CJSC Neftech has developed and patented unique high technology solutions and techniques of deep dehydration and desalting of oil using electrical fields at all stages of the process. Our know-how allows:

•  To increase the oil dehydration and desalting depth;
•  To reduce the energy costs
•  To save on flushing water and demulsifying agents;
•  To reduce the time necessary for breaking the emulsions.

CJSC Neftech innovations are also applicable to various refinery processes.
