Design for adding electric heat tracing to liquefied petroleum gas pressure storage tanks

Our company has a horizontal LPG pressure storage tank with a capacity of 10 m3; it receives LPG from external sources and uses its own pressure to supply LPG to the vaporizer. At present, this tank is not insulated; during cold winter weather when a large amount of liquefied gas is required, the liquefied gas in the tank cannot be properly supplied to the vaporizer. I am considering adding electric heating and insulation to this tank. What are the requirements for the electric heating design in this case (such as the area covered by the heating elements, the set temperature, etc.)? Any good suggestions would be appreciated! Thank you! Parameters of this tank are as follows: Material: Carbon steel. Medium: LPG (Liquefied Petroleum Gas); the composition of the liquefied gas is C3+C4, with C3 accounting for approximately 15% by volume and C4 accounting for about 85%. Tank design temperature: 50°C Tank safety valve setting pressure: 1.75 Mpa
