Flexible distillate treating for demanding purity standards at low operating cost

The PETRECO METERCELL distillate treater removes a wide array of contaminants from hydrocarbon distillates. The METERCELL treater's electrostatic precipitators are designed as hydrocarbon distillate treaters and can be used for dehydration, strong or weak caustic treating, acid treating, and waterwashing of hydrocarbon streams. The METERCELL treater is often used for distillate dehazing or to lessen organic acid content, thereby reducing the total acid number of the distillate product using a caustic wash.

The METERCELL treater is the culmination of nearly 100 years of evolution and research, engineered to accommodate flexible processes and demanding purity standards (<10 ppm of water after treatment) while delivering performance with a resilient and efficient design.

The culmination of nearly 100 years of evolution and research, the METERCELL distillate treater is engineered with flexible processes and demanding purity standards in mind.
