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; http://www.epa.gov; 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...

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...

Last month, a total of 17,722 visitors and 995 exhibitors attended WEFTEC.09, the Water Environment Federation’s (WEF) 82nd annual technical exhibition and conference held in Orlando, Fla. Particularly in this time of economic concerns, the strong showing reinforces the importance of water — its availability, treatment and reuse — in both industrial and municipal sectors. At the show...

Alstom (Paris, France; www.power.alstom.com) and major Canadian power company TransAlta —along with their partners in the governments of Canada and Alberta and Capital Power, an independent power producer— have created a partnership to construct a large-scale carbon dioxide capture and storage (CCS) demonstration facility at one of TransAlta’s coal-fired generating stations in Canada. The...

On October 2, U.S. Energy Secretary Steven Chu announced the first round of funding from $1.4 billion from the American Recovery and Reinvestment Act for the selection of 12 projects that will capture carbon dioxide from industrial sources for storage or beneficial use. The first phase of these projects will include $21.6 million in Recovery Act funding and $22.5 million in private funding for a total...

In more and more locations, the availability of fresh water resources is limited and water reuse is becoming increasingly important. For many industrial applications, the availability of water is essentially a “license to operate”. A large component of the water consumption in many chemical process industries (CPI) is high- and low-pressure boiler water. As such, reusing cooling water blowdown...

Substantial technological advances to meet the growing regulatory scrutiny of a wide variety of pollutants have taken place over the past 50 years. In the last few years, the increased complexity in regulations in developed countries has been even more accelerated, challenging the chemical process industries (CPI) and their suppliers of air-monitoring equipment to reach new heights. In addition, developing...
