marine fuels in existing machinery
  • Install new machinery (or convert existing machinery where possible) designed to operate on a low sulfur alternative fuel, such as liquefied natural gas (LNG)
  • Install an Exhaust Gas Cleaning System (EGCS) as an after-treatment device
