Thermal fluid storage done right 🗝️ ✅ Keep all fluid under cover and out of the elements, ideally inside. New fluid stored outside could be subject to water ingress. As air temperature changes, barrels / IBC's will expand and contract. As they contract, any water or condensation sitting on top will siphon into the barrel or IBC, even if it is completely sealed. The once new fluid is now unusable and rendered scrap. ✅Keep a reserve stock of thermal fluid We recommend a minimum of 5% of your system volume. This will keep you covered in the event of leaks, spills and natural evaporation of fluid. ✅Store waste fluid well away from your new fluid reserves Ensure the waste fluid is labelled correctly and clearly to prevent introducing waste fluid into your system.

Pumps in Series vs. Pumps in Parallel: Understanding Pressure and Flow 1. Pumps in Series: - Flow remains constant, but the head (pressure) increases. - Example: - If the flow entering both pumps is [ 500 m³/h ], and each pump adds a head of [ 30 m ], the total head after both pumps will be [ 60 m ]. - The flow remains at [ 500 m³/h ], but the pressure (head) doubles due to the series configuration. 2. Pumps in Parallel: - Head remains constant, but the flow increases. - Example: - If each pump provides a head of [ 30 m ] and a flow of [ 500 m³/h ], the combined flow of the two pumps will be [ 1,000 m³/h ], while the head remains at [ 30 m ]. Summary: - Series configuration boosts the total head (pressure) while keeping the flow constant. - Parallel configuration increases the flow rate while maintaining the same head. #Pumps #WaterEngineering #FluidDynamics #EngineeringDesign #Sustainability #PumpSystems #HydraulicEngineering #EnergyEfficiency

🔥 What is a Fired Heater? A fired heater is a type of industrial heater 🔥 that uses a fuel source 🛢️ to generate heat, which is then transferred to a fluid or process material. It’s an essential piece of equipment in many manufacturing 🏭 and processing industries. Core Components of a Fired Heater: 1- Burners 🔥: The heart of the operation where fuel (like gas or oil) ignites to produce a controlled and efficient flame. Precision in burner operation is crucial for effective combustion and reduced emissions. 2- Radiant Tubes 🌟: Arranged within the radiant section, these tubes hold the process fluid, absorbing heat mainly through radiation from the firebox. 3- Firebox 🏠: The combustion chamber where the magic happens! It's built to withstand extreme temperatures and direct heat effectively to the radiant tubes. Refractory Lining 🧱: This protective layer inside the firebox guards against intense heat and heat leakage to the surrounding, preserving the structure’s integrity and longevity and the unit efficiency. Bridge Wall 🌉: Acts as a partial separator between the radiant and convection sections, guiding the hot combustion gases for optimal heat distribution. it's a critical point to control the furnace though. Shock Bank ⚡: Positioned in the convection section to absorb thermal shocks, protecting the convection tubes from high temperature from radiant section. Convection Bank 🌬️: Harnesses remaining heat in the combustion gases to heat the process fluid through convection, situated above or next to the radiant section. feed usually meet the flue gas here before entering the radiant section. Breach 🚪: The crucial passageway for combustion gases moving from the heater to the stack, ensuring safe and efficient gas flow. Damper 🌬️🔧: Located in the stack, this adjustable component controls the draft and flow of gases, crucial for process control and efficiency. Stack 🏭: The towering structure that releases combustion gases into the atmosphere after they’ve traveled through the heater, also aiding in pulling fresh air into the system. #Process_equipment #Abdelrahman_Alrawi ⭐ #Chemical_engineering_ambassador ✨

#OTCKnowledgeBank - Pressure/Vacuum Relief Valve - How Important is it?🤔 A pressure vacuum relief valve (PVRV) is a device used to protect tanks, vessels, or systems from excessive pressure or vacuum conditions. It is designed to automatically open and release pressure or vacuum when certain predetermined thresholds are exceeded, thereby preventing potential damage or catastrophic failure Pressure relief valve play a pivotal role as a safety net that keep machinery and systems secure and their system pressure under control and in safe pre set level. It fundamental purpose is to prevent disorder when pressure in a system experiences unexpectedly surge. Picture a power facility—without pressure relief valve installed😲 These valves act as protective watchers, automatically releasing excess pressure before it becomes a real issue. Whether labeled as safety valves, safety relief valves, or relief valves, their role remains the same: safeguarding against potential damage and maintaining a safe level system pressure. In simple terms, the importance of pressure relief valves is crystal clear: they ensure a balanced stability, preventing disasters, and keeping machinery and industrial setups running smoothly. It’s not just about machines; it’s about providing a safe environment where operations unfold seamlessly without unexpected disruptions. Its plays a major role in minimizing emission losses of vapors, protecting the environment, reducing atmospheric corrosion of tanks, and maintaining the delicate balance of safety and reliability.

