Biofuels
COSTELLO a leader in cutting edge alternative and renewable energy plant design. As Consulting Engineers, we are in the forefront of renewable and alternative energies. We focus our attention on design services in support of alternative energy projects, including biodiesel, biomass gasification and biogas production and purification. We offer services from feasibility studies to the full scale batch or continuous plant design.
Biodiesel
Plant design and Construction
Costello provides engineering design and construction supervision for our second-generation biodiesel plant technology known as Bioflexplant SM It handles free fatty acids with a solid catalyzed esterification pretreatment unit and also includes degumming. Free fatty acids up to 15% can be handlled.....
Biogas
From anaerobic digestor to gensset or pipeline
Costello provides engineering design of biogas plants that utilize, single stage compression, multi stage compression, amine units, PSA units, siloxane removal, H2S removal and dehydration. Costello has provided engineering services for the largest dairy cattle manure digestion to pipeline grade biomethane in the world..
Gasification and Pyrolysis
Syngas a building block for other fuels
Whether you are using biomass, municipal solid waste, tires, plastics or construction debris, Costello can help you produce clean syngas for processing into methanol, ethanol, Fisher-Tropsch synthetic petroleum, dimethyl ether or gasoline from methanol.
Green Diesel
Clean fuels that bend with petro diesel
Green diesel is produced either from hydrotreating or plant oils or animal fats. Green diesel is chemically different from biodiesel. Green diesel has chemical properties identical to petroleum diesel. It is typically water white in color.
Fischer-Tropsch SM
For synthetic diesel, naphtha and wax
Costello offers the Fischer-Tropsch process which can produce fuel out of syngas. It also offers a way to recover "stranded" natural gas (resources that would be uneconomical to transport in gaseous form). Synthetic diesel from biomass qualifies for the $1.00 per gallon Federal tax rebate whereas synthetic diesel from coal, coal bed methane and natural gas do not.
COPureSM
For high purity carbon monoxide
We also provide front-end engineering design packages for our proprietary biosyngas and syngas purification technology known as COPureSM. This technology can selectively remove carbon monoxide from, biosyngas, syngas and high nitrogen syngas. Secondly hydrogen can be recovered by PSA and recombined with CO in a specific ratio of hydrogen to carbon monoxide.
