The online bentonite bleaching was only tested on the biomass of the unialgal S. obtusiusculus culture. The tests were focused on this strain, because it showed the most promising process parameters in terms of cultivation stability and biomass yields and therefore became the leading strain in the Advanced Biomass Value (ABV) project.

To separate topped crude into components, it must be distilled in a vacuum column at a very low pressure and in a steam atmosphere. In the vacuum distillation unit, topped crude is heated with a process heater to temperatures ranging from 370 to 425°C (700 to 800°F). The heated topped crude is flashed into a multitray

Our calcium- and magnesium-based products and minerals are used throughout the iron- and steel-making process as binders or flux agents to form slag. Slag removes harmful impurities, such as silica, phosphorus and sulfur. Lhoist products also help improve productivity and enable you to comply more readily with environmental legislation.

Moreover, it further promoted the sun-drying of bentonite to reduce energy and logistics costs while keeping higher proportions of the active product than in any other heating process. In Latin America, this methodology was applied for more than 80% of the clay used.

The uses of Bentonite Slurry in Pile Foundation and diaphragm walling wherein the bentonite is defined as excavation supporting slurry, lining tube or drilling mud are very similar and are considered one and the same.

Bentonite - A flow diagram for bentonite processing is provided in Figure 11.25-5. Mined bentonite first is transported to the processing plant and stockpiled. If the raw clay has a relatively high moisture content (30 to 35 percent), the stockpiled material may be plowed to facilitate air drying to a moisture content of 16 to 18 percent.

Clays are widely used as catalysts and catalyst supports for a quite broad range of processes. Clay catalysts have attracted much interest in catalytic application in petroleum refining industry. This review will focus on the using of clays and their modifications as catalysts and catalyst supports in the petroleum refining industry.

According to the physical characteristics of bentonite, after the sodium treatment, the bentonite powder is dried through the dryer, then after the dry powder go into the trapezoidal grinding mill. The main features of this equipment is stabile performance, high capacity and simple operation, which is a widely-used bentonite processing equipment.

The Frasch process produces sulfur of a very high purity of 99%. On the way from gaseous, liquid or solid feedstocks to petrol, heating oil or petrochemical products, the feedstocks need to be purified of sulfuric compounds. Crude oil and coal contain a variety of complex sulphur-containing organic species.

This study aims to analyze the results of the purification process of crude fish oil by-product of canning industry of lemuru fish by using bentonite adsorbent with different concentrations.

Bentonite is exported both in unprocessed (crude) and processed (including activated) forms. Though, export of crude bentonite account for a higher quantity, the exports of processed bentonite fetch higher value than the crude bentonite. There is scope to establish bentonite processing granulation and paint-grade processed bentonite units in the

Bentonite clay possesses excellent bleaching, binding, and healing properties. Bentonite contains more than 85% clay mineral called montmorillonite. Though there are many variations, calcium and sodium bentonite are the two major types. While sodium bentonite is the highly swelling type, calcium bentonite is the non-swelling type.

Bentonite is also eco-friendly, beneficial, and practical in the winemaking process to extract the excessive amount of protein from white wines. Owing to its high adsorption affinity, it is also exploited as a siccative to keep nutraceutical, pharmaceutical, and diagnostic products from extending expiry date and protect from moisture [164] .

The use of calcium sulphate dihydrate (CaSO 4.2H 2 O) as a bleaching agent during the refining of crude soya bean vegetable oil was investigated. Different weight ratios of CaSO 4.2H 2 O bleaching agent relative to crude oil (2, 4, 5, 10, 20 and 30 wt. %) were prepared. One sample of raw crude without any bleaching agent added was isolated as a control.

The mechanism of decolorization of crude maize and sunflower oils was studied by means of adsorption of β-carotene by a low-grade bentonite, containing mixed-layered illite-smectite. Decolorization depends on temperature and the time required for equilibrium decreases with increasing temperature. The study of the kinetics of adsorption showed that decolorization …
