Methods and systems for using temperature measurements taken from a compact insulated skin thermowell to optimize a pyrolysis reaction are provided. In the present systems and methods, the upstream temperature and the upstream pressure of a pyrolysis reactor is measured through an adiabatic restriction in the inlet manifold of a parallel tube assembly to provide an absolute upstream temperature and an upstream pressure. The downstream temperature of the pyrolysis reactor is also measured following an adiabatic restriction to provide an absolute downstream temperature. The downstream pressure is then determined by multiplying the absolute upstream pressure with the quotient of the downstream temperature divided by the upstream temperature as taken to the power of k/k−1, where k is the ratio of fluid specific heat at constant pressure (Cp) to fluid specific heat at constant volume (Cv).

A device for treating crude oil or heavy fuel oil with a method that can lower the pour point to at least 0° C. Crude oil or heavy fuel oil treated thusly maintains this property for at least one year. The device for lowering the pour point of crude oil or heavy fuel oil uses a specific ionization method. The method is conducted by passing a heated medium through the main ionization device which is grounded and which includes three parallelly connected segments whereby each segment includes a protective copper tube inside which a protective insulating shell is situated, inside which a copper housing is situated. In each copper housing there is one cylindrical-shaped external core in which an internal core is placed, and the external core and internal core are manufactured as two different alloys by composition.
