Abstract
Sulfur seeds can be produced by spraying liquid molten sulfur into a moving stream of liquid from a sulfur spray nozzle. Some of the sulfur may pass through the liquid and some of the sulfur may be entrained in and carried by the stream of liquid, or all the sulfur may be entrained in the stream of liquid. The sulfur droplets entrained in the stream of liquid can be carried by the liquid to a cooling tank, which can be a spiral dehydrator tank with an angled bottom and a screw conveyor. The opening may be made on the bottom surface of the screw conveyor housing of the spiral dehydrator tank so that liquid is drained from the screw conveyor when the sulfur seeds are moved from the tank to the drum. The screen can be disposed across the opening and the drain trough is attached to the screw conveyor housing to capture any liquids and solids that travel through the screen. The cleaning line can assist in moving the solids passing through the screen.
Description
This application is a continuation in part of pending U.S. Application No. 12 / 953,512, filed November 24, 2010, which is incorporated herein by reference in its entirety for all purposes.
The present invention relates to the field of converting molten sulfur (or sulfur) into a sulfur seed using a moving liquid.
Sulfur is an important industrial product most commonly produced in the form of molten liquid as a by-product from oil and gas refining. Most liquid sulfur is solidified into various "forms" such as granules, tablets or prills to facilitate transportation and use. The various forms are produced commercially by different processes. The granules are produced by enlarging the "seeds" in the granulating drum; The tablets are formed by placing sulfur droplets on a continuous stainless steel belt; Frills are produced by dropping liquid sulfur in a water bath of cooling water. While tablets and frills are produced by solidifying single sulfur droplets, the production of granules requires "seed" particles to begin the growth process.
The criteria for evaluating sulfur products have been established by the Sulfur Development Institute of Canada (SUDIC). Under these criteria, the shape and particle size distribution of the sulfur forms is generally spherical with a diameter between 2 mm and 6 mm. Sulfur forms are classified as "high quality product" or "standard product" depending on shape, particle size distribution, moisture content, and friability. Sulfur granules and tablets meet the high quality product specifications in all respects. Wet frills do not meet the high product specification for moisture and are therefore considered "standard product ". It will be appreciated that the sulfur seed may be sulfur particles in industry and the sulfur particles should be sulfur granules requiring further growth to achieve maximum commercial value. It is generally considered that the sulfur seed is less than 2 mm in diameter.
The three commercial forming processes also differ in the way that heat is removed to effect the sulfur melting and cooling of the solid particles. In drum granulation, the sulfur is cooled by transferring heat to the atmosphere inside the drum, and the temperature is controlled by evaporation of the water droplets that are sprayed onto the drum. The tablets are cooled by spraying water down the stainless steel belt and the stainless steel belt is in turn cooled by evaporation in the cooling tower. The wet prills are cooled by transferring heat to the water tank, which is in turn cooled by evaporation in a cooling tower.
U.S. Pat. No. 4,213,924 to Shirley discloses a method for producing sulfur granules in a rotary drum with lifting flights wherein the lifting flights lift the seeds and the seeds then fall off the flights as curtains and then the seeds are coated with a spray of liquid sulfur To produce sulfur granules. The product discharged from the drum is screened and seeds that are not properly grown return to the conveyors and are cooled or heated before they are recycled into the input end of the drum. Also, No. 4,213,924 (Shirley) proposes to crush the oversized product discharged from the granulating drum and recycle the crushed material as a seed or as a recycled material in the drum. A disadvantage of pulverization is that dust is generated which can be released into the surrounding environment. Dust can be explosive and / or unhealthy. Also, the ground product is not constant in size or is not a spherical shape.
In the past, it has been proposed that the fans force the circulation of air through the poling curtains for improved cooling. The more cooled sulfur products are less brittle and tend to be less susceptible to "caking" or " clumping "upon storage. However, the fans become unbalanced due to the sulfur accumulated on the blades.
U.S. Pat. 4,272,234 (Tse) suggests that sulfur seeds are formed in the granulation drum by raising the temperature of the rotating bed of sulfur particles for a short period of time. The sulfur sprayed onto the poling particles in a particular region of the drum is not immediately solidified but remains soft or in a fired state on the surface of the particles and when the particles are tumbled in the bed the polishing action of the other particles is about 0.1 It is proposed to break off into soft coatings of small pieces having a diameter in the range of about 1.0 mm to about 1.0 mm.
U.S. Pat. No. 4,507,335 (Mathur) discloses a process for producing sulfur sulphide particles in a granulated drum, in which the liquid sulfur droplets present at the outer edges of a thin flat spray plume are solidified into the seeds before contacting the poling curtain of solid sulfur particles, Lt; / RTI > U.S. Pat. No. 5,435,945 (De Paoli et al.) Proposes to generate sulfur seeds in the granulation drum by crossing a molten sulfur spray with a water spray or by generating a spray of sulfur droplets to allow solidification in the atmosphere within the granulation drum do.
The disadvantage of producing seeds in the granular growth drum is that the conditions required in the drum for optimal granule generation are not the same as those required for optimal seed generation. This typically requires a skilled technician to monitor and operate the system.
U.S. Pat. No. 7,638,076 (Koten) discloses a process for producing solid frills by passing molten sulfur through an overflow filter, a drip tray with a heating channel, an injection conduit for transfer to a cooled zone of the water, Curved screen and vibrating screen.
There is a need for a method and system for more efficiently generating sulfur seeds for use in growth into sulfur granules. It is possible to substantially eliminate the need to screen the drum output and recycle the under-sized product by conveyors back to the drum input end, as the sulfur granules are produced in a one-pass continuous growth process through the granulation drum at reasonably high production rates It would be desirable to control the size distribution and generation rate of the seeds in a manner that directly corresponds to the growth requirements to make them grow. There is also a need to improve the rate at which the granules are cooled in the drum to realize improved product quality and higher production rates.
Sulfur seeds can be produced by spraying liquid molten sulfur into a moving stream of liquid, such as water or other cooling medium, from a sulfur spray nozzle. The spray nozzle can spray molten sulfur in the same direction as the flow of the moving liquid. In one embodiment, a portion of the sulfur may pass through the liquid and a portion of the sulfur may be entrained in and carried by the stream of liquid. Sulfur droplets passing through the stream of liquid may fall into the cooling tank. In yet another embodiment, all of the sulfur is maintained in a stream of liquid. The sulfur droplets entrained in the stream of liquid can be carried by the liquid to the cooling tank. The cooling tank may be a spiral dehydrator tank having an angled bottom and a screw conveyor and in this case the screw conveyor may transport the seeds to a granulating drum used to grow the seeds from the bottom of the tank into the sulfur granules. In one embodiment, the spreading trough may be located at an elevation higher than the cooling tank to provide a broad stream contact of liquid to the sulfur spray so that the stream is not present in the container upon contact with the sulfur spray. The water may be supplied to the spreading trough from the wet scrubber.
The opening may be made on the bottom surface of the screw conveyor housing of the spiral dehydrator tank so that liquid is drained from the screw conveyor when the sulfur seeds are moved from the tank to the granulating drum. In one embodiment, the opening may be substantially the same length as the screw conveyor housing. The screen can be disposed across the opening and the drain trough is attached to the screw conveyor housing to capture any liquids and solids that travel through the screen. The screen size may be selected to minimize the number of solids passing through the screen. The drainage trough may be angled to support transport of the contents returning to the spiral dehydrator tank. In one embodiment, the pipe can carry the contents of the drainage trough to a spiral dehydrator tank. In an embodiment, a liquid, such as water, can be supplied to the drain trough to ensure that solids passing through the screen into the trough are transferred to the spiral dehydrator tank. The water may be supplied from a cleaning line bypassed from the pipe connected to the spiral dehydrator tank to the wet scrubber.
A better understanding will be given by way of example only and as a result of the following detailed description of the various disclosed embodiments in non-limiting Figures:

