    • A process control technique for upgrading C₃-C₄ hydrocarbon feed containing olefins to produce heavier liquid hydrocarbons comprising converting a major portion of C₃-C₄ olefins in an oligomerization zone by contacting a shape selective medium pore zeolite catalyst at elevated temperature and pressure to make distillate and olefinic gasoline. The oligomerization stage effluent is fractionated to provide distillate and gasoline product and a C₃-C₄ intermediate stream containing isobutane and unconverted propene and butylene. The C₃-C₄ intermediate stream is combined under control with a portion of C₃-C₄ feed and further converting the combined streams in an alkylation zone to make heavier paraffinic hydrocarbons. The olefin feed may be produced by catalytically converting methanol or similar oxygenated hydrocarbons in a known process. Controlled material balance is achieved by accumulating liquid olefin feed to the oligomerization and alkylation units using a surge drum with liquid level control. By-product isobutane is recovered and recycled under liquid level control operatively connected to determine feed of liquid olefin to the conversion units.

    • Flow controller (20) arranged to control flow to a sewage or stormwater system, which comprises at least one reservoir or a stormwater well (2), which via a first pipeline (5) is connected to a controller well (10), in which the flow controller (20) is housed and from which a second pipeline (6) leads on to said sewage or stormwater system. The flow controller (20) comprises a pipe piece (21), which is connected to the first pipeline (5) and opens into the controller well (10). The pipe piece (21) has a substantially horizontal portion, in which from below a vertical groove is cut across the pipe piece (21) on either side thereof up to approximately half the diameter of the pipe piece (21). A vertically displaceable slide (23) extends from below with a disc-shaped portion into the groove. The disc-shaped portion has an upper part with a shape which is complementary to an upper half of the inner cross-sectional area of the pipe piece (21), and a lower part which is so large that it can cover a lower half of the outer cross-sectional area of the pipe piece (21). A float (24) is provided, which is directly connected to the slide (23) and arranged to displace the slide (23) depending on a water level (N2) in the controller well (10).
