Compressor Capabilities and Rebuilds

This compressor operates as a double-acting compressor, compressing gas during both the upward and downward strokes. It is a 2-stage compressor for loading and unloading railcars, offering an off-load capacity of around 500 GPM when both liquid lines are connected. One significant advantage of this compressor is its indifference to net positive suction head (NPSH), a factor known to cause complications for pumps. NPSH is a limitation in pump systems, in that low NPSH leads to high maintenance demands. However, with the Corken T791 LPG Compressor, NPSH becomes a non-issue. This makes it exceptionally well-suited for low NPSH applications, as it can handle them effortlessly, simplifying the transfer process.

This specific compressor is able to pull the pressure down in the rail car close to 0 psig, going from 170 psig to 0 psig. The compressor works by extracting vapor pressure from storage, compressing it, and then putting it on the rail car, effectively pushing the liquid out. Through a four-way valve system, the compressor can also recover vapors from the railcar and return them to storage, creating a closed-loop system. This design not only enhances efficiency but also ensures reliability and safety. Instead of only using pumps for LPG transfer, consider using a compressor. By doing so, you can potentially reduce maintenance costs and streamline operations. It's an efficient, reliable, and cost-saving choice for your industrial needs.
