    摘要: An apparatus and a method are disclosed for transferring acid catalyst from a transport vehicle where liquid acid is carried under a relatively low vapor pressure level to a process vessel in an alkylation process where liquid acid is contained at a higher pressure level, while minimizing the loss of acid vapor to the environment. The acid transfer is accomplished without venting the process vessel by employing a relatively small volume pressure lock chamber between the transport vessel and the storage vessel. In a preferred embodiment the small volume pressure lock chamber also serves as a storage vessel for make-up acid which is added to the alkylation process as required.

    摘要: One exemplary embodiment can be a barrier for a leak escaping from an alkylation unit. The barrier can include a plurality of members positioned proximate to at least one surface of a vessel in the alkylation unit. Generally, the plurality of members includes at least one first member spaced apart from the at least one surface, and at least one second member distinct from the at least one first member spaced apart from the at least one surface. Typically, the second member has at least a portion closer to the at least one surface than the at least one first member.

    摘要: An improved system for performing an alkylation process and a method for handling liquid catalyst in an alkylation process. This improvement involves method and apparatus by which liquid alkylation catalyst contained in the alkylation process equipment can be transferred into a catalyst storage vessel without the need for venting excess pressure from the storage vessel to atmosphere. Through a combination of the physical arrangement of the process equipment and the storage vessel along with the addition of a pressure equalization line, apparatus is provided whereby certain process steps can be followed which allow the transfer of catalyst from the process equipment to the storage vessel without venting the storage vessel. The improvement comprises physically locating the catalyst storage vessel at a relative elevation below the alkylation proces equipment and providing a line to connect the vapor space of the storage vessel with that of a catalyst settling vessel in the process equipment.

    摘要: An improved system for performing an alkylation process and a method for handling liquid catalyst in an alkylation process. This improvement involves a method and apparatus by which liquid alkylation catalyst contained in alkylation process equipment can be safely stored and isolated from the external environment. Additionally, the apparatus improvement will allow for an improved method for controlling the circulation of liquid alkylation catalyst by providing means for quickly stopping the circulation of alkylation catalyst. The apparatus improvement comprises a baffle contained within a vessel which is attached to the bottom of the vessel and extends upwardly into the vessel. The baffle is designed to allow for the liquid flow between the inside of the vessel and the inside of the baffle and it allows for the venting into a vapor space from the top of the baffle. Within the baffle is standpipe which provides for fluid flow from within the baffle to a region outside the vessel.
