This safety instrumented system has cybersecurity protection
The ProSafe-RS safety instrumented system (SIS; photo), a product in the OpreX family, recently obtained ISASecure CSA Level 1 certification from the ISA Security Compliance Institute (ISCI). This is the first time a safety instrumented system has obtained this cybersecurity…
Use this flowmeter to monitor seal leakage in gas compressors
The ST75 mass flowmeter (photo) provides precision measurement in small lines for the detection of hazardous, non-compliant and costly gas leaks, including the monitoring of seal leakage from gas compressors. It measures air or gases from 0.01 to 559 std.…
Measure density and concentration with this system
The InlineSENS (photo) density measuring system combines both a radiation source and scintillation detector in one device. Its use of low-energy gamma radiation provides strong responses to even the slightest change in product composition, with extremely low dose rates. The…
This new bag emptier has a body that tilts
The tiltable Dima bag emptier (photo) can improve product intake processes, since less time is needed to clean, inspect or replace parts. The tiltable body enables the Dima to be opened for easy access to areas that are normally difficult…
Project Development: The Importance of Cost Estimating
Following a standardized project-development process, in combination with a robust cost-estimate classification system, can help to ensure that projects meet their financial goals Cost estimating is critical to support decision-making during the project development process for projects in the chemical…
Can You Trust the Joukowsky Equation for Waterhammer?
The Joukowsky equation is often relied upon to determine the maximum possible fluid pressure inside a pipe, but there are certain scenarios where this equation does not return the expected conservative result for overpressurization We engineers love our formulas. Especially…
Explosion Protection: Considerations for Combustible Dusts
Managing the risk from combustible dust explosions involves a number of strategies for preventing explosions, as well as isolating, venting and suppressing explosions if they occur. Complying with applicable NFPA standards is a pathway toward minimizing risk Combustible dust explosions…
Technology Profile: Production of Caprolactam from Benzene
Caprolactam (Figure 1) is a cyclic amide widely used as a chemical intermediate. The main forms of caprolactam are molten (liquid) and flakes. At ambient temperatures, it is a white, hygroscopic, crystalline solid. Almost all caprolactam is used as monomer…
Facts At Your Fingertips: Adsorption bonding
Physical adsorption phenomena play a critical role in many separation and purification processes, including separations of industrial gases, purification of gases, moisture removal from fluids, water purification and others. Adsorption is a surface phenomenon in which a fluid (gas or…
Landfill Gas Processing: Plant-Design Considerations
There are several technologies used in the disposal of landfill gas (LFG). Here are some key elements that can guide engineers in designing an optimized LFG processing plant People generate trash. Trash is stored in landfills. Landfills contain bacteria, which…
