Unwelcome oxygen Tank blanketing is the process of filling the headspace in storage vessels and reactors with an inert gas to prevent its contents from exploding, degrading or polymerizing and to protect equipment from corrosion. A blanketing system is normally designed such that it operates under higher than atmospheric pressures, therefore preventing outside air from entering the vessel. As oxygen and moisture in the air can be undesired in numerous processes and applications, blanketing is done in a wide range of industries, varying from (petro)chemical to food and beverage, pharmaceutical to pure water.
Choosing the Right Emissions Control Option
Determining the most economical option to control airborne emissions during chemical process operations presents several unique challenges. As with any add-on control system, the goal is to minimize the annualized total costs while maintaining proper operation. In this white paper, learn the different options that are available and which ones fit your process the best.

Closed System Technology Drives the Trend Toward Safer, More Cost-Efficient Chemical Dispensing
In dozens of industries and in millions of applications around the world, dangerous chemicals are transferred from their original shipping containers into smaller jugs or buckets or applied to other end-use processes. Historically, the predominant dispensing method in many of these applications has been through an open system where the liquid is poured out of the container. With a poured system, the container is often flipped on its side and the liquid is poured into a secondary container.
The user then just carries the bucket to wherever it needs to go. A mental image of this technique quickly reveals its potential dangers and inefficiencies.

Case Study: RTOs Leave Nothing to HAPpenstance
In September 1998 the EPA promulgated a ruling in 40 CFR, imposing strict new standards to reduce emissions of toxic air pollutants from the manufacture of pharmaceutical products, including prescription and over-the-counter drugs. The agencys rule was intended to reduce emissions of a number of air toxics and hazardous air pollutants (HAPs), including methylene chloride, methanol, toluene and HCI. It was estimated at the time that the ruling would reduce air toxins annually by approximately 24,000 tons or 65 percent from contemporaneous levels. The affected pharmaceutical manufacturing processes included chemical synthesis (drawing a drugs active ingredient) and chemical formulation (producing a drug in its final form).

Special Report: Chemical Industry Sees Green
For years the industry has been talking green. But what real strides have been made? Will a Presidential Executive Order compel the industry to speed up efforts to actually go green? While pollution prevention was the original goal of green chemistry, todays efforts promise to have a substantial economic impact. This Special Report will bring you up to speed on fruitful efforts to go green including an update on the growing interest in bio-based feedstocks.
Environmental Health and Safety Compliance in Biotech Companies: Common Deficiencies Encountered During Audits
Environmental health and safety (EH&S) compliance programs for companies that house laboratories are complex and not easily maintained. Even the most basic plan involves keeping a variety of permits up-to-date, performing regular employee training, conducting inspections, complying with a myriad of chemical storage and handling requirements, and keeping a number of contingency plans current and complete. This white paper identifies the most common pitfalls and four simple steps to keeping your EH&S program current.

Implementing Foundation fieldbus
This white paper provides some insight into the process for safely implementing Foundation fieldbus in an area of your facility that has a hazardous classification.
Guidance note for environmental safety instrumented systems
Safety Instrumented Systems (SIS) are designed to monitor the process and control outputs to prevent or mitigate hazardous events. The design process strives for inherent safety, which is enhanced by applying multiple independent safety layers. Learn how to prevent accidents with prevention layers and minimise the consequences with mitigation layers.

Chemical Hazard Communication
Under the provisions of the Hazard Communication Standard,
employers are responsible for informing employees of the
hazards and the identities of workplace chemicals to which
they are exposed.
The Regional Transport of Ozone
EPA tracks emissions of six principal air pollutants - carbon monoxide, lead, nitrogen oxides, particulate matter, sulfur dioxide, and volatile organic compounds. All have decreased significantly since passage of the Clean Air Act in 1970 - except for nitrogen oxides.
Hazard Communication Guidelines for Compliance
OSHAs Hazard Communication Standard (HCS) is based on a simple conceptthat employees have both a need and a right to know the hazards and identities of the chemicals they are exposed to when working.
Taking Toxics Out of the Air
This 34-page PDF white paper discusses the technology and performance-based standards implemented by the EPA during the last 10 years and how they will assist in removing harmful toxins from the air.
Continuous PHA Revalidation
A process hazard analysis must be revalidated every five years. This paper discusses the merits of a new approach aimed at increasing the effectiveness of PHAs, called Continuous PHA revalidation.
Facility Major Risk Survey
This 8-page primer describes a method for identification of major acute risks in existing process facilities that can potentially affect on-site and off-site populations and for prioritization of mitigation methods.
