Microbulk Industrial Applications

Talk to a Microbulk Specialist
 

 

Analytical Laboratories

 Plasma

Supply for Inductively Coupled Plasma (ICP) units for analyzing non-organic materials 

Specimen Preparation 

Preparation of some specimens prior to testing  

Cold Traps 

Liquid nitrogen is used in a cold trap to capture impurities in a gaseous line.  

 

Biotechnology

Metabolic Gases 

Process Requirement, Performance, Reliability

 

Chemical

Inerting 

Inerting of chemicals in tanks and in transport 

Cooling of Exothermic Reaction 

Cooling chemical reactions in a jacketed reactor. 

Vapor Recovery 

Recovery of volatile vapors from processes by cooling the vapor to below its boiling temperature and turning it to liquid, them recovering the liquid. 

Pipe freezing 

Liquid nitrogen is put through custom jackets on the outside of a pipeline to freeze the liquid inside and create a plug.  These plugs are located on either side of a break to stop flow so the line may be serviced. 

Vacuum Breaking  

Gas is used to break vacuums in reactor tanks to prevent oxygen from contaminating the chemical 

 

Electronics 

Crystal Growth 

Used as an inert atmosphere for silicon crystal growth 

Cleaning 

Nitrogen is used to clean the surfaces of fiber optic strands prior to connecting to one another 

Soldering 

ICB (Interconnecting Circuit Boards) are soldered under a nitrogen atmosphere to prevent oxygen contamination 

 

Energy

Production

Higher purity hydrogen has a lower gas viscosity and density which improves cooling efficiency and Reduces friction losses and increases generator output

Production

Cost-effective and reliable means to decrease NOx emissions

 

Food 

Sparging 

Sparging non-carbonated drinks with nitrogen to remove dissolved oxygen 

Pressurizing 

Pressurizing of non-carbonated beverages in aluminum cans 

Injection  

Wastewater pH adjustment of discharge cleaning water 

Deboning 

Deboning of beef and/or chicken by cooling the meat on the bone to embrittlement temperature and fracturing off 

Pressurizing 

Pressurizing of non-carbonated beverages in aluminum cans 

Sausage Cooling 

Cooling sausage blending operation so fat does not liquefy. 

Batch Cooling 

Batch cooling of ground beef, pork or poultry to retain fat content. 

Cryo-Grinding 

Cryogenic grinding of high oil content or difficult to grind spices 

Extrusion Cooling 

Cooling of extruded foods to increase production 

Pneumatic Cooling 

Liquid nitrogen is injected into a bulk products transfer line to cool products such as flour. 

Mold Cooling 

Cooling of molded candy and gum for quick release from mold 

 

Manufacturing

Vulcanization-Tires

Vulcanization is a curing process that makes natural and synthetic rubber harder and more wear resistant.

Body – Combustion

Combustion processes use oxygen to melt scrap, refine the steel, and heat the furnaces that reheat steel slabs. 

Body – Heat Treating

Heat treating processes use hydrogen and nitrogen in annealing furnaces to strengthen and improve formability of the steel. We offer hydrogen in non-microbulk form.

Body – Welding

Welding processes use argon for steel.

Body – Heat Treating, Welding & Combustion

Welding processes use carbon dioxide for auto bodies.

Oxy-Fuel

Oxy-Fuel Conversion of Glass Furnaces

Welding

Most commonly used shielding gas, and is the only truly inert gas commonly used in welding.

Welding

CO2 decomposes to CO and O2 at welding temperatures, producing an oxidizing effect similar to a combination of argon plus 0-5% O2. 

Welding

O2 is added to shielding gas, where it helps produce a more stable arc, improves wetting of the weld edges and reduces weld spattering.

Heat Treating

Nitrogen-based protective atmosphere for their furnaces. 

Heat Treating

Atmospheres may be blended with small quantities reactive gases such as hydrogen.
