About Us Mech-Chem is a full service engineering and design firm that specializes in the engineering, design, fabrication and construction of chemical processes and operations. Mech-Chem was founded in 1984 specializing in acid and chemical corrosion technologies and process design. Over the last 30 years Mech-Chem has grown to include a network of dozens of professionals including an in-house staff of full-time engineers, designers, and PLC programmers. Our company’s mission is to design, engineer and build industrial processes and systems that not only meet our clients’ production and manufacturing objectives but also meet their environmental, health and safety goals. Mech-Chem's knowledge of chemical engineering and processing, along with our industrial experience in the design and start-up of these operating systems, gives us the unique ability to design and build fully integrated systems. This expertise allows us to provide our clients with effective processing systems and operations using the best available technology with state of the art PLC/PC automation and controls Fume Scrubbers And Ventilation Systems (Click to Download pdf) Properly engineered and designed ventilation and fume scrubbing systems can prevent environmental releases, ensure regulatory compliance, and protect employee health and safety. Mech-Chem provides the complete scope of services for fume ventilation and scrubbing systems including the following: • Engineering & Design • Fume Scrubber Fabrication • Custom Hoods & Enclosures • Complete Ventilation Systems • Makeup Air Systems • System Installation & Start-up • System Upgrades & Repairs • Airflow Measurements & Balancing • Preventative Maintenance Programs Mech-Chem brings 25 years of chemical process design experience and expertise to the design, fabrication, and installation of our ventilation and fume scrubber systems. Our company provides complete professional solutions that can control and treat our client's fume and exhaust problems. Standards and Custom Built Scrubbers Mech-Chem designs, fabricates, and installs many types of fume scrubbers that are used for removing fumes, mists, vapors, particulates, and odors from the exhaust streams. These fume scrubbers offer: • Absorption and neutralization of acid fumes • Absorption and neutralization of alkaline fumes • Removal of solvents from exhaust streams • Removal of particulates from exhaust streams • Standard sizes: 2,500 to 50,000 CFM systems • Fume scrubbers are designed and fabricated to meet the required chemical application •Fume scrubbers are constructed using the appropriate materials to handle corrosive chemical environments A packed bed with countercurrent flow of the scrubbing solution is the heart of the fume scrubber. Mech-Chem's fume scrubbers are designed to provide very efficient removal of acid, chemical, solvent and NO2 fumes, mists, vapors, entrained liquids, particulates, and noxious corrosive gases from the exhaust air stream. Fume Scrubbers Controls—Operator Interface
Mech-Chem designs and programs operator interface screens to allow equipment and set point parameters to be adjusted. Each individual system has a screen which functions as the monitoring and control point. These screens allow for viewing of equipment operation as well as display of the alarms and set points. Three of the systems monitored and controlled are the ventilation, fume scrubbing, and air makeup systems. Several key points are controlled and alarms are programmed in the PLC to control and indicate if any of the equipment or operating criteria is not met, such as the following: • Circulation Pumps Start/Stop Control • Motor Overload • Circulation Flow Rate • Chemical Feed Pump • pH of Reservoir • pH Set Points • Level in Scrubber Reservoir • Blow Down • Chemical Feed Drum Level • Makeup Air System Flow • Push Air System Flow • Static Pressure of Scrubber • Water Makeup • Makeup Air and Scrubber Blower |
