Pneumatic Conveying and Bulk Material Handling – Part 1

Nol-Tec Systems specializes in pneumatic dry bulk materials handling for a wide variety of industries. We work with our clients to design custom-engineered system solutions from proposal through installation. Our mechanical and electrical engineers are experienced, so they know how to anticipate challenges, and make economic recommendations to ensure optimal performance. We’re proud to offer innovative, customized service that is cutting edge in the industry.

Industry segments covered include food processing, ceramics, building materials, plastics, rubber, pollution mitigation and foundry, to name a few. We transfer the materials through pneumatic conveying, where air or a similar type of gas is used to move the substance through an enclosed pipeline. This can be done either by pressure or vacuum, dense or dilute phase, depending on the material and its characteristics.

In the industries we support, there are a number of variables in the materials that need to be transported. Particle size, distribution, bulk density, abrasiveness, toxicity, cohesiveness, moisture content and friability must be taken into consideration when designing a conveying system. In addition, the system design must consider rate, power requirements, transport distances, layout and footprint of the current processing system, and operating costs. It’s extremely important that you work with an experienced pneumatic conveying system designer to avoid potential pitfalls.

With over 30 years of experience, Nol-Tec offers the expertise you need. From start to finish, we anticipate potential challenges, configure the ideal design, oversee the installation process, and provide you with service across the full lifecycle of your equipment. Whether you require dilute phase (particles fully suspended in a low pressure, high velocity environment) or dense phase (non-suspended particles, moving in a high pressure, low velocity atmosphere), our team has the background and specialized knowledge needed to make the most cost effective and efficient decisions with you.

In the next post we will discuss how Nol-Tec has taken its pneumatic conveying expertise into the arena of pollution mitigation for fossil fueled electrical generation facilities and industrial boilers using our Sorb-N-Ject technology.

Cleaner Options for Sustainable Energy

Sustainability is a major buzzword in business today, but what does it mean for energy production and waste disposal? On the production side of the equation, one major initiative being undertaken in the industrial field has been using common by-products as a source of fuel (biomass). This waste-to-energy conversion not only results in a cleaner environment, but also represents an opportunity for renewable and sustainable energy development.

On the waste side of the picture, sustainability can mean finding ways to make the byproducts of energy production cleaner.  For both biomass and coal-fired power plants, the necessity for cleaner energy has been made even more apparent, thanks to the Mercury and Air Toxics Standards (MATS) regulation. The new standards limit emissions of mercury (Hg), hydrochloric acid (HCl), and filterable particulate matter (fPM) from power plants to benefit public health. They also regulate SO2, SO3, and HF emissions.

Mercury and hydrochloric acid in particular are well-known by-products of coal-fired plants, as well as from biomass fuel, creating a need for better options in this industry.

Dry sorbent injection (DSI) is one method ideally suited to aid in pollution mitigation of all these requlated emissions. It neutralizes harmful gases before they have a chance to be released into the atmosphere. This is a major step forward in the power generation field.

This process will be discussed more in depth at the 15th Annual Electric Power Conference & Exhibition. The event takes place May 14 to 16, 2013 in Rosemont,IL. Nol-Tec Systems’ Chemical Engineer Brent Tidemann will be speaking on Wednesday, May 15 at 8:30AM. His presentation, titled, “DSI for HCl and Mercury” will discuss DSI technology and its applications for HCl and mercury mitigation. This is a must-attend presentation for anyone in the waste-to-energy field or who wants to learn more about new energy practices.
