<br>
<p class="p__0">Piston compressors work on a simple theory. Rick Turnquist, with RIX Industries instructs, "The piston in a big cylinder presses a fixed quantity of gas into a smaller sized cylinder, thus triggering a pressure increase. This is based on the ideal gas law, which in shortened kind is: PV=n, T (pressure x volume = Moles of gas x temperature).</p>

<p class="p__1">These might be: a special valve style; unique piston ring products; overlapping piston ring design to minimize leak; lower compression ratios; or cylinder and head castings might need to be impregnated to stop leakages caused by casting porosity. In addition, the grade of steel utilized in the compression end parts may require to be changed." Hydrogen, like all gases, is heated up by compression.</p>

<p class="p__2">The largest end-users of multi-stage reciprocating piston compressors are refineries and chemical plants. Customers consist of such companies as Air Products, Praxair, and Chevron Research. These compressors are likewise utilized for some refueling applications, for syngas, pilot plants, and lab R&amp;D. Centrifugal Compressors Centrifugal compressors are seldom used for hydrogen applications due to the particle's low molecular weight.</p>

<p class="p__3">Barbers Nichols Inc. ( You Can Try This Source ), designer and maker of specialized turbo-machinery, has made cryogenic H2 centrifugal compressors for two applications. These two applications involve sub-cooling H2 by drawing down liquid boil-off gas pressure listed below atmospheric. Jeff Shull, with Barber Nichols, explains that "this develops a more thick liquid that can then be utilized in a rocket more effectively (uses up less space and reduces overall weight).</p>
<br>
<p class="p__4">BNI's H2 cryogenic compressors utilize a motor and bearings operating at space temperature with an overhung impeller on a hollow shaft to reduce heat input to the fluid. No dynamic seals are utilized so styles are hermetic. BNI has also provided a number of H2 circulators in supercritical applications (supercritical H2 is more like a liquid than a gas, however) for cryogenic cooling." Pumps utilized in conjunction with LH2 are liquid positive displacement pumps.</p>
