As one of the famous solids control and waste management equipment manufacturers and turn-key solution provider, GN Solids Control has provided hundreds of customized solids and liquid separating systems, one of the most popular systems is GN Oil Sludge Treating System.
Last year, GN Oil Sludge Treating Systems were sold to USA, Kuwait, Qatar and Uganda etc.
In order for everyone has a better understanding, we’d like to pick up some of the questions our customers asked before:
On the Mixing Tank that feeds the second decanter centrifuge, we will want to add another 3 inch connection to the tank bottom to supply our Reactor. Another example, on the V-Bottom Tanks with screw conveyor, I will want to add an overflow weir to skim oil. This means that we will want to add some our Innovation custom design modifications. After we place the order, I would like to visit you in Houston and we would spend a day together marking up your standard design drawings with our needed modifications.
The piping connections between the mixing tanks and pumps, and pumps to decanters, are those hard steel pipes or are they flexible heavy duty hoses? Most of them are flexible hoses, not sure if they are heavy duty; few of them are hard steel pipes.
The Vacuum Transfer Pump is very impressive but 17 cubic meters per minute high pressure air consumption is too much and too expensive for this small system design. I am thinking of adding another Wilden T4 AODD pump. I don't like that the Wilden T4 pump only passes < 5mm solids. Do you have a better suggestion for the first pump to feed the Pre-Mixing Tank?
As you mentioned the solids content is around 30%, which is very hard to transfer by the other types pumps, only vacuum pump can transfer the high density and large viscosity oil sludge. However, screw conveyor might be used, but you will use one excavator to fill into a catching box of the conveyor. Obviously it's not the best option.
We will add the 20 foot Electrical Distribution Center to our system. I assume all piping connections on the various tanks will include valves? Do you use butterfly or knife gate valves? Yes, we use butterfly valves. If you have particular demands, we can modify our system. GN is especially good at providing tailored oil sludge treating system.
