Abstract
A neutralization processing system for an ammonia-containing waste fluid, includes: one or more sludge tanks; a sludge discharge line configured to supply the waste fluid to the sludge tank; a neutralizer supply line configured to supply a neutralizer to the sludge tank; and a sensor configured to measure pH of the waste fluid or an ammonia concentration of the waste fluid.
Claims14
A neutralization processing system for an ammonia-containing waste fluid, the neutralization processing system separating a waste fluid containing at least sludge and ammonia from lubricating oil after use in a ship diesel engine to neutralize the waste fluid, the neutralization processing system comprising:
- a purifier configured to purify the lubricating oil;
- a sludge tank;
- a sludge discharge line configured to supply the waste fluid separated from the lubricating oil by the purifier to the sludge tank;
- a neutralizer supply line configured to supply a neutralizer to the sludge tank;
- and
- a sensor configured to measure pH of the waste fluid or an ammonia concentration of the waste fluid.
