What To Look For In A Wax And Asphaltene Solvent

By Maria King


The petrochemical industry is an important one, and more so in this modern day and age. Everything from cars to colossal industrial machinery and equipment relies on the trusty black gold for its function. However, this industry is more complex and convoluted than any workaday person thinks. Even on top of the risky and perilous retrieval of petroleum, it is also important to make sure that these substances are well up to the required standards. If they are not, the site manager might want to think about using Wax and Asphaltene Solvent.

These two common precipitates are actuated by quite a wide array of factors. These may include changes in temperature, pressure, and the composition of the contents inside the wellbore. It may be remarked upon that these aforementioned factors are not at all uncommon and strange, so it follows that deposit formation is not quite a far cry from commonly happening.

This occurrence greatly devalues the quality of petrochemicals. Potentially, it can also make the site dysfunctional and unusable for future use. These paraffin deposits reduce oil flow, affecting the product itself, and the accumulation in the wellbore may lead the cessation of production altogether.

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.

With some products, however, production restoration and treatment lasts longer than is accustomed with toluene and xylene. Some take up to six months to nearly one year. Some innovations include the use of polymeric dispersants and de asphaltened oil, or just about any other substances with native resin and aromatic contents. Some really promising products are well enough as far as everything is concerned. However, they also cannot be available economically.

Precipitation and consequent deposition is detrimental in the petroleum industry. The organic sludge may clog pipelines, tubes, down holes, and the whole reservoir facility in general. Therefore, one should consult the solvent experts before this solvable problem can grow heftier by the day, and thereafter considerably affect oil production and distribution.
