Increasingly precise process control strategies, often linked to computer control, have accelerated the use of sophisticated on-line chemical composition analyzers in plant applications. Instruments such as gas and liquid chromatographs, ion chromatographs, laser optic instruments, atomic absorption instruments and specific ion analyzers, which were rarities in laboratories ten years ago, are now found routinely in plant settings.
While continuing miniaturization and “rugged-ization” of the electronics are making the instrumentation circuitry more tolerant of the plant environment, the level of contamination in plant samples compared to laboratory samples continues to plague the process. This white paper reviews the factors in plant operation that may affect the deliverability of acceptable samples and provides guidelines for addressing these factors.
Increasingly stringent clean air standards and heightened concerns over greenhouse gas emissions are driving technology enhancements in the chemical processing industry. This white paper explains some of the abatement challenges this industry faces and demonstrates how many chemical processors are integrating newer, more efficient emission control technologies for the destruction of Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs).
The paper also includes a case study, demonstrating how one Pure Terephthalic Acid (PTA) plant saved nearly one million dollars by upgrading to a newer thermal oxidizer technology.
In recent years, TOC analysis has become accepted in the industry as the standard method and the only reliable online method used to determine contamination in waters, to control processes, to prevent product losses and to minimize waste. It is especially important to monitor this parameter in applications such as condensate return water, boiler/feed water, etc. In boiler/feed water and in industrial steam generating systems, carbonic acid corrosion of condensate lines is often a serious problem. Depending on the application type, analysis of only one parameter (e.g., TC) is generally not sufficient to make any useful process decisions. Multiple-parameter analysis (TOC, TC, TIC, VOC etc.), as carried out in the Hach BioTector B3500c analyzer, is proven to be more useful and always superior to single-parameter analysis in the industry.
Solid-liquid separation is an instrumental part of chemical processing. To separate the solid particles, filter media made of textile or metallic materials and of composite materials are used as the basis for the filter cake. Often there will also be a washing process to improve the purity of the filter cake or to increase the yield of the liquid phase. Solid-liquid separation can be carried out in continuous or batch operation. There are many factors for selecting the right process filtration system for your specific application. This white paper reviews methods for identifying the right process filtration technology for your application and highlights case studies illustrating the methods discussed.
Chemical facilities are under mounting pressure to process ever larger quantities of wastewater to increasingly higher standards while staying within a variety of cost constraints. Plant operators face the dilemma of how to maintain treatment throughput at reasonable cost even when the plant reaches design capacity. Potential changes to production mixes can compound the challenge. Fortunately, adopting the latest wastewater-treatment technology can inject new life into a plant, extending useful asset life without heavy upfront capital investment. In this Chemical Processing Wastewater eHandbook we take a look at how to boost wastewater improvement efforts including:

Chemical makers increasingly are focusing on water-related issues. In particular, concern over availability is spurring leading operating companies to implement a host of novel strategies and technologies to optimize water use. Chemical makers are implementing strategies and solutions to scale back on their overall usage of water, reuse water and put clean water back in to circulation.

Chemical Processing has taken an in-depth look at just industrial wastewater -- how it is used, processed and potential management and compiled a comprehensive Special Report titled: Make the Most of Water. This informative Special Report covers such topics as:
Is water the new carbon -- what path will regulating water take
How to optimize water use
Micropollutants -- defining, managing, and communicating potential risk
During many chemical operations, cake washing is required since no filter system can remove all of the mother liquor by pressure or vacuum dewatering only. The topic of how to most efficiently wash the cake is important. This article introduces pragmatism into cake washing theory and will help engineers during their decision-making processes.
All of the benefits of Product Lifecycle Management can be erased by significant non-compliance events that impact a company through fines, penalties, negative publicity, or prohibition to sell a new product in key markets. Without a sustainability strategy, the PLM value proposition is at risk.
When choosing filters for your cartridge dust collector, a Total Cost of Ownership (TCO) calculation allows you to make the most economical and sustainable choice. TCO is a step-by-step evaluation that explores energy use, maintenance and other factors to compare the real costs of operating a dust collector with different filters. This white paper explains how to perform TCO calculations to save money, time and energy.
Over the past 10 years, manufacturers have faced an increasing number of compliance and product quality challenges, ranging from new regulations to product recalls. This White Paper details the business case for an integrated and comprehensive view of product and REACH compliance processes. If "done right," it is expected that these improvements to the compliance process can not only provide time and cost savings but also open doors to new markets, lower risks associated with complex supply chains, protect the reputation of the brand, and create a foundation for environmental sustainability.
The ever present emphasis on technological efficiency is just one of several forces behind the pressure on companies to "go green" despite a trying economy. The ultimate criterion that determines whether a motor is truly green is energy efficiency. Technology, long the key to efficiency, can help resolve this issue.
Gaseous oxygen measurement with amperometric sensors is the most direct and easiest solution for oxidation and explosion protection.
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.
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.
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.
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.
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.
