CO2 emission abatement strategies have become increasingly important as the world strives to combat global climate change. Mahin Rameshni and Stephen Santo of Rameshni & Associates Technology & Engineering (RATE USA) discuss carbon capture options available for sulphur recovery units.
Sulphur run-down lines are typically sized by referencing past projects and ‘rules of thumb’. Very little analysis is performed to identify the impacts of slope, fittings, valves, etc. It is critical to maintain an open vapour path from the condenser to the sealing device. CSI has observed problems in the field which appear to be caused by undersized run-down lines. CSI developed a method of predicting the liquid level in a run-down line that considers the most common elements. This was accomplished by building a full-scale model of a run-down line that evaluated pipe NPS, pipe slope, rod-out-cross elbows, rod-out cross elevation drops, and liquid viscosity. This article* presents the testing and development of the predictive method as well as the predictive method itself.
Advanced Methanol Amsterdam (AMA) is a production facility, that will be realised in the Port of Amsterdam's Biopark, which is destined to produce advanced methanol that meets the European renewable energy directive (RED) requirements. Once completed, AMA will be the flagship production site for GIDynamics and GIDARA Energy and for its High Temperature Winkler (HTW ® ) gasification technology. AMA will also be the first of its kind green methanol unit designed by Casale.

Small, soft fruits such as blueberries, raspberries and strawberries thrive on fertile, well-drained soils rich in organic matter. Their nutrient needs can vary widely according to yield expectations and soil characteristics.
NORAM has recently introduced a patented acid entrainment mitigation device (EMD) to deal with acid mist carryover from sulphuric acid towers.
In its final report on the June 2019 explosion and fire at Philadelphia Energy Solutions in southwest Philadelphia, the US Chemical Safety Board has said that US refineries need to strengthen their safeguards surrounding the use of hydrofluoric acid, and has also recommended that the US Environmental Protection Agency take steps to improve its oversight of the chemical, which is used as an alkylation agent.
A report on CRU’s annual Sulphur + Sulphuric Acid conference, which returned to being face to face meeting at the end of October 2022.
The capabilities of OGT’s ProTreat ® simulator were recently enhanced by the addition of gas treating with hybrid solvents. The functionality was developed generically to make it as broadly applicable as possible. In this article, Ralph H. Weiland of Optimized Gas Treating investigates the effect of TEG as a contaminant on the performance of DEA, MDEA, and piperazine-promoted MDEA in a gas treating application.
New supply-side capacity additions in 2023 will increase export availability from the Middle East. Projects have already been ramping up in Qatar, Saudi Arabia and Kuwait.
