Liquid fertilizers are emerging as a high growth, multibillion dollar market. Their growing use is linked to trends such as no-till farming and the greater adoption of precision agriculture. Leading producers and products are highlighted.
Certain fertilizer prices are likely to remain above $1,000/t well into 2023, according to Moody’s.
Meena Chauhan, Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.
Most inspection personnel are familiar with the symptoms of process-related issues; however, they often lack an understanding of the root causes of water-related issues. In this article L. Huchler of MarTech Systems and E. Nasato of Nasato Consulting provide insight about early warning signs of common water-related failures in steam generators and sulphur condensers, proactive monitoring practices, practical operating strategies, options for corrective actions, reminders about robust water-side design and reminders about the challenges of prematurely destroying evidence by prioritising cleaning over diagnostic efforts during turnaround activities.
The economic conversion of phosphogypsum waste into a valuable product has been pursued for decades. Although phosphogypsum is still generally disposed of as waste, industry attitudes are changing and greater use of phosphogypsum will be expected in a circular economy.
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 .
