The Glamorous World of Rendering

What is Rendering:rendering industries

Rendering is the process of melting down animal tissues and fats into usable final products. This process in conducted on a large scale to meet the need for fats and tallow for several leading global industries such as cosmetics, cleaning chemicals, pharmaceuticals, oils, animal feed, candles, and bio-diesel, to name a few.

The process of rendering requires the animal tissues to be finely chopped or ground and then melted down using medium to high heat. For non-edible rendering, the tissue is heated in a steam-jacketed vessel which removes moisture from the product. When the moisture is removed the fat is released from the cells where it melts down into a drain and is collected for use. The remaining tissue is then pressed so any remaining fat can be dredged out of the material. The fat-less remains are then ground up and used to make meat and bone meals. [Read more…]

Dimethyl Sulfide

What is Dimethyl Sulfide?

Dimethyl Sulfide

Dimethyl sulfide (DMS), also known as methylthiomethane, is an organosulfur compound. It is a methyl sulfide, in which the sulfur atom is substituted by two methyl groups, with the chemical formula of (CH3)2S. It is a highly flammable straw-colored liquid, with a boiling point of 37 degrees Celsius, or 99 degrees Fahrenheit. This is a compound that is easily recognized by its foul odor, that is often described as “cabbage like”. Unlike many other organosulfur compounds, this disagreeable odor is present in even low concentrations of DMS. Dimethyl sulfide is the product of dimethylsulfoniopropionate (DMSP) breakdown, and is also the result of bacterial metabolism of methanethiol.

NOx Abatement

Part 3 of Abating Hazardous Air Pollutants: NOx

What is NOx? The term NOx refers to the family of air polluting chemical compounds, Nitrogen Oxides. NOx represents seven different compounds although only one, Nitrogen Dioxide, is regulated by the EPA. Nitrogen Dioxide (NO2) is carefully monitored by the EPA as not only an air pollutant but also for its reaction with the ozone and the creation of acid rain. NO2 is reddish-brown gas with a bitter odor similar to that of Chlorine. NO2 is also commonly referred to as Nitrogen Oxide and Deutoxide of Nitrogen and is highly reactive. NOx

NO2 is an intermediate in the manufacturing nitric acid. Nitric acid is a nitrating agent in the manufacturing of chemical explosives, as a flour bleaching agent, as an inhibitor for acrylates and an oxidizer in rocket fuel. It was used in the Titan rockets which launched Project Gemini, in numerous unmanned space probes and remains in use for space travel in the maneuvering thrusters of the Space Shuttle. [Read more…]

Aqueous RTO: Features and Benefits

By designing and custom manufacturing oxidizers in-house, we are able to provide the lowest cost of ownership possible. When you have the resources and the team of experts, a company can build what it wants, and what its clients need.

In emission control technology, Regenerative Thermal Oxidizers (RTO) were developed for large volumes and low VOC concentration air regenerative-thermal-oxidizer-assemblypollution applications. They carry a low operating cost, and reliably harness the principle of thermal oxidation, which utilizes the process of regeneration for internal heat recovery; superior pollution control devices for air and vapor pollutants. Highly energy-efficient, an RTO is ideal for long, continuous operations. They even achieve high levels of VOC destruction to keep processes well below required DRE emission levels. [Read more…]
