- Hydrocyclones For Calcium Sulfate Separation
Hydrocyclones are widely used in petrochemical industry to separate particles from fracturing flow-back fluids, mineral processing and other fields, because of the advantages of easy operation, simple design and low maintenance cost [1, 2].Separation efficiency, cut size and pressure drop are significant indicators for measuring the …

Mini-hydrocyclones, as a type of centrifugal separator, have smaller cut sizes and higher separation performance. With the rapid progress of industrialization, mini-hydrocyclones suitable for separating immiscible multiphase media have been widely used in key industries such as petroleum, chemical, mining and environmental protection.

ABSTRACT This study demonstrates the use of hydrocyclone as a thickener to precipitate sulfate ions from wastewater. Simulated wastewater containing different concentrations of sodium sulfate (100–400 mg L−1) dissolved in distilled water was prepared. Lime was added as the precipitating agent. Different flow rates of the feed (3–11 L min−1) were …

The use of networks of hydrocyclones as an alternative (or complementary) method to treat ultra-fine particulate slurries was considered. The previous works demonstrate the feasibility of utilising deliberate or adventitious aggregation prior to classification to improve the separation in hydrocyclones.

This work report a facile approach to efficiently separate surfactant-stabilized water (droplet diameter of around 2.0 μm) from water-in-oil emulsion via converting liquid water into solid crystal water followed by removal with centrifugation. The liquid–solid conversion is achieved through the solid-to-solid phase transition of calcium sulfate …

In hydrocyclones, the liquid is the fluid medium. There are two design classifications for cyclones. Uniflow or swirl tube cyclones are designed so that the clean gas or liquid leaves the cyclone in the same direction that the inlet gas flows. ... Small relative to other separation equipment. Can operate at a wide range of temperatures and ...

The separation efficiency is a crucial parameter to appraise the separation performance of hydrocyclones, which is referred to the particle recovery in the underflow. And, the particle recovery in the underflow is defined as the quantity ratio of particles discharged with underflow to those feed into the hydrocyclone for the same particle size.
