A new fully automated process has been developed that combines real time H2 S readings from an H2 S analyser and Q2 Technologies’ proprietary scavenger chemistry to treat high H2 S crude oil on demand. The process provides an efficient and effective way to administer the chemical product to avoid overtreating or undertreating. In some cases, the end user is seeing greater than 50% savings. It is a unique confluence of technology including IoT, advanced chemistry, and oil and gas personnel incentivised to demonstrate continuous improvement.

Russia’s invasion of Ukraine has turned the sulphur market on its head, potentially removing several million tonnes of supply from Russia and Kazakhstan and sending prices skyrocketing.

For some years the fastest growing sector of the methanol market was Chinese olefins production. However, with growth there flattening out, it is traditional chemical uses which are taking over again as drivers of demand growth, with, longer term, a major prospect from fuel and energy applications.

Ammonia synthesis catalysts have seen major improvements over the last 100 years, and they are highly optimised with respect to activity, thermal stability, and poisoning resistance. Improving such catalysts even further requires a deep understanding of their structure and the impact of different parameters on performance. Clariant, Johnson Matthey and Topsoe report on their studies and developments in ammonia synthesis catalysts.

This case study refers to the carbamate condensers and separators in the urea recirculation and hydrolyser desorber section of a urea plant, operating under normal operation at 0.3 MPa and 75°C. After 48,000 hours of operation, during the turnaround of the urea plant, the diaphragm type instruments were sent to the original equipment manufacturer for inspection and refurbishment. In addition to damage of the diaphragm, crevice corrosion was found in the gasket area (see picture) posing a health and safety risk .

New innovations, services and latest technologies to improve the operation and reliability of steam methane reformers from AMETEK Land, Kontrolltechnik, BD Energy Systems, Koch Engineered Solutions, and Quest integrity.

Debora Simoes, Bruno Fardim , and Cleber Vieira of Agroconsult report on what’s driving the Brazilian fertilizer market currently and look at prospects for the coming year.

Mexico supplies more than half of the international avocado market. This oil-rich, nutritious fruit is also widely grown in Colombia, the Dominican Republic and Peru. We look at the nutrient needs of this regionally-important cash crop.

Improvements to equipment and materials are driving greater operational performance and higher efficiencies at urea plants. Recent advances are reviewed.

Correct fertilizer usage at each crop stage can helps avocado growers improve their yield, quality and profitability. ICL’s Mateo Martinez and Alveiro Salamanca-Jimenez explain how growers can supply crop nutrients to avocado trees, efficiently and effectively, using economically- and environmentally-sustainable principles.
