Predictive monitoring of critical rotating and non-rotating equipment is important for successful plant operation. Two end users benefited from this type of real-time monitoring of their critical assets. They were alerted to small abnormalities that could have escalated to expensive interruptions, helping maintenance personnel take a more preventive approach.

The Middle East and North Africa are likely to see an annual growth in power demand of 6 to 8 percent—roughly three times the world’s growth rate. Satisfying this surge in demand will require regional governments to leverage diverse power sources such as solar, oil, natural gas and coal. Governments have increased incentives for renewable energy sources within the region.

Liquefied natural gas (LNG) is natural gas in a liquid form that is clear, colorless, odorless, non-corrosive and non-toxic. It is produced when natural gas is cooled to minus 259 F (-161.66 C) through a process known as liquefaction.

The North South Interconnection System Project (NSISP) is one of South Australian Water Corporation’s (SA Water) biggest infrastructure projects in the Adelaide metropolitan area. SA Water built the $403 million project to connect the north and south drinking water distribution systems and to increase access to a desalination plant.

All pumps should be tested regularly, but wastewater pumps are at the top of the list because they are especially susceptible to changing system conditions. Even if a pump operates at its best efficiency point (BEP) at startup, many conditions will change during its lifetime of operation, including:

The U.S. infrastructure for the transmission, treating, storing and distribution of water requires drastic changes because of its increasing inability to sustain the new demands for potable water and water recycling. The majority of water treatment plants in the U.S. are suffering from old infrastructure technology, limited processing capacity and unpredictable weather.

An article in the October 2013 issue of Pumps & Systems discussed how to minimize leaks by applying proper design and material-selection standards. This article details new codes that have been established because the International Organization for Standardization (ISO) is currently updating certain standards, including ISO 15848 Parts 1 and 2.

Process industries rely on vast piping systems and connected equipment that must be sealed safely to protect their employees, profits and the environment. Safely sealing these systems can be challenging, but failure to do so can result in serious problems—including injury and death.

In my last column (Pumps & Systems, October 2014), I explained that a capacitor’s current is totally out of phase with that of a motor’s magnetizing current.

I received a lot of feedback on my column “How Much Energy Do Pipes Remove?” in the September issue of Pumps & Systems.

A reciprocating power pump, as depicted in Figure 1, is a displacement machine. It has characteristics that are different than a centrifugal pump.
