What is Resistive Splitting and Why Use It?

For utilities and industrial boilers, capital costs are one large consideration when installing air pollution mitigation. However, ongoing maintenance and materials costs can have an even great impact over time. Dry sorbent injection (DSI) systems keep capital costs in check, but sorbent effectiveness must be boosted for cost effectiveness. Here’s where Nol-Tec’s state-of-the-industry resistive splitter design comes in.

Our innovative Sorb-N-Ject® system designs make the most of sorbent materials. With our resistive splitter technology, sorbent materials do not take the path of least resistance and are instead dispersed equally through each injection lance. Non-resistive splitting, on the other hand, leaves gaps in the sorbent flow, so pollutants may or may not interact with the chemical. The process of resistive splitting fills the duct with a consistent flow of sorbent, so flue gases stream through a curtain of sorbent. This ensures maximum contact between gases and sorbent, which results in efficient chemical interaction and mitigation—and decreases sorbent usage.

Nol-Tec’s in-house experts developed this resistive splitting technology, based on our 30 years of experience in the pneumatic conveying industry. Resistive splitting increases the effectiveness of your sorbent, decreasing overhead costs. It reduces abrasion on the equipment, so a broader range of sorbents can be considered, while lowering your maintenance costs. And we’ve designed it to install easily at the main convey pipe, which lowers the costs to begin using the technology.

Remaining competitive today means keeping costs down and efficiency up. With the innovation and proven success of resistive splitting, that’s exactly what Nol-Tec helps you achieve.

The diversity of our employees is one of our biggest assets. Collectively, they have more than 100 years of experience in the industry, and have handled countless materials in a wide variety of applications. Our staff members provide excellent service to fulfill your ever-changing project needs.

Engineering Design

We examine your needs during the project’s proposal phase, and ask questions in order to design an economical, high-quality, custom-engineered system. This means fewer change orders, to keep the project moving forward on time.

Materials Testing

Our offices in the United States and Italy have on-site materials testing facilities, in which we can accurately determine a system’s rate, air consumption, material flow characteristics, and product degradation statistics by replicating your field conditions. You can be sure our design will work for you, before making the commitment to  a major installation or update.

Equipment Pre-Assembly

We can assemble all types of bulk material handling modules. We wire and pipe our pre-assembled units to the fullest practical extent, and then test each one electrically and mechanically to ensure proper operation and fit. We deliver a working system to your door, saving you time in the installation.

Start-up and Field Service

Our services include installation, start-up, training, and field services. From basic phone support to turnkey installations, we can assist you every step of the way. We make sure your new system works with your legacy processes, keeping rework costs to a minimum.

Technical Support

When you purchase a Nol-Tec system, our mechanical and electrical engineers will address any of your concerns and provide technical assistance over the full lifecycle of your equipment. You can depend on us to be there for any question, any time.
