 An introduction to LLE and agitated LLE columns

A Basic Primer on Liquid-Liquid Extraction

Processing, October 2020

Designing separations processes to accomplish the above is a challenge, especially as streams get more complex in composition. Though often overlooked, liquid-liquid extraction (LLE) is a powerful separation technique for both organic and aqueous liquids. Read More…

 Modularization finds new roles

Modularization Finds New Roles

CHEMICAL Processing, August 1st 2019

While providers of modular process systems and facilities will tell you modular builds were once a hard sell, modularization is now sought after for both traditional process systems, as well as new and novel applications. What is the reason? Read More…

 Distill Your Distillation Operations

Distill Your Distillation Operations

CHEMICAL Processing, July 1st 2019

Separations operations account for roughly 50–70% of the energy used in large-scale chemicals manufacturing. Distillation dominates for such separations. It behooves you to be on top of your distillation columns. Read More…

Liquid-Liquid Extraction: Generating Equilibrium Data


Equilibrium data and related information gathered from a liquid-liquid extraction laboratory “shake test” can provide information for process feasibility and column-type selection in the scaleup of liquid-liquid extraction processes Read More…

CO2 Capture Technologies Aim to Cut Costs

CO2 Capture Technologies Aim to Cut Costs


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

A Modular C2 Splitter


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

Is Modular Right for Your Project?


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

Moving To Modular


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. Read More…

Enriching Liquid-Liquid Extraction

Enriching Liquid-Liquid Extraction


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

Recovering and Recycling Low-Boiling Alcohols and Ketones


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

Generating Your Own VLE Data


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 

A Fresh Look At Liquid-Liquid Extraction 


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…
