摘要： A portable chemical spill control device includes an expansive sheet of material (preferably multiple layers that include at least one layer of absorbent material) and having upper and lower surfaces and a periphery that defines a circumference. The sheet of material is of a material that is resistant to fluid attacks so that spills deposited upon the upper surface are contained on the upper surface. A peripheral bead includes a foldable portion that extends around the expansive sheet of material, the bead including an elongated tensile member and a folded portion that holds the elongated tensile member to the absorbent sheet of material. A connection joins the peripheral bead to the expansive sheet of absorbent material in a configuration that envelops the tensile member with the foldable portion. The elongated tensile member can be moved between open and folded positions wherein the tensile member subjects the expansive sheet of material to tension in an open position that maximizes its circumference, and wherein in the folded position the tensile member folds to provide multiple loops.

摘要： The present invention provides an integrated system for producing ethylene and propylene from an oxygenate to olefin (OTO) reaction system and a steam cracking system. In a preferred embodiment, at least a portion of an effluent stream from a steam cracking furnace is combined with at least a portion of an effluent stream from an OTO reaction system. Preferably the combined effluent stream is processed by one or more quench units, compression units, and/or fractionation columns. By integrating a steam cracking system with an OTO reaction system, equipment count can be reduced at a significant commercial savings. Compressor efficiency per pound of ethylene and propylene can also be advantageously increased over conventional steam cracking systems. Moreover, the amount of pollutants produced per pound of ethylene and propylene produced can be significantly reduced over the amount of pollutants produced per pound of ethylene and propylene produced in a steam cracking system.

摘要： The present invention provides new highly-efficient separation processes and systems for separating polymerization-grade ethylene and propylene from an initial effluent stream comprising ethane, ethylene, propylene, dimethyl ether, and one or more of propane, acetylene, methyl acetylene, propadiene, methane, hydrogen, carbon monoxide, carbon dioxide and C4+ components. In one embodiment, the initial effluent stream is provided from a methanol-to-olefin reaction system. It has been discovered that an efficient separation of these components is realized when DME is partially removed in a first separation step comprising methanol and water washing steps, followed by separation of the remaining components in additional separation steps.
