Abstract: Processes are provided for removing contaminants from a refinery gas. Such process can include recovering a process gas comprising ethylene and propylene from a steam cracker effluent recovered from a stream cracker in a steam cracker facility. A refinery gas can be recovered from a refinery facility. The process gas can be compressed in a plurality of compressor stages. A pressure of the refinery gas can be determined. A compressor stage in the plurality of compressor stages can be selected for introducing the refinery gas using the determined pressure of the refinery gas. The refinery gas can be introduced into the selected compressor stage to produce a combined gas that can include the process gas and the refinery gas. At least a portion of one or more impurities can be removed from the combined gas in the steam cracker facility to produce an upgraded combined gas.

Abstract: Processes and systems for C3+ monoolefin conversion. In some examples, the process can include reacting a first mixture that includes C3+ monoolefins and a first oxygenate to produce a first effluent that includes a first ether and <1 wt. % of any first di-C3+ olefin. A first product that includes the first ether and a first byproduct that includes at least a portion of any first di-C3+ olefin and unreacted C3+ monoolefins can be separated from the first effluent. A second olefin mixture, at least a portion of the first byproduct, and a second oxygenate can be combined to produce a second mixture. The second mixture can be reacted to produce a second effluent that includes a second ether and a second di-C3+ olefin. The reaction of the second mixture can produce a greater amount, on a mole basis, of the second di-C3+ olefin than the second ether.

Abstract: Processes and systems for pyrolysing a hydrocarbon feed for a predetermined period of time, e.g., by steam cracking. The process can include determining a first amount of silicon material present in the hydrocarbon feed that is to be steam cracked to produce a steam cracker effluent. The process can also include determining a second amount of silicon material that will be present in a steam cracker naphtha that is to be separated from the steam cracker effluent.

Abstract: The present disclosure relates to processes, apparatuses, and systems for the removal of sulfur compounds from a heavy hydrocarbon feed as part of steam cracking processes to produce light olefins. In at least one embodiment, the process includes introducing a hydrocarbon feed having a first sulfur content to a steam cracker to produce a steam cracker effluent having a second sulfur content less than the first sulfur content. The process includes introducing the steam cracker effluent to a fractionation system to produce a light hydrocarbon product stream having a third sulfur content less than the second sulfur content.

Abstract: A method is defined for inducing a purchaser to visit a store at a remote location subsequent to the purchase of a product from a supplier to pick up or to return the product. This is done by providing incentives to the purchaser to induce him or her to visit an outlet. The level of inducement may be determined by the desire of the outlet to have that purchaser visit their store. Additionally, the method may include inducing a retail outlet to act as a remote location for product pick up or return by the purchaser by providing direct marketing opportunities to the retail outlet. The method offers a unique direct marketing system for general advertisers and allows marketing to an individual known to be coming to a particular location within a known time frame.
