High-pressure tests. In phosphate buffer (pH 6·7): Aliquots of 3·3 ml of sample containing 0·3 ml of cell suspension and 3·0 ml of phosphate-buffered solution (pH 6·7) were transferred in polyethylene pouches (20 mm width × 80 mm length) and heat sealed. Every pouch was placed in a second slightly bigger one to prevent accidental leakage ...
Phosphate hideout is a phenomenon which may occur under certain conditions in high pressure boilers where initially phosphate "disappears" and later it again "appears" in the water.
High-Pressure Steam Cycle and Boiler Water Treatment. High Pressure Boilers – As trisodium phosphate hydrolyzes in the water it produces a hydroxyl ion (OH) boiler water treatment. Dosing Agents for Steam Boiler Operation (Trisodium Phosphate) Dosing: Depending upon the boiler pressure and operation mode, Sufficient disodium phosphate must be ...

Silicon phosphate transforms into a new phase at high pressure and temperature. The high pressure phase is 14.8% denser than the low-pressure phase. The structure is based on a linkage of SiO 6 polyhedra and P 2 O 7 dimers. The way the two units are packed is reminiscent of the CsCl arrangement. The new structure is monoclinic and is a unique ...
High pressure boiler users such as pulp producing sites always faced many challenges on getting the boiler water chemistry under control. Congruent phosphate control …
The findings are interpreted in terms of a lipid phase transition induced by the high pressure, which is propagated to the associated phosphate transport system by a physical mechanism.

High-pressure evaporator chemistry is based on EPRI's phosphate guidelines, with tri-sodium phosphate as the only phosphate species. The …
High concentrations of sodium phosphate and sodium hydroxide were used for conditioning drum boilers in the 1950`s. However, corrosion occurred in the new high pressure plant, due to hydrogen damage and caustic gouging. This led to sodium hydroxide being abandoned in the USA in favour of phosphate treatment (PT).

Oxygen scavengers also used to allow magnetite (Fe 3 O 4) layer to form in the boiler. Boiler operating above 42 bar require a dearator. HP to UHP blrs (42 to ...
The Effect of Composition on the High Pressure Behavior of Rare-Earth Phosphate Minerals Karina M. Heffernan Abstract A comprehensive study on the effect of composition on the structural and elastic properties of MPO 4 (M = Ce 3+, Gd3+, Tb3+, Y3+, Sc3+) compounds has been completed. CePO 4 and GdPO 4 are isostructural with monazite (P2
The coordinated phosphate treatment uses the feed of sodium phosphates in maintaining the boiler water pH. One of the disadvantages of this treatment is that, on high-pressure drum type units, the detectable concentration of phosphate in the bulk boiler water can …
The resistance of the three strains to high pressure (375 MPa) was also assessed in a series of model food systems containing one of each of the three main food constituents: protein (1, 2, 5 and 8% w/v bovine serum albumin in PBS), carbohydrate (1, 2, 5 and 10% w/v glucose in PBS) and lipid (olive oil (30% v/v) in PBS emulsion).

A high-pressure sodium-vapor lamp. A sodium-vapor lamp is a gas-discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm . Two varieties of such lamps exist: low-pressure and high-pressure. Low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light ...
The relations between high temperature and high pressure processing-induced changes in the colloidal and soluble Ca phosphate equilibrium were evaluated in raw, pasteurized, and high temperature treated skim milk, ultrafiltration retentate and permeate of pasteurized skim milk, clear ultracentrifugation infranatant of pasteurized skim milk, and ...
Therefore, this study was conducted to evaluate the potential of combinational use of sea tangle powder and high pressure as an alternative to phosphate in emulsion-type sausage. Results revealed that this method was effective to replace the addition of phosphate and can be applied directly for industry. Volume 42, Issue 9.
This study investigated effects of high pressure (HP) treatment of pork meat at 150 or 300 MPa for 5 min before manufacturing sausages on the reduction of phosphate levels and compared to sausages manufactured with untreated pork meat (control sausages).Improvement in perceived saltiness, juiciness and overall flavour was observed in sausages manufactured using HP-treated …
In the high temperature method, ingredients are heated together at atmospheric pressure. Products are anhydrous, and production or borophosphates is likely. The boron flux method involves dissolving ingredients such as an ammonium phosphate and metal carbonate in an excess of molten boric acid. Use Borate phosphates are of research interest for ...
The concentration of phosphate in boilers water is dependent on drum pressure and water quality, a typical high pressure boiler fed with de-mineralized water would tend to run with low concentration of 1 to 5 mg/l range, while a lower pressure boiler running with softened water might go to 25 mg/l.

Most people with hyperphosphatemia do not have symptoms. However, in people with severe kidney dysfunction, calcium combines with phosphate, which lowers calcium levels in the blood (a disorder called hypocalcemia) Hypocalcemia (Low Level of Calcium in the Blood) In hypocalcemia, the calcium level in blood is too low. A low calcium level may result from a problem with the parathyroid glands ...
