Universal Industrial Gases, Inc: Industrial Gas Plant Manufacturer - Nitrogen and Oxygen Plants Supplier - New Air Separation Plant and Liquefier Manufacturers

Industrial Gas Plant Manufacturer / Supplier
Oxygen Plants, Nitrogen Plants, Air Separation Plants and Merchant Liquid Plants

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 produce large quantities of 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.

Manufacturers of new cryogenic air separation plants. ASU cold boxes house heat exchangers and cryogenic distillation system components operating at very cold temperatures.

UIG Supplies Non-cryogenic Gas Plants:

Non-cryogenic product generators produce gaseous nitrogen or oxygen at near-ambient temperature, and cost-effectively meet the needs of many smaller-volume users; in particular, users which do not require "liquid 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). Non-cryogenic oxygen plants produce product at about 93% purity and may be a good choice at lower production rates.

UIG Supplies Carbon Dioxide Recovery and Liquefaction Plants:

Carbon Dioxide Plants recover, purify and liquefy carbon dioxide from CO₂-rich feed gas streams produced as a byproduct by several types of plants, including ammonia plants and ethanol plants. UIG can supply equipment to produce "food grade" or "industrial grade" liquid product.

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, nitrogen plants, and multi-product cryogenic air separation plants. Air separation units co-produce nitrogen, oxygen and argon for on-site use or for liquefaction and distribution as bulk liquid products.

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 this capability is useful for maintaining or rebuilding backup liquid inventories, the plant can include provisions for collecting and transferring available liquid to a backup storage tank.

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. Liquefiers provide supplemental refrigeration which is used 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, which allows maximum operating flexibility, which can be particularly useful for "piggyback" gas and liquid plants, or they may be fully integrated with the ASU to provide an ASU/ liquefier combination to realize capital cost savings for plants which will primarily or exclusively produce bulk liquid products (liquid nitrogen, oxygen and argon).

UIG knows that 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.

UIG Offers Different Types of Plants for Different Types of Requirements

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.

Oxygen Production Alternatives: In addition to high purity cryogenic oxygen plants, UIG can provide several alternatives when lesser product purity is acceptable. If 95 to 96% purity is sufficient, low-purity cryogenic plants can be provided which will provide both capital and operating cost savings versus a high-purity (99.6%) oxygen plant. When even lower purities are acceptable (typically 92 to 93% purity) and, in particular, when demand is relatively low (under 50 tpd) non-cryogenic oxygen production can be considered. VPSA oxygen plants may be a good choice above about 30 tpd, while PSA oxygen production plants may be preferred at lower rates.

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

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.

What Type of New Plant Is Best for My Needs?

There are many types of air separation plants available - cryogenic, non-cryogenic, single product, multi-product, high-purity, lower-purity. Which type is the best choice for a given application depends on several factors, including the product purity requirement, supply pressure requirement, maximum flow rate needed, the cost of power at the site, whether usage is continuous or not, steady or not, etc.

Our page on Production / Supply System Optimization discusses how optimal technology choices typically change when selecting new plants to make nitrogen or oxygen gas, at various combinations of flow rate and required product purity.

Note that the boundaries between optimal application regions for different types of nitrogen gas and oxygen gas plants are neither sharp nor fixed. Selection of the best type of supply approach for a given application depends on many location and application-specific factors, including anticipated power cost, pressure required and usage pattern.

UIG will work with you to define the best choice of technology, plant capacity and specific equipment to meet your particular requirements and preferences.
