To heat the natural gas, Petrogas designs and manufactures several types of heating equipment such as:
Water bath heater
In a water bath heater or indirect fired heater, the natural gas is fed through a high-pressure tube bundle that is placed in a hot water boiler. A by-pass valve is used for temperature regulation.
In an electrical heater, the natural gas is directly heated by heating elements. Thyristor controllers can be used for temperature regulation.
Shell and tube heat exchangers and hot-water boiler
The natural gas is heated in a shell and tube heat exchanger using a heating medium. A control valve is installed in the heating medium for temperature regulation. The heating medium can be supplied by the end-user. Mostly a hot water generator package will be supplied. The package can be supplied in a custom built container or located in an adjacent building.
