Fuel for Thought: How to Keep Ethanol Production Green

July 5, 2007 11:27 am | Articles | Comments

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.

12 Key Rules When Dealing With Gas Control Systems

July 5, 2007 11:14 am | Articles | Comments

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.

How to Determine Calibration Frequency for Pipettes in the Lab

July 5, 2007 10:41 am | Articles | Comments

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.


Permeation Tubes

July 5, 2007 7:50 am | Product Releases | Comments

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.

Paddle Dryer

July 5, 2007 7:50 am | Product Releases | Comments

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.

Sanitary Rotary Batch Mixer

July 5, 2007 7:50 am | Product Releases | Comments

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.

Capacitance Level Probes

July 5, 2007 7:50 am | Product Releases | Comments

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.

Wear Sleeves for Machine Shafts

July 5, 2007 7:50 am | Product Releases | Comments

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.


Non-Corroding PVDF Exhaust Piping System

July 5, 2007 7:50 am | Product Releases | Comments

The SYGEF PVDF exhaust piping system has been designed to provide a non-corroding, safe system for the conveyance of aggressive exhaust gases and fumes. It conforms to FM 4910 (Cleanroom Materials Flammability Test Protocol) standards and has been tested per standard ULC S102.2 with a documented flame spread value of 0 and smoke spread value of 50.

Strainer for Piping System Components

July 5, 2007 7:50 am | Product Releases | Comments

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.

Centralized Mist Collector System

July 5, 2007 7:50 am | Product Releases | Comments

A "boxed solution" to airborne mist removal reduces pressure drop and energy use, delivers 10-year filter life, and promises 99.5 percent and greater capture efficiency. This long-life centralized CECO Mist Collector (CMC) system cuts operating costs and maintenance for mist elimination and allows effluent from multiple operations, even plant-wide, to be treated at one location. In turn, captured liquids and particulates can be collected for disposal or reprocessing.

HEPA and ULPA Filters With Special Gasketing

July 5, 2007 7:50 am | Product Releases | Comments

Absolute HEPA and ULPA filters have poured-in-place gaskets to ensure leak-free performance. The sealing method is uniform in depth and encompasses the entire filter sealing surface, eliminating gasket junctures, blemishes, and other corner leaks that occur with conventional high-efficiency filters.

Conical Dryer/Mixers for Chemicals

July 5, 2007 7:50 am | Product Releases | Comments

These conical dryer/mixers have been designed for various processing tasks required in chemical manufacturing and have been engineered for precision. Typical duties are drying under vacuum, mixing-blending, solvent recovery, and liquid or gas injection.

Rugged Misting Nozzles

July 5, 2007 7:50 am | Product Releases | Comments

MicroWhirl misting nozzles eliminate the dripping problems and fragility of impingement nozzles and offer improved durability in a wide range of applications including turbine cooling, odor and dust control, humidification, scrubbing, and coating.

Secondary Containment Basins

July 5, 2007 7:50 am | Product Releases | Comments

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.
