Technical grade acrylic acid derived from renewable resources utilizing a base catalyst system by a process including reacting lactide (or lactic acid oligomers) with methyl acetate to form methyl 2-acetoxypropionate in the presence of a base catalyst such as sodium methoxide, pyrolyzing the methyl 2-acetoxypropionate, with or without a catalyst, to methyl acrylate and acetic acid, transesterifying the mixture to acrylic acid and methyl acetate, separating and purifying the acrylic acid by distillation late in the presence of polymerization inhibitor(s). The disclosed process will produce a 'green' (i.e. renewable resources derived) acrylic acid and/or methyl acrylate ester.

A discharge system for removing a solid/gas mixture from a fluidized bed pressure vessel is provided. The system includes a fluidized bed pressure vessel, settling vessels, discharge lines, primary discharge valves, vent lines, primary vent valves, crosstie lines, crosstie valves, and primary exit valves wherein the system is absent a transfer tank, and absent a filter element. The method provides for transferring a solid/gas mixture via a discharge line from the pressure vessel to a settling vessel, wherein gas is separated from the mixture, and the gas is transferred to at least one other settling vessel via a crosstie line. After the solids are transferred out of the settling vessel, the empty vessel then receives gas from other settling vessels in the system.

Discharge system to remove solids from a vessel

A discharge system for removing a solid/gas mixture from a fluidized bed pressure vessel is provided. The discharge system includes a fluidized bed pressure vessel, a settling vessel, a transfer vessel, discharge line, primary discharge valve, and primary exit valve. Also in included is a method to operate the discharge system. The method includes transferring a solid/gas mixture from a fluidized bed pressure vessel to a settling vessel, transferring the solids to a transfer vessel, and then emptying the transfer vessel.

Glyceride-containing feed for a base catalyzed transesterification with lower alkanol to make biodiesel is pretreated with glycerin separated during the transesterification to partially convert glycerides with lower alkanol contained in the separated glycerin using base catalyst in the separated glycerin while reducing the free fatty acid and phosphorus compound concentrations in the glyceride-containing feed. Unique producer compositions are provided by the pretreatment processes.
