Advanced Gas Sample Cooling from Perma Pure

Advanced Gas Sample Cooling from Perma Pure

Basics of Gas Coolers

Sample gas coolers are devices used to cool gases or vapors that are being sampled in a process control application. They are typically used in chemical, petrochemical, and refining processes, as well as in power plants and other industrial settings.

Sample gas coolers work by using a heat exchange process to transfer heat from the gas or vapor being sampled to a cooling medium, such as water or air. This lowers the temperature of the gas or vapor, which can be important for several reasons.

First, cooling the gas or vapor can help prevent the sample from reacting with the sampling system or other process equipment. This is especially important when the gas or vapor is reactive or corrosive. Cooling the gas or vapor can also help to prevent it from condensing or solidifying, which can interfere with the accuracy of the sample.

Second, cooling the gas or vapor can help to improve the accuracy of the measurement being taken. Many process control instruments, such as gas chromatographs and mass spectrometers, are more accurate when the sample being measured is at a lower temperature. This is because the measurement can be more stable and consistent when the sample is at a lower temperature.

Overall, sample gas coolers are an important component of many process control systems, as they help to ensure the accuracy and stability of the measurements being taken, and help to protect process equipment from damage or corrosion.

VBall Wafer Style Rotary Control Valves

VBall Wafer Style Rotary Control Valves

S&S V-100 VBall wafer-style rotary control valves utilize a standard ball with a triangular-shaped wedge. Available in 2-inch through 8-inch, they combine precision, accuracy, and control over a full 90° of rotation, functioning as an excellent valve for both throttling control and on/off service and with various actuators. The valve design closes against one of several available ball seals with a shearing action. The S&S V-100 is a flangeless design and allows the valve body to fit between two existing pipeline flanges. The flow characteristic is modified by equal percent, with regular (forward) flow into the convex side of the V-ball. Bi-directional flow is into either side of the V-Ball; TCM ball seal, metal ball seal, or flow ring. Typical actuators used are the pneumatic spring, diaphragm rotary actuator, and the pneumatic piston rotary actuator. Mounting of these actuators can be on the right-hand or left-hand side viewed from the forward flow inlet.

FLO-TITE Industrial Ball Valves

FLO-TITE Industrial Ball Valves

A ball valve is a type of flow control device that regulates the flow of liquid through it by using a hollow, perforated, pivoting ball. When the ball's hole aligns with the flow inlet, it is open, and when the valve handle pivots the ball 90 degrees to halt the flow, it is closed. The handle is parallel to the flow when the valve is open. It is perpendicular to the flow when closed, allowing easy visual confirmation of the valve's status. Ball valves are trustworthy, closing securely even after extended periods of inactivity, and durable, functioning well after numerous usage cycles. Because of these features, they are an excellent choice for shutdown and on-off applications. However, they lack the fine control of other valves in throttle applications.

Flo-Tite Inc. manufactures high-quality ball valves that adhere to internationally recognized standards and specifications, including ANSI/ASME/ISO/NACE and API. They maintain an inventory of standard valves in Carbon, Stainless, Steel, and Alloy 20.

Resistance Temperature Detectors (RTDs) Used in Industry and R&D

Resistance Temperature Detectors (RTDs) Used in Industry and R&D

Process control, instrumentation, and automation applications depend on RTDs (Resistance Temperature Detectors) for various temperature sensing purposes.

Resistance temperature detectors (RTDs) use resistance to determine temperature. RTD sensors in this area are typically made of platinum 100 resistance elements (PT100) and have a resistance temperature curve (alpha or) of.00385/°C (3.851 x 10-3°C-1), although different resistance elements are widely accessible. The resistance of 100 at 0°C is what gives PT100s their name. 

Applications for RTDs are typical in industrial settings such as power plants, refineries, paper mills, food processing plants, and steel mills to monitor the temperatures of process fluids, gases, or equipment surfaces. They have also been used in industrial ovens and furnaces to control the temperature inside them.

RTDs are exceptionally accurate and repeatable at temperatures up to 500°C (900°F). Although RTDs with higher temperature ratings are accessible, their advantages over a thermocouple begin to fade at that point. 

RTDs do not necessitate the use of a properly adjusted lead wire. Three wire structures are most common in industrial applications. Choose four wire structures for the highest accuracy to avoid errors caused by lead wire resistance.

Sanitary Steam Traps and the Role They Play in Temperature Validated Steam-in-Place

Sanitary Steam Traps and the Role They Play in Temperature Validated Steam-in-Place

This video explains the role of the steam trap in successful temperature-validated SIP. Courtesy of Steriflow. Click here to watch video.

Steam trap design and operation play a fundamental role in successful temperature-validated SIP. If the steam trap does not open at the correct time and temperature to drain condensate, it can adversely affect heat-up time and whether the temperature hold is successful. It will negatively affect your revenue because of asset startup delays if it isn't.

SIP (Sterilize, or Steam In Place) is timed sterilization of the upstream and downstream biopharmaceutical production train using clean Steam. It is part of a 5 step sanitization routine that occurs after every production batch and follows the final rinse after CIP (Clean In Place). SIP ensures that every square inch of the production train that comes in contact with drug substance inputs, drug substance, or the final drug product is "sterilized" to ensure no microbiological activity in the system.

Clean Steam (made from USP Purified Water) is circulated through all of the process tubing during this stage and enters large vessels through spray balls embedded in the vessel ceiling.

SIP is a temperature-validated process, meaning that sterilization events are proven by measuring the event's temperature and recording the data. The minimum sterilization regimen requires the injection of clean Steam into all piping and vessels for at least 1/2 hour after reaching a minimum temperature of 250°F (121°C). If the temperature falls below 250°F (121°C) during the temperature hold period, a temperature validation fault gets logged, and SIP repeats.

Validation temperature sensors (usually RTD's) are placed at the condensate outlets of process equipment to ensure that the sterilization temperature meets the specific regimen designed for the process system. The sensing elements are usually designed with integral sheathes and Tri-Clamp™ connections and clamp directly to tubing tees, or the element inserts into a Tri-Clamp™ thermowell connected to the tee. The sensors usually are twelve to eighteen (12 - 18) inches (300 - 450mm) upstream of the clean steam trap where the condensate exits the piping or vessel.

The Perma Pure Hybrid Sample Gas Cooler

Perma Pure Hybrid Sample Gas Cooler

Sample gas coolers condition the sample gas of an analyzing system by passing it through a heat exchanger and cooling it down. Removing any moisture from the gas is a critical step in sample gas conditioning, accomplished by using suitable coolers to lower the gas temperature below the dew point, allowing water to condense. The dew point must be as stable as possible for a repeatable analysis result even when the ambient temperature varies. Sample gas coolers have broad applicability in the cement, petrochemical, steel, power generation, and process industries.

The Perma Pure Baldwin Hybrid Sample Gas Cooler combines the superior performance of Perma Pure’s Nafion™ based drying technology with the functionality of a traditional thermoelectric cooler. Powered by compressed air, this nonelectric cooler achieves dew points lower than 0˚C, helping to prevent problems associated with condensation. The patented mechanical design is ideal for locations with limited or no access to power or other areas where a nonelectric product may be desirable.
