The use of spray nozzles to rapidly cool or quench gas streams is an essential application in many industrial processes, such as chemical reaction vessels, incineration, and power plant absorber gas inlet. An optimized spray quench design requires engineering analysis of the operating environment, spray nozzle performance and process reliability. This technical paper describes the design considerations for spray gas quench systems such as nozzle selection, process control, system configuration and reliability. Application of this knowledge can result in a gas quench system that operates efficiently and reliably with reduced vessel size, reduced atomization energy consumption, and minimized downtime, to achieve capital and operational cost savings for your process.09/16/2009

Positioned at the core of most supply chains, chemical firms must deal with many challenges to growing profitably -- flat demand, deflationary prices, and emerging competitors to name a few. Both chemicals firms large and small must develop the insight to change and win in today's ever-morphing competitive landscape. This white paper identifies and discusses how chemicals companies can combine data from many sources -- multiple ERP systems, multiple divisions and multiple applications -- maintenance, human capital, CRM, and supply chain to name just a few -- to create a complete or holistic view for critical decisions.

Operating and maintaining a reliable steam system is vital to chemical processing plants and can have significant cost impact on a plant's annual budget. Typical profit drainers in operating and maintaining a steam system include excessive fuel cost, inefficient steam generation, less-than-optimal steam utlization and poor condensate recovery. Ensuring adequate supply of steam often results in excessive capacity usage, expensive fuel choices or condensate draining to grade, leading to compromised efficiency levels and higher steam cost. Because steam systems dependency is unavoidalbe, addressing those three issues is crucial to minimizing steam costs.
This Chemical Processing Steam eHandbook presents an overview, steam technologies and strategies for reducing cost associated with using and generating steam including:
- Controlling steam system energy costs
- Real-time monitoring - how wireless devices help cut energy losses by detecting failed steam traps
- Additional resources

According to a U.S. Department of Energy survey, steam accounts for one-third of all the energy used in process plants. Monitoring and optimizing the cost of your steam system can yield big rewards. Ignoring inefficient operation easily could drain profits.
Operating and maintaining a reliable steam system is vital to chemical processing plants and can have significant cost impact on a plant's annual budget. Typical profit drainers in operating and maintaining a steam system include excessive fuel cost, inefficient steam generation, less-than-optimal steam utlilization and poor condensate recovery. This Chemical Processing Steam eHandbook presents strategies for reducing cost associated with using and generating steam, a 4 step approach for improving efficiency and insight on heat exchanger selection criteria. Specifically:
- Control Steam System Energy Costs - Steam system losses can silently drain profits
- Optimize Your Steam System - A simple four-step approach can improve steam efficiency
- Head Off Exchanger Errors - Selecting the most-appropriate heads for a shell-and-tube unit is crucial

Today's control system make it easy to add alarms. The result has been a proliferation of alarms that can overwhelm an operator and actually obscure situations that really require immediate attention. This paper provides practical guidance on effective procedures that can significantly reduce nuisance alarms and improve operator effectiveness.10/11/2004
This paper reviews the basic techniques for dynamic modeling of these two key operations. It covers considerations related to heat transfer, reaction chemistry, mass balances and the control system. It also discusses equipment configurations, performance characteristics and operational constraints.09/08/2004
Sure, the process engineer is proud of his HMI (human machine interface) and the operations manager is pleased with his KPI (key performance indicators) dashboard and how effectively the system is running with the implementation of his new MES/MIS solution. The historian and analytic solution get all the credit when a field equipment crisis is averted. Does anyone ever think to thank the lowly driver? Without data, the HMI is just a pretty picture, and the best analytics in the world are only ideas without any basis in fact. Plus, tens or hundreds of thousand dollars are spent on that, while the driver budget isn't even a line item on the spec sheet. The communication arteries and veins reach out to all areas of the field equipment, sending and receiving data, efficiently and tirelessly ensuring the ability to acquire, analyze and adapt to the situations at hand.02/10/2009
Automation systems today have become warehouses of knowledge and information. Beyond system configuration, years of effort is inevitably invested in them.

As the Department of Homeland Security (DHS) moves forward with the Chemical Facility Anti-Terrorism Standards (CFATS), the program continues to evolve. This white paper describes the ongoing CFATS compliance process (which is a combination of technical, procedural, and personnel security) and also provides insight regarding how to develop or revise a comprehensive Site Security Plan (SSP) and prepare for a CFATS Authorization Inspection (AI). Recommendations are relevant to SSPs for all tier levels and should be considered for a facility's initial SSP submission and/or any required SSP resubmission.

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.09/12/2014

Capacitance-type magnetic flowmeters have traditionally offered the advantage of having non-wetted electrodes and the ability to measure low conductivity fluids. However, they suffered from a sensitivity to flow noise and zero instability. Innovative technology overcomes these limitations and drives magnetic flowmeters into new areas of application, while reducing installed costs.07/18/2005

The past two years have been a real wakeup call for the industrial automation industry. For the first time ever it has been the target of sophisticated cyber attacks like Stuxnet, Night Dragon and Duqu.
In addition, an unprecedented number of security vulnerabilities have been exposed in industrial control products and regulatory agencies are demanding compliance to complex and confusing regulations. Cyber security has quickly become a serious issue for professionals in the process and critical infrastructure industries.
If you are a process control engineer, an IT professional in a company with an automation division, or a business manager responsible for safety or security, you may be wondering how your organization can get moving on more robust cyber security practices.
In order to provide you with guidance in this area, Tofino Security and exida Consulting LLC have condensed material from numerous industry standards and best practice documents. They also combined experience in assessing the security of dozens of industrial control systems.
