Analytical characterization of Crude Oil Separation - Part 2: EOR | Droplet Size Distribution

The second LUM live webinar in the series “Analytical characterization of Crude Oil Separation” focuses on the use of the LUM measuring devices LUMiReader PSA and LUMiSizer in the area of enhanced oil recovery (EOR) and for determining the droplet size distribution in crude oil emulsions.


“Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. According to the US Department of Energy, carbon dioxide and water are injected along with one of three EOR techniques: thermal injection, gas injection, and chemical injection. More advanced, speculative EOR techniques are sometimes called quaternary recovery. There are three primary techniques of EOR: gas injection, thermal injection, and chemical injection.” [cited from]


EOR case studies using the LUMiSizer analytical centrifuge and the LUMiReader PSA separation analyzer will be presented during the webinar. To determine the water droplet distribution in waxy crude oil emulsions, users apply the LUMiSizer dispersion analyzer.

Two examples from the literature are introduced in the webinar.


Analytical characterization of Crude Oil Separation I Part 1: DEMULSIFICATION

Watch this new LUM webinar to get answers on the three demulsification key questions: how to quantify quickly and easily the kinetics, the amount and the quality of separated water in crude oil-water emulsions.

Save energy, labour and decision time and run your demulsification tests either in real-time using the LUMiReader PSA or preferrably accelerated using LUMiSizer or LUMiFuge state-of-the-art analytical centrifuges.

This presentation reviews existing successful approaches and provides new data and insights into several aspects of crude oil demulsification. Demulsifier selection and dosage optimization, accelerated bottle test procedures with and without polymer form part of the presentation.

Fast and precise counting and sizing of every nano- and micro-particle in suspensions and emulsions

Prof. Dr. Dr. Lerche, managing director of LUM GmbH, explains how the new LUMiSpoc® quantifies the size distribution of dispersed mono- & very polydisperse particles and counts the concentration of the particle classes by the innovative single particle light scattering (SPLS) technology.

The highly advanced LUMiSpoc® measures simultaneously fore- & sideward light scattering, features an unparalleled resolution & dynamic range, minor dilution factors and a very short measurement time.

SEPAWA Webinar: Direct and accelerated stability testing extended by temperature ramp

After the SEPAWA Conference 2020 was reduced to a solely virtual event due to COVID-19, the live talk by Dr. Arnold Uhl "Direct and accelerated stability testing extended by temperature ramp" was switched to a webinar.
This is the recorded full version.

Dr. Uhl explains an innovative method for accelerated stability testing for personal care and cosmetics products according to ISO/TR13097 and ISO/TR18811.


From pigment to dispersion to coating - comprehensive characterization of TiO2

"From pigment to dispersion to coating - comprehensive characterization of TiO2"
continues the LUM LIVE webinar series and successfully helps our customers to develop, formulate and bring new and improved products to market.
Case studies discuss how to:
- count TiO2 particles.
- examine pulverized TiO2.
- determine particle size distributions of titaniumdioxide in suspensions.
- characterize the formulation stability of titania products in a direct way, accelerated and in real-time.
Benefit by using LUM instruments for your application in the field of batteries, ceramics, food, inks, paper, plastics, sunscreen formulations, wallpaints, etc.

Inform yourself how LUMiFrac® users determined the adhesivestrength of coatings with TiO2 particles on various substrates, such as cement.



Dispersion Stability , Redispersibility & Particle Characterization- Adjuvants | Vaccines | Influenza

"Dispersion Stability , Redispersibility & Particle Characterization- Adjuvants | Vaccines | Influenza" continues the LUM LIVE Webinar series to enable our customers successfully to develop and to
formulate new and improved products and introduce them into the market by using LUM Instruments.
The patented STEP-Technology is applied for the in-situ characterization of particle properties and
the direct characterization of the physical formulation stability of adjuvants and vaccines .
Real-time, real-condition stability studies and the accelerated stability studies are discussed on the
basis of the WHO Guidelines.
A redispersibility case study on aluminum-containing adjuvants is complemented with information on
particle and aggregate sizing, nano particle adsorption and applications related to influenza.
Learn how LUMiReader PSA and LUMiSizer let you follow our slogan The Next STEP in Dispersion
Analysis and Materials Testing.


An innovative concept for real-time and accelerated emulsion and suspension stability testing

In this recorded webinar from COSSMA 2016 you learn how to determine the dispersion stability of cosmetic formulations in real-time vs. accelerated via analytical centrifugation according to current DIN and ISO standards.

Dr. Arnold Uhl presents the technologie using the examples of an oil-water-emulsion and a nail varnish suspension.

STEP-Technology® for Particle Sizing


The composition of cosmetics, HPC, paint, latice and pigment products is often characterized by complex formulations, including many ingredients of manifold nature.

For example, a moisturizing lotion with Titanium dioxide (o/w) contains 14 ingredients.

The determination of particle size distributions of individual ingredients allows for the early detection of deviations in the raw material, prior to their subsequent use in formulation.

These are your benefits of a measurement with STEP-Technology®:

- Particle and droplet sizing over whole sample

- True raw data

- direct physical measurement

- From nm to µm same principle

- Multimodal systems with high resolution

- No restrictions regarding liquid continuous phase (closed cell)

Particle sizing of raw materials using a Dispersion Analyser LUMiSizer® (ISO 13318) is in addition to this instrument‘s use for accelerated stability testing (ISO/TR 13097) of formulated products.

A New Standard in Adhesion & Cohesion Testing

Pioneering technology measures adhesive bonds, tensile strengths, coatings & composites much faster than regular pull-off tests and requires no clamping.

A joint webinar by Prof. Dr. Dr. Dietmar Lerche, Managing Director of LUM GmbH and Uwe Beck from the Federal Institute for Materials Research and Testing (BAM).
