Publication number: 20190143294Abstract: The present invention relates to a process of preparing a chloride adsorbent with natural binder wherein the organic binder is used to bind metal oxide powder altogether and polymethyl methacrylate (PMMA) or carbon black is used as porogen. The chloride adsorbent is then extruded, left at room temperature, dried and burned to form pores. The prepared adsorbent can efficiently remove the chloride compounds in both forms of inorganic chloride e.g. hydrogen chloride (HCI), organic chloride e.g. vinyl chloride (VCI) and trichloro ethylene (TCE) from the hydrogen stream generated from the continuous catalytic reforming unit, in the actual operation in the oil refinery and aromatic substance production facilities. The adsorbent prepared according to the present invention contains metal oxide of zinc in an amount of up to 99.5-99:8% by weight.Type: ApplicationFiled: December 20, 2016Publication date: May 16, 2019Applicant: PTT Public Company LimitedInventors: Ratanawan KIATTIKOMOL, Somrudee PREDAPITAKKUN, Usawadee MAIKHONG, Sumittra CHAROJROCHKUL, Pranuda JIVAGANONT, Theerapron LEUNG ON, Phontip TAMMAWAT

Patent number: 10258955Abstract: Disclosed microscale reactors comprise lamina for carrying out multi-phase reactions for making desired chemical products, such as biohydrogenated diesel (BHD). Microreactor embodiments include a bottom clamp plate, a top clamp plate, and at least one catalyst plate positioned between and operatively associated with the bottom clamp plate and the top clamp plate. Catalyst plates include a catalyst associated for catalyzing the production of product from feedstock. To address the problems encountered when using microchannel reactors, the microscale-based reactors may include a mixer plate assembly and/or at least one catalyst lamina comprising an array of microscale posts. Disclosed microreactor systems for producing BHD include a feedstock source, a hydrogen source and an inert gas source each fluidly coupled to respective microreactor inlets.Type: GrantFiled: November 14, 2016Date of Patent: April 16, 2019Assignee: PTT PUBLIC COMPANY LIMITEDInventors: Goran Nadezda Jovanovic, Frederick Atadana

Patent number: 9521707Abstract: An electromagnetic oil tank heating unit and an electromagnetic oil tank heating system comprising multiple units of electromagnetic oil tank heating units is provided. Each electromagnetic oil tank heating unit comprises a generator capable of generating high frequency electrical current connected to a transformer and a cooling unit, an induction plate with induction coil embedded therein, connected to the transformer and at least one cooling unit, providing cooling to the transformer and the induction plate. The generator, the transformer, the induction plate and the cooling unit are arranged on a frame equipped with wheels to permit mobility of the unit to allow moving the heating unit to a specific location along the length of an oil tank. The frame is configured to include a mechanical means allowing the induction plate supported thereon to move up and down, and forward and backward relative to the oil tank.Type: GrantFiled: April 9, 2013Date of Patent: December 13, 2016Assignee: PTT Public Company LimitedInventors: Wichapun Weerapakkaroon, Cherdpong Jomdecha, Dayin Jearsiripongkul, Chalermkiat Jirarungsatian

Publication number: 20150021859Abstract: Sealing apparatus for applying corrosion prevention compound in the gap between flanges without using heat consists of 3 units including hydraulic power unit, compound injection cylinder unit, and flange belt unit. The present invention is used to apply corrosion prevention compound in the gap between flanges without using heat for melting the compound before sealing. The compound injection cylinder unit comprises two integrally formed cylinders sharing one connecting rod wherein the lower cylinder defines the hydraulic cylinder and the upper cylinder defines the compound injection cylinder. The compound injection cylinder unit is vertically formed on a pushcart provided with wheels for manual transportation. A threaded coupler is provided on top of the lid of the compound injection cylinder for connection with a hose for transferring the compound to the inlet on the flange belt unit. The flange belt unit is provided in various diameters from 2-24 inches.Type: ApplicationFiled: July 18, 2014Publication date: January 22, 2015Applicant: PTT PUBLIC COMPANY LIMITEDInventors: Cheeraporn Ananthanawat, Ungkana Wongsiriwan, Patchareeporn Sintoorahat, Chamlong Prabkeao
