Methanol Auxiliary Engine: DOC + (DPF optional) + (SCR/ASC depending on regulations and vessel type) Methanol Main Engine (Two-Stroke / Four-Stroke): SCR (for NOx control) + DOC (for CO/HC/odor reduction) + ASC (for ammonia slip control) Methanol-fueled vessels face emission and odor issues including CO, HC (containing oxygenated hydrocarbons such as methanol and formaldehyde), PM/black smoke, and NOx under various operating conditions. The Methanol Aftertreatment System employs a modular combination of catalytic oxidation (DOC), particulate filtration (DPF, optional), selective catalytic reduction (SCR, on-demand), and ammonia slip control (ASC, optional) to meet regulatory requirements, improve exhaust cleanliness, and reduce odor and visible smoke. It is suitable for both newbuilding and retrofit applications. Methanol Aftertreatment System —— Emission Compliance: Synergistic control of CO/HC/NOx optimized for methanol-fueled operating conditions Odor & Aldehyde Risk Reduction: Enhanced oxidation conversion efficiency for oxygenated hydrocarbons and aldehydes (tailored catalyst formulation) Modular Adaptability: Flexible combination based on engine type, exhaust temperature window, space, and backpressure constraints Lifecycle Cost Control: Consumables, maintenance, and OPEX quantifiable for easy owner operational management Core Values —— Wide Temperature Window Catalytic Strategy: Adapts to exhaust temperature fluctuations under low/variable load conditions Low Backpressure Design: Meets main/auxiliary engine backpressure margin requirements (project-based calculation) Corrosion Resistance & Marine Adaptability: Engineered for materials, corrosion protection, vibration resistance, and maintenance access Online Monitoring & Control: Monitors temperature, differential pressure, NOx, etc., with optional IAS/AMS integration Safety Interlocks: Safety logic for overtemperature, overpressure, bypass, regeneration (e.g., DPF), etc. (configuration-dependent) System Features —— Typical Configurations (Examples): —— |
