Is trace heating required for the breather valve on the sulfolane storage tank?

In winter, it crystallizes, so heat tracing is required. Previously, at a chemical plant I worked at, trace heating was installed on the gas-phase pipes.

The melting point of sulfolane is approximately 28.5°C; it is advisable to heat the breather valve on the storage tank to prevent blockage due to crystallization.
