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...

The lowest KR values in rupture discs KR values are used to determine the frictional flow loss in rupture discs. While the perception is that all rupture discs have high KR values, this company’s FAS (Forward Acting Scored) and PRO+ (Precision Reverse Operating) discs debunk this perception by offering the best flow characteristics available in a rupture disc. Having a lower KR value means that the...

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...
