Process Technologies to Take Your Industrial Gas Plant to New Heightst

PGTI specializes in providing proposal generation and process design for new gas plants. We’ve developed new process technologies to enhance the profitability of your industrial gas business. I can create a process you may want to explore and determine that new cycle’s economic viability. Read below to learn more about our innovative process cycle designs: (NOTE: Some of these listed processes aren’t in the industrial gas business.)

A new air separation plant cycle that produces up to approximately 15 percent liquid product from an over-the-fence oxygen gas plant has been developed. This cycle doesn’t require a liquefaction cold box, which saves capital. It can be used for oxygen generators, but it’s especially advantageous for large oxygen plants in remote locations. The liquid oxygen, nitrogen, and argon produced in this piggyback plant can also be used to supply the merchant market. Argon production is also enhanced by this new cycle.
A variation of the cycle above is available for nitrogen generators and nitrogen plants.
A “combination” plant has been developed that produces LNG with liquid nitrogen, oxygen, and argon. This process cycle uses a common liquefaction facility, which saves capital compared to two independent, standalone LNG and merchant liquid plants. (For your reference, see US patent application number 14/265,535.)
Another combination plant process cycle utilizing a biofuel feed source can produce food-grade liquid carbon dioxide and LNG in a common facility.
High-pressure oxygen at 1800 PSIG or higher is now available with PGTI’s new process technology. This process increases the possible pressure levels for oxygen gas products.
Food-grade liquid carbon dioxide product is now possible from a biofuel feed source.
Helium recovery from an overhead nitrogen stream exiting a nitrogen recovery unit with a low helium concentration can be achieved economically.
Nitrogen-rich vented waste streams can be used to make nitrogen gas and/or liquid nitrogen products.
Power generation is possible utilizing a vented low-pressure, warm-temperature, and steam-rich vent stream.
Argon recovery from an argon-rich waste stream can be explored.
Ice production, refrigerated warehouses, and electrical generation can be executed by using the refrigeration available in pipeline pressure letdown stations.
