CGS ProzessAnalytik - Model Type PIER -Crack Gas Sampling System for Petrochemical Industry
The PIER CRACK GAS SYSTEM is an advanced tool designed specifically for the petrochemical industry, developed through direct collaboration with end-users since 1977. It serves the critical function of gas sampling from cracking or coking processes, which are prevalent in refineries and chemical plants. The system is engineered to meet industry-specific requirements and has been refined over years of practical application to ensure reliability and accuracy in sampling operations. This system plays a pivotal role in providing insights and data essential for refining and chemical processing, facilitating operational efficiency, and maintaining the integrity of industrial processes.
One of the key requirements for improving the profitability of steam cracking is the use of process analyzers for consumption, quality control and for monitoring, managing and optimizing the production process. However, the best analyzer can only deliver correct results if the supplied sample is representative and reproducible and in no way falsified. Only the correct sample extraction, supplemented by the right sample preparation, enables an analysis suitable for process optimization. In addition, taking gaseous samples from a petrochemical process at high temperatures and with high levels of corrosive particles requires cooling and cleaning of the sample in accordance with the specification of the desired measurement principle and the technical specifications of the used process analyzer.
The PIER CRACK GAS SYSTEM has been developed according to the needs of the petrochemical industry, since 1977, in practical collaboration with users, for gas sampling from cracking or coking processes used in refineries and/or chemical plants. Also the trend to crack heavier feed stocks was taken into account in the design phase. The educts here range from Ethane and Naphtha to Waxy Distillate or Vacuum Gas Oil. The design of the PIER System is suitable for use in Hazardous Areas with a high load of corrosive and hot particulate and hot temperatures. Over the past 40 years this Sample Conditioning System (designed and developed by Wilhelm PIER PAS e. K.) has been used worldwide in Cracking Furnaces and is regarded as one of the best and most reliable solutions, money can buy.
The PIER CRACK GAS SYSTEM has a modular design and consists of the following components:
- Mounting nozzle
- Sample gas probe
- Isolation Ball Valve
- Sample gas conditioner
- Sample gas transport line
- System control
- Probe drilling device (if necessary)
- Coolant Recirculator
- Coolant lines
- Coolant
The MOUNTING NOZZLE welded on the transfer line is supporting the probe drilling device or the sample gas conditioner on the sample tap. The mounting nozzle is made of a material that meets the specifications of the process piping and which for sure can be welded on the process pipe.
The SAMPLE GAS PROBE should take the gas sample directly from the flow core of the process line. It is important to ensure that the probe intake does not draw any peripheral gases from the wall of the pipe at reduced flow speed, resulting in a non-representative sample.
The PROCESS ISOLATION BALL VALVE is mounted between the sample gas probe and the sample gas conditioner. The shut-off valve in front of the sample gas conditioning protects the sample system from high steam temperatures when decoking the cracking furnace and enables maintenance work to be carried out during normal cracker operation.
