Universal Industrial Gases, Inc: Cryogenic Air Separation Plant Manufacturer, Supplier, Builder - Nitrogen Plants, Oxygen Plants, Liquefiers

Cryogenic Air Separation Plants and Liquid Plants
Producing Nitrogen, Oxygen and Argon

Universal Industrial Gases is a designer, manufacturer, supplier and installer of cryogenic air separation plants producing high purity nitrogen, oxygen and argon. In addition to multi-product air separation units, single-product cryogenic oxygen plants and cryogenic nitrogen plants are also available.

UIG air separation plants, nitrogen production plants and oxygen production plants can be linked with stand-alone or fully integrated liquefiers to produce liquid nitrogen and liquid oxygen for distribution as bulk merchant liquids or for in-house use.

UIG merchant liquid products plants and "piggyback" gas and liquid product plants can be designed and built to produce nitrogen and oxygen at virtually any specified combination of gas and liquid production rates through integration of an appropriately sized air separation unit and one or more liquefier units.

UIG designs and constructs oxygen plants, nitrogen plants, air separation plants and liquefiers

UIG Cryogenic Air Separation Plants and Liquefiers - Standards and Options:

UIG plants are designed for minimal operator supervision. Plants include automated process optimization, remote monitoring and control capabilities, provisions for automatic call-out of support personnel when out of range conditions are encountered, automatic shutdown if potentially unsafe conditions are detected, and automatic activation of backup liquid vaporization systems to maintain continuity of pipeline product deliveries.
UIG air separation plants and cryogenic oxygen plants utilize energy efficient dual column technology.
UIG cryogenic nitrogen plants may employ single-column technology to produce nitrogen gas at common distribution pressures without a product compressor.
LOX-boil and pumped-LOX cycles are available for oxygen gas production at elevated pressures without an oxygen compressor.
UIG air separation plants and cryogenic oxygen plants can be supplied with all-cryogenic argon recovery and purification systems.
Air separation units, cryogenic nitrogen plants and cryogenic oxygen plants can produce a small portion of total product as liquid to maintain the inventory of backup liquid.
When large volumes of liquid nitrogen or oxygen are required, a liquefier unit can be supplied to provide the necessary refrigeration.
"Stand-alone" ASU and liquefier combinations provide operators with the greatest amount of operational flexibility. This can be a particularly useful option for "piggyback" plants which will produce significant volumes of gas for on-site use.
Fully-integrated liquefier and air separation systems can also be supplied. This configuration can be the most cost effective choice when most, if not all, of the plant production will be in liquid form.

All gas and liquid supply systems are optimized to meet customer-specific site requirements in a cost-effective and reliable manner. Variables which impact design of the total supply system include:

The number of products required (nitrogen, or oxygen, or nitrogen plus oxygen and argon)
Required product purities
Required product delivery pressures
Desired range of production rates
Daily and long term variations in demand
Cost of electric power
