Recommendation for pumping wastes at gas conditioning plant 1

[bimr]

I have a project at a gas conditiong plant in eastern Europe. I am interested in a pump recommendation at a waste facility at a gas condition plant. At the present time, the waste material is being dumped into a sludge pond. We have plans to install alternative treatment facilities to clean up the waste stream and the site. The dissolved solids are so high that the treated liquid will be deep well injected. The flow averages about 8 m3/hr or so and the pump discharge pressure should be about 50 psi. Trucks deliver to the site and off load.

There are issues with equipment sourcing and importation, availablity of pump service, as well as the site being remote. The waste parameters are listed below for the worst case.

40000 mg/l suspended solids
4000 mg/l hardness
11000 mg/l oil
7 to 10 pH
20000 Suspended ash (50% FE, 20% Hardness, 45% Other/Grit)
7500 FE
400000 mg/l COD

The waste consistency can vary from truckload to truckload with the heaviest solids being generated from tank bottoms during the periodic annual shut downs. In short the consistency varies from an oily liquid to tank bottoms.

Is there any pump on the market that can meet these requirements? Does anyone have any experience with the wastes that have been described.

Looks like some rough stuff… a progressive cavity pump may be a good place to start.

A diaphragm pump can handle that and is not too expensive.

Do you which manufacturers are international and have service for these pumps? Most of these pumps seem to be air powered. Is electrical power an option?

 

[micalbrch]

I know that ABEL Pumps have electrically driven diaphragm pumps for low pressure applications, too. Milton Roy is another option but these are more metering pumps and I suppose you do not need a high accuracy.

I would check out peristaltic pumps. Long time since I was involved with them , the sludge shouldn't be a problem but not sure if you can get that flowrate.


It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

 

[micalbrch]

Another good idea. The flow rate is not a problem. Watson Marlow and Verder have those.

Thanks micalbrch for the Abel pump suggestion. The Abel pump looks like it will work and they have service here. Don't see how a peristaltic pump would work for this application.

 

[micalbrch]

Are you scared about the solid content? I don't see a problem for a peristaltic pump but I might be wrong.

 

[Artisi]

If you are considering the Abel pump as being suitable then the peristaltic should also be suitable, a lot less wearing parts with easy maintenance.
