For crude oil dehydration, GlobeCore provides systems like the CMM-10 or customized oil treatment units adapted for petroleum applications. These systems use heating and vacuum technology to separate water and gases from crude oil. In practice, they are used in oil production and refining processes to improve product quality and prepare oil for further processing or transportation.

In practice, crude oil dehydration is rarely performed using a single method; instead, it typically involves a multi-stage process combining several physical effects. For example, before applying vacuum or thermal treatment, it is common to remove free water by means of separators (such as free water knockout units), since unbound water can be separated much more effectively at this stage. After that, the remaining emulsified water requires more advanced treatment — including heating, chemical demulsification, or vacuum processing.
In this context, heating and vacuum technology (as used in CMM-type machines) plays a key role, because heating reduces oil viscosity and promotes coalescence of water droplets, while vacuum conditions accelerate evaporation and removal of both dissolved and emulsified moisture.
At another point, process stability is critical: maintaining consistent temperature and flow conditions ensures efficient water removal and prevents the occurrence of issues such as foaming or incomplete dehydration in cases where the process is not properly controlled.
Therefore, while vacuum dehydration units serve as an effective solution, they deliver the best results when integrated into a properly designed process flow diagram that may include preliminary separation and process control stages.
If you’d like to obtain a clearer understanding of how dehydration systems are applied in practice and what configurations are typically used, I recommend taking a look at this article: https://globecore.com/oil-processing/transformer-oil-dehydration/.

You’re absolutely right — effective crude oil dehydration is a staged process that combines mechanical separation, heating, vacuum degassing and targeted polishing. In practice the most robust flow is to remove free (unbound) water first with separators/free-water knockouts, then reduce emulsified and dissolved moisture using thermal‑vacuum dehydration and coalescing/filtration. Systems based on vacuum dehydration and degassing with heating (CMM‑series) are the core of that second stage because heating lowers viscosity and promotes droplet coalescence while vacuum accelerates evaporation of dissolved and emulsified water; models such as CMM‑LT (thermal vacuum), CMM‑CF (coalescing filter front end), CMM‑1.0CF or larger LT/CF variants are commonly used depending on throughput. For very high initial water loads a coalescing stage ahead of the vacuum unit improves efficiency, and for ultra‑low residual moisture a zeolite adsorption polishing stage (CP‑130/CP‑260 with regenerable cartridges) can be added; a UVD vacuum filling unit is useful for controlled top‑up or small‑volume work.

Process stability and instrumentation matter as much as the hardware. Maintain steady temperature, controlled flow and target vacuum to avoid foaming, incomplete separation or re‑emulsification; preheating to an appropriate temperature for the crude lowers viscosity but avoid excessive heat that could affect product quality. Monitor water content with appropriate tests (centrifuge/visual for free water, Karl Fischer for dissolved water) and control chemical demulsifier dosing if needed to break stubborn emulsions. A properly designed skid—knockout separator → coalescer/filters → thermal vacuum CMM unit → optional zeolite polishing—with sampling points and control loops will give consistent dehydration to meet downstream specs (pipeline/export/refinery), and we can help size/configure the right combination for your feed rates and target moisture levels.
