Bundy Environmental Technology performed a turnkey project to demolish a twenty year old precipitator and replace it with a four (4) module BET fabric filter (baghouse) on a thermal oxidizer at a Cape Fear, NC chemical plant.
The contract was awarded in March 1999, demolition started seven months later, and the new system went into operation about one year after the contract date. The system includes the original evaporative cooler, the new baghouse with lift-off top lid bag access, and a push-pull fan system. Ancillary equipment included a bulk bag ash removal system, access and service provisions, and compressed air system.

The medical waste incinerator market has become active due to the age of old systems and stringent MACT standards. BET has contracts for the replacement of a wet scrubber system with a dry scrubber at a hospital in Florida (now operating), and for the replacement of a competitor�s dry scrubber at an Ohio hospital.

Kaiser Aluminum and Chemical Co. awarded BET the contract to provide a baghouse for their rotary coke cooler at the Mead, WA plant.
The process exhaust is almost exclusively the water that is evaporated to cool the coke. This obviously presented a threat of condensation and plugging in the baghouse, which was made more difficult by wide temperature swings from below the dewpoint to above the 500�F temperature limit of the baghouse. BET solved the problem through the use of the integrated heating and cooling systems. There was a partnership attitude between BET, Kaiser, and the engineer, Unifield, that led to a successful, compliant, easily operated system.

BET provided a turnkey retrofit baghouse system for four (4) coal fired boilers with a total steaming capacity of 800,000 lbs per hour. There was one ten module and one twelve module BETA style filter system.
Equipment included ductwork, sub-support structure, baghouse systems, plenums and manifolds, process and module valves, by-pass valves, penthouses, cranes, access systems, booster fans, ash removal, electrical control room, and stack monitoring system. Field work included foundation design and installation, equipment demolition and modification, new system erection, wiring, piping, insulation, check-out, startup, tuning and emission testing. Unique challenges included the placement of the equipment over an operating railroad track and protection of a critical nearby electrical substation.

	In cooperation with the local electric utility company, a major paper mill replaced five old Dutch oven hogged fuel boilers with a single 435,000 lb/hr wood fired cogenerating boiler. This required a major expansion of the existing Standard Havens baghouse system, which had provided 15 years of successful, low maintenance operation and was still in excellent condition.
The primary challenge in utilizing the old system was related to space. It had been blocked on both sides and there was limited access on each end. An unusual off-center inlet and outlet design and no room to widen the manifolds further complicated the retrofit. The new boiler required a 40% increase in gas volume with more restrictive outlet emissions, and the outage time allowed for conversion was extremely short. BET, with its decendency from Standard Havens, had intimate knowledge of this operation and a long term relationship with the customer. We were able to provide a system that met all the requirements. The turnkey upgrade readily handled the increased volume, did not require any additional plan view area. The outage for conversion required less than two weeks, and the project was completed on schedule and within budget.

BET supplied a complete dry scrubber system for the on-site medical waste incinerator at this university hospital in 1993. The turnkey project presented several unique challenges, including the requirement to place equipment at ground level sites and at multiple roof locations, resulting in total exposure of the equipment to severe New York weather conditions.
When EPA gathered data on the emissions from existing medical waste incinerator dry scrubbers to be the basis for MACT standards, this BET system was cited as the best performing of all installations. Measured emissions of particulates, HCl, dioxin/furans, and 12 other individual pollutants ranged from 0.1% to about 50% of the limits to be allowed under the MACT standards for large new sources.

	A competitor's wet scrubber system that was supplied with this commercial waste incinerator had failed to comply with county air quality regulations, and the plant was forced to sit idle. Ultimately the company gave up on the wet system and solicited bids for replacement with a dry scrubber.
BET was the selected vendor and provided a complete replacement system, which included an evaporative cooler, dry reagent injection system, baghouse, ID fan, and ancillary equipment. Because of the previous experience, the need for highly reliable operation and a fast-track schedule were especially critical.

A good example of BET's partnering philosophy involves this specialty glass plant where a competitor's thermal oxidizer and dry scrubber system never worked properly. The operating and performance problems were so severe that the company was actually prevented from running their production facility.
After several months of fruitless efforts to fix the original system, the company was ready to seek help elsewhere. BET was selected to provide and guarantee a reliable, successful system. The thermal oxidizer was substantially modified; the competitor's spray dryer was expanded and converted to an evaporative cooler with a new spray system; a new dry reagent injection system was added; the old baghouse was replaced; a new I.D. fan was installed; and the control system was totally revised and upgraded. This project had a very aggressive schedule which was achieved in large part because of the extremely cooperative relationship between BET and the client.

	BET retrofitted a four module BETA style baghouse on an 80,000 lb/hour low sulfur, spreader stoker, coal fired boiler at this chemical plant.
BET was responsible for the design, supply and installation of this high quality compliant, reliable, durable baghouse system. The project was completed on schedule and at budget.

A Birmingham, Alabama hospital selected BET from eight bidders to supply a turnkey dry scrubber system for their existing fixed hearth, on-site, medical waste incinerator.
The system included a stack extension and by-pass cap for the incinerator, refractory lined breeching, an evaporative cooler, dry lime storage and injection system, baghouse, I.D. fan, discharge stack and all accessories. The installation responsibilities were for complete foundations, erection, wiring, piping, refractory, insulations, etc.

D E T R O I T, M I & C O C O A, F L
	A commercial medical waste disposal company purchased complete BET dry scrubbers for its facilities in Detroit, Michigan and Cocoa, Florida. In both cases, dry scrubbers with multiple module baghouses were used on the fixed hearth incinerators.
