Benefits of State Based Control

State Based Control is a plant automation control design based on the principle that all process facilities operate in recognized, definable Process States that represent a variety of normal and abnormal conditions of the process. State Based Control, implemented with the latest developments in object-based technologies, delivers direct benefits to its adopters in a variety of Operational Excellence categories. It results in productivity increases, higher asset utilization of both people and process, automated responses and recovery for abnormal conditions and provides an environment for knowledge capture directly into the control design.

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.

Dust Explosion Protection using Flameless Venting

This 18-page white paper explores a new option – flameless venting – which has recently been developed for dust explosions and is being actively marketed as an alternative to vent ducting.

Peristaltic Pumps: A Simple Solution for Abrasive and Corrosive Chemicals

Finding the right pump for metering abrasive and aggressive chemicals can be challenging. The pump of choice needs to withstand harsh chemicals, accurately meter, and be simple to maintain and operate. More and more process engineers are turning to peristaltic pumps to solve their pumping problems, reducing life cycle costs and driving gains in process efficiency.

Special Report -- Control With Flow

With changes in temperature, pressure, density and viscosity all affecting volumetric flowmeter measurement, how can continuous processors accurately measure the flow of fluids? Download this Special Report to find out how Coriolis flowmeters provide a direct mass measurement that is unaffected by changing process fluid characteristics – improving both accuracy and optimizing operations at your plant.

Chemical Processing Special Report: Conveyors

No matter what industry you’re in, chances are you use some form of conveying. Whether it be pneumatic, flexible screw, aeromechanical or other, different conveyors are required to handle different products. But which conveyor is best suited for your operation? Despite the fact that conveyors have been around for almost a hundred years, this question still baffles many industries. In order to choose the right conveyor for your operations, you need to consider your conveyor's use - production, processing, packaging, and you need to consider your business objectives - improve operations? reduce labor?

In this special report, we look at the different types of conveyors, discuss the use of tubular bag conveyors, and provide 10 tips to prevent a variety of common problems that could occur with pneumatic conveyors.

Dust Explosion Protection using Flameless Venting

This 18-page white paper explores a new option – flameless venting – which has recently been developed for dust explosions and is being actively marketed as an alternative to vent ducting.

Properly Model and Control Batch Reactors

This paper covers key aspects for modeling and design of batch reactors, including: heat-up and cool-down performance, sensitivity analysis for reactor parameters, boil-up rate predictions, thermal stability under exothermic conditions, control system design and loop tuning parameters, condenser rating, and process emissions predictions.

Maximize Returns from Precious-Metal-Bearing Catalysts

Many catalytic reactions rely on platinum, palladium and other precious metal catalysts. When the activity of the catalyst declines to the point that it must be replaced, the used catalyst can be sent to a refiner to recover precious metal. This 8-page paper discusses the variouis factors that should be considered when using a refiner.

IT Security for Process Control Using Siemens SIMATIC PCS 7

Ensuring the security of industrial control systems is hardly a new topic. The earliest users of modern control systems in power stations and chemical plants saw the need to protect access to vital control functions from unauthorized use. Similarly, in industries such as fine chemical or pharmaceutical where “the process is the product”, manufacturers have always sought to protect the secrets of their unique processes from the prying eyes of industrial spies. This white paper by ARC describes how the Siemens AG PCS7 Security Concept bundles key security measures in seveal specific areas to create a deep hierarchy of security known as “defense in depth”.

A Review of Filter Press Basics and Issues

Filtration experts, over the years, have discussed filter presses and have indicated that soon they would be a thing of the past; the last filter press would be replaced by more modern equipment. This article discusses the perceived shortcomings of the filter press as well as the batch or continuous filtration alternatives to replace them.

Removing Liquid From Gas

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.

Special Report: Energy Efficiency

Reducing energy consumption and your plant’s environmental impact is a hot topic. In this Special Report we take a look at the organizational obstacles to avoid, how to enroll your employees in the quest, and the steps you need to take in order to manage your energy costs. We also delve in to practical energy efficient applications such as recovering exhaust heat in air conditioned facilities and the use of carbon synchronous belts.

Microturbine Testing

Microturbines are increasingly being used at various consumer sites to generate 480 VAC, three-phase electrical power, typically in the range of 25 to 500 kW. They are relatively small, combustion-gas turbines that run on natural gas, hydrogen, propane, diesel fuel, landfill gas (methane), and even some bio-diesel fuels. The turbines come in two varieties, simple-cycle and recuperated-cycle. Simple-cycle turbines are about 15% efficient, compared to turbines with reliable recuperators (that is, no moving parts) that double efficiencies to nearly 33%. They reintroduce exhaust heat energy into the cycle instead of wasting it. Better yet, system efficiency can reach 85% with an integrated combined heating and power (ICHP) installation.
