In this paper, the chemical exergy in waxy crude oil pipeline transportation process was mainly calculated and studied. On the one hand, the specific chemical reaction exergy of waxy crude oil in oilfield was derived according to the common…
• Sonochemical technique has the best effect for crude oil demulsification/dehydration. • The influence factor for sonochemical demulsification/dehydration is investigated. • Recent progress on ultrasonic demulsification equipment is introduced.…
In this work, the effects of four different chemical inhibitors, namely a polymeric surfactant, synthesized -Al2O3/NiO nanoparticles, epoxy resin, and canola oil to inhibit asphaltene precipitation in three different crude oils collected from various…
As waxy crude oil comes to the surface, it will cool down and causing the waxy fraction to gel. The gelled crude chokes the well, leading to restricted or blocked production and costly downtime for operators. One of the most common chemical solutions…
Deposition in natural gas pipelines is an issue of enormous economic and security consequences. In the past, corrosion products, elemental sulfur, hydrates and sand were common deposits in these pipelines. This study demonstrates for the first time…
Production from highly paraffinic crude oil wells poses unique technical challenges such as poor flowability and paraffin deposition on the production tubing. Paraffin deposition increases the lift load on the pump, reduces pump efficiency, and…
