Problem solving
We offer a complete range of products and services for filtration, but above all the advice and technical assistance necessary to identify the most advantageous treatments for our customers, because they can improve the performance of the machines and, thanks to the programming of maintenance plans, hoc, help prevent breakdowns and arrests in production. La Ricambi Udinese offers hydraulic advice on filtration and similar, retrofitting sizing on filtration in pre-existing hydraulic systems.
PROBLEM SOLVING: COGENERATING PLANTS
The problem
Our costumer needs were to have an affordable and long lasting system that could guarantee a percentage as low as possible of H2S in the incoming side of the engine.
The cause
Cogenerating plants, require an accurate maintenance. Part of this maintenance regards the lubricating oil change. This oil has to be changed since it becomes quickly polluted from acids as Hydrogen Sulfide and from Hydrogen Chloride. This acids becomes from the binding of water contained in air and Sulfuric Acid (H2S) and Chlorine (Cl), contained in methane obtained respectively from the fermentation of animal wastes or from rubbish dumps. This acids, once dispersed in lubricating oil, intake the inner engine parts, creating serious corrosion damages. Due to what written, lubricating oils must be changed frequently to maintain as low as possible the acid concentration. A customer of us, utilizer of a cogenerating system supplied by methane obtained by animal waste fermentation, had the problem of a very high intake percentage of H2S and asked us for a system to lower this percentage.
The solution
After some valuations and an accurate survey of the system, we supplied a filtration system based on Activated Carbons, special made for this kind of application.
The effect of this carbons, together with the special designed container, brought the H2S percentage to 661PPM (parts per million) to 0 (this level has been successively upgraded to 95 PPM from the customer, to not overload the activated carbon system). As a result, our customer has lengthened the interval between oil changes, decreasing maintenance costs and direct costs due to the oil change and the used oil dispatch, beside less maintenance operations that are required.
