Update on PTDR-1000 Ongoing Waste To Energy Project in Ankleshwar, India

Waste To Energy, Waste Treatment No Comments »

Through PEAT’s India subsidiary, a Special Purpose Vehicle has been formed to support a PTDR-1000 plasma gasification waste-to-energy project within the Ankleshwar Industries Association to process a range of industrial waste and hazardous waste. A project site has been set aside by the local industrial development corporation and the official application to secure the land is expected later this year for the plasma gasification waste-to-energy project.

Further, the Environmental Clearance (EC) for the plasma gasification waste-to-energy project was granted in November 2009 and now the focus is on the process of securing the No Objection Certificate (NOC) from the Government of Gujarat.

The plasma gasification waste-to-energy project includes the utilization of a portion of the syngas produced to dewater an additional 15 metric tons of aqueous organic wastes (brining gate capacity to 45 metric tons per day).

PEAT Preparing Another PTDR-100 for Refinery Waste

Waste Treatment No Comments »

PEAT is finalizing the construction on another PTDR-100 Refinery Waste Treatment Plant for a client in China. This plasma gasification system, expected to be commissioned during the later part of June and early July, is being sought to treat refinery sludge and petrochemical waste.

The refinery waste product contains primarily water, and smaller amounts of non-aqueous liquids and solids, both organic and inorganic, are by-products of the refining and petrochemical industries. For example, a typical industrial waste stream from an oil refinery operation will contain about 80 percent-by-weight water, about 15 percent-by-weight oil, e.g., hydrocarbons and other non-aqueous liquids, and about 5 percent-by-weight solids. Due to environmental regulations, this industrial waste stream poses significant disposal problems for the oil refineries.

The PTDR waste-to-energy system will convert via plasma gasification approximately 50 kilograms/hr (110 lbs) of this refinery waste into syngas estimated to be almost 600,000 BTU/hr (150,000 kCal/hr).

GHG Emissions

Emissions 1 Comment »

A lot has been reported regarding the EPA going after GHG emissions, specifically CO2. Initially the thought was the EPA would just focus on the largest facilities (ones that release more than 25,000 tons per year), but it appears that this mandate may be expanded to other industries. Further while it appears this threshold may be increased (between 75-100,000 tpy – the EPA still intends to regulate at the 25,000 ton number – it just may give more time to those facilities to around 2013 possibly.

One in particular is the refineries, where the EPA may propose a new NSPS this summer that is expected to include GHG emissions.

One way a refinery can offset these emissions is using a PTDR system for industrial waste treatment whereabouts it could potentially reducing the carbon footprint associated with the industrial waste stream disposal process.

Carbon footprint reductions could be realized in the following areas:

  • Elimination of transportation as waste would no longer travel hundreds of miles for treatment and/or storage leading to reductions in carbon dioxide (CO2), nitrous oxide (NOx) and methane (CH4) emissions
  • Alternative waste-to-energy processing as waste would not longer be landfilled or incinerated leading to reductions in carbon dioxide, nitrous oxide and methane emissions

Further, when the syngas is consumed in gas engines as a fuel source (i.e. waste to energy), the emissions of the resulting flue gases are significantly lower than those generated by other methods such as landfilling and/or incineration.

PTDR facilities offer distinct advantages over conventional incinerator systems used for the thermal destruction of waste:

  • High operating and uniform temperatures preventing the formation of furans and dioxins (no “cold spots” in a PTDR)
  • A controlled processing atmosphere
  • No fly or bottom ash generated, requiring further treatment and disposal
  • A PTDR system produces a gas volume that is significantly less than the total combustion gas produced by an incinerator processing the same amount of waste
  • The minimization of outside air used in the sealed pyrolysis process reduces the potential for emission control problems, particularly those associated with nitrous oxides and other pollutants.
