Overview

TARMAC INTERNATIONAL BUILDS & BUYS SOIL REMEDIATION EQUIPMENT

What Is Soil Remediation?

Thermal soil remediation is treating hydrocarbon contaminated soils (solids) with heat in a rotary dryer (desorber). Heat volatilizes the hydrocarbons into a vapor, leaving the soils remediated. Soil, oil field waste, refinery waste, tank bottoms can be thermally treated and remediated. Both Direct Fired and Indirect Fired rotary drying remediation systems are built by Tarmac International, Inc.

Tarmac: A Plant System Equipment Manufacturer

For more than 20 years, Tarmac International, Inc. has built complete thermal soil remediation plants worldwide. Our thermal soil remediation plants have production rates from 5 to 80 tons per hour. Systems can be portable or stationary. Tarmac International, Inc. designs and builds all components of the system.

Air Pollution Control:

After hydrocarbons are vaporized from the soil, the mission is to clean the rotary dryer off-gas with the following equipment components:

DIRECT FIRED PLANTS: cyclone, oxidizer, cooling heat exchanger, baghouse and acid gas scrubber

INDIRECT FIRED PLANTS: cyclone, high temperature baghouse, quench, acid gas scrubber and oxidizer
