of contamin.a, hts. The HAV_E technology was patented because of its design ba. sed upon...soii.':
vapor recycling, heap cont~guratio, n, and furnace chamber design. The contamtnated, s;o.il is '
maintained in a stationary heap pde and th.e. soil heating is achieved by placin.g hot atr
and vapor extraction ducts ~thtn the soil pde. This technology ha.s the potential for providing.

HAVE Process Description
The HAVE system is a transportable system capable of ex-situ remediaUon of '
hydrocarbon contam,~ants in soils, including gasoline, diesel, jet fuels, and heavy oils. As'witl~
other ex-situ remediations, the contaminated soil needs to be excavated prior to treatmenL '.
The excavated soil is then built into a pile containing the hot air injecUon and vapor extraction''
ducts for circulating hot .air into the pile. The sotl pile is covered and sealed with a thin sheet o
structurally strong and high temperature resistant fabric, f

gasoline pile was 132° F after three days of operation, and 150° F after 14 days of operation-
for the mixed fuel soil pile. Polyethylene membrane sheeting was used to cover the treatment
cells for both of these runs.
The gasoline pile was ?.mediated within a period of thr.e.e days.to non-detectable .levels ..
from the initial peak concentration of 160 ppm of TPH as gas,.ohne. Th~s test provid.ed . .:..
oreliminary data useful in tuning the computer model for predicting temperatures,_ att ve!ocmes,.
· -~nd contaminant concentration distributions within the pile. Based on these results an='.
~cioated comi3uter modeling requirements, the test plan and monitoring set-up were
modit~ed for tes~ No. 2. The modifications included the installation of vapor monitonng p?rtSln -
each of the five vapor dist~bution ducts, increasing the number of temperature ,sens~o,rs. tm.m:.. :. '.'.
18 to 50, and the pre.fab.ric~..tion of an array of the .n:nocouples to be located at 4 to 5 spacing
between the 4" hot a~r injection ducts. The monitonng of treatment cell temperatures were
TM
increased from 2 per day to 4 per day.
The m..ixed fuel soil pile was treated in the original cell configuration with the above--te~t'
plan modifications. Treatment over a pedod of ..14 days resulted in the removal of about 4,000
pounds of hydrocarbons based upon the reduction i.n TPI:I...can.ce. ntratio.~..,_ H .o~..ver, the soil
was not remediated to regulatory standards due to t~e relauvely tow volatility ot me
contaminants and the Iow soil temperature. Soil heating ~vas slow, reaching a temperature of
200' F at the first level injection manifold after about three days. Farther away from the
manifold soil temperatures ranged from 160' F to 120* F. The temperatures at the first level
manifold increased to 400' F after eight days, and alter a brief excursion to 600' F returned
gradually to 480' F at the end of 14 days. The soil temperature away from the manifold ·
reached 200' F at a distance of four feet and 150' F at a distance of 20 feet at the end of 14
days. Soils in levels 2, 3, and 4 reached a maximum temperature of 1~0' F.
Computer simulation of air velocity dtsth~uttons indicated that some of the'hot a;~ _.:. '"":
injected was bypassing the soil and was _flowing .di~.. ?.to.the balloon..area .b.e._ _tWe~___~?~..
and the membrane sheeting. It was not feasible to ettecave~y mcrease, me so, tempera?
beyond 200' F with this type of treatment cell design because the ma3~mum temperature me:
polyethylene membrane could wlth~d was about 200' F.
Computer modeling and simulations indicated that the treatment cell as co,ill, lured f~'
tests Nos. 1 and 2, and the operation of the HAVE system resulted in litl~e or no
heat and mass transfer from the soil. Conducf~e heat transf~ from the interstitial alt In the
balloon area was found to be a significant contributor to the overal~ remedlat~on efficiency
the system. Therefore, mod~cat~ons were made to the HAVE system design, test monitoring
plan, and operation for test Nos. 3, 4, and 5.
Remedlation of Heavy Oil and Mixed Fuel Contaminated Soils at High Temperatures
The .cell construction was modified for the treatment of the heavy oil and mixed fuel
contaminated soils, and a typical section of the constructed pile Is shown in Figure $. The ~.
pile was constructed somewhat shallower than before, and the 4" hot air injection ducts. Were
exposed at the end to allow more mr flow to the section of the pile farthest from the rnam
injection ducts. Temperature sensors were installed in the injection ducts at all layers, both
close to the main 12" ducts and at the opposite end in the 4" ducts. Acrylic-fiberglass '"'
sheeting was used to cover the soil so as to allow higher balloon gas temperatures.

The results of the economic analysis are desc~bed in Table 3. AS shown in.~· teblei.:'
the economic analysis accounts for various Cost categories comprising' of: regulatorY and.
compliance, equipment rental or leases, startup, labor, materials, utilities, and equipment repair'
and replacement. The treatment costs for remediation project sizes ranging from 750 to 9,000 ~ ~.
cubic yards were found to vary from $64.05 down to $35.54 per cubiC yard,-respectivelY. The
treatment costs for project sizes of 9,000 cubic yards or greater are c0mpe,fJtive tO.,'~rthOSe of'-'
conventional bioremediatton technologic. For smaller project sizes, the HAVEtechno.!ogy~.'. '.
though not as cost effective as bioremed~ations, provides a speedy method of remediation. ' '.'
CONCI..USIONS ';.. ".,
Field demonstration studies were conducted on welHnstrumented s0il treatment
determine the effectiveness of the HAVE system for the remediation of.hydrocafl3On"..
contaminated soils. Computer modeling studies were performed concurmntiYto OPtimize the
performance of the system. Test runs were conducted on soils contaminated With gaSoline,:~ .~.~
and soils contaminated with high boiling petroleum fractions such a~ he~/011 art~l lubricating-
oils. The HAVE system was effective in remediating gasoline co--ted '~oils-at 10w'::...
temperatures. For soils contaminated with diesel and fuel oils and higher'boiling fractions, IoW
temperature operation was not effective in reducing the contaminant aoncentrations to the
acceptable levels. Computer s'm~ulations conducted on the ortglnal HAVE design showed that '
the reason for the Iow soil temperature (150° F) was due to short cin:uiling of injecta<l air into
the balloons. Therefore, to achieve the higher soil temperatures needed to remedlate the
higher boiling point contaminants, the system design had to be modified.
The HAVE system design and treatment call construction ware mco'ifled to,obtain.'~ a,,-.:..
higher temperature dist~ution in the soil for tests conducted to mmedlete heavy otl.?l mixed':..
fuel contaminated soil pile~. The enhanced design allowed higher ~ ranging .' . '...-'
between 212' F and 410' F to be maintained within the soil plle. Two.~pamte:~ ~m~ ~mve. ' r
· shown that soils containing concentrations of about 5,000 ppm of high bolling petroleum .-....
hydroca~ons ware remediated with 96A% removal efficiency.
Soil temperature: moisture, clay content, and contaminant vapor pressures are some of
the key variables that must be properly addressed in designing a HAVE remedi~...Uon
contaminen~ If these variab~ are effectively considered In its design and operaOon to
spactl~ soil mmadiation needs.
Rnally, economic analysis conducted for vm~ous remedlation I~O]aCt sizes ranging from
750 to 9,000 cubic yards showed that the treatment costs vary from $64.05 down to $36.54
per cubic yard, respectively. The HAVE system appears, to be co~t competitive with
conventional bloremecl'mtion methods when the remediation pro]act size Is 9,000 cubic yen:Is or
larger.
