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.
The Jordan, Knauff & Company (JKC) Valve Stock Index was up 10.4 percent over the last 12 months, while the broader S&P 500 Index was up 17.8 percent. The JKC Pump Stock Index was up 26.5 percent for the same time period.1
Valve and pump packing performance improvement is usually approached from a procedure or specification process. Engineering and purchasing determine the parameters for the plant and create a procedure for selecting the packing type and how it is used. At many plants, this document is not often referenced or updated.
