Oil based drilling waste harmless treatment & safety disposal --- Add chemical

By: GN Solids America
HOUSTON - May 20, 2015 - PRLog -- Since oil developing is now more difficult than before, more oil based mud are used for drilling; then there comes more oil based cuttings, which is harmful to the environment. While most of the countries have very strict oil based cuttings disposal. The requirement is vary in different countries, normally OOC should less than 5%, and developed countries will require less than 1%.

GN vertical cuttings dryer (http://www.gnsolidsamerica.com/vertical-cuttings-dryer.html) lower the OOC down to 3~5%, for some oil based cuttings, before going to the cuttings dryer, need treated by chemicals, surface active surfactant, to separate the mixtures to three layers, oil, water, cuttings, then oil can be reused, the chemical in water is harmless, so also can be recycled, cuttings can achieve 3%, or lower, which depends, and can be discharged

Treating oil-contaminated waste can be a real… treat! And with continuously changing waste streams the ‘perfect solution’ can be difficult to find.

We regularly have people contacting us to ask what the most efficient process is to treat oil-contaminated waste. With oil waste, as I am sure you know, there is no “one size fits all’ but we have experienced some very effective processes in our time. Let me share a little of that experience with you by walking you through one process we have seen work very effectively in the past:

Pump the waste from your storage tank (http://www.gnsolidsamerica.com/mud-tank.html) to the centrifuge input feed just before it enters the feed use a static inline mixer to mix the chemical with the sludge you can use a range of chemicals to aid the separation process (this could be anything from demulsified to polymer or SAS Micro emulsion products)

The mixture is then fed through the centrifuge.

The solids separate from the liquid and fall out the bottom of the centrifuge (https://en.wikipedia.org/wiki/Decanter_Centrifuge).

The liquid, which will contain oil, water and some chemical, is then pumped to a settling tank.

Here the water and oil separate under gravity, a process which is accelerated and enhanced by the SAS chemicals.

Now SAS is partnering with GN Solids Control (http://www.gnsolidsamerica.com/contact.html) for a whole solution.
