The Importance of a Flexible Emission Control System Design (PDF Document)
Overview: Throughout the past decade the design capacity for ethanol plants has continually increased, requiring new designs for both production and backend emission control. As the capacity, and anticipated production and emission rates of ethanol plants have increased, the challenge to provide process and emission control technologies to match these demands has also grown. Efforts to standardize process designs often lead to equipment sizing issues or the inability to accommodate production beyond the design conditions of the emission control system.
Recent advancements in pollution emission control technologies as well as increased flexibility and a conservative system design all have resulted in a significant increase in the reliability and compatibility of the emission control system with various operational or process needs, while reducing the amount of VOCs and HAPs released into the atmosphere. These considerations have significantly benefited the ethanol industry.
Technology Selection Criteria for VOC Control (PDF Document)
Overview: The term VOC (volatile organic compound) represents a very broad classification of emissions. Organic gases as diverse as formaldehyde, benzene and chloroform are measured, classified and regulated as VOC.
Such a general definition presents a problem to engineers concerned with developing technologies to reduce VOC emissions. This paper presents an overview of the criteria that designers should consider when selecting a “tail-pipe” technology for abating VOC emissions.
Puff Minimization Control Technology (PDF Document)
Overview: NESTEC, Inc. employs the simple technique of minimizing the size and frequency of the puff, thereby increasing the overall destruction performance of the RTO. There are no additional moving parts and the RTO footprint is kept to a minimum.
