Custom engineered wet-mix process systems that feature colloid mills and positive displacement feed pumps are packaged to achieve specific requirements for emulsifying, dispersion, and particle size reduction.
In a recent survey, we asked readers what they most want to find in the pages of CHEM.INFO magazine. Innovation was the top response. In fact, it was the most popular and passionate request. As a result, we have searched the marketplace for innovative ideas and have assembled this special report examining 10 cutting-edge technologies. We hope they help you bring innovation into your plant.
When Spectrum Chemicals & Laboratory Products, a division of Spectrum Chemical Mfg. Corp., decided to switch from amber glass bottles to plastic bottles, it needed a high-quality plastic that would be compatible with most of its products.
The synthesis of most elastomers is carried out either by solution or emulsion polymerization. After the polymerization step, the polymer is separated from the solvent or emulsifying agents. This separation requires several process steps including coagulation, stripping, various mechanical separation stages, and finally drying. Beyond that, the existing technologies are energy consuming, waste solvent must be incinerated, and the installation of main and ancillary equipment occupies large spaces. The disadvantages of the solution and emulsion polymerization processes can be solved with the direct devolatilization process of elastomers contained in polymer solutions or polymer emulsion.
CPVC is an attractive alternative for wastewater treatment facilities because of its corrosion resistance, mechanical strength, and life-cycle economics. Here’s a real-world look at its strengths and capabilities.
An ethanol developer's speed to market, permitting expenses, material logistics, energy source, and selected co-products all relate to the dryer type and air pollution control technology decisions.
It's essential to understand material compatibility issues and your options when selecting pressure and flow control devices for calibration and sampling of reactive gases in the chemical process and quality control laboratory.
Since pipettes are subject to silent and random failures, the most important aspect of pipette quality control is maintaining a calibration frequency that achieves sufficiently high reliability. Here are step-by-step guidelines for you to use.
Drying to moistures of 0.5 to 0.1 percent or lower requires uniform heating and residence time. The K-S paddle dryer has been designed to reach these objectives with a continuous process. The mixing action of the paddle dryer's dual intermeshing agitators with heated wedge-shaped paddles provides for uniform heat transfer to the product and high heat transfer rates.
The Model 700-TH-40-SS sanitary rotary batch mixer gently blends batches of ingredients in parts as small as one per million with high uniformity, evacuates 100 percent of the batch, and can be sanitized rapidly with no tools.
Procap Series capacitance probes boast calibration stability, static discharge survival, and RF immunity. They use a simple timing technique that compares the discharge time of the probe capacitance to that of a reference capacitance.
Trace Source 57FPK gas-fed permeation tubes are designed to produce stable ppb calibration standards of arsine and other hydride impurities in polymerization grade ethylene and propylene. The tubes are used with a gas standards generating instrument that maintains the tube at constant temperature and flushes the tube with a constant flow of clean olefin matrix gas.
Speedi-Sleeves offer a sealing solution when machine shaft surfaces have been damaged or worn in operation. Made from stainless steel for corrosion resistance, these wear sleeves eliminate the typical need to replace or rework shafts whose surfaces have been compromised by abrasion due to environmental contaminants, high pressures, speeds, or inadequate lubrication.
The Model 50 duplex basket strainer has been engineered to protect piping system components, such as meters, pumps, and instrumentation, from damage and to help prevent expensive unscheduled downtime. It runs continuously to remove possible damage-causing particulate matter from the system flow, taking away unwanted matter through the use of two strainer baskets operating independently within a single housing.
These rectangular secondary containment basins, available in capacities from 40 to 3,500 gallons, meet or exceed EPA requirements for containment of hazardous chemicals. They are molded of high-density crosslink or FDA-compliant linear polyethylene, and their tapered design permits nesting during shipping.
