During industrial manufacturing, many companies use a wide variety of chemicals from methanol, acetone and benzene to foodstuffs like wine and edible oils stored in large tanks at different points in the manufacturing process. In a technique called “chemical tank blanketing,” or “padding” nitrogen is commonly applied to protect chemicals stored in tanks against contamination, degradation or chemical change as well as to prevent fire or explosions. This white paper first discusses blanketing basics and benefits. It reviews considerations for tank blanketing systems and discusses a newer approach, which is typically more cost effective for most applications, is that of generating nitrogen on-demand in the plant itself.
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.
Many industrial plants use dissolved air flotation to remove fats, oils and grease, and suspended solids from wastewater. Chemical additions are often kept higher than necessary to account for variations in influent water quality that are characteristic of industrial facilities. Continuous monitor
An easy to use generalized vent sizing formula is illustrated to be consistent with large scale industry experience and dedicated phenolic runaway reaction tests performed by Fauske & Associates, LLC. The formula also clearly explains the 1999 catastrophic failure of a phenol-formaldehyde reactor resulting from a grossly undersized relief system.
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.
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.
Over the past decade, cartridge-style dust collectors have overtaken baghouses as the preferred technology for dust collection in the chemical processing industry. Combining high efficiency filtration with compact size and reduced pressure drop, a high efficiency cartridge dust collector will in most cases be the system of choice.
Choosing the best cartridge collection system for a given application, however, involves research and attention to detail. This article will review four key areas of investigation. By reviewing these topics with a knowledgeable equipment supplier and knowing the right questions to ask, chemical manufacturing professionals will be better equipped to make informed dust collection decisions.

Whether we are headed toward an economic rebound or continuing with the current economic downturn, specialty chemicals manufacturers should take steps now in order to get or keep a competitive edge. But what steps should specialty chemicals manufacturers take? This Special Report will discuss actionable strategies including: Reducing costs while maintaining quality and compliance; Committing not just to "lean manufacturing" but to "lean supply chain" strategies; Implementing "agile manufacturing" practices.
While the activity of alarm rationalization is straightforward, its application can range from simple to extremely complex depending on resources and objectives. This white paper introduces two basic methodologies: Bounded or Unbounded, and evaluates the benefits of each.
Support for off spec materials, formula management, changeovers, parallel operations, lot trace and trace, unlimited unit of measure conversions, is key.
There are a host of enterprise resource planning (ERP) and supply chain management applications available to chemical manufacturersthe challenge is selecting the right one that offers a baseline product with industry-specific functionality. Many ERP applications available today are not industry-specific enough for chemical manufacturers and require major modifications, or, one must select from an industry template that may or may not fit specific needs.
There is also the chance that the software provider may not exist in two to three years (e.g., it may be acquired and the products future may become unknown), or the provider may not be financially secure, adding long-term risk.
Case Study of a Plant to Enterprise Solution
This white paper describes a case study of a real-life case harmonizing thirteen chemicals plants on one MES platform and bringing the plant floor at enterprise
level the Plant to Enterprise initiative (P2E) . The chemical plants are located on seven different production sites in four European countries: The Netherlands,
Germany, Denmark and Sweden.
NELES rotary control valves with Q-Trim have greater capacity than comparable globe-style linear valves with noise reduction trims widening rangeability, reducing weight and valve dimensions, and a 50% cost reduction compared to linear valves of comparable Cv. NELES rotary control valves from Metso Automation. Intelligent Reliability leads to Intelligent Results.
Many automation engineers are coming face to face with real fieldbus applications for the first time. Fieldbus offers many benefits, but installation requires some additional considerations over and above normal 4-20mA projects. This whitepaper discusses some of those issues, and shows you how to deal with them.
Liquid entrainment in a gas stream can be a disturbance in many industrial processes. In natural-gas processing, higher-order hydrocarbons, water or impurities have to be separated from the main methane stream. Upstream of gas compressors, droplets that can damage the impellers, have to be removed. With the recently acquired Knitmesh technology and the strategic alliance with Shell Global Solutions, Sulzer Chemtech can supply a broad portfolio of advanced, tailor-made systems for gas/liquid separation to customers in all industries.
Plants have traditionally used trays in the distillation columns to produce fuels grade ethanol. Trays of various configurations have been adequate in this service and their technology is well founded. The ever-present desire to reduce the energy needed to produce a gallon of ethanol has opened the doors to structured packings being used in the rectification sections of ethanol distillation columns.
This article discusses the choice of thin-cake (2 25 mm) separation technologies and their benefits to optimizing the effectiveness of the production process. The paper continues with a
discussion of clean-in-place operations to meet current Good Manufacturing Practices (cGMP) guidelines including riboflavin test and validations.
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.
