Energy recovery continues to be an important driver of project economics. Fertilizer producers face the continuous challenge of balancing overall site energy requirements, especially in large facilities with multiple sulfuric acid production lines, with cost considerations. Over 30 years ago, these challenges led our company to look for step-change improvements in energy recovery based on innovations in materials science.
With 90 references worldwide and nearly 30 years’ proven operation, we are the world leader in HRSTM (Heat Recovery System) technology for sulfuric acid plants. With decades of expertise and multiple systems configurations, we can tailor the HRS™ design to the specific needs of individual fertilizer plants. MECS® HRS™ can be designed to produce steam as low as 4 barg and as high as 10 barg. It is also possible to customize the plant configuration to superheat HRS™ as part of an overall strategy to maximize power production.
We also offer HRS™ systems designed with MECS® steam injection technology, an exciting energy upgrade that has been included in 62 of the 90 sulfur-burning sulfuric acid plants we have designed for fertilizer producers worldwide. Steam injection improves energy recovery, minimizes corrosion and reduces the vibration in the HRS™ diluter.
