Crida EPC Engineering

As the foundation of industrial production and people's livelihood security, the efficient utilization and purification of water resources are of vital importance. Targeting core needs in industrial production such as wastewater discharge, pure water preparation, and circulating water system optimization, we have built end-to-end customized water treatment solutions. Our products and technologies cover multiple links including raw water pretreatment, advanced purification, and wastewater recycling. Through advanced separation, filtration, and disinfection technologies, we significantly improve water quality compliance rates while reducing water resource consumption and treatment costs. Whether it is the treatment of high-salt wastewater or heavy metal wastewater, or the preparation of ultrapure water required by the electronics and pharmaceutical industries, we can provide stable and reliable technical support to safeguard the safety of industrial production and domestic water.

As the global concept of green development takes root, environmental protection has become a core proposition for enterprises' sustainable growth. We focus on the key needs of ecological governance, developing targeted high-efficiency environmental protection technologies and product lines that are widely applied in critical scenarios such as advanced industrial pollutant treatment, industrial waste gas purification and recovery, and soil and water ecological restoration. Our solutions can precisely address the treatment challenges of different pollutants, effectively reducing the emission intensity of waste gas, wastewater, and solid waste. We help enterprises achieve low-carbon transformation goals, balancing economic and ecological benefits while meeting environmental regulatory requirements, contributing professional strength to safeguarding lucid waters and lush mountains.

As a pillar industry of the national economy, the steel industry features complex production processes, high energy consumption, and strict requirements for materials and technologies. We have deep expertise in steel industry application scenarios, providing specialized products and technical services adapted to the entire steel production process, covering key links such as smelting, rolling, cooling, and surface treatment. Our corrosion-resistant materials, high-efficiency additives, and process optimization solutions can effectively enhance equipment operational stability, reduce energy consumption and raw material loss, while improving the surface quality and mechanical properties of steel products. Designed for harsh working conditions in steel production (e.g., high temperature, high pressure, strong corrosion), our products have undergone rigorous testing and verification to ensure consistent high performance in complex environments, helping steel enterprises improve quality, increase efficiency, and achieve green transformation.

As a core pillar of the global energy system and chemical industry, the petrochemical industry covers the entire industrial chain of complex processes such as crude oil refining, petrochemical intermediate synthesis, polymer material preparation, and oil & gas exploration and development. Its production process is characterized by high temperature, high pressure, flammability, explosion hazards, and strong medium corrosiveness, posing top-tier industry requirements for the purity, supply continuity, pressure accuracy, and safety adaptability of industrial gases. Leveraging 6 core technologies including cryogenic separation, PSA/VPSA gas production, and hydrocarbon cracking for hydrogen production, combined with years of project experience in the chemical and petrochemical sectors, SNNA CHEM has developed customized gas equipment and integrated solutions covering the entire petrochemical process, emerging as a core partner for global petrochemical enterprises in achieving stable production, efficiency improvement, and green transformation.

As the core of basic industry, the chemical industry is characterized by complex production processes, high professionalism, and diverse working conditions, which place high demands on the adaptability of technologies and products. Based on the core needs of the chemical industry, we provide customized technical solutions and core products adapted to key process links such as reaction, separation, purification, and synthesis. Our product portfolio covers catalysts, adsorbents, separation membranes, chemical additives, etc., which can effectively improve reaction efficiency, optimize separation effects, reduce energy consumption and impurity content, and help chemical enterprises solve efficiency bottlenecks and quality problems in production. At the same time, we focus on the green and low-carbon development trend of the chemical industry, researching and promoting environmentally friendly chemical materials and clean production technologies, helping chemical enterprises reduce pollutant emissions, lower carbon footprints, and achieve coordinated development of economic and environmental benefits.
