Cracking in a refinery is a process where the long organic chains in oil are broken to produce shorter chain organics that are more valuable than the oil. Fluid catalytic cracking (FCC) has generally replaced thermal cracking of petroleum hydrocarbon feed stocks. FCC produces more gasoline with a higher octane rating. FCC’s byproduct gases are more olefinic and valuable than those produced by thermal cracking.

Most large coal fired plants have a flue gas desulphurisation (FGD) plant to lower SO2 levels to below emission limit levels. The CODEL GCEM 40 series is used to monitor SO2 levels after the FGD to ensure they are below required levels and to ensure that the process is not too efficient and using too much sorbent. In addition, many plants monitor pre and post the FGD to ascertain the efficiency of the plant.
Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions to the atmosphere. Read about our solutions for aluminum industry!
The shipping industry is continually experiencing regulatory changes driven by increasing environmental concerns, resulting in ever-tightening regulations restricting sulfur (S) emissions from ships' fuel. It has been announced by the UN's shipping agency that the new sulfur IMO 2020 (International Maritime Organizations) guidelines for the sulfur content of marine fuel (bunker fuel) at sea will drop from 3.5 wt% to 0.5 wt% in early 2020. The sulfur content of traditional bunker fuels used in the shipping...
The Clean Air Group, LLC has provided many scrubbers (venturi type, ejector type, packed towers) for the chemical plant area of refineries. These have treated pollutants such as elemental sulfur, maleic anhydride, pthalic anhydride, ethylene oxide, hydrogen sulfide, etc. Our venturi scrubbers can be effectively utilized to handle the off-gases from FCCUs. Other specialized applications (for instance using Stretford Solution in an Ejector scrubber for high efficiency H2S removal) are not unusual for Clean Air...
In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.
Paper manufacturing involves many chemical processes that drive the emission of nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon dioxide (CO2). Nitrogen dioxide and sulfur dioxide are major contributors of acid rain, whereas CO2 is a greenhouse gas responsible for climate change. In addition, wastewater discharge for pulp and paper mills often contains alcohols, chelating agents, and inorganic materials like chlorates and transition metal compounds. Furthermore, chlorine and compounds of chlorine are used...
The low-cost Rigaku NEX QC benchtop EDXRF delivers compliance with the ASTM D4294 sulfur method (also methods: ISO 20847, ISO 8754, IP 496, IP 336, and JIS K 2541-4) with an easy-to-learn software interface in a robust package specifically designed for the petroleum industry. Optimized for routine determination of sulfur in petroleum, including crudes, heavies, bunker fuel, and upgrading operations, the instrument features an intuitive and modern "icon-driven" touch screen interface for easy operation and a...
The presence of hydrogen sulfide in home drinking water supplies is not a health hazard, but is a common nuisance contaminant whose distinctive “rotten egg” odor makes water treatment desirable. Several treatment methods are available, and often hydrogen sulfide can be treated and removed using the same process and equipment used for iron and manganese removal.

Power plants play a vital role. We help minimize downtime while delivering safety and productivity. Whether your power plant serves the needs of ordinary homes, hospitals or factory production lines - the world needs reliable and safe power, and you need profitability. At Endress+Hauser, we bring precision and safety to power plants all over the world.
Many chemical and pharmaceutical plants strive to reduce their overall carbon and water footprint. Paques technologies support this aim through their low energy requirement, the production of green energy, and the recovery of valuable resources.
The Opsis monitoring solution in aluminium smelters is based on either DOAS or laser diode technique. The on-line, open-path systems are used for monitoring HF and sulphur dioxide in potrooms, in fence-line applications and in continuous emissions monitoring. Opsis has long experience of monitoring in aluminium smelters.
Hydrocarbon Processing is one of the most demanding industries in the world. High levels of productivity must be achieved while constantly maintaining the very highest safety standards. Effective gas analysis is a critical component of all HP processes, typically requiring a wide range of measurements to ensure the safe, optimized running of the process.
Biogas is increasingly important as source of sustainable energy. When biogas is produced through any form of anaerobic digestion, it will be mostly polluted with hydrogen sulphide. The concentrations can vary from 200 ppm up to several volume %.
Gas Desulphurisation is notoriously difficult for small to medium sized sulphur sources and for ‘lean’ acid gases in particular. Most other solutions result in either high operational cost or in laborious operations. Or both… This is where THIOPAQ® Oil & Gas offers you a way out.
Tighter discharge consents, reduced energy consumption, reduction of CO2 emission, advanced nutrient removal from effluent, increased capacities and decentralized treatment are the modern trends that waterboards and municipalities are facing. In order to meet new standards, municipalities are looking for specialized solutions.
BCP™ 5000 Series Products offer a solution to sulfur deposition issues that often plague geothermal cooling towers in electric power plants. Geothermal energy systems experience a number of unique operational problems. Fluids produced from geothermal reservoirs include steam, brine and a variety of non-condensable gasses (CO2, H2S, CH3, N2, etc.). In water cooled systems with direct contact condensers, elemental sulfur fouling in the cooling system can be a significant problem.
