Emission Control Engineering

Emission Control Systems Engineering

Focus personnel have broad experience in providing process engineering services for air pollution control projects. Relevant applications include particulate collection, mercury and other metal controls, acid gas scrubbing, organic emissions controls, and nitrogen oxide emission controls.

Numerous projects have been completed that involved:

	Emission characterization
	Identification of performance improvements for existing controls
	Feasibility studies to evaluate retrofit of existing controls and to compare control alternatives
	Conceptual and process design
	Air pollution control equipment selection and specification
	Vent collection system design
	Procurement and installation of air pollution control systems
	Startup, shakedown, and trouble shooting of air pollution control equipment
	Preparation of operating manuals and operator training

Air pollution control systems have been designed for treating emissions from both thermal treatment processes and a variety of types of industrial processes. Specific types of air pollution control unit operations that have been designed, operated, or tested by Focus personnel include:

• Carbon adsorption systems
• Condensers
• Coolers
• Quench chambers
• Venturi scrubbers
• Spray dryers
• NOx control technologies

• Dry sorbent injection
systems
• Baghouses
• Packed and spray scrubbers
• Ionizing wet scrubbers
• Electrostatic precipitators
• Fume incineration systems
• Catalytic oxidizers
