Abstract
A reactor system including an enclosed pressure relief system and/or a control system. The enclosed pressure relief system including a slurry separation system communicatively coupled with a pressure relief valve coupled to a loop reactor such that activation of the pressure relief valve results in discharge of a slurry from the loop reactor to the slurry separation system, wherein the slurry separation system is capable of separating solid and liquid components from gas components of the slurry and transmitting the gas components to a flare via a flare header.
Claims20
A system, comprising:
- a loop reactor comprising a settling leg or a continuous take-off;
- a pressure relief valve coupled to the loop reactor;
- and
- a flash chamber configured to receive a discharge stream from the settling leg or the continuous take-off of the loop reactor, wherein the flash chamber is communicatively coupled with the pressure relief valve such that activation of the pressure relief valve results in a discharge of a slurry from the loop reactor to the flash chamber.
A method, comprising:
- receiving a discharge stream from a settling leg or a continuous take-off of a loop reactor at a flash chamber;
- opening a pressure relief valve coupled to the loop reactor when a designated pressure level is reached within the loop reactor;
- and
- venting a slurry from the loop reactor to the flash chamber via the pressure relief valve.
A system, comprising:
- a loop reactor;
- a pressure relief valve coupled to the loop reactor;
- and
- a relief instrument system configured to perform at least one of a high reactor pressure interlock, a high-high pressure interlock, a high pressure isolation of jacket water heating interlock, a high temperature interlock, a high deviation from reactor temperature control set point interlock, or a loss of reactor circulation pump interlock, or any combination thereof.