Thermocompressors play a critical role in various industrial applications, utilizing high-pressure motive steam to enhance efficiency. Here's a quick overview of their operation and key maintenance points: How They Work: Thermocompressors entrain low-pressure steam with high-velocity motive steam, combining both to raise the pressure to a required level. This process is efficient due to the transfer of energy through shear, mixing the two streams to create uniform velocity and pressure. Maintenance Tips: Installation: Ensure correct orientation (preferably vertical) for smoother operation and minimize wear. Steam Quality: Dry steam (98% or better) is crucial to avoid erosion of internal parts. Regular Inspection: Annual inspections are recommended, particularly checking the nozzle, diffuser, and other parts for wear or corrosion. Troubleshooting: Low performance? Check for common issues such as low steam pressure, wet steam, or clogged nozzles. By maintaining your thermocompressors properly, you ensure efficiency and long-term operational success.

OPTIMIZING VALVE SIZING: THE IMPORTANCE OF HYDRAULIC DATA 💧🔍 To ensure proper valve sizing, it is critically important to provide accurate information about hydraulic parameters. The following data should be readily available: 🚰 Maximum flow; 💧 Minimum flow; ⬆️ Maximum inlet pressure; ⬇️ Minimum inlet pressure; 🎯 Target outlet pressure. Today, we will discuss the significance of considering both maximum and minimum flow rates. When selecting a valve, it is essential to account for both maximum and minimum flow conditions to ensure stable control in all scenarios ⚖️ Often, pressure regulators are chosen to match the #pipeline size; however, this is not always optimal. The pipeline size might be determined based on peak demand, such as for firefighting needs 🚒 In normal operating conditions, the average steady flow is usually much lower, and the minimum flow is even less. This situation can lead to valve operational issues. Dangers of Low Flow Conditions: ⚠️ Unstable #valve operation; 🔧 Increased wear on valve components; 📉 Pressure fluctuations in the network; 🚨 Higher risk of leaks and failures in the system; 💸 Increased operational and maintenance costs. Possible Solutions: 🔹 Smaller Valve Size: Using a smaller valve size can often be optimal for stable operation and can also help reduce costs! 🔹 Low Flow Devices: Implementing specialized low flow devices can provide stable performance even at minimal required flows. 🔹 Bypass Valves: If the difference between maximum and minimum flow rates is too great for a single valve, a bypass system with a smaller valve can maintain stable control during low flow conditions while allowing the main valve to handle peak flow. There are other solutions available to ensure optimal valve operation under varying flow conditions.

All centrifugal machines can fall into the surge zone. Fans, pumps and compressors are some to name. As flow decreases , the Pd (discharge pressure)/ Ps (suction pressure) ratio increases due to decrease in Ps mainly. Thus when condenser pressure is much higher than suction pressure, the flow can no longer be sustained and refrigerant flows back to the suction side and Pd decreases. As Pd/Ps decreases, the flow direction is reversed again. As speed decreases, the Pd/Ps ratio for surge to occur decreases. Beyond the surge line, other methods of flow regulation comes into play such as inlet guide vane and hot gas bypass control. But IGV and hot gas bypass is not efficient. So, where the Pd value is very high due to high ambient air condition and high wet bulb temperature, speed reduction is limited. Thus the operating range for efficiency (where only speed reduction is deployed) is limitted.

Warming up and keeping warm (PART 2). Several actions can be taken to optimise the thermal behaviour of the pump: Avoid large differences in temperature in and on the pump Thermally separate the cold areas (shaft seal area) from the area through which the hot fluid passes (hydraulic system and balancing device) by means of an insulation chamber system; provide a thermal seal to prevent convection flows and special thermosleeves. Insulate the outside of the pump. Warm up or keep warm the pump by means of forced flow through the machine, usually via throttled pressure supply. Temporarily or permanently interrupt the cooling water supply in the area of the mechanical seal (secondary circuit). Limit the operating parameters for critical operating conditions (ΔT) (top/bottom of the barrel casing) and/or ΔT between casing and feed water. Reduce the effects of large temperature differences  Rotate the pump in stand-by mode using turning gear Employ synchronised turning gear (minimise or prevent actual standstill time) Drain water from critical thermal areas. Select good thermal characteristics when choosing shaft seals Fit a non-contacting seal (floating ring seal) The above measures are frequently used for barrel casing pumps (barrel pull-out pumps) as their outer dimensions, wall thickness, drive (turbine with turning gear) and operating modes are considered more critical than those of ring-section pumps. If possible, these measures are always automated to safeguard the availability of the pump set. Minimum flow valve A minimum flow valve (automatic recirculation valve) ensures a minimum flow rate and thus prevents damage which could occur in low flow operation as a result of either an impermissible increase in temperature leading to vaporisation of the pump content or low flow cavitation.
