Modular Helium Production

Modular Helium Reactor - an overview | ScienceDirect Topics

In this process, natural gas and coal are used as the source of carbon, while heat and electricity are provided by an advanced type of nuclear energy source called a Modular Helium Reactor (MHR) (Adams and Barton, 2011). This forms the coal-gas-and-nuclear-to-liquids (CGNTL) process, which can be better both environmentally and economically than coal-to-liquids (CTL), coal-and-gas-to-liquids (CGTL), …

For electricity and hydrogen production, an advanced reactor technology receiving considerable international interest is a modular, passively-safe version of the high-temperature, gas-cooled reactor (HTGR), known in the U.S. as the Modular Helium Reactor (MHR), which operates at …

Helium Production | North American Helium

Helium has historically been produced as a by-product of certain conventional natural gas projects (less than 3% of natural gas deposits have more than trace amounts of helium), and those sources account for the bulk of helium supply today.

Modular Helium Reactor (MHR) for Oil Sands Extraction

•The Modular Helium Reactor (MHR) is a viable option for providing carbon-free process steam and electricity for oil sands extraction •MHR application for steam production for a 30,000 barrels per day SAGD plant saves ~29 Million SCF of natural gas usage …

High Temperature Gas Reactors - an overview ...

As described in Elder and Allen (2009), the GA concept, from the US-DOE NERI (Nuclear Energy Research Initiative), is designed around the modular helium reactor of 600 MW thermal energy output per unit. The integrated hydrogen production site will include four nuclear reactors, totaling 2.4 GW thermal power generation.

Helium production in the United States - Wikipedia

Helium production in the United States totaled 73 million cubic meters in 2014. The US was the worlds largest helium producer, providing 40 percent of world supply. In addition, the US federal government sold 30 million cubic meters from storage. Other major helium producers were Algeria and Qatar.

Helium - Wikipedia

The principal impurity in Grade-A helium is neon. In a final production step, most of the helium that is produced is liquefied via a cryogenic process. This is necessary for applications requiring liquid helium and also allows helium suppliers to reduce the cost of long distance transportation, as the largest liquid helium containers have more than five times the capacity of the largest gaseous helium tube trailers.

Nuclear Hydrogen Thermochemical Production of Hydrogen ...

Nuclear Production of H2 Appears Attractive • A large and growing market for H2 exists that nuclear energy could serve – H2 for oil refineries is the likely first market and can provide a bridge to the future Hydrogen Economy • The Modular Helium Reactor coupled to the Sulfur-Iodine water-splitting cycle is an attractive system:

The modular leak detector for easy and quick integration

The modular design and small footprint of the ASI 35 enables it to be easily integrated into existing systems. A particular feature is the leak detectors ease of use. Its high reliability and short maintenance times are crucial for avoiding production downtimes and quality problems.

Test Plan for Helium Circulators (PHTS, SCS, SHTS)

Dec 09, 2008 · Further to this, in 1993, Howden also designed the helium circulator for the New Production-Modular High Temperature Gas-cooled Reactor (NP-MHTGR) program. The selected design had radial flow impeller, oil-bath lubricated bearings, submerged motor drive, rotational speed of about 3000 rpm and a maximum power level of approximately 6 MWe.
