Solvent Recovery

The current paradigm of solvent handling is to ask, what's the cheapest way for me to get rid of my
spent waste solvents? AAI approaches this problem differently. Instead of paying for someone
else to haul your waste, why not profit from it? AAI can do just that, with no capital cost to
you. Sound too good to be true? Let's look at the problem with a fresh set of eyes.

Process industries typically handle organic wastes in any combination of three ways: abatement of
VOCs, recycling of useful solvents, and disposal of waste solvents. The problem with this
approach is that it relies on costly steps which are designed only with the idea of reducing
emissions. Even to that end, VOC abatement systems often are only trading VOC emissions for
NOx, SOx, CO2, CO, Furans, Dioxins and other forms of pollution. Disposal is an ongoing cost,
and it ultimately causes pollution from the end handler.

AAI can provide solvent recovery systems on or near your site to handle solvents and VOC streams
at no cost or risk. The principle is simple. AAI's proprietary system uses your waste as a fuel to
produce purified CO, CO2, H2, Ar, N2 and/or CH4 depending on the desired products or power
configuration. These products are either sold by AAI on the open market, returned to the solvent
supplier at below-market prices, or used to generate on-site power. The system can be fully
financed by AAI, or purchased by a client for on-site purified gas and power production.

Functionally, the system replaces your VOC abatement and disposal steps. At a minimum, this
means eliminating your emissions management operating costs.

The result : you profit by eliminating your organic waste.
There is no risk. There is no cost.

Questions & Answers:

Q: Can the Solvent Fuel Processor handle mixed feedstock?
A: Yes. It's been run successfully on variable mixtures of alcohols, ketones, aromatics, acetates and
many other industrial solvents. There is no need to separate and control feed species into the system.

Q: How much power can you generate?
A: The specific answer depends on the solvent feed. However, in rough numbers, power generation will
be around 1.3 kW-hr/lb-solvent

Q: What about halogenated solvents?
A: Non-halogenated solvents are ultimately what must go into the Solvent Fuel Processing system.
However, depending on the concentration and species of halogenated contaminants in the solvent
feedstock, it can be removed on the front end before processing. The energy required for this removal
can be integrated into the main unit so that no additional operating costs are required. Contact AAI to
discuss specific applications with halogens.

Q: Are other gas configurations possible?
A: Yes. Given the number of products and by-products, there are many degrees of freedom within and
beyond the three outputs shown above. Contact AAI to discuss specific applications.

Q: What is the minimum system size?
A1: For power generation, at least 200 lb/hr of solvents are needed to generate power entirely from
solvents. At lower rates, auxiliary natural gas can be used to combine solvent conversion with additional
on-site power generation.

A2: For gas generation, there is no minimum size. However, economies of scale may make the capital
investment/lease costs prohibitive at very small solvent rates.
