Use of amine solutions for the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas is the most common method, and, in this process, operational problems because of foaming are reported. Foaming can lead to the entrainment of liquid into downstream process equipment and might result in a situation in which the process specification...

At Kiviks Musteri AB, situated in the southeast part of Scania, a wide variety of products based on fruits and berries, are produced. One of these products is base apple wine, which is used for the production of cider and mulled wine and also is sold to other producers of cider. A foaming problem has occurred at some customers when the cider is bottled, and this problem has been traced to the b...

This study investigated the effects of freeze-milling on the structural and functional properties of rice proteins (RPs). Sodium dodecyl sulfate–polyacrylamide gel electrophoresis showed that freeze-milling slightly influenced the subunit bands of RPs. Secondary and tertiary structures were studied by analyses of Fourier transform infrared spectra, sulfhydryl and disulfide bond contents, and su...

Anaerobic digestion foaming has been encountered in several sewage treatment plants in the UK. Foaming has raised major concerns for the water companies due to significant impacts on process efficiency and operational costs. Several foaming causes have been identified over the past few years by researchers. However, the supporting experimental information is limited and in some cases absent. Th...

As a result of the ambiguity and complexity surrounding anaerobic digester foaming, efforts have been made by various researchers to understand the process of anaerobic digester foaming so as to proffer a solution that can be universally applied rather than site specific. All attempts ranging from experimental analysis to comparative review of other process has not fully explained the condition...

The nutrient composition and flour functionality of horse gram seeds were evaluated of their flour characteristics. The objective of the present study was to evaluate horse gram seed with the aim of quantifying physiochemical and functional properties information that might serve as a guide to exploit its potential and benefits for human and animal nutrition. The proximate compositions (%) were...

The effects of limited enzymatic hydrolysis with trypsin on the physicochemical and functional properties of buckwheat protein isolate (BPI) were investigated. The protein constituents, free sulfhydryl (SH) contents and surface hydrophobicity (Ho), as well as some selected functional properties, such as protein solubility (PS), emulsifying (including emulsifying activity index, EAI and emulsion...

This study investigates effects from different drying methods (vacuum oven dried vs. freeze dried) on the rheological, functional and structural properties of chicken skin gelatin compared to bovine gelatin. Vacuum oven dried chicken skin samples showed a higher gelatin yield (12.86%) than freeze-dried samples (9.25%). The latter showed a higher melting temperature (32.64oC) and superior foamin...

As egg is a primary source of high quality proteins and offers a balanced distribution of basic food constituents such as minerals (iron, calcium, phosphorus and potassium) and vitamins, particularly vitamin E, A, B12, B2 and folic acid alongside high amounts of lipids, such as triacylglycerols, phospholipids and cholesterol to the body. Eggs were spray dried, that ultimately increase the shelf...

In hydrocracking and other foaming reactors, the foam rises to the top because it has a higher gas fraction than the bubbly mixture from which it comes. The high gas hold-up in foams is undesirable in chemical reactors because it strongly decreases the liquid residence time and in hydrocracking reactors also promotes the formation of coke. To study foams we built a cold slit bubble reactor whic...
