Chloritrol valveless metering system

March 5, 2012

The Chloritrol valveless metering system provides accurate, maintenance-free injection of sodium hypochlorite into water. Since liquid sodium hypochlorite tends to out-gas, traditional metering tools present a challenge for maintaining accuracy. Chloritrol’s valveless duplex pump design has one high-pressure pump that injects the sodium hypochlorite directly into the water main, and another that removes out-gas bubbles from the inlet side of the other pump head.

FlexMixer

March 5, 2012

The FlexMixer — the first single-use mixing bag that can be used to mix materials of any viscosity or density difference — can be scaled to over 10,000 L and does not have any internal impeller or actuator. An integral perforated diaphragm in the mixing bag is moved up and down by a simple low-cost mechanism to provide reliable, efficient and complete mixing. Compared to traditional mixing systems, FlexMixer integrates materials more completely and efficiently and eliminates the need for cleaning and/or sterilization between batches, saving companies valuable time and money.

Model LB100 Ultrasonic WeatherStation

March 5, 2012

The Model LB100 Ultrasonic WeatherStation meets the growing need for real-time, site-specific weather information. An all-in-one weather sensor calculates apparent wind speed and direction, barometric pressure, air temperature, relative humidity, dewpoint and wind-chill temperature. An internal compass and global positioning system are optional features; when both are included, true wind speed and direction can be calculated, which enables more accurate estimates of fugitive emissions flowrates. This enables the facility to employ the most-effective control technology.

DTR Series transmitters

March 5, 2012

DTR Series transmitters provide a simple and practical solution for combustible- or toxic-gas monitoring in hazardous environments. These rugged instrments can be configured for one or two sensors, and allow complete calibration and configuration to be performed without compromising the explosion-proof integrity of the unit. In addition, the sensor can be calibrated by a single worker in a hazardous areas without declassification. The transmitters are available in a two-wire, intrinsically safe configurations, and with catalytic, electrochemical or infrared sensors.

Model 204 Oil in Water and VOC in Water analyzer

March 5, 2012

The Model 204 Oil in Water and VOC in Water analyzer detects oil and volatile organic compounds (VOCs) with a high degree of accuracy. Key to accuracy is a membrane technology called Sample Transfer Stripper (STS) that provides an ultraclean, dry sample. Model 204 is competitive in price with similar detectors and requires less maintenance.

O’Brien & Gere delivers full-project lifecycle services in line with its three business units — Environmental Solutions, Total Water Solutions and Capital & Facilities Programs. In addition, the firm provides incremental and/or full-service project delivery approaches to assist clients in reaching their project goals and objectives, while tailoring contracting arrangements to meet specific business needs and/or procurement strategies. Services offered include: conceptual design/study; fabrication; construction; system integration; commissioning; and operations and maintenance.

ChemCAD suite of simulation software

March 5, 2012

Version 6.0 is the latest release of the ChemCAD suite of simulation software. This version incorporates open architecture with improvements to both the graphical user interface and the core engineering functionality of the program. Using information based on recommendations from customer interviews, this state-of-the-art process simulation package seamlessly integrates into the wider chemical engineering computing environment.

Computational Fluid Dynamics Software

March 5, 2012

An updated methodology for determining pressure drop calculations in custom-engineered design projects enables modeling of flow through strainers and valves to accu-rately determine the pressure drop for any fluid traveling through stainless perforations or mesh, under virtually any design conditions. The new computational fluid dynamics (CFD) software allows comprehensive fluid-flow and heat-transfer simulations. Another recently developed tool expands the illustrative dimension of analysis to create 3D computerized product models.

Engineer’s Aide CHEMPRO 8

March 5, 2012

The new version of Engineer’s Aide CHEMPRO 8 features unique three-phase flash calculations. Developed as part of the American Petroleum Institute Technical Data Book project, it accurately handles aqueous-hydrocarbon systems. CHEMPRO 8 combines fluid flow simulation and process simulation capabilities. The software handles liquid, gas and multi-phase piping systems, and it creates simulations that can determine compressor performance.

E2.6HS1200 combination steam cleaner and high-pressure hot-water washer

March 5, 2012

Ideal for chemical and pharmaceutical operations, the E2.6HS1200 is a compact all-electric combination steam cleaner and high-pressure hot-water washer. It features two cleaners in one with hot water for blasting away dirt, grime, and dust, and a steam option for removing grease and oil and disinfecting surfaces. It reaches optimum cleaning capability by providing continuous hot water or steam quickly and continuously, even during long periods of operation.
