New Opportunities For NGVs From Tighter Ozone Standard

New Opportunities for NGVs from Tighter Ozone Standard

  • November 19, 2015

Ground-level ozone is a growing problem in many cities, especially on the US west coast. As noted by the EPA, it causes respiratory problems like throat irritation, tightness in the chest, and increased occurrence of asthma attacks. That’s why, on October 1st2015, the National Ambient Air Quality Standard was lowered from 75 to 70 ppbn. This has implications for the fuel burnt in automobile and truck engines, and supports increased use of compressed natural gas (CNG.) CNG for vehicles is delivered through specially-designed filling stations, which are good applications for ChemTec flow monitors and excess flow valves.

Process Cooling: Keeping Manufacturing Competitive

Process Cooling: Keeping Manufacturing Competitive

  • November 10, 2015

Metal casting and plastic molding are near-net shape manufacturing processes. Liquid material fills a die, solidifies and is ejected. A few quick finishing operations later and a precision part is ready for shipping or assembly. The key to making money though is doing this quickly. Molding and casting machines are expensive, as are the dies, so throughput and utilization must be maximized. That means chilling the filled die as fast as possible, and that takes sophisticated cooling systems.

When hurricanes, wildfires or simple electrical system overloads cut the power to cell phone towers, diesel backup generators typically are the only way to keep the calls coming. But diesel requires maintenance and man-hours. An alternative, hydrogen, requires much less maintenance and man-hours to maintain.

Public transportation across the country has been using CNG for decades, with about 12-15% of public transit buses in the U.S. currently running on natural gas (either CNG or LNG – liquefied natural gas). That number is growing, with nearly one in five buses on order today slated to run on natural gas. States with the highest consumption of natural gas for transportation are California, New York, Texas, Georgia, Massachusetts and Washington, D.C.

Options For Detecting Gas Leaks

Options for Detecting Gas Leaks

Gas escaping from pipework needs to be detected quickly. Depending on the type of gas, the consequences range from merely wasteful to fatal. Leaking gas can be environmentally damaging, it can create an explosion risk, and it can even kill thousands of people, as happened in the Bhopal chemical plant disaster.

Water Quality A Key Factor In PV Manufacturing

Water Quality a Key Factor in PV Manufacturing

  • August 7, 2015

With supply exceeding demand, producing the silicon panels for photovoltaic (PV) power generation has been an intensely competitive business for several years. There are however reports that a turnaround is underway. Solar industry observers like Greentech Media (GTM) state that with capacity growing only slowly, manufacturers are beginning to see signs of better margins ahead.
