Sulfur dioxide from a simulated flue gas was solely absorbed in our experimental  set  up. The  employed  range  of  2000 ppm to  9600  ppm  of  SO2 was  attempted  separately with industrial ratios of flue gas to absorbent flow rates in each case.  Regardless  of  the  SO2 concentration,  the  selective absorption  was successfully  reported  in  all  these  trials,  without  touching  other  components  in  the  flue  gas such as CO2 . The SO2 concentration of the treated flue gas leaving the absorbent column  in  these  series  of  experiments  is  always  well  below  environmental standards of 500 ppm. It  was  observed  that desulfurization  of  flue  gas  for  our  solvent  pilot  operates  at  the  maximum performance at PH of 6, SO2 concentration of 4200 ppm, desorption temperature of  110°C,  and  the  gas  to liquid  ratio  of  375. In  this  study,  we  employed  and simulated the absorption by a unique absorbent, ASH-S100, caused an excellent selective  absorption  of  SO2 from  flue  gas.  We showed that at an optimum condition, ASH-S100 can reduce the amount of SO2 in flue gas from 2400 ppm down to about 270 ppm.

Due  to  the  ever-increasing  cost  of  energy  and  more  stringent  pollution  standards  for atmospheric  emissions,  it  is  desirable  to  improve  absorption  processes  for  the  removal  of carbon dioxide from flue gas. The research needs have been reviewed for CO2 capture from flue gas by aqueous absorption/stripping. A close-looped absorption/stripping pilot plant with 15 cm ID columns was used to capture CO2  using a new blended amine (ASH-S200) solution. Both the absorber and stripper contained 1.5 m of packing.  Various absorber temperature, gas and liquid rates and lean CO2 loadings were tested.  The operating parameter used in this study consisted of the following: (1) the gas flow  rate;  (2)  CO2  mole  fraction  in  feed  gas;  (3)  liquid  flow  rate;  and  (4)  absorber temperature. With the flue gas flow rate of 3 m3/hr, CO2 mole fraction of 10 %, Liquid flow rate of 300ml/min and absorber temperature of 60 °C maximum capture efficiency of CO2was founded, with  the  value  of  95.55%. The percentage contribution of each parameter was also determined. The flue gas flow rate is the most influential parameter for maximum absorption of CO2, and its value of percentage contribution is up to 72.22%. Also mass transfer rate and CO2 solubility obtained  in  this  work  and  then  compared  to  MEA  solvent  data  in  literature values as a base solvent.

The pilot plant for these processes indicates in below figure




Catalytic Cracking Process to Treat Vacuum Residue and Vacuum Gas Oil into light hydrocarbons


Catalytic cracking of  petroleum to produce  gasoline began in about  1912.  The early pioneering  work  w a s   carried  out by Eugene Houdry .  Modern fluid  catalytic cracking (FCC)  was  conceived at Exxon and commercially developed in about  1940 using  amorphous  catalysts. Fluid  catalysts  are  small  spherical particles ranging  from  40 to  150μm   in  diameter  with  acid sites capable of cracking  large  petroleum  molecules to  products  boiling  in  the gasoline  range.    One  advantage  of  the  FCC  process is the absence of  the diffusion limitations present  in conventional gas oil cracking due to the small size of  the catalyst  particle.  Since 1964 virtually  all  catalysts contain faujasite,  a stable, large pore,  Y- type  zeolite dispersed in a silica/alumina matrix.  The catalytic  aspects  of  contemporary FCC  processes  have been  reviewed by  Venuto and Habib   41 , Gates,  Katzer.  andSchuit , Magee and Blazek , and Magee .   A more recent update of refinery trends has been made available by Blazek. is sprayed into the riser where  it mixes  with  a  hot  ( 700°C)     catalyst to produce  a reaction  temperature  of  about  550°C.    The vaporization  and cracking of  the oil provide a threefold  volume expansion.   This expansion plus the introduction  of  steam provides a gas flow  that  transports the catalyst  and  oil/gasoline/gas mixture up the riser into a  reactor  zone.   A  series of  cyclones  with steam  stripping disengages the catalyst from the petroleum  products.   The catalyst is then transported to the regenerator  where %  1% carbon  and a small amount of  hydrogen  as hydrocarbon  on the catalyst is burned  off.   The reactions  shown below,  which occur in the regenerator, are exothermic  and produce temperatures of about  700°C  and  a  %  20% steam environment.   Most  of  the steam comes from  burning  hydrogen  derived  from coke or entrained hydrocarbons.




