Technology Center

Selas Fluid's Technology Center and Pilot Plant is located in Conshohocken, PA USA, approximately five miles from the our corporate offices in Blue Bell, PA USA. Erected in 2000, this facility replaced the former pilot plant established at this location in the early 1950’s. The activities performed at the Technology Center include:
  • Research and development activities for the various combustion technologies offered by the Company
  • Active demonstrations of system performance to clients to validate processes
  • Classroom and operational instruction to those interested in developing a more in depth understanding of combustion and incineration systems

Technology Center - Pilot Plant

The pilot plant includes a combination of permanent and modular systems used for testing process operations. Permanent systems include:
  • A 1.3 MM Btu/hr (0.4MW) down fired Sub-X thermal oxidizer with a submerged quench, high-energy venturi scrubber, and a packed column for acid gas treatment. This unit may be used for testing with waste gases and liquids.
  • A 3 MM Btu/hr (0.9MW) staged combustion (reducing-oxidizing) thermal oxidizer with a countercurrent, spray quench and combination venturi/packed column scrubber using sub-cooled scrubber liquor applicable to waste gases and liquids.
  • A 40 MM Btu/hr (11.8MW) water-cooled furnace for conventional fuel combustion development testing.
  • A 1 MM Btu/hr (0.3MW) GR flameless thermal oxidizer (waste gases) with internal heat recovery to minimize support fuel requirements.
  • A GH12 flameless thermal oxidizer for waste gas oxidation.
The modular units provide a system of "building" customized combustion systems for a given need. Currently, the inventory of combustion equipment at the facility will allow configuration as either a water-cooled or refractory-lined design with heat releases up to 10MM Btu/hr (2.9MW). In addition, various auxiliary equipment arrangements may be prepared for tail gas clean up such as a partial quench and fabric filter to demonstrate dry inorganic particulate removal compliance with environmental emission regulations. Waste feed options include a wide diversity of both gases and liquids.

Technology Center - Control Room

A local control room contains both the monitoring and control equipment to operate the various systems. Controlled by Allen-Bradley SLC 500 programmable logic controllers (PLCs), the systems are accessed by Human-Machine Interface (HMI). Systems are fully instrumented with automatic operation and all safety interlocks.

High temperature cameras located on select vessels provide a visual insight into the internal operations in the combustion locations. A continuous emission monitoring system (CEMs) with auto calibration and data logging monitors a multiplicity of stack gas components including O2, CO2, CO, SO2, NOx (NO and NO2), and THC.

In close proximity to the control room is a chemical laboratory and a working office for visitors including desks, tables, telephone, and high speed internet connection.

Technology Center - Demonstrations

The pilot plant is EPA permitted as a test facility; in fact, it has been used to perform demonstration testing for various governmental agencies such as the USEPA, the Department of Energy, and the Department of Defense.

Incineration and thermal oxidation demonstrations may be performed in one of two ways: utilizing actual waste from the client's facility, or via preparation of a waste composition at the Technology Center.

Waste from the client’s facility can be received at the Technology Center, providing the client supplies all necessary manifests and shipping clearances. Our operating personnel are HAZMAT trained and certified. This option typically applies to liquid waste due to storage requirements. Our facility has a 5000 gallon storage tank used for such purposes.

Actual preparation of a waste composition can be managed at the Technology Center, reducing the costs and risks of transporting such material. With this option, ingredients are purchased by our staff, and a mixture is prepared to simulate the actual waste; we are able to prepare both liquid and gaseous compositions.
