With a total of 2 patents, Sims has focused on enhancing the efficiency of chemical processes in the industry.

Latest Patents

One of Sims' latest patents is titled "Steam cracking of ethane-rich and propane-rich streams." This invention relates to a process for cracking hydrocarbon feedstock that comprises a mixture of ethane and propane. The process involves subjecting the feedstock to a fractionation process to separate it into ethane-rich and propane-rich streams. Each stream is then steam cracked separately under optimum conditions, allowing for the recovery of ethylene and recycling of uncracked ethane and propane. This method significantly increases the yields of ethylene.

Another important patent by Sims is "Polymer cracking." This invention focuses on converting waste and/or fresh polymers, especially polyolefins, into lower hydrocarbons. The process involves vaporizing these materials in a fluidized bed of particulate material in the presence of a fluidizing gas at temperatures ranging from 300°C to 690°C. The resulting lower hydrocarbons can be further processed into useful olefins, paraffins, or waxes, making it an effective method for recycling waste polymers.