With notice to above explanations we using of novel catalyst ASH-C200 in a fixed bed as modified process in a pilot plant that indicated .It  is the only technology that has been demonstrated to operate on a wide variety of feedstocks, ranging from refining residues to coal, and a mixture of oil and coal. Besides vacuum residues, other feedstocks, such as de-sphalter bottoms, visbroken vacuum residues and thermal tars have been tested in either the Bottrop or Scholven units in iran. Additionally, unconventional feeds such as used lubricant oils, cutting oils, residues from degreasers, used chlorinated solvents, paint sludges, transformer oils (PCBs), spent hydrotreating catalysts, spent activated carbons and recycled plastics have been successfully processed.

Catalytic Cracking Process to converting of polymers and mixed polymers into middle distillate products

Saving and managing fossil energy like crude oil, natural gas or coals have a giant effect  on  the  rate  of  economic  growth  and  without  that  this  rate  would  become unsustainable.  Thus  humans  have  to  rely  on  alternate-  renewable  energy  sources  as biomass,  hydropower,  geothermal  energy,  wind  energy,  solar  energy,  nuclear  energy and so on. On the other hand, waste management might be a strong solution. As modern life  and  cities  growth  every  day  the  amount  of  all  kinds  of  commodities,  which indirectly generate waste. Plastics waste production has been one of the highest amount of wastes to be produced and that due to their versatility and low cost. By considering plastics small life period in use there are vast plastic wastes in the environment, which results  in  serious  environmental  problems.  As  disposal  of  waste  plastics  is  increasing there  is  considerable  demand  for  land  filling.  Advanced  research  in  green  chemistry could  yield  biodegradable/green  polymers  but  at  this  period  of  time  it  is  limited  to substituting the non-biodegradable plastics in variance applications. As degradation of plastics  become  more  standard and developed they can  be used to figure out the best formulations of materials for using in the applications of interest by their performance.. Among  the  alternatives  available  for  now  source  reduction,  reuse,  recycling,  and recovery  of  the  inherent  energy  value  through  waste-to-energy  incineration  and processed fuel applications can be mentioned. Liquid fuel productions would be a giant leap and fantastic alternative as the calorific value of plastics [1]. Pyrolysis is generally defined as the controlled burning or heating of a material in the absence of oxygen. Pyrolysis alongside cracking are two major methods of processing waste plastics into fuels such as Poly olefins. These methods may be categorized as the tertiary  mode  of  recycling.  Using  these  types  of  recycling  is  acceptable  especially  in case of poly olefins As their further use in primary recycling (conversion into products similar  in  nature  to  the  original  product)  and  secondary  recycling  (conversion  into products  of  different  shape  for  less  demanding  products)  is  impossible.  Furthermore, pyrolysis may reduce the landfill required for wastes. The catalysts that is being used should be obtainable on commercial scale and also regenerated back in the end of process, The novel catalyst (ASH-C100) used in ASH company would be cheaper and it also satisfy the mentioned requirements and this catalyst(ASH-C100) suitable for Fixed bed reactors, FCC reactors and Semi-batch reactors , also pilot plant of this process indicates in below figures.





Managing Plastic Wastes has turned to be one of crucial problems, keeping in mind that liquid fuels can be produced from such materials. The chosen catalyst is a novel catalyst named ASH-C100, which is made and developed in Research Center of  AbadgaranArvandShimi.  The  catalyst  categorizes  in acidic catalyst group, which are suitable for cracking of heavy hydrocarbons.Three  samples  consisting   high-density  polyethylene,   low-density  polyethylene, polypropylene,  polystyrene,  polyvinyl  chloride  and  polyethylene  terephthalate  were picked  and  the  setup  was  designed  for  determining  the  effects  of  temperature  and catalyst/polymer  ration  on  conversion  of  these  samples  into  liquid  fuels, also catalysts ASH-C101 to ASH-C107 compatible for converting single polymers (HDPE, LDPE, PP, Polyolefins, PS, PVC and PET).

Recycling material is one of the important environmental agenda defined in 3R. Instead of simply reusing the material as it is, successful chemical reusing is a more effective way reducing the use of natural resources and environmental damage incurred thereof. We would like to draw your attention to our new process and a pertinent effective plant which successfully converts plastic wastes into wax-free hydrocarbon such as naphtha and diesel oil.




Special features

[1] Possible to crack mixture of plastics (PP/PE/PS) which are difficult for mechanical recycle

Small impurities such as sand, dirt and metal are processable.

[2] 100kg waste plastics can be converted into max. 100L cracked oil
(up to input materials) Yield is 86% in case of mixture of PP, PE, PS

[3] No solidification even under low temperature (WAX-FREE)

[4]  Low residual chlorine (below 100ppm), even if 10% of PVC is mixed

[5] Simple oil-converting process; continuous operation for max. 5 days

[7] Low running cost (using cheap catalyst ASH-C100)


Comparison with ordinary waste-to-fuel method



Property table of cracked oil using RTP







Q.1 Features of this plant?
Our new breakthrough oil conversion plant is quite different from the ordinary one. We call this “Continuous waste plastic catalytic cracking oil production” plant. It can operate continuously until the activity of catalyst decreases the activity can be reactivated by burning off the deposited coke. With its unique system, high performance with low production cost is achieved. Our plant size is smaller than ordinary types.

