CO2 Capture Technologies Aim to Cut Costs

CHEMICAL ENGINEERING, August 2017

Despite cost hurdles, CO2-capture technologies continue to advance, driven by the critical role of CO2 capture in achieving emissions-reduction goals

Among the possible strategies for addressing climate change risks are CO2-removal approaches, including the capture of CO2 from large emitters, such as power plants and industrial facilities, and also the capture of CO2 from ambient air. These technologies have been explored for some time, and commercialized in some cases, but have yet to be deployed widely, largely because of cost issues. Read More…

A Modular C2 Splitter

HYDROCARBON ENGINEERING, April 2017

A typical olefins plant produces several purge gas streams, which are usually flared or used as fuel. Some of those streams contain valuable components such as ethylene and propylene. Read More…

Is Modular Right for Your Project?

CHEMICAL ENGINEERING, January 2016

Modular construction provides many benefits, but the decision to go modular should be thoroughly investigated Modular construction, which includes projects from small- and large-scale process systems to pilot plants to entire modular facilities, is a growing trend in the chemical process industries (CPI). More than ever before, project owners are considering employing modular rather than traditional construction, because it often provides significant savings in schedule and labor costs.

However, even though there are valuable benefits, modular construction is not suitable in every situation. This article discusses the advantages of modular projects, as well as provides advice on how to determine if a modular approach is the right the solution for your project needs. Read More…

Moving To Modular

CHEMICAL ENGINEERING, January 2015

If the word “modular” brings to mind a trailer office parked on site, it’s time to revisit modular systems.Today’s modular system go well beyond office space and tool sheds, and can contain almost any- thing from a skid-mounted filtration system to a clean room laboratory to a petroleum refinery, which is built elsewhere and delivered as a complete unit to a site, where it is then erected.

Enriching Liquid-Liquid Extraction

CHEMICAL ENGINEERING, November 2004

M any of today’s liquid-liquid- extraction columns have longer plant tenures than the engineers who are responsible for pushing their buttons. Over time, process engineers come and go, while the original procedures and understanding of the column design become diluted. Read More…

Recovering and Recycling Low-Boiling Alcohols and Ketones

CHEMICAL ENGINEERING, February 2000

Manufacture the chemical process industries (CPI) are under increasing pressure to minimize the discharge of organic compounds. As a result, more companies are turning to onsite purification and recycling systems. However, recovering low-boiling organic compounds, such as ketones or alcohols, poses significant challenges, since these chemicals form single-phase azeotropes with water. Read More…

Generating Your Own VLE Data

CHEMICAL ENGINEERING, March 1995

When engineers need to separate one chemical from another, they first decide on the process concept: weather to employ distillation, extraction, crystallization, or some other unit operation. Read More…

A Fresh Look At Liquid-Liquid Extraction 

CHEMICAL ENGINEERING, February 1991

Distillation may be the process industries workhorse for separating the components of a liquid mixture. But there is a broad and growing range of situation outlined below in which liquid-liquid extraction (LLE) is the method of choice. Read More…
