It was the worst accident in Houston history. On May 11, 1976, at 11:08 in the morning, a tank truck carrying 7500 gallons of anhydrous ammonia lost control, crashed through a guardrail and careened off a ramp to the freeway below. The tractor-trailer struck a column on the way down, and landed on the Southwest Freeway, rupturing the tank and releasing a deadly cloud of ammonia over the busy 610 at 59 interchange. Those who weren’t injured in the initial accident found themselves trapped in a cloud of gas and running for their lives. One person was killed in the accident and five people were killed from inhaling anhydrous ammonia. 178 people were injured from the ammonia fumes, including 78 who had to be hospitalized. The National Transportation Safety Board concluded that the probable cause of the accident was the excessive speed of the vehicle combined with the lateral surge of liquid in the partially loaded truck, which caused it to overturn.

Safurex�, developed by Stamicarbon together with Sandvik, is a family of solutions that have become the standard for enhancing urea production due to its superior corrosion resistant properties.

_x000D_

Various parts in a urea plant require different material characteristics to ensure optimal performance.

_x000D_

Therefore, Stamicarbon added two more Safurex solutions: Safurex� Star and Safurex� Degree Safurex� Star is a super duplex steel designed for the most demanding equipment of a urea plant, such as the High-Pressure Stripper�s heat exchanger tubes.

_x000D_

Safurex� Degree is a super duplex steel that has an isotropic and fine-grained microstructure, which enhances mechanical properties at very low temperatures and improves corrosion resistance with respect to cross-cut end-attack.

_x000D_

The first High-Pressure Stripper made with Safurex� Star and Degree was manufactured by Schoeller-Bleckmann, the global market leader in high-precision components made of high-alloy steel.

_x000D_

This special High-Pressure Stripper was ordered by urea producer OCI Nitrogen, one of Europe�s market leaders in mineral fertilizers.

When pressures go up to super-critical levels, there’s nothing like EST Group’s Pop-A-Plug P2 Tube Plugging System. A proven long-term performer in fossil and nuclear stations, the P2 features patented internally serrated rings designed to maintain a leak-tight seal under extreme thermal and pressure cycling.

Installation is simple: prepare the tube using the brush and size the tube with the Go/No-Go gage supplied; install the correct size plug with the hydraulic ram. The ram pulls the tapered pin through the ring, expanding it into the tube. When the proper installation pressure is reached, the breakaway pops like a pop rivet. This controlled installation force protects surrounding tubes and adjacent ligaments.

Pop-A-Plug P2 Tube Plugging System reduces downtime, eliminates welding and explosives, and will not damage your tubes, tubejoints or tubesheet. Fast, safe and simple – just “Set ‘Em and Forget ‘Em”.

Pressures up to 7,000 psi (483 Bar)

Sizes .400″ to 1.460″ (10.16mm to 37.08mm) Tube I.D.

Proven Helium Leak Tight to 1×10-10 cc/sec

The creation of nitrogen fertilizers have greatly benefited humans by increasing crop yields and ensuring food security in many areas of the world. While some places need more fertilizer, like much of sub-Sahara Africa, many places are rife with nitrogen. The overabundance of nitrogen, particularly nitrates, creates a host of environmental problems, including dead zone formation, elevation of infectious disease, drive harmful algal blooms, enhance greenhouse gas emissions, among other negative consequences. The challenge ahead is maximize the obvious benefits while minimizing the damaging effects of nitrogen use. Here, I briefly describe findings presented in a paper published in the journal Nature (“Stoichiometric control of organic carbon-nitrate relationships from soils to the sea”, April 22nd issue, 2010) that explains how nitrate accumulates from soils to the seas across earth’s biomes. Our findings represent a new framework to understand the fate of nitrate in ecosystems worldwide, which could help management strategies targeting nitrogen pollution. Visit https://www.nitrogennews.com and https://www.initrogen.org for more information on nitrogen related issues. Also, visit my personal website, https://web.me.com/philipgtaylor for more detailed information about my work in nitrogen pollution.

Answers to Diesel Exhaust Fluid (DEF) common questions. DEF is a urea-based, non-toxic operating fluid used by diesel-powered vehicles equipped with Selective Catalytic Reduction (SCR) in the U.S. to lower harmful Nitrogen Oxide (NOx) emissions and meet the EPA’s 2010 heavy-duty engine and vehicle emissions standards. Here we answer how DEF is delivered to a bulk tank and whether the type of connection to the bulk or mini-bulk storage tank matter.

Nitrogen undergoes transformations in the soil depending on the chemical composition of the nitrogen applied. Learn more about Yara at https://www.yara.com/sustainability/climate/index.aspx While nitrate is taken up directly by plants, ammonium and urea first need to be transformed into nitrate. Transformation losses are lowest with nitrate and highest with urea. All the nitrogen in the soil, whether it was applied as urea, ammonium or nitrate, ends up as nitrate before plants take it up. If nitrate is applied directly, then losses from the transformation from urea to ammonium and ammonium to nitrate are avoided.

Audio of Radiolab excerpt about Fritz Haber

This structure is one of main structures in the powder production plants in petrochemical facilities. It is very complicated and dense structure. Because of the solid handling systems used in such structures, coordination between different disciplines are very essential and there are potentially large no. of clashes exist between structure elements and the solid handling system and piping in the building. Fortunately this coordination done effectively by using BIM in model transferring between structure department and other disciplines. One of the other benefits of using this model transferring, is to see the actual size of connections. In typical projects usually, connection elements (e.g. end plates, gusset plates,..) have been ignored, which actually is one of the main source of problems, by clashing with other items. In this model at the beginning the connections have been applied by Auto Connection, so nothing missed in the coordination with other disciplines.

It is the continuation of a special project in which they demonstrate how to grow a productive rice crop in a 25 x 100-meter field on IRRI’s research farm. Here, Leigh applies urea topdressing at 29 days after transplanting and inspects the crop’s progress during abnormally cool weather for the Philippiines. Leigh’s commentary: 18 January: Fertilizing far-apart plants in chilly weather Now 29 days after transplanting, the plants are safe from harm by snails and relatively weed-free. There is the odd ugly patch. The weather has not been good in the last 10 days � rainy, cloudy, and relatively cool � and the plants show it. They have commenced tillering, but are not yet thriving. There is really no cure for unfavorable weather, but a timely topdressing will allow the plants to take full advantage of any future improvement. We applied 100 kg/ha of urea, which equates to 46 kg N/ha, onto dryish soil and irrigated within hours after this. I would give myself a 7 out of 10 for the uniformity of my topdressing. The dry soil does make it easier to see the density of granules on the ground and to adjust the application rate a little as you go. At this time, I do regret the mechanical transplanter’s 30-cm spacing between rows. Around 20, or at most 25 cm, would have been better. Currently, the 30-cm spacing looks to be a wide expanse, ready to be occupied by things other than rice, especially where we have the odd vacant site (or ‘hill’ to the purists), vacant from an imperfect transplanting process. Mother Nature hates an empty space so we will definitely need a second herbicide application. Please help us pray for sunny weather, or can you only pray for rain?
