Advantages / Comparison of vacuum insulated and PUF insulated Liquid CO2 tanks.

IS VACUUM INSULATED STORAGE TANK FOR STORING CO2 IS BETTER THAN USING PUF INSULATED TANKS? AND WHY?

The choice between a PUF insulated and a vacuum insulated is a matter of economics and project logistics. So one is better than the other only in the matter of which has a cheaper overall installed cost.

COMPARISON BETWEEN VACUUM INSULATED AND PUF INSULATED LIQUID CO2 TANKS:

The PUF insulated CO2 storage tanks have had an excellent history of durability and service.
The PUF insulated tanks are easy to repair and maintain with least repair cost and downtime
Easy to maintain with less maintenance cost
Longer life
Less capital cost
Easy to install
PUF insulation of 8” thickness gives insulation property as good as vacuum insulated tanks

Carbon Dioxide tanks must maintain pressure between 17 to 27 bar for CO2 storage. When CO2 is drawn from the tank, lot of heat is also removed thereby lowering the temperature and pressure and this removal to heat must be replaced to maintain proper working pressure. Due to the increased insulation value on vacuum insulated tanks there is very little heat entry. Hence a vaporizer is required to maintain the proper operating pressure. If the pressure inside the unit is allowed to drop below 60.4 psig the CO2 will convert to dry ice inside the unit. The unit will then have to be removed from service for a prolonged period of time to allow pressure to return to normal operating conditions. In this type of application, the heat entry into PUF insulated tanks can be very helpful.

As regards vaporizers and refrigeration systems the same is required for both PUF insulated CO2 tanks as well as vacuum insulated CO2 tanks. It is misinformation to say that either PUF or vacuum insulated carbon dioxide tanks will never require a vaporizer or refrigeration system. Most importantly, the application and frequency of usage and amount of product withdrawn will determine the best type of insulation and accessories required.

Several factors should be taken into consideration, when determining the type of units. (1) Where space is limited, vertical CO2 tanks are more readily accepted and where there are no limitations on space, horizontal CO2 storage tanks are more economical choice. CO2 storage tanks are generally only available in sizes from 5 tons up to 200 tons capacity.

PUF insulated CO2 storage tanks are manufactured with a manhole and allows complete flexibility to add refrigeration if it is ever required. There has been misinformation stating that all urethane CO2 storage tanks require a refrigeration system. For applications where vapor or a large amount of liquid CO2 is withdrawn on a regular basis, no refrigeration system is required. External refrigeration system for those CO2 storage tanks without an evaporator coil inside the unit are very easy to install, safe to operate and maintain

Both PUF and vacuum insulated CO2 storage tanks have a carbon steel vessel. These pressure vessels are manufactured in compliance with various international design code like ASME SECT VIII DIV 1 , ASME SECT VII DIV 2 , PD 5500 , CODAP 2000 , TEMA , AD MERKBLATTER etc .

The maintenance on PUF and vacuum insulated CO2 storage tanks differs. If a vacuum insulated unit loses its vacuum, the leak must be located and repaired and a new vacuum must be pulled on the unit. The downtime will vary depending on the extent of damage and the time required to locate the leak, make the repairs and pull a new vacuum on the unit. In most cases, on site repairs can be made. If the exterior of an aluminum jacketed PUF CO2 storage tank is damaged, the repair can be made locally with no downtime. If the outer jacket is not repaired, the insulation will eventually become saturated and the unit will have to be reinsulated.

In case of CO2 transport tanks PUF insulated tanks have comparatively lesser dead weight as compared to Vacuum insulated tanks and so they carry more products and the payload is increased.

There is a place in today's market for both urethane and vacuum insulated CO2 storage tanks. The customer should evaluate their particular needs and determine what type CO2 storage unit is best for their application.

CO2 RECOVERY PLANT

CO2 recovery plants are used to recover CO2 arising from various process like Distilleries, Fertilizers, Alcohol preparation, various chemical processes, Fermentation process, Lime stone chemical reactions etc. The basic object of these CO2 recovery plants is to trap this CO2 and them purify and liquefy the same for further use.

The process involves various stages as follows:

Trapping or collection of escaping CO2 gas vapours by using a buffer balloon
Passing through foam separator
Passing through gas scrubber where all water soluble impurities are remove
Drying of CO2
Compressing of CO2 in CO2 compressor
Removal of other impurities and odours in a regenerative purification and deodorizing system
Liquefaction of CO2 in refrigeration system
Storage of liquid CO2 in a CO2-storage tank.

CO2 PRODUCTION PLANT

CO2 production plants are used to recover CO2 arising from flue gases from boilers, generators and other processes. The basic object of these CO2 recovery plants is to trap this CO2 and them purify and liquefy the same for further use .

The process involves various stages as follows:

Trapping or collection of escaping CO2 gas vapours by passing the flue gas through absorber with aqueous solution of monoethanolamine (MEA)

FAQ - Question and answer

What is liquid bulk carbon dioxide?
Liquid bulk carbon dioxide is a safer, it is low-pressure alternative to high-pressure compressed gas cylinders. With the CO2 system, liquid bulk carbon dioxide is stored on the premises at a lower pressure in a steel holding tank, and is automatically refilled on a regular schedule based on your usage pattern. Our CO2 tanks are permanently installed at your location, so you don't need to worry about the hassle of changing cylinders. We offer liquid bulk carbon dioxide systems in several sizes, ranging from 500 Liters to 500000 Liters of carbon dioxide capacity, to fit the needs of your business.

Why use PUF insulated CO2 transport tanks:

In case of CO2 transport tanks PUF insulated tanks have comparatively lesser dead weight as compared to Vacuum insulated tanks and so they carry more product and the payload is increased .

Why use PUF insulated CO2 tanks instead of vacuum insulated tanks:
