Facility
Overview
Clean Earth of Philadelphia, Inc. operates a thermal treatment facility located in (South) Philadelphia, PA situated on 8.3 acres. The facility layout consists of a contaminated-material storage building, a medium temperature thermal processing unit, temporary storage for treated material, an on-site laboratory, and office space. The processing plant, which is permitted to operate 24 hours a day, seven days a week, is comprised of a rotary dryer to remove contaminants from the soil, a thermal oxidizer for hydrocarbon destruction, and a bag house to remove dust from the flue gas.
The plant can reach treatment temperatures of up to 1000°F and can handle a wide variety of volatile and semi-volatile contaminants ranging from gasoline and alcohols to phenols and coal tar residuals. CEP incorporates a high temperature plant configuration that has a process flow through the dryer, cyclone, oxidizer, heat exchanger, and baghouse thus ensuring our clients a safe and effective treatment solution. The on-site laboratory provides the necessary analysis to ensure compliance and quality control for incoming waste streams and post treatment effectiveness. The on-site analysis can be compared with the certified pre-approval analysis providing the facility with direct control over waste acceptance, reducing the potential for unauthorized waste streams.
Treatment
Technology Platform
Thermal Treatment: The primary waste treatment component is a rotary dryer measuring 8.5 feet in diameter by 40 feet long and is constructed of stainless steel. Waste enters the rotating dryer which is heated to elevated temperatures causing the evaporation of water and the volatilization of the contaminants. After a retention time in the dryer, the treated media enters a soil conditioner (pugmill) where water and/or residual wastes such as sludges, and other wastes beneficially reused as soil additives are mixed to cool and rehydrate the material. The cooled, moist soil is stockpiled, sampled, and tested by an independent certified laboratory ensuring effective treatment and fulfillment of reuse standards.
The fume from the dryer contains the hydrocarbons removed from the contaminated soil. The fume first enters a cyclone to minimize particulate matter from entering the oxidizer. The fume then is burned in a gas-fired oxidizer at 1500ºF to assure destruction. The flue gas is cooled in an air-to-air heat exchanger and passed through a baghouse filter to remove the remaining particulate matter prior to being discharged into the atmosphere.
Adequate instrumentation and automatic process controls allow for safe operation of the thermal processing system. Automatic safety controls, temperature gauges, and recording devices allow the plant to operate only within strict parameter ranges while a computerized operating system controls the monitoring and retention of data and analysis of plant performance.
