Over the past century, the number of sulfuric acid plants operating globally has expanded exponentially. Throughout the 20th century, rapid industrial growth in combination with increasing demand for superphosphate fertilizers led to high demand for the “king of chemicals,” sulfuric acid.
A poorly performing absorbing tower can manifest in poor stack appearance, bad stick test results, bad acid emission testing results, as well as acid sulfate splotches on nearby structural steel members and grade. Absorbing towers are equipped with mist eliminator elements
Elessent Clean Technologies proudly announces a significant milestone in its rich history: 2025 marks the 100th anniversary of MECS® sulfuric acid catalyst products. Since 1925, sulfur burning, metallurgical, spent acid, and wet gas sulfuric acid plants around the globe have relied
Elessent Clean Technologies（Elessent）欣然宣布向市场推出 MENG'S® 技术和产品。这一新品牌将由 Elessent 及其授权合作伙伴提供，主要面向快速发展的中国大陆和印度尼西亚。

随着推动炼油厂减少排放并最终实现净零排放目标的政策变化，一个新的燃料生产时代已经到来。这些政策包括合规碳市场和自愿碳市场，它们在推动炼油厂进行投资以实现更可持续的未来方面发挥着重要作用。碳市场利用税收抵免，向能够以更高效、更可持续的方式生产燃料的炼油厂提供税收抵免。其中一个途径是
碳市场税收抵免的目的是通过减少公用事业产生的排放来提高能源效率。这可以通过测量和优化燃料气体、蒸汽、冷却水和电力等公用设施的消耗量，然后换算成减少的二氧化碳（CO2）排放量。此外，传统的化石燃料原料可以被更难加工的可再生资源原料所取代，例如
这些产品包括植物油、生物乙醇和动物脂肪，但也符合碳市场税收抵免的条件。
未来 10 年，全球燃料市场将发生巨大变化。尽管 2020 年 COVID-19 大流行导致需求急剧下降，但全球液体燃料消费量预计将在 2022 年某个时候超过大流行前的水平。更严格的燃料规格、不断变化的车队、替代燃料日益重要的作用以及原油市场紧缩的可能性，将决定 2030 年及以后燃料市场的发展。欧洲一直在引领使用更清洁、更低排放的燃料。拟议的欧 7 标准将对所有汽油和柴油轿车、货车、卡车和公共汽车的排放水平做出更严格的规定。世界其他工业化地区很可能会效仿。大流行病也加速了去碳化、减少排放和采用可再生燃料的趋势。
烷基化是在硫酸作为催化剂的情况下，由较轻的烯烃和异丁烷反应生成高支链异构烷烃的过程。这种高支链异构烷烃被称为烷基化产品，是一种混合成分，约占美国汽油总量的 10% - 15%。烷基化产品除了能够提高辛烷值和降低汽油的里德蒸气压 (RVP)，还能以零烯烃、零芳烃和低硫的方式减少汽车尾气排放。
催化剂是所有硫酸装置的核心，起着至关重要的作用
对设备性能的影响。本文概述了具体的设计
介绍了杜邦清洁技术公司（杜邦）开发的两种新型 MECS® 硫酸催化剂 XLP-310 和 SuperGEAR™ 的特点，并解释了如何应用这些更先进的催化剂来减少排放或提高硫酸厂的产能。
