MIST Oil Sludge Treatment - The Origins Story

Posted by Mark Zwinderman on 11-Jan-2018 12:00:00

January is MIST month at SASES. No better time to go back in time and see how it all started. We have now treated over 60,000 tons of crude oil sludge and slops at the Grangemouth refinery and recovered over 12,000 tons of high quality crude oil. Somewhere over 80,000bbl of crude recovered over a 10 year period. How did we do it?

Oil Waste Treatment - getting better results

Posted by Mark Zwinderman on 03-Feb-2016 09:58:31

Objectives

It is important to identify your waste treatment objectives at the start of your process. Understanding what you need from your waste process should be the first step to success. This could be: oil with less than 4% water, reduced waste to landfill by 50%, water clean enough for re-use, increased oil recovery etc.

If you are not achieving your ultimate goal it is important to evaluate your process in detail to identify where improvements can be made. If you are achieving your goals it could be beneficial to evaluate your process to assess if there is potential to improve further or achieve better-cost savings.

It can also be useful to look at any historical records that clearly show the data and how often the needed results were achieved. You can then assess what the circumstances were when these results were achieved.

Decanter Centrifuge

We often see decanters that have not been serviced regularly and in many cases the fact that results are less than optimum are down to basic issues with the decanter. Often the decanter has been used for different waste in the past and the settings are not optimized, this is not always difficult to solve and can make a huge difference to your results.

It may sound like an obvious thing to have to check but we have seen this quite a few times when the scroll is running the wrong way inside the centrifuge. Again easily fixed once spotted but will cause a whole range of issues if it is not resolved.

A scroll that is worn down or damaged will affect the size and shape of the beach inside the decanter and the movement of the solids within the equipment. Regular maintenance can detect and prevent this. Protection of the scroll through tungsten carbide protection is one option to reduce scroll damage.

Often the people that were trained to use the decanter have moved on in the organization or left altogether. The new individuals responsible have not always been through decanter operation and maintenance training. Even 1 or 2 days of basic training can have a measurable impact on the process

Cleaning of the interior of the decanter at regular intervals will prevent blocking the equipment and keep performance levels high.

Often decanters are set once for a type of waste and left in that configuration. The waste you are treating today might be quite different from the waste that was treated when the decanter was set up. A few basic changes in the decanter settingscan have a big impact on the outcome of the process.
