A next-generation, carbon-enhanced membrane-bioreactor (MBR) system improves treatment of industrial wastewater with high organic content and containing compounds that resist microbial breakdown. The system allows economic reuse of wastewater or discharge to meet stringent environmental standards. The new MBR, dubbed EcoRight, will be commercially available in early 2011. First envisioned by Saudi Aramco...

The Commonwealth Scientific and Industrial Research Organization (CSIRO; Melbourne, Australia; is partnering with China United Coalbed Methane Corp. (CUCBM; on a A$10 million joint demonstration project that will store 2,000 metric tons (m.t.) of carbon dioxide underground in the Shanxi Province and extract methane for use as an energy source. The project will focus on...

As environmental awareness receives renewed focus in the government, the public and industry, it appears that higher standards will be applied to processors to achieve even higher oxides-of-nitrogen (NOx) removal than in the past. And since selective catalytic reduction (SCR) has been proven to be one of the most efficient systems for NOx removal from high output sources, such as coal-fired power plants...

With bio-based chemical production growing, and several newer companies ready to enter commercial production, indications are that biologically derived chemicals will be an increasing force in the petrochemicals market. But bio-based chemical producers must confront the bottom-line requirements of product performance and cost, rather than riding their products’ environmental benefits. Susan Sun...
June 17, 2010
BASF SE (Ludwigshafen, Germany; and RTI International (Research Triangle Park, N.C.;, are joining forces to develop a new, exceptionally cost-effective technology to capture carbon dioxide  from waste gases emitted by coal-fired power plants and other industrial sources. The development project is sponsored by a $2-million cooperative agreement from the U.S. Dept. of Energy...
June 11, 2010
U.S. Energy Secretary Steven Chu today announced that three projects have been selected to receive up to $612 million from the American Recovery and Reinvestment Act — matched by $368 million in private funding — to demonstrate large-scale carbon capture and storage (CCS) from industrial sources. The projects — located in Texas, Illinois, and Louisiana — were initially selected in...$1-billion-for-industrial-CCS-_5761.html

Question:  What is driving the trend toward increased water reuse and how is membrane technology addressing this? Furthermore, what does the future hold for water reuse? Answer: Meeting water demands and ensuring a plentiful supply of water for future generations is a top-of-mind issue for the water industry today. Adequate, safe and accessible water supplies are essential to sustaining life and...

Non-chemical methods for conditioning water for use in cooling towers and boilers have been investigated, marketed and installed for over 100 years. In light of the recent incentives to “go green,” these methods offer engineers, operators and owners the option of replacing corrosive, toxic chemicals with physical or mechanical processes that claim to produce the same or superior results to...

Question: Stricter wastewater regulatory environments and water availability continue to drive water reuse and recycle in the chemical and petrochemical industries globally.  What should companies consider when evaluating water reuse as part of the manufacturing and wastewater process? Answer: While reusing wastewater can be an economical alternative to internal or external fresh water supplies, there...

A little over one month ago, the United Nations Framework Convention on Climate Change (UNFCCC) received national pledges from 55 countries, to cut and limit greenhouse gas (GHG) emissions. Included in the pledges was a commitment from the U.S. to reduce its GHG emissions in the range of 17% from 2005 levels by 2020. The non-binding target came with a disclaimer, however, that hinges on an uncertainty for...

As 2009 came to a close, the U.S. crossed a key milestone in the path toward regulating greenhouse gas (GHG) emissions. Nearly 10,000 facilities (Figures 1 and 2) — a significant portion of them in the chemical process industries (CPI) — became subject to the U.S. Environmental Protection Agency’s (EPA;; Washington D.C.) Final Mandatory Greenhouse Gases Reporting Rule...

The delayed coking process is a fundamental part of the petroleum refining and petrochemical industries, and is among the main technical means for transforming inexpensive heavy oil into more valuable, light-oil products. Delayed coking units are common in petroleum refineries, and the process has been developed significantly as a heavy oil processing method in many countries, including China and the U.S...

This article describes an algorithm that end users can use to develop a program on a personal computer to assess the technical and economic feasibility of installing a variable frequency drive (VFD) on centrifugal pumps. This simple algorithm serves a variety of useful functions, helping engineers to carry out the following functions: Check the technical feasibility and evaluate whether or not it is...

Typical wastewater-treatment plants (WWTP) — both industrial and municipal — consume large amounts of energy, which can represent 50% or more of the facility’s variable operating and maintenance costs. Most employ biological processes that rely on energy-intensive aeration systems whose energy consumption is approximately 0.5 kWh per m3 of effluent treated. This article discusses a...
