■ Product Overview

This atmospheric and vacuum scaling inhibitor is specially developed for atmospheric and vacuum equipment, aiming to effectively address various scaling problems during the operation of the equipment. Through a special chemical mechanism, impurities, salts, and other scale forming substances in crude oil can be inhibited from accumulating and crystallizing on the surface of equipment, thereby forming a solid scale layer. The use of this scale inhibitor can significantly reduce equipment scaling, extend equipment cleaning cycles, ensure long-term stable and efficient operation of atmospheric and vacuum distillation units, reduce production costs, and improve the overall efficiency of refining production.

■ Product Features

Efficient scale inhibition: The unique formula enables it to have excellent inhibitory ability against various common types of scale, such as carbonate scale, sulfate scale, silicate scale, and organic scale formed by colloids, asphaltenes, etc. in crude oil. It can effectively prevent the growth and aggregation of scale crystals, with a scale inhibition rate of over 90%, greatly reducing the scaling rate on the equipment surface.

Wide applicability: Fully considering the complex process conditions of the atmospheric and vacuum distillation unit, whether it is processing light crude oil or heavy crude oil, it can stably exert scale inhibition effect in different temperature, pressure ranges, and device material environments. It has good compatibility with process media and other additives inside the device, and will not interfere with the normal production process.

Excellent dispersibility: Not only can it inhibit the formation of scale, but it also has excellent dispersibility. Small scale particles that have already formed can be stably dispersed in crude oil or process media to prevent further deposition on equipment surfaces, ensuring smooth fluid flow inside the device and reducing operational failures caused by local blockages.

Synergistic effect of corrosion inhibition: At the same time as scale inhibition, it has a certain corrosion inhibition effect on the metal equipment of the atmospheric and vacuum distillation unit. It can form a very thin protective film on the metal surface, effectively slowing down the corrosion of equipment caused by corrosive substances in crude oil (such as sulfides, chlorides, etc.), extending the service life of equipment, and reducing equipment maintenance costs.

Safety and Environmental Protection: The product uses environmentally friendly raw materials that comply with relevant safety and environmental standards. During use, it ensures the safety of operators and poses minimal environmental hazards. After use, there will be no residual harmful substances in the device or environment, making it easy to handle and in line with the development concept of green refining.

■ Scope of application

This atmospheric and vacuum scaling inhibitor is suitable for various atmospheric and vacuum distillation units in refineries, with specific application scenarios including:

Heat exchanger system: Equipment such as crude oil heat exchangers, tower top condenser coolers, and side line heat exchangers in atmospheric and vacuum distillation units. During the operation of these devices, due to factors such as temperature changes and complex composition of crude oil and process media, scale layers are easily formed on the heat exchange surface, which affects the heat transfer efficiency. The use of this scale inhibitor can effectively inhibit the formation of scale layers and maintain the efficient operation of the heat exchanger.

Inside the tower: The trays, walls, and internal components of the primary distillation tower, atmospheric tower, and vacuum tower. During the distillation process of crude oil in the tower, impurities and salts may crystallize and precipitate on the surface of the tower, forming a scale layer that affects the gas-liquid mass transfer efficiency and distillation effect inside the tower. The addition of scale inhibitors can prevent scaling inside the tower and ensure the normal operation of the tower.

Pipeline transportation system: Connect the crude oil transportation pipelines and distillate oil transportation pipelines of various equipment in the atmospheric and vacuum distillation unit. In pipelines, as crude oil flows, scaling substances may gradually deposit on the pipe wall, resulting in a decrease in the inner diameter of the pipeline and an increase in transportation resistance. This scale inhibitor can effectively inhibit the scaling phenomenon in pipelines and ensure the smooth flow of pipelines.
