Abstract
The present invention relates to the reduction of harmful exhaust emissions on ships using diesel engines equipped with a wet emissions reduction system. In particular, the invention relates to a large diesel internal combustion engines installed on a ship and fitted with a wet emissions reductions system that is supplied water by an onboard advanced wastewater treatment system (AWTS).
Claims14
A system comprising:
- an AWTS clean effluent tank;
- a primary sensor, primary pump, and primary control system;
- an additional filtration system;
- a secondary sensor, secondary pump, and secondary control system;
- a wet emissions technology reserve tank;
- and
- a tertiary sensor, tertiary pump, and tertiary control system;
- wherein said system is adapted to be connected to a wet emissions reduction system on one or more diesel engines on a ship;
- wherein said AWTS clean effluent tank is connected via pipes that carry AWTS clean effluent from said AWTS clean effluent tank to said primary sensor, primary pump, and primary control system;
- wherein said primary sensor, primary pump, and primary control system is connected via pipes that carry AWTS clean effluent from the primary sensor, primary pump, and primary control system to said additional filtration system;
- wherein said primary sensor, primary pump, and primary control system is connected via pipes that carry AWTS clean effluent from the primary sensor, primary pump, and primary control system to said wet emissions technology reserve tank;
- wherein said additional filtration system is connected via pipes that carry filtered AWTS clean effluent from said additional filtration system to said secondary sensor, secondary pump, and secondary control system;
- wherein said secondary sensor, secondary pump, and secondary control system is connected via pipes that carry filtered AWTS clean effluent from said secondary sensor, secondary pump, and secondary control system to said wet emissions technology reserve tank;
- wherein said secondary sensor, secondary pump, and secondary control system is also connected via pipes that carry rejected/recirculated filtered AWTS clean effluent from said secondary sensor, secondary pump, and secondary control system to said primary sensor, primary pump, and primary control system;
- wherein said secondary sensor, secondary pump, and secondary control system is also connected via pipes that carry rejected/recirculated filtered AWTS clean effluent from said secondary sensor, secondary pump, and secondary control system to said additional filtration system;
- wherein said wet emissions technology reserve tank is connected via pipes that carry filtered AWTS clean effluent from said wet emissions technology reserve tank to said tertiary sensor, tertiary pump, and tertiary control system;
- and
- wherein said tertiary sensor, tertiary pump, and tertiary control system is connected via pipes that carry filtered AWTS clean effluent from said tertiary sensor, tertiary pump, and tertiary control system to said wet emissions reduction system.
