The present invention is concerned with degassing processes, and more specifically with a degassing apparatus and method for removing hydrogen sulfide and hydrogen polysulfides from liquid sulfur in a rapid and efficient manner to result in low residual hydrogen sulfide and hydrogen polysulfide levels. Utilizing a rotodynamic degassing pumping unit, a first fluid, typically in the liquid phase, is pumped or drawn under pressure or vacuum, while a second fluid, typically in a gaseous phase, is pumped or drawn under pressure or vacuum into the first fluid, effecting a chemical reaction. A rotary impeller having a plurality of blades is presented at a submerged location in the liquid sulfur surrounded by a draft-tube. The rotor (impeller) is divided into three distinct blade sections: a) a radial flow section; b) a mixed flow section; and c) an axial flow section. An overflow weir controls the depth of the liquid inside the degasser's housing. The overflow weir includes a corrugated type cross-section, comprising segments split longitudinally and welded lengthwise. The “wavy” or sinusoidal cross-sectional shape or trapezoidal or triangular shape (extending radially inwards) increases the length of the weir, which in turn minimizes the head required, and maximizes the capacity. A novel rotor bearing design is introduced as a means to mitigate excessive deflection of the main shaft. The design removes one of the two rotor bearings of the prior art and places two immersed bearings down the shaft.

A method and mechanism for initiating an emergency stop for an unattended railcar is disclosed. The method may include using a trip arm placed alongside the railway tracks at a designated stop point that may contact a portable trip-cock lever arm that extends out beyond the perimeter of the railcar if the railcar reaches the stop point as it moves along the track. The trip-cock lever arm may be attached to a valve that is connected to the pneumatic brake system of the unattended railcar. As the trip-cock lever arm rotates, the valve may open to release the air pressure in the pneumatic brake system causing the brakes to engage the wheels causing the railcar to stop.

A portable apparatus for producing sulphur granules includes a granulator with a rotatble drum having distinct zones for seed generation and product growth. The seed generation zone has an intense water spray pattern for each sulphur spray nozzle with intersecting water sprays to solidify molten sulphur and create seeds. The growth zone has a moderate, non-intersect-ing water spray pattern to allow sulphur nozzles to coat and grow a curtain of seeds into granules. The granulator's exhaust air is filtered either by a heated cyclone separator to recapture residual sulphur particles and moisture before venting, and/or by a granular air filter which uses the produced granules to filter the granulator's exhaust air. A two piece collar enhances maintenance of the granulator's drive system.
