Ruichang supplies horizontal shell-and-tube sulfur condensers for Claus sulfur recovery units. The condenser cools process gas from the upstream reaction section, condenses sulfur vapour into liquid sulfur and recovers heat through steam generation on the shell side.
Identify the condenser stage in your enquiry: after the waste heat boiler, after an intermediate catalytic reactor or at the final catalytic stage. Include the gas and steam conditions at that location.
Sulfur condensation between Claus stages
After the reaction furnace, the waste heat boiler removes heat from the hot process gas. The first condenser provides further cooling so that sulfur can be collected as liquid. Additional condensers recover sulfur after the catalytic reactors.
Gas leaving an intermediate condenser is reheated before entering the next catalytic reactor. The final condenser passes the remaining gas to the downstream tail gas system. Condenser temperatures therefore need to be specified in the context of the complete process.
Tube layout and access for inspection
Ruichang’s equipment handbook describes a horizontal, straight-tube condenser with seal-welded tube connections. It also describes removable stainless-steel wire mesh at the gas outlet and access to the tube section and demister.
During equipment selection, confirm the tube arrangement, materials and access openings against the project specification. For a replacement, provide the existing equipment drawing so that nozzle positions and maintenance clearances can be reviewed before the arrangement is fixed.
Liquid sulfur drainage and outlet details
Liquid sulfur needs a clear drainage route to the plant’s collection system. The arrangement described in Ruichang’s handbook includes an outlet sulfur collection channel with a steam jacket, a connection to the sulfur discharge line and a slope toward the outlet to help liquid sulfur drain.
Confirm the outlet elevation, drainage slope, jacket steam supply and connection to the plant’s sulfur collection system on the equipment layout. The support arrangement must also be checked for the specified movement and restraint conditions.
Cooling duty and steam conditions
Steam is generated on the shell side as the process gas cools. Ruichang’s handbook describes different steam pressures for the earlier condensers and the final condenser. Specify the steam pressure for each stage from the process design.
Provide the required gas outlet temperature and the steam system conditions together. Confirm the operating and design pressures, including whether the stated values are gauge or absolute. Final heat-transfer sizing and the steam arrangement depend on the agreed duty.
What to include in a sulfur condenser enquiry
- The condenser’s stage and position on the process flow diagram.
- Process gas composition, flow and inlet temperature at the required operating loads.
- Required gas outlet temperature, operating pressure and allowable pressure drop.
- Steam pressure, boiler-feedwater conditions and available steam for the sulfur outlet jacket.
- The expected sulfur load and the layout of the sulfur discharge connection.
- Design temperatures and pressures, material requirements, design code and inspection requirements.
- For replacement equipment: the current datasheet, general arrangement drawing, nozzle details and inspection findings.
Mark preliminary data and confirm the supply boundary, including whether connecting pipework, sulfur traps or other accessories are required in the quotation.
