Reactor Cooling
Sometimes, having control over your manufacturing process
is all about maintaining the correct temperature. If you have the need to
achieve very low-temperatures in your chemical synthesis or if you need to
rapidly remove evolved heat from a reaction vessel, we can offer you a
variety of systems to help you do just that. At BOC, our CUMULUS™ and DCOOL™
liquid nitrogen-based cooling systems can be used for a wide range of
applications including cooling fluids in reactors, crystallisers,
lyophilisers, extraction vessels and other process equipment. Compared with
mechanical refrigeration, cryogenic cooling offers several advantages
including the ability to achieve lower temperatures more rapidly, simplicity
of operation and maintenance, reduced power demand, a smaller footprint, and
no environmentally harmful emissions.
All of our reactor cooling systems can be tailored to meet your specific
needs, and our dedicated staff will work with you to find the system that
provides optimum results for your business.
DCOOL™ Direct Injection Cooling
The DCOOL™ Direct Injection Cooling System uses a proprietary
non-freezing injection system to cool fluids by injecting liquid
nitrogen directly in the reaction vessel. The direct injection of liquid
nitrogen into the reaction vessel allows heat to be removed rapidly.
This helps shorten batch time and enhances productivity by reducing
by-product formation. By applying this technology, we were able to help
a leading chemical manufacturer reduce their batch cool time from four
hours to one hour, while cooling from room temperature to -40°C. Our
ability to help maintain consistent production environments with
temperature variations of less than 1°C greatly enhances productivity by
reducing by-product formation. The key to this technology is our process
control, efficient solvent recovery system and innovative injection
nozzle designs.
CUMULUS™ Fluid Temperature Control Systems
The CUMULUS™ Fluid Temperature Control System is part of the line of
indirect cooling systems that use liquid nitrogen to cool a heat
transfer fluid. This fluid can be circulated to various types of process
equipment to achieve temperatures of -100°C or below with a degree of
control within 1°C. The compact and reliable system can be
installed indoors or outdoors and comes equipped with its own
proprietary control system. The liquid nitrogen used in CUMULUS systems
never comes in contact with the heat transfer fluid or the reactor
contents, resulting in a clean gaseous nitrogen that is available for
reuse elsewhere in the plant, for example in blanketing applications.
The CUMULUS Fluid Temperature Control Systems are available in five
cooling capacities and three frame sizes ranging from a 5 kW laboratory
module to a 100 kW production unit.
