Abstract

The invention discloses an insoluble sulfur production system and a production method. The production system comprises a polymerization kettle, a quench tower, a washing filter and a dryer, a discharge port of the polymerization kettle communicates with a feed port of the quench tower through a pipeline, a discharge port of the quench tower communicates with a feed port of the washing filter through a discharge pump through a pipeline, and a discharge port of the washing filter is connected with a feed port of the dryer through a pipeline. According to the production system disclosed by the invention, granulation, curing, extraction and crushing processes are integrated, continuous quenching, curing and the like of the polymerized sulfur are realized, and the technological process is simplified. According to the method, the operation process is shortened, the purity, thermal stability and yield of the product are ensured, the blockage of a sulfur particle system is avoided, and the production process has the characteristics of safety, reliability, simple equipment and operation, low operation cost, obvious energy-saving effect and the like.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry and relates to a production method and production system of insoluble sulfur. Background technique [0002] With the sharp increase in oil consumption, global oil resources are increasingly scarce, and the quality and inferiority of refinery raw materials are becoming more and more serious. At the same time, environmental protection regulations in various countries are becoming stricter, and the control of total sulfur content in petroleum products and natural gas is becoming more stringent. Therefore, the capacity of sulfur recovery units in major refineries and natural gas purification plants has increased rapidly. The domestic and foreign markets of this common sulfur have become saturated, so the price is low. How to provide high value-added sulfur products that are in short supply in the market has become the focus of relevant enterprises. [0003] Insoluble sulfur is a high-...
