Overall Solution for Process Analysis in the Coal Chemical Industry

Coal chemical engineering refers to the process of converting coal into gaseous, liquid, and solid fuels as well as chemicals through chemical processing using coal as a raw material. The main processes involved include coal gasification, liquefaction, dry distillation, tar processing, and calcium carbide-acetylene chemistry. Common coal chemical industries include coal-to-synthetic ammonia/urea, coal-to-methanol/acetic acid, and coal-to-olefins. Ruiheng Measurement & Control, drawing on years of industry experience and technological expertise, fully considers the on-site application environment of coal chemical production. Combined with advanced sample gas treatment systems and high-end detection technologies, we provide enterprises with comprehensive solutions that precisely meet their practical needs.

Metallurgical Industry Solutions

Steelmaking encompasses numerous production processes, including iron smelting, steelmaking, and rolling. During these processes, combustible gases and inert gases are used as fuels or protective gases, while also generating large volumes of process gases. Accurately detecting and analyzing the concentrations of these gases plays a critically important role in optimizing production, ensuring safety, recovering energy, and promoting environmental protection and energy efficiency.

Integrated Process Analysis Solution for the Petrochemical Refining Industry

Oil refining generally refers to the process of petroleum refining, in which crude oil is separated through distillation to produce fuel oils such as kerosene, gasoline, and diesel that are suitable for use in internal combustion engines. The byproducts include petroleum gas and residual oil—components heavier than fuel oils—which are further chemically converted into fuel oils via processes such as thermal cracking and catalytic cracking. Some of these fuel oils undergo additional refining processes, including hydrogenation. The heaviest fraction, known as vacuum residue, is processed through solvent deasphalting to yield deasphalted oil and petroleum asphalt; alternatively, it can be subjected to delayed coking, a process that cracks heavy oils into fuel oil components while simultaneously producing petroleum coke as a byproduct. Lubricant-type refineries employ processes such as solvent refining, solvent dewaxing, and supplemental hydrogenation to produce a wide range of specialized industrial oils, including engine lubricants, machine oils, transformer oils, and hydraulic oils. Today, hydrogenation processes are increasingly being used in the production of both fuel oils and lubricants. Moreover, refineries that supply feedstock for petrochemical production also utilize hydrocracking processes.
