What is the theoretical basis for setting the four-stage outlet of the propylene compressor to have high temperatures and high pressures? Is it just for safety?
Isn’t the essential purpose of interlocking safety? Otherwise, why spend so much money to set it up?
Without the interlocking protection device, even the safety supervision bureau will not be able to pass it, let alone the protective equipment to protect yourself.
This depends on the standards. The starting point is to protect the safety of the equipment. The actual operation is to implement according to the standards, and the standards are the theoretical basis.
Chains are all for safety and ensuring equipment
Excessive temperature will cause leakage in weak links at the equipment outlet. The material of the propylene pipeline itself is a low-temperature resistant pipeline and is very brittle. In addition, a high temperature of propylene will cause gasification and excessive pressure, so it is a mutual influence. Personally, I think interlocking is based on protection without being affected by other things. As long as the interlocking value is reached, there will be a response action, which means it is an independent protection. Even if the propylene compressor is in a stopped state, as long as the interlocking value reaches a false signal from the instrument, it will stop, which not only protects equipment, pipelines, but also protects safety, etc.!