Q.2 processing capacity?
Processing ability: max. 4,800kg/day (RTP-200),max. 9,600kg/day (RTP-400)
Maximum operating time: 5 days straight without catalyst exchange
Residue clean up and catalyst exchange: every 5 days
(Possible for 1-month non-stop operation at a maximumby adopting a new way of continuous catalyst exchange.)

Q3. How does it process? 
(1) Crushed plastics (less than 15 mm size) are fed into the hopper on the top of the plant.
(2) Plastics are sent to the reactor through the vertical pipes controlled by several valves without melting.
(3) Plastics are rapidly heated to 400-450Ž by catalyst for gasification.
(4) Cracked gas goes to the condensers and turned into naphtha,diesel oil and heavy oil. Those are stored in separate tanks.
(5) Off gas can be used as combustion fuel for heating the reactor.

Q.4 What’s different from the popular method?
There are more than 20 makers of waste-plastics-to-oil conversion plant in Japan. Most of them are non-catalyst batch system. The batch system has low thermal efficiency, because the reactor should be cooled off in every batch for safety reasons.
Unlike the batch system, our new method allows 5 days continuous operation with high yield of cracked oil.

Q.5 Safety and environmental issue?
(1) Chlorine gas from PVC (Polyvinyl Chlorine) can be neutralized and eliminated by a neutralizer, thus the chlorine density in the cracked oil is controlled below 100 ppm.
(2) Off gas and its odor does not influence the atmosphere because off-gas is used as combustion fuel for heating the reactor. (3) No special considerations are required for reducing noise and vibration generated from the plant because of its structural arrangement.
(4) Cooling water doesn’t get contaminated since it is used cyclicality only, so it can be discharged directly to the sewers without any treatment.
(6) The hot air from the blower is not contaminated and can be released directly into the atmosphere.

Feedstock blends of VGO and deasphalted oil, coker gas oils, and residue hydroprocessing products can also be effectively upgraded to further increase net fuel oil conversion.

Unmatched experience combined with continuous innovation


The ASH FCC process with using catalyst ASH-C200 can help you achieve your refining and petrochemical objectives by converting straight-run atmospheric gas oils, vacuum gas oils, certain atmospheric residues and heavy stocks recovered from other refinery operations into high-octane gasoline, light fuel oils and olefin-rich light gases like propylene for petrochemical use and butenes needed for the alkylation process.

ASH first developed FCC technology in the 1940s, but we continue to evolve this technology focusing on continuous process-design innovation. Many of today’s state-of-the-art FCC units utilize advanced technologies to enhance catalytic cracking and reduce thermal cracking for significantly higher yields of desired products.

Technology: Upstream

ASH-C300 is a novel, catalytic process that offers the disruptive ability to upgrade heavy-sour crude oil, providing an increase in value as high as 5% -30%. ASH-C300 is an innovative leap in upgrading technology that operates at much lower costs than existing upgrading processes. Because ASH-C300 has a small footprint, oil producers can field upgrade heavy-sour oil while drastically improving their economics. ASH-C300 has been proven to be effective on many heavy-sour crude oils as well as bitumen and coal liquefaction product.

Increase API gravity. Increasing API gravity can increase the value of a crude by 5% to 30%. For example, raising oil sands bitumen API from 10 to 20 eliminates the need for diluent and can provide a revenue boost of $10-$20/bbl. Other heavy crudes will see benefits closer to the 5%-10% range.

Sulfur Reduction. Sulfur levels above 1% get discounted 2%-5% depending on many factors including sulfur level. ASH-C300  can target and achieve specific sulfur levels depending on the desired quality of crude oil, increasing the overall value of the oil.

TAN Reduction. For heavy-sour feeds that have naphthenic acid levels in the 3%-4% range, producers are forced to sell their crude at a discounted rate. Removing TAN not only increases value but allows crudes to be sold to a larger portion of the refinery market, not just complex refineries that are able to process high TAN.

Metals and nitrogen reduction. Crude with high metals and nitrogen content is discounted along with other entrained contaminants. While the life of the ASH-C300 catalyst is not reduced by contact with these heteroatoms, metals and nitrogen have an adverse effect on other catalytic processes downstream. ASH-C300 treated crude oil will allow the refiners to achieve longer catalyst life and reduced process intensity, thus increasing the value of the crude oil.
