Complete equipment and method for drum sulfur granulation with cooling flow channel

Abstract

The invention provides complete equipment and a method for drum sulfur granulation with a cooling flow channel. The complete equipment comprises a liquid sulfur distributor, a cooling granulation drum, a cooling water circulation system and a scraper, wherein the liquid sulfur distributor can distribute and drop liquid sulfur produced by an upstream device to the outer surface of the cooling granulation drum; the cooling granulation drum can rotate around a central shaft, the outer surface of the cooling granulation drum can be used for cooling liquid sulfur to form sulfur particles, and a cooling flow channel is arranged in the cooling granulation drum and can be used for cooling the outer surface; the cooling water circulation system is in circulation communication with the cooling flowchannel and can provide cooling water for the cooling flow channel; and the scraper is in scraping connection with the outer surface of the cooling granulation drum and can be used for scraping sulfurparticles on the outer surface of the cooling granulation drum. The outer surface of the cooling granulation drum is adopted for sulfur granulation, and the interior of the cooling granulation drum communicates with the cooling water system, so sulfur is not in direct contact with cooling water, and the water content of a product is low.

Description

technical field [0001] The invention relates to a sulfur granulation equipment. Background technique [0002] The sulfide contained in crude oil and natural gas can be removed to form liquid sulfur. Since the melting point of sulfur is 115°C, it will crystallize and solidify at room temperature, which brings difficulties to storage and use. Therefore, the sulfur recovery unit is equipped with a granulation section to convert the recovered Liquid sulfur is made into solid products to facilitate downstream transportation and use. [0003] At present, there are three main sulfur granulation processes commonly used, namely rotary steel belt granulation, rotary drum spray granulation and underwater wet granulation. [0004] Rotary steel belt granulation adopts steel belt for cooling. During granulation, liquid sulfur drips onto the front of the continuously running steel belt. Cooling water nozzles are installed on the back of the steel belt. The nozzles continuously spray cooli...

AI Technical Summary

Problems solved by technology

[0006] 1. The operating area of ​​the rotary steel belt is relatively large, and the construction cost is relatively high;

[0007] 2. The steel belt will be worn during the rotary operation and needs to be replaced regularly;

[0008] 3. The cooling water is lost during the injection process and cannot be completely recycled

[0011] 1. During the granulation process, the sulfur droplets are in direct contact with the cooling water, and the water content of the product is relatively high;

[0012] 2. During the granulation process, the sulfur particles continuously collide in the drum, which will generate a lot of dust;

[0013] 3. The cooling water cannot be recycled during the granulation process, and the consumption of public works is high

[0018] 3. Cooling water forming tank and auxiliary equipment need to be installed, which occupies a large area