The sulfur nozzles used to grow the seeds in the drum can produce a flat spray pattern with tapered or flat edges. A plurality of sulfur nozzles may be used on the spray headers or manifolds so that the spray pattern of adjacent nozzles may overlap to provide a certain coverage across the falling curtains in the axial direction. The spray pattern may have spray angles of between 15 and 110 degrees. A nozzle that produces a uniform flat spray pattern can provide a constant spatial density of droplets across the entire flat spray pattern. It may have spray angles from 15 ° to 110 °. A thin rectangular spray pattern can provide a minimum overlap between adjacent nozzles in a constant coverage. A uniform flat spray pattern can be created by deflected type nozzles. A spray pattern of medium sized droplets is formed by the liquid flowing across the deflector surface from the rounded orifice. The spray angles may be between 15 ° and 150 °. The nozzle may be a rounded orifice, but may have a large free passage configuration that reduces clogging. Narrow spray angles provide higher impact, but wide angle versions produce lower impact.

Angled or screw shaped flights can advantageously increase the exposure of hot seeds and granules to the cooling atmosphere by minimizing the height of the beds of seeds and granules in the drum. The more cooled products are less friable and tend to be less sensitive to "caking" or " clumping "during storage. The larger the helical flights move the larger granular volume, the larger the volume is produced. This always keeps the bad depth at a constant height (slightly above the flights) below the drum. As a result, virtually all granules remain in circulation to the curtains where they are effectively cooled. Without volume acceleration, the extra volume can simply increase the bed depth and thus rather the bed is not lifted and is simply tumbled to make cooling less effective.

The embodiments described above can permit control of the size distribution and generation rate of seeds produced outside the granulating drum which enables one-pass growth cycles through drums (no seed recycling) at high production rates (over 1500 tonnes per day) have. This capability eliminates the need for an output screen and a lower side recycle conveyor (lower capex and operating cost). The system can provide an improved production quality and an increase in unit production rate made possible by improved cooling of granules (i.e. improved exposure of the granules to the sweep air where cooling by itself is maintained by water evaporation). This can be accomplished by unaligned or staggered lifting flights. This can provide a more curved path for air flow around the poling curtains.
Per minute drum revolutions (RPM), the poling curtains can be selected to fill at least 75% of the granulating drum volume. The flights directly attached to the drum on lines that are attached to the rib members or not parallel to the drum rotational axis are moved to the discharge end at a gradual faster rate corresponding to the sulfur mass introduced as a spray, Quot; configuration, the amount of granules tumbling in the bed without cooling can be kept to a minimum. Substantially constant product temperatures can be maintained, among other things, for changes in key operating parameters such as sulfur production rates, temperature of liquid sulfur and sulfur products, and ambient temperature and humidity. This can be achieved by adjusting the air flow rate through the drum by changing the speed of the fan. The fan speed can be determined by the control system or process using inputs from various devices.
Improved particle size distribution of the product by including a gap between the flights and the drum shell allowing for preferential spraying of finer granules and seeds as a result of discharging coarse granules from the most distal curtains from the sulfur spray nozzles Control may be possible. There is a possibility that the seeds may adhere to or prevent the lifting flights originating from the seed input end of the drum, since the seed particles may be wet. This can be mitigated by installing a flexible membrane around the inner wall of the drum and removing flights at the first 2 to 4 feet of the drum. The membrane, which may be non-rigid, can be bent as it rotates against the top of the drum, allowing the lumps to fall back into the bed. A normal air flow with no water spray passing through this area can dry the seeds before entering the normal flight section of the drum.
