Sulphuric Acid News

Shell Global Solutions International BV (Shell) has awarded Worley two contracts for PT Pertamina EP Cepu’s (PEPC) new sulphuric acid plant in Indonesia. This plant is part of the Jambaran-Tiung Biru utilised gas field project for PEPC, which is a subsidiary of PT Pertamina-Indonesia’s state-owned energy company. Under the contracts, Worley will supply be supplying Chemetics’ cooled oxidation reactor (CORE) technology. This is the first time that CORE will be paired with Shell’s Cansolv SO2 capture technology. Worley gained the Chemetics technology as part of its Jacobs Energy, Chemicals and Resources acquisition last year. Cansolv controls the emissions and captures additional by-product value from the sulphur dioxide emitted from various refinery flue gas streams (such as cracking units, process heaters and boilers), sulphur plants and spent acid regeneration units. Sulphur dioxide can be recycled to the sulphur recovery unit to be produced as marketable sulphur or converted to sulphuric acid.

Start-up, shutdown and turndown

With the ongoing changes in gas field and refinery feedstock compositions, many sulphur recovery units around the world are facing turndown scenarios to such an extent that it is difficult to meet stringent environmental regulations. Equipment and instrumentation behave differently under turndown conditions, and not always in ways that are desirable. Start-ups and shutdowns can place demands on the equipment that are more severe than years of normal operation. In this article, Optimized Gas Treating, Sulfur Recovery Engineering and Comprimo share some of their learnings and experiences of these scenarios.
