Yesterday, U.S. District Court judge Paul Friedman denied a legal motion by the U.S. Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) that would have prevented environmental groups from challenging EPA's stay of proposed changes to the Maximum Achievable Control Technology (MACT) standard for industrial boilers. While the decision was procedural, it suggests to ACC that the stay is...

Steam-assisted, gravity-drainage (SAGD) operations employ large tanks that vent flammable and sometimes toxic gases. Safety and environmental concerns often require engineers to design vapor-recovery units (VRUs) to collect these gases and redirect them to a useful location — frequently for use as a fuel gas in a steam-generation system. When choosing a VRU setup for an SAGD facility, the two most...

For years it has been the common practice to treat process water with various chemistries to prevent scale, corrosion and microbiologicals. However, as regulatory issues tighten, water scarcity becomes a growing concern and the cost of treatment chemicals increases, chemical processors are finding that stringent treatment chemicals are not the only answer. Instead, they’re relying upon a multi-prong...

Almost by definition, chemical engineering is a “green” discipline today, as it so often involves efforts to optimize chemical processes in order to reduce the amount of energy and raw materials that are used and the amount of waste that is generated. Today everybody “talks green” but in a lot of cases engineers are the most qualified people to provide the tools required to make...

Last year, the U.S. Environmental Protection Agency (EPA;Washington, D.C.; www.epa.gov) proposed new emissions standards for hazardous air pollutants (HAP) emitted by industrial boilers and solid-waste incinerators (CISWI) based on the performance of the maximum achievable control technology (MACT). The so-called “boiler MACT” final rules were signed by the EPA Administrator on February 21...

The realization that our natural resources are not endless, and that we need to focus on sustainability is driving technology and its supporting funds toward new choices. In the chemical process industries (CPI), engineers are looking for alternatives to the traditional fossil-fuel-based chemistries, and are developing innovative bio-based routes to meet our needs. There is much evidence of this shift to a...

In the emerging and ever-expanding areas of bioprocessing, where maintaining hygienic designs and practices is of paramount importance, and semiconductor manufacturing, which has its own stringent purity requirements, there is a need to standardize the essential codes and standards that are available. The goal is to consistently achieve process systems that meet the highly refined cleanliness and...

NewAge Industries (Southampton, Pa.; www.newageindustries.com) has completed the installation of a one-megawatt rooftop solar-panel system, which supplies half of the plastic tubing manufacturer's energy needs. The project started last summer with upgrades to NewAge Industries’ roof. Solar panels now cover three-quarters of the rooftop on the 244,000-ft2 building located in Southampton, Bucks County...

Combustion provides heat for many industrial processes and accounts for over 80% of the power used by turbines to generate electricity. Over the past several decades, regulatory action and concerns over environmental air pollutants, such as oxides of nitrogen (NOx), have pushed industrial process designers to develop burners that lower pollutant emissions and prompted manufacturers to switch to...

LEAN Chemical Manufacturing There has been a great deal of new activity around so-called lean thinking or the lean enterprise lately, even though the practical application has been going on since the early 1900s. It was started by Henry Ford, and followed on by Edwards Deming and Taiichi Ohno. These three were relentless foes against waste. If the chemical process industries (CPI) were to implement lean to...
