Oxygen Cleaning: A Validated Process is Critical for Safety

From time to time, we re-publish well-received or particularly valuable articles that have previously run on VALVEMagazine.com so that those who might have missed them will be able to catch up on the best of the best. This article, “Oxygen Cleaning: A Validated Process is Critical for Safety” initially ran on April 20, 2015.


Industrial oxygen is used for many purposes: in a basic oxygen furnace for making steel, water pollution countermeasures, including sewage treatment, habitability and superfund site rehabilitation, and chemical processes such as production of vinyl chloride, nitric acid, epoxyethane and hydrogen peroxide. It is also used for medical treatment, life support in harsh environments and industrial gasses for welding and other processes.

The production of oxygen has risen from approximatey 470 billion cubic feet in 1991 to over 1.5 trillion cubic feet in the U.S. and more than 4 trillion cubic feet globally in 2014.


Where Valves Are Used: Everywhere, Part 2

The valve industry is truly broad and diverse; valves are found in our homes, our offices, under our streets and in all our factories and plants. VALVE Magazine’s fall print magazine covered some of those industries, including water works and wastewater, the power industry, oil and gas production, offshore industries, pipelines, refineries, chemical processing, liquified natural gas and commercial buildings. This article continues that coverage.

Cybersecurity for Process Control

Security for any process plant has always been an issue. Before there was connectivity, there were threats of physical damage, and then the security of data from physical attacks. However, there had to be actual physical access to a device or hard copy of information.

Now, hackers can remotely access one device and take over an entire eco-system. According to Sean Peasley of Deloitte in a presentation at VMA’s 2018 Market Outlook Workshop, this is partly due to the fact that the internet was not built with security in mind; it was built for speed and availability.

Peasley noted that one-third of enterprises report using the Internet of Things (IoT), with another third planning to do so, primarily to enable predictive maintenance and to track asset condition and operating performance. Close to 50% of manufacturers use mobile apps to do this, and 75% of manufacturers use Wi-Fi networks to transmit data to/from connected products. Many companies even use sensor-equipped wearables to ensure worker safety and improve labor efficiency and utilization.

Carbon Capture and Storage: Why and How?

Carbon (CO2) capture and storage (CCS) is a series of processes targeted at reducing CO2 emissions from industrial processes, thereby preventing large amounts of CO2 from being released into the atmosphere. The CCS chain in recent years has been expanded to carbon capture utilization and storage (CCUS). This has given large industry emitters the benefit of possible utilization of CO2 to positively influence their cash flow.

Some of the large industrial sources of CO2 emission are highlighted below and include crude oil production and refining, natural gas production and processing, combustion process plants like power plants, and manufacturing industries including, but not limited to, iron and steel production, aluminium production, chemical industry stone and clay industry (which includes cement and the pulp and paper industry). CO2 emissions can come from both their process/technology unit and heat generation units.

Can Valves Mitigate Flooding from Severe Weather Events

Hurricanes Harvey and Irma have certainly been a test for infrastructure, and while flooding seems inevitable under such extreme conditions, there are valuable lessons to be learned from these two storms.

Pipelines

The biggest concern for people outside the affected area following Hurricane Harvey’s assault on the Houston area was the disruption in supply of gasoline and resulting high prices. Approximately one-sixth of total pipeline mileage in the U.S. is in Texas. Many of those pipelines start or end on the Gulf Coast, where about 35 major refineries are located.
