Chemical Engineering’s Facts At Your Fingertips package includes a series of twelve condensed, one-page reference cards that provide useful rules of thumb, common equations and other practical tips for designing, operating and maintaining chemical process equipment.
This guidebook is available in a downloadable PDF.
The topics covered in 2016 include the following:
Process Hazards Analysis Methods
Different methodologies are available for conducting the structured reviews known as process hazards analyses (PHAs) for new processes. PHAs are often conducted or moderated by specialists, with participation by the design team, representatives of the facility owner, and experienced process operators. Each different PHA method is better-suited to a specific purpose and should be applied at different stages of the project development. The table includes brief descriptions of some of the most widely used PHA methods in the chemical process industries (CPI).
Weighing Equipment Selection
The number of options available for scales and weighing equipment can make it difficult to determine which instruments will offer the best value and which will meet the application requirements. Focusing on the following ten areas can help reduce the time needed to research available models and help ensure a good value.
Particle-Sizing Technology Selection
This column summarizes the strengths and limitations of some widely used industrial particle- analysis techniques.
Organic Chemical Functional Groups
Chemical functional groups are critical determinants of the properties and reactivity of compounds. The following provides a review of the structures of common organic functional groups, along with some notes and examples.
Insulating Heat-Transfer-Fluid Piping
Heat-transfer-fluid (HTF) system piping is insulated to reduce heat loss and prevent worker contact with hot surfaces. Insulated piping minimizes the effects of changes in ambient temperature to help ensure precise control of process temperature. Proper design of the HTF system and its insulation is required to reduce the risk of fire as a result of fluid leakage into insulation.
Key Reactions for the Petrochemical Industry
A handful of compounds derived from natural gas and crude petroleum are converted into a vast array of industrial petrochemicals. Starting materials for most petrochemical intermediates include synthesis gas, ethylene, propylene, butadiene and BTX (benzene, toluene, xylenes). This one-page reference provides an overview of the chemical routes and reactions required to manufacture these fundamental petrochemicals, as well as reactions for generating some of their immediate
Industrial Gas Burners
Combustion in industrial burners is a critical operation in the chemical process industries (CPI) for supplying thermal energy for heat transfer, fluid heating, steam generation, distillation, endothermic chemical reactions, metal melting and others. Burners are mechanical devices utilized for mixing proper quantities of fuel and air, and also for maintaining a stable flame inside fired equipment. Included here are brief descriptions of key aspects of industrial burner components and operation.
Distillation Column Design Factors
Distillation is a critical separation tool for many applications in the chemical process industries (CPI), and the intelligent design of a distillation column can have a large impact on eventual process performance and efficiency. This reference sheet outlines the design process for distillation columns and defines several key design factors in this area.
pH Measurement in Industrial Waters
Determination of pH is a critical and ubiquitous operation whenever water is used in the chemical process industries (CPI). This one-page reference provides a review of pH chemistry and information on pH measurement equipment in CPI applications.
Agglomeration is a natural phenomenon in which solid particles stick to each other or to surfaces. When unwanted, agglomeration can cause problems, such as caking, buildup or lumping, but it is also an important particle-size enlargement process widely used in the chemical process industries (CPI) to help overcome challenges, including segregation, difficult flow, low bulk density and others. Agglomeration can also help control particle-size distribution and reduce potentially hazardous aspects of the solids, such as dust. This one-page reference provides information on agitation, compression and sintering methods of agglomeration and their mechanisms. Agglomeration methods to enlarge particulate solids can be broadly broken down into three general categories: agglomeration by agitation (sometimes referred to as wet agglomeration or tumble/growth agglomeration; pressure (compaction) agglomeration, and agglomeration using heat (sintering).
Sampling for Internal Corrosion
Properly selected and executed sampling techniques are essential for assessing, controlling and mitigating internal corrosion of pipes and other assets in the chemical
process industries (CPI). Key data for evaluating an asset or piping system for internal corrosion include the following: materials of construction, properties of fluids carried, operating conditions and valid analytical data from proper sampling. This reference describes considerations for sampling of internal corrosion.
Solid-Liquid Separation: Classification, Design and Testing
Whether to remove solid contaminants from a liquid or separate a solid product from a solvent, solid-liquid (S-L) separation is a common unit operation across the chemical process industries (CPI). This one-page reference provides an overview of S-L methods, design and testing.
