Process Engineering & Design Professionals Should Ask “What If?”
Process engineering best practices should include asking the question “what if?” The process design seems fairly well oriented once the model has been made, the material balance and process flows are established, and the first pass at a general arrangement has been made. When sizing the vendor equipment, a process engineering consultant will work with [...]
Up Front Engineering is the Key to Successfully Managing Capital Projects
The end of the fiscal year is quickly approaching and capital budget plans for next year are due. Operations, Engineering and Maintenance have ideas of where funds can best be utilized, but day-to-day requirements only allow them to develop rough cost numbers and schedule durations based on “similar” projects from years ago. The project gets [...]
Marcellus Natural Gas Liquids
In the Western half of the Marcellus Shale Play, more than just methane flows from gas wells. In this region, hydrocarbons known as “natural gas liquids” (NGLs), are also present with the methane extracted from these wells. If harvested, these NGLs can be very valuable co-products of natural gas processing. The price of NGLs typically [...]
What Is Next For Frac Water Treatment
The management of Frac water from development of Marcellus shale wells has been subject to increasing scrutiny. The deeper Utica shale formation is as promising as the Marcellus formation, and will probably have similar management issues. Concerns about frac water include: Nature of constituents added for fracing Salinity of the frac water and impact of [...]
SILOXANE REMOVAL SYSTEM — VENTURE ENGINEERING ANNOUNCES NEW OFFERING TO LANDFILL AND DIGESTER GAS CUSTOMERS
Due to significant market demand from our landfill gas and digester gas (biogas) customer base, Venture has designed a completely modularized gas conditioning skid, primarily intended for siloxanes removal, with added gas conditioning benefits as described herein. Venture Engineering’s siloxanes removal system is based on a multitude of practical landfill gas processing experience and was [...]
High BTU Gas Plant — Landfill Gas, Coal Beds, and Digesters…
We get a lot of questions about landfill gas (LFG). What exactly is it? What can you do with it? Can my boiler use it? Do I have to clean it before I can use it? Should I make High BTU gas or Electricity with it? And so on, and so on. The following are [...]
Coal Fired Power Plants & CO2 Emissions
While there have been many arguments for and against man-made climate change, it is now clear that the balance of power shift from a Republican Presidency to a Democratic controlled Presidency and congress has certainly ended that debate for the foreseeable future. Now that the Democratic Party has taken control of both houses of Congress [...]
Marcellus Shale Play – Water Treatment Options Worth Considering
Centered in western Pennsylvania, the Marcellus stretches over 650 miles of the Appalachian Basin from West Virginia to the state of New York. Marcellus has been estimated to contain anywhere from 58 trillion to 500 trillion cubic feet of gas. A member of the Devonian black shales, Marcellus is categorized as a dual porosity reservoir, [...]
Benzene Reduction Strategies for Refineries
The US EPA’s most recent clean fuels regulations (MSAT II) will have significant impact on small refineries and/or refineries that are not located near the petrochemical beltway. The MSAT II regulations further reduce benzene to less than 0.62 vol-% (on an annual basis) in all U.S. gasoline by 2011. For most refiners, the reduction of [...]
