UCG On-site Supply of Nitrogen, Oxygen and Argon
Universal Cryo Gas produces nitrogen and oxygen for industrial gas users under cost-effective, long-term, utility-like onsite gas supply contracts.
UCG gas supply arrangements combine UIG equipment supply and installation with ongoing operations and maintenance by Universal Cryo Gas.
UCG on-site nitrogen and / or oxygen generation customers not only realize immediate cost savings versus alternative supply arrangements, but will see those savings increase as delivered costs for bulk liquid products rise.
|How Can Switching to an On-site Nitrogen or Oxygen Gas Supply Save Money?|
|When you purchase bulk liquid oxygen or
nitrogen products, you pay the costs associated
with separating air and producing purified products plus many other costs
which are avoided with an onsite gas supply. While you do not see these additional costs as line items in your invoices, they are,
Someone (ultimately, you) must pay for these costs associated with purchasing gases as liquids:
When you consider all the costs, inefficiencies and losses that are avoided when you arrange to have the products you need made at your site as gases, for immediate in-plant pipeline delivery to your usage points, it is not hard to see why you can realize significant savings with UCG on-site production and pipeline distribution arrangements.
Switching from vaporized liquid to on-site gas generation normally does not eliminate the need for a liquid storage and vaporization system. Liquid vaporization may continue to be used to supplement on-site gas production when demand suddenly increases, and during plant maintenance shutdowns. However, with a gas production plant on your site, the amount of liquid consumed to back up or supplement on site gas production will be only a small fraction of the volume which would have to be purchased if vaporized liquid was used to meet the entire demand for nitrogen or oxygen.
|When Will On-site Generation of Nitrogen / Oxygen be the Most Attractive Supply Option?|
The higher your average hourly demand, and the more constant your demand level, the more likely it is that on onsite gas supply can save you a significant amount of money.
Here are some quick Guidelines for determining how likely it is that you can benefit from switching to, or starting out with, on-site gas production:
Are you confused
about weight and volume measurement units?
A handy rule of thumb for quick estimating, is that, in North America, a full load for most liquid nitrogen and liquid oxygen delivery trailers is about 20 tons of product. This is equivalent to about 530,000 scf of gaseous oxygen or 610,000 scf of gaseous nitrogen..
|How Much Will I Save if I Switch to an Onsite Nitrogen or Oxygen Gas Supply?|
Savings are generally at least 20% (compared to liquid) and can be more than 50%. Savings are usually measured in hundreds of thousands of dollars a year.
No one can tell you exactly how much you might save until they fully understand your needs, have defined the system required to meet those needs, and can compare the before and after costs on a comparable basis. However, UCG can provide a preliminary estimate for the cost of onsite product once we know the type of product you need (including required purity and delivery pressure), your estimated average usage rate, and an estimated cost for power at your site.
Development of a definitive onsite gas supply proposal requires detailed information about your specific situation, including site conditions, the length of the supply period that you need or want, applicable electric power cost or rate schedules, and details of your anticipated usage pattern, including flow rate variations that occur on a daily basis or on a longer basis such as weekly, monthly, or seasonally. Recurring peaks can be handled cost effectively if they are identified up-front and incorporated into the sizing of plant components and operating strategies.
In general, onsite gas production savings will be higher the greater your average usage rate, the less variation in demand that you have each day and over more extended periods of time, the longer the agreed supply period, the lower the cost of electric power at your site, and, since the assumed comparison is against the cost of using bulk liquid products, the greater the cost for delivered liquid product.
Keep in mind that only a portion of your onsite gas costs will escalate over time - and only for auditable, and often predictable reasons.
You can expect to see significant growth in your savings over the life of your UCG onsite supply contract compared to the alternative of using vaporized bulk liquid products.
Bulk liquid products require twice the amount of power to produce, and have significant diesel fuel cost related distribution costs - all of which combine to raise the price of delivered liquids faster than the cost of making gaseous products on-site.
|What Type of On-site Gas Generation / Production Plant Will Be Used to Supply My Needs?|
UIG will assess
expected usage pattern (average rate, peak rates, hourly and seasonal
fluctuations, plus anticipated changes in usage over the next several years) and
your product purity requirements. UCG will offer a supply
solution which combines a "right-sized" production facility with an
appropriate backup and/ or supplemental liquid storage and vaporization
Depending upon projected average usage rates, purity required and demand patterns, nitrogen users will typically be served using conventional cryogenic nitrogen generators. In some cases, a non-cryogenic production system or a LIN-assist plant will be recommended. Oxygen users will usually be offered a supply based on a cryogenic oxygen generator. In some cases a non-cryogenic VPSA plant may be an appropriate choice.
Whatever type of plant is chosen, the proposed on-site supply system will be a cost effective solution to the agreed requirements, and system performance will be guaranteed. In many cases the plant will be selected to allow for cost effective production rate increases to accommodate anticipated growth in demand.
|What About Backup Liquid?|
Backup liquid vaporization systems
are installed to avoid disruptions of
supply due to power failures or maintenance requirements. UCG will provide
backup liquid at competitive prices.
UCG is unique in its approach to the supply of backup liquid and the associated storage and vaporization systems:
Customers can be sure of highly competitive prices for their backup bulk liquid needs throughout the term of UCG onsite supply contract.
|Who Handles Operation and Maintenance of the Onsite Gas Generation System?|
|It is Universal Cryo Gas' responsibility to operate and maintain the facility.
UCG equips its plants with computer control systems that provide highly automated and sophisticated control of the plant. Alarms are indicated locally, and transmitted to local operations personnel and to UCG home office operations support personnel. Shutdowns are automatic when out-of-range conditions exceed pre-set limits. (Backup systems will activate automatically to ensure uninterrupted delivery of on-spec product.)
UCG plant operators verify proper operation, optimize plant settings to reflect changes in demand patterns, weather, and other factors, and perform routine maintenance. Plant operation is also monitored remotely by Home Office and Regional personnel. Periodic maintenance is scheduled and confirmed on a regular basis.
The bottom line for you, the customer, is that UCG will guarantee plant availability, do everything possible to ensure that guarantees are met, and provide protection against extra costs should UCG fail to meet its product availability guarantees.
|Are There Other Options That May Increase My Savings or Increase Supply Reliability?|
If there is sufficient local demand for merchant liquid products in the area (liquid oxygen and/ or liquid nitrogen) UIG / UCG may suggest installing a "piggyback" gas and liquid production plant as an option.
Adding liquid production at an onsite gas production site requires additional equipment (and additional liquid storage). These additions permit higher production rates and support distribution of large quantities of liquid products. When UCG is able to justify installation of a plant that will serve multiple customers, UCG is able to offer lower cost product to the original on-site gas customer (the host plant). The host plant also benefits from enhanced supply reliability due to the large amount of liquid product which will be stored on the site.

|When Should I Begin to Investigate Supply Options?|
If you currently purchase onsite-produced gas or liquid products, and wish to investigate producer/ supplier alternatives, you should begin to seriously examine potential options well in advance of the end of your current supply period.
For most users, this means starting at least two, and preferably three years prior to the end of their current contractual supply period.
Waiting too long to begin this process may effectively deprive the user of the ability to obtain competitive offerings from UCG or any other potential supplier. Most liquid and gas supply contracts contain notification period clauses which must be adhered to if automatic extension periods are to be avoided. However, that is only one of several potential impediments to changing supplier.
Unless a user starts investigating alternatives at least 2 years in advance of the end of the current supplier's supply period, there may not be time to finalize an alternative supply contract and install necessary equipment prior to termination of the current product supply arrangements.
