Considerations In Choosing The Right Wax And Asphaltene Solvent

By Maria King


The importance of oil and petroleum in this increasingly industrial and technological world cannot be overstated enough. Newer and better technologies have been devised and created so as to vamp up the mechanisms and other ways and means in oil production. Quality yields are still an issue, however. With this regard in particular, answers have been pitched with the Wax and Asphaltene Solvent.

There are many problems and issues prevalent and singular in the petrochemical industry. One premium consideration industrial engineers will be able to discourse with a vengeances is the buildup of paraffin wax and apshaltene. Given the natural state and composition of oil, it is a little wonder how most of the worlds supply is prone to the contamination of these precipitates.

First off, it would do to pursue avoidant courses of action. For example, the company might try to rule out areas and conditions inside the so called asphaltene precipitation envelope. This given area is by itself the turf of the formation of these precipitates. However, this measure is not always effective and feasible. This is because of drawdown near the wellbore, which affects the onset pressure of reservoirs.

One such innovation is the gravimetric technique, which uses a conventional PVT cell. There is also acoustic resonance, light scattering, and the flirtation technique, the last of those utilizes a hydrophobic filter during a depressurization test. Theres also electrical conductance. Another is the viscometric technique. This fancy sounding method merely looks and tracks changes in viscosity curves of the petrochemical, which is pretty much intuitive by itself, since precipitate enriched oil is inherently thicker and more viscous.

In this regard, it would do to be sagacious and introspective in the technique one means to use because they are many and sundry. One should also opt for the method that is less damaging. You might want to settle on something that is not only guaranteed as effective, but one that provides thorough cleaning and minimal damage to the reservoir.

Many methods can be used to remove the buildup of paraffin and asphaltene. The ways may range from manual scraping or coiled tubing, to mechanical means. Thermal techniques, like hot oiling and hot water. And then there are also the chemical methods, as in using dispersants or wax solvents. Sometimes, a single ways and means is not at all sufficient by itself and combination treatments are necessary.

The method used is not at all based on cursory criteria, like it being the whim of engineers or contractors. Rather, trusty elements are considered. The most evident of which is, of course, the nature of the buildups. Also, it would do to go all out in this enterprise. When there has been an accumulation of deposits, the actuality is that there is fouling involved, as well.

One would also do well to appreciate the scope of a given problem. For example, wax and asphaltene are usually not the only components in the deposits. The two may even amalgamate, causing it to have upped and stronger properties. These heavy organic deposits may also be a composite of silt, gums, resins, sand, scale, clay, and salt crystals. All of which greatly undermine the quality of petroleum. Therefore, the solvent used should be thorough and all out, removing these aforementioned substances as well as it does paraffin.

When looking for the right kind of solvent, see to it that it is environmentally friendly. More practicably, establish that it has an enhanced emulsion system. It should thoroughly dissolve asphaltene and wax formation and deposits. Moreover, it should be longer lasting, with a great record of safety and environmental footprint. You cant go wrong with these criteria.
