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 liquefier units to produce large quantities of liquid nitrogen and liquid oxygen for in-plant use and for bulk liquid products distribution. UIG merchant liquid products plants and "piggyback" air separation and bulk liquid production plants can produce gas and liquid nitrogen and oxygen at any specified combination of production rates by integrating appropriately sized air separation and liquid production (liquefier) modules. |

Non-cryogenic Oxygen and Nitrogen Gas Production Units: Non-cryogenic product generators produce gaseous nitrogen or oxygen at near-ambient temperature. They can be a cost effective choice for relatively small-consumption rate gas users; in particular, those which do not require highly purified "liquid grade" product. Pressure swing adsorption (PSA) and membrane nitrogen production units typically make nitrogen at purities between 95 to 99.5%. Non-cryogenic oxygen plants produce product at about 90 to 93% purity and, like non-cryogenic nitrogen units, are normally most cost-effective at relatively low usage rates. Air Compression and Drying Systems: Compressed Dry Air Supply Systems can be supplied as stand alone systems or integrated with the front end of air separation plants.

Oxygen Plants,
Nitrogen Plants, Air Separation Plants and Liquefiers The UIG cryogenic air separation plant sales and services group designs, manufactures, sells and installs cryogenic oxygen plants, cryogenic nitrogen plants, and multi-product cryogenic air separation plants. Air separation units co-produce nitrogen, oxygen and argon. These versatile units are used to produce gases for on-site supply applications and, in conjunction with a liquefier unit, to produce liquid nitrogen and liquid oxygen or distribution as bulk liquid products. Cryogenic air separation units (ASUs), cryogenic nitrogen plants and cryogenic oxygen plants usually have the ability to produce a small percentage of the total plant product as liquid oxygen or liquid nitrogen. This capability can be useful for maintaining or rebuilding backup liquid inventories. If a plant will be located in a relatively remote area, process conditions can be optimized around maximizing production of backup liquid. When large volumes of liquid are required to support customer operations and / or bulk merchant liquid product sales, the air separation unit can be coupled with a liquefier. Liquefier units provide large amounts of very low temperature refrigeration, allowing some or all of the available nitrogen, oxygen and argon to be sent to storage as liquefied industrial gas products. Liquefiers can be supplied and configured as stand-alone units (which allows maximum operating flexibility for "piggyback" gas and liquid plants) or they may be fully integrated with the ASU - providing all of the refrigeration required for air separation and product liquefaction. Combining the ASU and Liquefier refrigeration generation equipment can minimize the capital cost for plants which will primarily or exclusively produce bulk liquid products (liquid nitrogen, oxygen and argon). |

Every Industrial Gas User and Plant Site is Unique | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
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. |

Different Types of Plants for Different Customer Requirements | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Conventional cryogenic air separation plants (and single product cryogenic
nitrogen and oxygen plants) separate and purify desired products at very
low temperatures, produced through a combination of compression, heat exchange, and expansion of a portion of the process gas
to remove energy. Conventional air separation cycles are the most efficient way to produce large
quantities of very pure products at relatively constant production rates.
When demand is not constant, when demand is relatively low, and /or when the end use does not require high purity product, alternative production cycles and processes may be a better choice. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
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 be one of the following alternatives:
Oxygen Production Alternatives: In addition to high purity cryogenic oxygen plants, UIG can provide several alternatives when lesser product purity is acceptable.

UIG Optimizes Overall Supply Systems | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
System optimization does not stop with
specification of the air separation plant, or nitrogen or oxygen
production unit. A fully-optimal facility design will reflect all aspects of
anticipated operating conditions at the site. UIG strives to provide
plant supply solutions which represent the best combination of cost and
performance, as determined by customer priorities and criteria.
UIG develops complete plant designs which integrate the air separation unit (and, if included, the liquefaction system) 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 provides well-optimized systems, providing operational flexibility, high operating reliability, and cost-effective operation. |
