Refinery sour water strippers are an often overlooked resource of low GWP ammonia. Martin A. Taylor and Charles L. Kimtantas of Bechtel Energy Technologies and Solutions, Inc. (BETS) show the results of a study on reusing an existing SWS as one of the major systems in a SWSPlus unit for the recovery of ammonia for sale. Relative cost factors will compare a complete SWSPlus unit versus reusing an existing SWS.
This troubleshooting case study describes an incident at one of the sulphur recovery units at BPCL Kochi Refinery, India. Following a maintenance turnaround of the unit in 2022, unusually high H2 S and SO2 were observed at the outlet of the Claus section. This created an additional load on the tail gas reactor, which led to frequent plugging in the quench column and frequent outages in the tail gas unit, creating environmental and reliability issues in the unit. The activities to identify the root cause of the incident are described and the measures to solve the problem are shared.
The pursuit of operational excellence requires continuous process monitoring, together with qualified analysis of the collected data. The Digital Process Monitor (DPM) provides a process digital twin which consists of an accurate process plant model that incorporates the licensor’s knowledge and expertise in sulphur recovery technology, thereby providing continuous insights into plant performance. This article provides an overview of the DPM features focusing on the related benefits in terms of overall operational improvements and plant efficiency for the sulphur recovery unit.
The refining industry continues to pivot towards Asia, with knock-on effects for sulphur output.
As Comprimo celebrates its 100th anniversary, we explore the group’s history from its earliest days in the Netherlands in the 1920s to its current status as a global leader in gas treatment and sulphur recovery technology.
Ganank Srivastava of Bryan Research & Engineering examines ways to reduce carbon footprint in sour gas facilities.
Though production, particularly from sour gas in Alberta, has declined, Canada remains the world’s second largest exporter of sulphur.
The Aecometric 3rd generation burner was developed, installed and commissioned for an SRU incinerator with increased stringent demands to reduce NOx emission and lower energy consumption. Mason Lee of Aecometric Corporation reports on the new burner design and performance. The emission test results show a significant improvement in addressing these environmental concerns to achieve low NOx (<50 mg/m3 ) combustion and minimise CO (<200 mg/m3 ) emissions.
Sulphur Experts outline the steps required to determine optimised SRU incinerator operating conditions. Although a proper determination of the ideal SRU incinerator operating conditions for any given facility is complicated by a combination of inconsistent permitting standards and poor understanding of the role of the SRU incinerator, the payoff for incinerator optimisation is a significant decrease in natural gas usage with corresponding savings in operating costs, a decrease in CO2 emissions, and a simultaneous reduction in NOx and SO3 emissions.
