CO2 Pumping Systems - Supercritical to Your Success.

When shopping for a supercritical CO2 extractor, the most important consideration is the pumping system of the extractor. This is the heart of the extractor which determines the rate and yield of oil that will be produced. Yet the pumping systems for CO2 extractors are plagued by design flaws and manufacturing mistakes. To make a wise investment in a CO2 extractor it is essential to understand the pumping system within the machine.

Evaluating Pumping Systems in CO2 Extraction

There are three basic pumping configurations used in CO2 extraction: liquid, gas booster, and dual- pumping. A liquid pump, pumps liquid CO2. A gas booster pumps gaseous CO2. In a dual-pump system, the liquid pump and gas booster are both used in the same extraction process. This article will explain how the three designs work and look at the pros and cons of both.
