Reclamation of Petroleum Products,Solids and Contact Waters:

Description of AECs Birmingham, ALPetroleum Reclamation Facility

Process Description

AEC handles three main products in theReclamation Process.

Tank Bottom Solids Petroleum Contact Water Transmix fuels

Solids consisting of sand, dirt,emulsified product, solidified fuel andrust scale, that accumulate at thebase of petroleum storage tanks.

The solids are removed during tankcleaning and must be managed.

Tank Bottom Solids

Water which has been in contact withpetroleum products allowing dissolvedfractions of petroleum constituents to bereleased into the water.

i.e., - containment basin water- hydrostatic test water- contaminated groundwater- tank bottom solids water

Petroleum Contact Water (PCW)

By definition, Transmix is a mixture of gasolineand diesel fuels that result from various sourcessuch as the following:

- pipeline transfers- cross contamination of tanks- barge transfers- errors in unloading at service stations- comingling of treated recycle streams

Separation Processes

Separation Process

The Separation Process includes an oil/water separator, a specially designed

solids holding tank, afiltrate recovery tankand a product recoveryinformation system.

Solids Processing Building

The Solids Processing Building containsa filter press, a chilled two-stage vapor

recovery system, hightemperature dryer, andoff-gas oxygen analysissystem. This buildingwas designed as anexplosion-proof area.

Plate and Frame Filter Press

High Temperature Drying System

Allied Energy uses a high temperaturedryer with two-stage vapor recovery

system that ensures avery dry final powderproduct and recyclesany vapors back to therecovery system.

Petroleum Contact Water Treatment

Petroleum Contact Water is processedusing a Biological Sequential Batch

Reactor. Processedpetroleum contactwater is appropriatelysampled anddischarged under aState IndirectDischarge permit.

Transmix Distillation Operations

In April 2009, AECbegan operation ofa transmixdistillation columncapable ofprocessing 4500barrels of transmixper day .

Transmix Recovery Tanks

All transmix from the reclamationprocess is stored on-site and goes tothe new Transmix distillation facility.

This approach enablesAEC to reclaim thisfuel and use it for theoriginal intendedpurpose as is requiredby the RCRA Reg’s.

Transmix Distillation Operations

AEC’s lab has the ability to evaluate thecomposition of incoming materials

using a gaschromatograph,and analyze forsulfur and octaneas part of thequality control andcompliance efforts.

Petroleum Marketing Terminal

AEC maintains a full service petroleum marketingterminal that includes four loading lanes,blending operations and on-site QA/QC lab.
