Guidance Document Cryogenic Liquids
Guidance Document Cryogenic Liquids [This is a brief and general summary. Read the full MSDS for more details before handling.] Introduction: All cryogenic liquids are gases at normal temperature and pressure. The liquids are formed by cooling the gases below room temperature, followed by compression which liquefies them. Cryogenic liquids are kept in the liquid state at very low temperatures. Cryogenic liquids have boiling points below -73°C (-100°F). The most common cryogenic liquids currently on campus are liquid nitrogen, liquid argon and liquid helium. The different cryogens become liquids under different conditions of temperature and pressure. But all have two very important properties in common. First, the liquids and their vapors are extremely cold. The risk of destructive freezing of tissues is always present. In addition, when they vaporize the liquids expand to enormous volumes. For example, liquid nitrogen will expand 696 times as it vaporizes. Vaporization in a sealed container could rupture the vessel. Vaporization in an enclosed workspace could cause asphixiation by displacing air needed to support life. All of the cryogenic liquids on campus are inert, colorless, odorless, non-corrosive and non- flammable. Not all cryogens fit this description. Special permission would be required to use other cryogenic liquids. Liquid oxygen could produce an oxygen-rich atmosphere which could accelerate combustion of other materials. Liquid hydrogen, liquid methane or liquefied natural gas could form an extremely flammable mixture with air. Liquid carbon monoxide is extremely toxic and extremely flammable. Cryogenic liquids are received from the vendor in special vacuum jacketed cylinders, which allows for storage of the liquefied gas for a long time. -

Paving the Way for LNG
Plants, terminals and equipment for the entire LNG value chain Paving the way for LNG Making our world more productive 2 LNG value chain Introduction Driven by increasing natural gas demand and decreasing costs along the whole LNG value chain (due to significant economies of scale, improvements in technologies, etc.), investments in LNG infrastructure are growing rapidly in the last years. LNG has turned from being an expensive and regionally traded fuel to a globally traded source of energy with rapidly diminishing costs. In China, Norway and lately in particular in the US, petroleum fuels With more than 125 years of comprehensive experience in the Linde offers innovative and economical solutions for the entire LNG have been successfully substituted by LNG in various applications, handling of cryogenic liquids, Linde Engineering has a track record in value chain and has more than 40 years experience in designing, mainly for heavy trucking, remote-power generation and marine the design and performance of a wide range of natural gas projects building and operating LNG plants and proprietary cryogenic fueling. Today the volumes are still relatively small, however studies including upstream natural gas liquids recovery (NGL plants), feed equipment. indicate substantial demand for additional domestic LNG capacities in gas pre-treatment and liquefaction, transport and distribution of LNG many countries. These include the entire Baltic Area (ECA) and South regasification in both LNG import and export terminals. East Asia. As a consequence, an appropriate infrastructure consisting of small- to mid-scale LNG liquefaction plants, import terminals and Linde Engineering is well recognised as a reliable technology refuelling stations will be built up and/or expanded. -

1 Introduction
1 1 Introduction The history of industrial gases is inextricably linked to the rapid pace of industri- alisation that marked the nineteenth century. The large-scale generation of certain gases opened the door for new types of technologies and production processes. Acetylene, for example, was discovered by E. Davy in 1836. A signifi cant landmark followed in 1862, when F. Wöhler succeeded in producing acetylene from the reaction between calcium carbide and water. Then, in 1892, T. L. Wilson and H. Moissan discovered a process for generating calcium carbide in an electric furnace. This paved the way for industrial-scale production of acetylene in 1895 (see also Section 8.2). Initially, acetylene was mainly used for lighting purposes due to its bright fl ame. Later, its high combustion temperature in oxygen prompted development of autogenous cutting and welding technology, starting in 1901. An even more important step from today’s perspective was the liquefaction of air by Carl von Linde, marking the birth of an entirely new industry. C. v. Linde employed the Joule–Thomson effect, decreasing the temperature of the gas by adiabatic expansion. In 1895, he achieved continuous generation of liquid air at a yield of three litres per hour using a laboratory plant [1.1]. The following years saw the construction and delivery of the fi rst small commercial air liquefaction plants. Figure 1.1 shows a typical early air liquefi er (ca. 1899).

How Liquid Helium and Superconductivity Came to Us
IEEE/CSC & ESAS EUROPEAN SUPERCONDUCTIVITY NEWS FORUM (ESNF), No. 16, April 2011 Heike Kamerlingh Onnes and the Road to Liquid Helium Dirk van Delft, Museum Boerhaave – Leiden University e-mail: [email protected] Abstract – I sketch here the scientific biography of Heike Kamerlingh Onnes, who in 1908 was the first to liquefy helium and in 1911 discovered superconductivity. A son of a factory owner, he grew familiar with industrial approaches, which he adopted and implemented in his scientific career. This, together with a great talent for physics, solid education in the modern sense (unifying experiment and theory) proved indispensable for his ultimate successes. Received April 11, 2011; accepted in final form April 19, 2011. Reference No. RN19, Category 11. Keywords – Heike Kamerligh Onnes, helium, liquefaction, scientific biography I. INTRODUCTION This paper is based on my talk about Heike Kamerlingh Onnes (HKO) and his cryogenic laboratory, which I gave in Leiden at the Symposium “Hundred Years of Superconductivity”, held on April 8th, 2011, the centennial anniversary of the discovery. Figure 1 is a painting of HKO from 1905, by his brother Menso, while Figure 2 shows his historically first helium liquefier, now on display in Museum Boerhaave of Leiden University. Fig. 1.

HKO’s historical helium liquefier (last stage), now in Museum Boerhaave, Leiden. I will address HKO’s formative years, his scientific mission, the buiding up of a cryogenic laboratory as a direct consequence of this mission, add some words about the famous Leiden school of instrument makers, the role of the Leiden physics laboratory as an international centre of low temperature research, to end with a conclusion.
