Demulsifier

Description

 Demulsifier

Products
This series of products are high polymers polymerized initiator including polyamine, propylene glycol, stearyl alcohol, and resin with PO and EO. Some of the products are polymerized in crosslinking with epoxy chloropropane or isocyanate or in auto-polymerizing of unsaturated substances.

DESHI CHEM provides a wide range of demulsifer formulations for tough oilfield emulsion problems. We have developed more than *0 kinds of demulsifers to meet the requirements of different situations. The catalog does not list all the demulsifier products.

There are two major categories of demulsifiers, oil soluble and water soluble. Oil soluble product is a perfect blending of polymer compounds polyamines, propylene glycol, octadecadienoic alcohol, and propylene oxide, ethylene oxide in aromatic solvent. It is intended to effectively separate formation water from emulsion in crude oil. Water soluble product uses water as the solvent and it is intended to effectively separate oil from treated water.

Answer to some common questions

1.    Will higher treating temperatures always give better oil/water separation?

Not always. Higher temperatures usually help, but in some cases particularly where very light oils or condensates carry waxes additional heat has been seen to give negative results.

2.    Will demulsifier treatment interfere with bactericide, scale inhibitor, or corrosion inhibitor treatments?

Only in extremely rare cases.

3.    Once the proper dumulsifier is found for a given crude, can I expect it to work for the life of the production?

In some cases, the same formulation has been effective for tens of years. There exist those miserable systems, however, which change so frequently that the dumulsifier may have to be reevaluated every few days to weeks. These are normally new wells, and they may clean up after producing for some months.

4.    What is the single most common reason that a demulsifier stops functioning in a system?

Chemical injection has been interrupted, or has dropped below the minimum effective treating level. The reasons include gas locking of chemical pumps, plugged filters, loss of power to chemical pump, plugged injection lines, leaking check valves, an- in some parts of the world- sabotage.
