UIG Designs, Manufactures and Supplies Cryogenic Air Separation Plants: 

Universal Industrial Gases designs, manufactures and constructs multi-product cryogenic Air Separation Units (ASU) producing nitrogen, high-purity oxygen and argon. UIG is also a manufacturer and supplier of single-product cryogenic oxygen  plants and cryogenic nitrogen plants. 

UIG air separation plants, nitrogen gas plants and oxygen gas plants can be supplied with stand-alone or fully integrated liquefiers to manufacture liquefied industrial gas products for bulk liquid distribution and in-house use. 

UIG merchant liquid products plants and "piggyback" gas and liquid product plants can produce nitrogen and oxygen at any specified combination of production rates through integration of appropriately sized air separation and liquefier units. 

UIG Supplies Non-cryogenic Nitrogen Gas Plants:

Non-cryogenic product generators produce gaseous nitrogen at near-ambient temperature and cost-effectively meet the needs of many smaller-volume users; in particular, users which do not require "liquid nitrogen-grade" product. Pressure swing adsorption (PSA) nitrogen plants can cost-effectively produce 95 to 99.5% oxygen-free nitrogen product at rates up to about 40,000 scfh (1000 Nm³/h). 

UIG Supplies Carbon Dioxide Recovery and Liquefaction Plants:

Carbon Dioxide Plants recover, purify and liquefy carbon dioxide from CO₂-rich feed gas streams. Typical applications recover byproduct CO₂ from ammonia plants and ethanol plants to produce "food grade" or "industrial grade" liquid product. 

The UIG cryogenic air separation plant sales and services group designs, manufactures, sells and installs cryogenic oxygen plants, nitrogen plants, and multi-product cryogenic air separation plants.  Air separation units co-produce nitrogen, oxygen and argon. 

Under most operating conditions, air separation units (ASUs), cryogenic nitrogen plants and cryogenic oxygen plants can produce a small percentage of product as liquid oxygen or liquid nitrogen.  When large volumes of liquid are required to support customer operations or bulk merchant liquid product sales, the air separation unit can be coupled with a liquefier to provide supplemental refrigeration to convert some or all of the available nitrogen, oxygen and argon to liquefied industrial gas products. Liquefiers can be supplied as stand-alone units, allowing maximum operating flexibility, which can be particularly useful for "piggyback" gas and liquid plants, or as part of a fully integrated ASU/ liquefier combination to realize capital cost savings for plants which will primarily or exclusively produce bulk liquid nitrogen, oxygen and argon products.

Defining the optimal industrial gas production and supply system for a particular application requires consideration of many variables.  These include the number of required products (nitrogen, or oxygen, or nitrogen plus oxygen and  argon), required product purities, desired range of production rates for gas supply and liquid production, required product delivery pressures, and additional considerations reflecting daily and long term variations in demand patterns and the cost of power at the site.

All gas and liquid supply systems manufactured and supplied by UIG are optimized to meet customer-specific site requirements for product purity, delivery pressure, and anticipated variations in demand for each product in a cost-effective and reliable manner.

Nitrogen Production Alternatives:  For sites which use only nitrogen, at rates below about 40,000 scfh (1000 Nm³/h) the most cost effective process choice may one of two alternatives to a conventional cryogenic nitrogen plant.  For users requiring high purity product, a LIN-assist plant may be the best choice.  When , when product purities in the range of 95 to 99.5% are acceptable, a nitrogen PSA plant may offer the lowest cost product. Both of these types of plants also offer advantages when product usage will be intermittent.

Carbon Dioxide Recovery and Liquefaction:  UIG provides equipment for recovering, purifying and liquefying carbon dioxide from ammonia plants, ethanol plants, and other CO₂ sources.

As appropriate for the specific site and operating conditions, the plant will integrate the air separation (and liquefaction) unit with appropriately configured and sized auxiliary equipment such as pipeline compressors, liquid storage tanks for backup and supplementation of plant production, liquid vaporizers (ambient and, where needed, heated), elevated pressure gas storage, and bulk merchant liquid products storage and trailer loading systems.

UIG all-new air separation plants, industrial oxygen plants and nitrogen plants combine competitive first cost and operating cost with efficient packaging to minimize field work, superior operating characteristics, and advanced control and monitoring systems that allow unattended operation and remote monitoring and control. 

You can rely upon UIG to provide a total product supply system that is complete, robust, and cost-effective; and designed to best meet your current, and expected future, operating conditions. 

UIG Field Services: Installation, Commissioning, and Customer Support

The UIG air separation equipment and services supply scope is determined by customer needs and preferences. New plants can be purchased FOB manufacturing sites - or with UIG installation, commissioning and other services - up to full turkey installation, commissioning, technical training and ongoing support services. 

Contact UIG with your needs. 

We will review your particular circumstances and suggest air separation plant solutions that provide the right mix of technology, plant capacity, auxiliary equipment and services.  If you currently are under contract with an onsite gas supplier and/ or liquid supplier, please see our tips on changing your industrial gas supply system and supplier.
