Future-proofing biomass drying

In the development of new wood products or energy facilities, or when upgrading existing mills, a major focus is often on the equipment producing the final product. However, a critical aspect of the biomass drying process is the Dryer Island. It’s important to consider how dryers and heat energy systems can be more cost-effective and future-proof. Enhancements to process design can significantly improve the bottom line.

Typically, emissions control equipment, such as wet electrostatic precipitators (WESPs) or thermal oxidizers (regenerative thermal oxidizers or regenerative catalytic oxidizers), are the last item considered. Yet, prioritizing air pollution control early in the planning phase can lead to smoother project execution, reduced costs, and better environmental compliance—benefits that are especially critical during process upgrades when budgets may be tight, and the focus is on production throughput and quality.

At Mid-South Engineering, we don’t manufacture equipment, but our decades of experience have shown us the crucial role that air pollution control equipment plays in the design of Dryer Island. Recognizing the environmental impact of such equipment is vital; hence, we advocate for its early consideration in any project.
The environmental permitting process can be intricate and lengthy, necessitating collaboration among governmental permit writers, consulting engineers, and the facility itself. This becomes a critical long lead item for both new greenfield projects and brownfield upgrades. The layout of equipment, particularly pollution controls like WESPs and thermal oxidizers, plays a significant role in simplifying the permitting of new or upgraded facilities.

In established facilities with outdated equipment, upgrading dryers or heat sources poses challenges due to the finite service life of WESPs and thermal oxidizers. Given the advancements in technology since the previous installations, evaluating options for upgrading or replacing pollution control equipment is essential. Engaging with vendors early in the project can notably enhance efficiency and minimize downtime.

With Mid-South Engineering’s expertise, you can initiate the process engineering for pollution control equipment early, ensuring optimal management of your project’s schedule and budget.
