3. Protection Against Contaminants Hydraulic systems are often exposed to dust, dirt, and other contaminants that can compromise performance. Oil seals act as barriers, preventing these harmful particles from entering the hydraulic system and causing wear or damage to the internal components.

- Backup Rings Used to prevent the extrusion of the primary seals under high pressure, backup rings enhance the efficacy of rod and piston seals.

1. Spring-Loaded Relief Valves These are the most widely used type. They operate using a spring mechanism that holds the valve closed until the pressure exceeds the set limit. Once the pressure threshold is breached, the valve opens to allow fluid to escape.

Importance in Natural Gas Processing

The gasification process involves several stages drying, pyrolysis, oxidation, and reduction. Initially, the feedstock is dried to remove moisture, enhancing its energy content. Next, in the pyrolysis stage, the material is thermally decomposed into volatile gases and char at elevated temperatures, typically between 400°C to 800°C. The oxidation stage follows, where a controlled amount of oxygen or air is introduced, allowing combustion to occur partially. This is where the carbon in the feedstock reacts with the introduced oxygen to produce heat. The final stage is reduction, during which the remaining solid char reacts with steam or carbon dioxide to generate the syngas.

2. Plate Heat Exchangers Made up of numerous thin plates stacked together, these devices maximize surface area for heat transfer. They are more compact and efficient than shell and tube designs and are often used in food processing and refrigeration applications.

Neglecting the maintenance and proper implementation of safety valves can lead to dire consequences. A malfunctioning safety valve can fail to open during a pressure surge, leading to equipment failure, safety hazards, and financial losses. In a worst-case scenario, such failures can result in catastrophic disasters, including fires, explosions, and loss of life. Therefore, regular inspection and maintenance of safety valves are critical components of any safety management system.
