Treatment: Air Abatement
Organic vapors extracted from contaminated
soil during Soil Venting or from contaminated groundwater
treated in the S.A.V.E.ô system's Spray Aeration
process typically requires treatment to meet Volatile
Organic Compound (VOC) emissions standards. Depending
on the concentration and composition of the organic
vapors, RSI offers several treatment technologies.
Using RSIís specially designed
Internal combustion engine for high concentrations of total petroleum hydrocarbons
(TPH) from fuel spills, at or above the Lower Explosion
Limit (LEL), compressive thermal oxidation via our
computer controlled modified internal combustion
engine (ICE) is the most cost-effective process
on the market today. The ICE is also effective on
TPH below the LEL by simply adding supplementary
fuel from another source, for example, natural gas,
propane or gasoline.
Catalytic Oxidation Module
Our catalytic oxidation module destroys additional
TPH vapors, adding overall performance not seen
in the industry. It is also useful when the total
combined gas flow rate from Soil Venting and Spray
Aeration exceeds the destruction capacity of the
del V3ith Catalytic Oxidizer and Hexchanger
A key component to our success is that the catalytic module
increases the total S.A.V.E.ô system capacity, with
two off-gas treatment units (ICE and catalytic oxidation)
operating simultaneously, in parallel. Our catalytic
module requires no outside energy source as all
required power is derived from the waste energy
of the ICE. No one offers a better treatment cost
per cubic foot treated than RSIís patented remediation

Organic Vapor Air Abatement Module
Chlorinated organic vapors can be treated via
activated carbon adsorption units or in a catalytic
unit specifically developed for chlorinated organics.
The destruction of chlorinated organics results
in the production of hydrochloric acid (HCl); the
acid may be removed from the emissions using a scrubber
system provided with this module.
For low levels
of chlorinated vapors in a petroleum hydrocarbon
spill, the vapors may be treated in the ICE, following
RSI's modified operating instructions with prior
Phoenix S.A.V.E.ô Controller
Maintaining optimal A/F ratio is challenging with
variations in site conditions, such as fluctuating
hydrocarbon , oxygen or carbon dioxide concentrations.
Competing systems require constant operator input
to adjust to changing conditions.
the Phoenix engine controller to handle virtually
any change in site conditions, from a slug of free
product to a temporary loss of supplemental fuel.
It maximizes vapor flow from the extraction wells
and minimizes alternate fuel consumption simultaneously.
The electronic controller senses any deviation from
the stoichiometric air-to-fuel (A/F) ratio to optimize
contaminant destruction and meet stringent air emissions
standards. With the ability to optimize system operation
to meet Air Quality Control standards, the patented
computerized control system is cutting edge technology.
The optional "Project Manager" software module allows
for control of the "Smart Valve Manifold System".
This unique system optimizes BTUs extracted from
the contamination source by purposely rotating from
well to well and determining the most efficient
combination of wells to extract from.
