Virtually every process-plant manager pursues the commendable goals of safely extending equipment life and maximizing both the availability and reliability of plant assets. Achieving these objectives usually requires upfront effort and money — both of which can be scarce resources. But even the realistic manager who knows that reliability comes at an ufront price may not want to authorize these...

Many readers of this magazine are familiar with the impact of a hurricane — both professionally and personally. Plants along the U.S. Gulf and the southern Atlantic Coasts, for instance, live with a high probability that one of these storms cross their paths, and therefore are generally prepared for such storms. Last month, however, the force of a hurricane hit a most unlikely place, the Northeast...

Wet fluegas desulfurization (FGD), also known as wet-scrubbing, is a popular pollution-abatement technique for removing acid gases, such as SO2 and HCl from fluegas produced during coal-fired power generation and industrial combustion processes. Wet scrubbing is used in association with power generation, thermal oxidizers, kilns, incinerators, boilers, foundries and other combustion units. Also...

How to utilize a pipeline inspection gauge (pig) in a crude-oil pipeline that requires a pressure control valve can be a bewildering question for process engineers, especially in cases where the oil pipeline does not have any pig-launcher and receiver facilities. The challenge becomes how to keep the pressure profile unchanged along the length of the pipeline. This task is complicated when the pipeline...

Equipment for generating synthesis gas (syngas; mostly CO and H2) is typically the most expensive part of an overall gasification complex. Understandably, the owners of gasification assets seek the highest value for the syngas produced by these assets. The methodology used in this study describes which gasification products may yield the highest value for the resulting syngas, given certain input data and...

When designing a batch system, engineers often select the control solution based on the size of the system. It is traditionally thought that small batch systems require a controller-based sequencing solution, while larger systems require a server-based solution. However, despite traditional practices, the size of the system is not always the best indicator of an appropriate solution. A small application or...

Compared to petroleum refining, the coal gasification process appears less complex. The chemistry behind the primary gasification reactions have been well known for around 100 years, and coal is more plentiful than petroleum in the U.S. and in some other areas. So why then, are petroleum refineries common and coal gasification plants so rare? There are a host of reasons for why petroleum has historically...

I drink tap water! There, I finally said it. I am out of the closet — the water closet. My two sons are now cowering with shame, wondering how they can possibly ever face their Dasani-drinking friends again. It was maybe 20 years ago when I first encountered the concept of bottled water. What a strange idea! Why would anybody want to pay for something that’s free — and everywhere —...

Preventing dust explosions is not rocket science, and still these disasters occur. This article is written to help prevent these accidents. It describes how and why these explosions happen and what can be done to avoid them.   Why they occur Dust explosions occur when three conditions are present simultaneously. The first is that there is a dust cloud of a combustible material (the fuel). The second...

One of the most significant limitations on the operation of dynamic compressors (axial and centrifugal compressors) is the low-flow limit known as “surge”. A sudden valve closing, such as for emergency shutdowns or for a suction/discharge valve, presents significant challenges to anti-surge valve sizing and selection. Anti-surge valve requirements depend to a large degree on the compressor...

Throughout the chemical process industries (CPI), various chemicals must be injected into process streams to serve a variety of purposes. Chemical-injection systems can be arbitrarily defined as those systems that are used to inject chemicals at a flowrate that is less than 1 to 5% of the main process stream. Table 1 shows a non-inclusive list of chemicals that are typically added into process streams via...

More opinions on ChE education I would like to contribute to the discussion on “practical” ChE education (CE, September 2012). After graduation, I as well didn’t know what a pipe flange was, nor a gasket, didn’t know how to read a pump curve, didn’t know how to size a relief valve and so on. I could have learned more that applies to the CPI [chemical process industries] in an...

Fans and blowers are common in air-handling and movement systems used in the chemical process industries (CPI). Two major uses of fans and blowers are in pneumatic conveying systems and in ventilation and air-pollution-control systems. Powering fans and blowers can contribute significantly to costs, and their efficient operation can be affected by the way plant operators select and run their systems...

According to my version of the story, Robert Kohler said, “We don’t need visas to enter Hungary.” According to Robert’s version, he said, “It’s easy to get visas to enter Hungary.” Either way, he was wrong. Either way, he got us to Budapest. Robert Kohler and I visited the OMV plant in Schwechat, Austria, on a Friday morning. At Robert’s urging, we decided to...
