Description
Technical field
The invention belongs to the technical field of Rubber Chemicals Industries sulphur recovery, particularly catalyst for sulphur selects for use and filling method.
Background technology
Domestic petrochemical system reclaims the production equipment of sulphur from sulphur-bearing crude and Sweet natural gas more, when producing accelerator M BT (dimercapto benzothiazole) and accelerator D PG (vulkacit D) because of it in the Rubber Chemicals Industries, and H in addition
2The S sour gas generates; Because of each reactor intermittently outwards discharges sour gas, the tolerance fluctuation is bigger, and composition is very complicated, and Crouse's recovery sulphur production equipment of Rubber Chemicals Industries practical application is simpler and cruder, and efficient is lower.2006 in the chemical plant, Shandong, take the lead in having adopted novel technique in Rubber Chemicals Industries, designed super claus plant, special in the composition of the sour gas characteristics different with petrochemical industry, made the catalyzer and the catalyst loading method of three reactor to measure.Device went into operation in 2007, proved the purpose that has reached energy-saving and emission-reduction, develops a circular economy and curbed environmental pollution, H through 1 year real running
2The S sour gas reclaims transformation efficiency 99.6%, has not only improved environment, has avoided pollution, and obtained favorable economic benefit and social benefit.
Summary of the invention
Technical problem to be solved by this invention: the invention provides a kind of the selecting for use and filling method of catalyst for sulphur of sulfur recovery facility of Rubber Chemicals Industries, according to the H of Rubber Chemicals Industries
2The composition of S sour gas is selected suitable catalyst for sulphur for use, improves the sulphur transformation efficiency of sulfur recovery facility.
Technical scheme of the present invention:
A kind of filling method of Rubber Chemicals Industries catalyst for sulphur is characterized in that, three tier structure reaction of Salmon-Saxl device is filled catalyst for sulphur respectively, and the catalyzer height in the three tier structure reaction of Salmon-Saxl device is 800mm; One-level convertor top filling 1m
