摘要： The present invention provides a method and reactor system for hydrogenating acetylenes present in the olefin stream derived from the following streams, alone or in combination: petroleum catalytic cracking process and/or oxygenate-to-olefin reactor, such as methanol-to-olefin (MTO) reactor, in an olefin production plant before the distillation steps, wherein the acetylene hydrogenation occurs before or just after the acid gas removal step.

摘要： A system and method are disclosed that allow a user to combine raw light hydrocarbons (e.g., C4 hydrocarbons) and raw heavy hydrocarbons (e.g., gasolines and/or C5+ hydrocarbons) streams together prior to hydrogenation. The system and method allow light and heavy hydrocarbons to be hydrogenated simultaneously within a single reactor. An system and method are also disclosed which provides specific conditions for minimizing light hydrocarbon losses during hydrocarbon processing. In particular, the disclosed method provides pressure conditions in post reactor stabilizers that facilitate venting of un-reacted hydrogen and the condensation of light hydrocarbons. Under the disclosed conditions, light hydrocarbon losses are minimized during the method and the condensed light hydrocarbons can be either recycled back into the system or utilized as a fungible energy source.
摘要翻译： 公开了一种系统和方法，其允许用户在氢化之前将原始轻烃（例如C 4烃）和原料重烃（例如汽油和/或C5 +烃）流合并在一起。 该系统和方法允许在单个反应器内同时氢化轻质烃和重质烃。 还公开了一种系统和方法，其提供了在烃加工期间最小化轻烃损失的特定条件。 特别地，所公开的方法提供了后反应器稳定剂中的压力条件，其有利于未反应的氢气的排放和轻烃的冷凝。 在所公开的条件下，在方法中轻烃损失最小化，并且冷凝的轻质烃可以循环回到系统中或用作可互换的能源。

摘要： This invention comprises a surface heating blanket assembly useful for soil remediation. The assembly principally comprises a metallic furnace belt with tubular electric heating elements inserted between the rungs thereof and making low resistance contact therewith. The furnace belt heater is capable of being rolled and dragged, and flexibly conforms to the earth's surface for maximum heat transfer to the soil. A layer of permeable insulation and an impermeable sheet may be placed on top of the heater. A vacuum may be pulled under the impermeable layer by means of a hole therethrough connected to a vacuum pump.
