One way could be to set a timestamp at the point where you set the session for variable_name. This would enable you to compare the current time with the time variable_name was set.

if (!isset(variable_name)) { // optional line if you want to stop the session from resetting
    $this->session->userdata(variable_name, value);
    $this->session->userdata(timestamp_variable_name, time());
}


// Convert 30 minutes into 1800 seconds ...
// Compare the current time with the time the variable was set ...

if (time() - strtotime($_SESSION['timestamp_variable_name']) > 1800)) {
   $this->session->unset_userdata(variable_name);
   $this->session->unset_userdata(timestamp_variable_name);
}
