A SYSTEM FOR ENABLING COLD FLOW OF WAX AND HYDRATE PRONE HYDROCARBON FLUID

摘要

A system for enabling cold flow of wax and hydrate prone hydrocarbon fluid is disclosed. The system comprises a cooling cylinder (2) of sufficient length to permit solids to form and deposit on the inside of the cooling cylinder as hydrocarbon fluid passes through the cooling cylinder, a rotatable scraper (4) extending through the cooling cylinder, the scraper in rotation capable of dislodging pieces of solid matter from the deposits on the inside of the cooling cylinder, wherein the scraper is driven in rotation by an electric motor (5) installed in the fluid flow, the motor having an open rotor (15) providing through- flow for fluid.
